Learn How to Buy A Good Laptop Computer

Diposkan oleh ghofar Saturday, May 9, 2009


When buying a laptop, you need to consider factors beyond performance and weight. There are many additional things like screen dimensions, battery life, and keyboard and connection options which you have to think about.Let's look at some of the factors one should consider when buying a laptop.


1. Processor

One of the first things you need to consider in a laptop is the CPU. The latest laptop CPUs include Intel's Core Duo and Core 2 Duo processors which outperform older single-core Intel processors (e.g. Pentium M). Other laptops use the AMD Athlon Turion 64 X2 dual-core processor - which is also a good performer. In general, however, if you're looking for a laptop, I'd advise you to look for one with an Intel Core Duo processor. You can also read this guide to find out more.

2. System memory

The amount of RAM in the laptop is very important. If you're not short of cash, my advice is to get at least 1GB of RAM - that is the minimum you need to get newer PC applications to run fast. Also remember that you can always add more memory to your existing laptop. You may be interested in this short guide on how to install new memory modules into a laptop.

3. Graphics memory

Laptop graphics are another feature you will want to consider. Typically, I'd say you should go for 128MB of dedicated video RAM. Also, ensure that the graphics memory is used solely for graphics use and not shared with the main memory. If you intend to play games on the laptop, then look for advanced 3D graphics chips with about 256MB to 512MB of dedicated graphics memory. Be prepared to fork out a lot more cash though.

4. Screen

You will also want to take a look at the laptop screen. Laptop screens have recently become bigger. Most of them have gone widescreen so you can watch movies or edit spreadsheets more comfortably.
If you intend to use the laptop from home a lot, then I'd go for a 17-inch wide screen. If you are more concerned about portability or if you travel a lot, then laptops with screen sizes of 12.1 or 13.3 inches might suit you better. There are also 14.1- or 15-inch screens for laptops, but I believe manufacturers are shifting away from these models.

5. Battery

Here's another critical factor - laptop battery life. I personally find it very frustrating to have my notebook power run out after 15 minutes at Starbucks. What you need to do is to buy a laptop that has about 3.5 hours of battery life, running on a Core Duo or Core 2 Duo processor. Make sure you question the retailer on how long the battery can last - a short battery life is usually a deal breaker for me.

6. Keyboard and Pointing Device

Some people believe that the keyboard and pointing device on a laptop is important. If you have big fingers, you might be more comfortable typing on a larger notebook keyboard than a small one. Make sure you try the laptop out - get the feel of typing and navigation before you buy the laptop.

7. Optical drives

I'd usually recommend getting a laptop with a rewritable DVD drive as a minimum. One thing you need to know is that some laptops sacrifice a DVD drive in exchange for a lighter weight and portability. If you don't think you need a DVD drive all the time, then you might want to get a model that doesn't have one.

8. Hard drive

In the laptop hard drive department, what can I say? More is better. These days, you can get a notebook hard drives coming in sizes of 160GB or more. You can also get SATA hard drives if you have more cash.

9. Weight

Another thing to note is the weight of the laptop. Now, when you buy a laptop, always remember that the total weight includes the notebook AND the AC adapter, any external modules, and their cables. These can add up to quite a bit of weight.

10. Communications

These days, you will find that most laptops come with at least two USB 2.0 ports - I'd recommend that as a minimum. If you do a lot of video editing, then a FireWire (IEEE 1394) port also becomes essential.
You should also check for good network capabilities. Make sure your new laptop has built-in ethernet capability, a built-in wireless connection and also built-in Bluetooth (if you need to transfer data between your mobile phone and the laptop).
Some of the laptops also include card slots for removable media such as CompactFlash, Secure Digital and MultiMediaCard. If you take a lot of digital photos, then this feature might matter to you.

11. Laptop Shopping Tips

Whew! That sure is a long list of features to consider when buying a laptop. In addition to understanding the features, there are three important laptop shopping tips you should bear in mind.

Tip #1:
How will you use the laptop? One of the problems when you buy a laptop is that you pay for features you don't really need. One of the best ways to avoid paying too much is to consider how you will use the laptop. If it is mostly for word processing, then settle for a cheaper machine. If it is for gaming, then you need a more powerful one.

Tip #2:
Think of features you will not compromise You should also be aware that there are some basic features in a laptop you should NOT sacrifice. For example, for me, if I were buying a laptop, I'd choose (as a minimum) - an Intel Core Duo or Core 2 Duo processor, 2GB of RAM, 160GB of hard drive, a very small screen size and a super long lasting battery. Your list of critical feature may vary.

Tip #3:
Remember you can pick and choose Most vendors will let you custom-build your own laptop. This is a good thing, because you can just pick those features you need and not pay any extra. You can easily purchase a faster notebook by accepting a smaller hard drive or DVD drive, for example.

Conclusion

I hope this article has shown you that ins and outs of buying a laptop. Remember, a laptop is an expensive device. It will also be something you bring along anywhere you go. Hence, it is critical that you do proper research and find the correct laptop to suit your needs. Remember the above tips the next time you're in the market for a laptop, and happy shopping!

Diagnosing And Troubleshooting Computer Hardware

Diposkan oleh ghofar Thursday, May 7, 2009

Are these terms familiar to you? Monitor, RAM, CD drive, CPU, graphic cards are all hardware, or more accurately, computer hardware. These components make up a computer, working together with computer software to make a computer work.
Simply put, hardware is the tangible parts of your computer, parts you can touch, feel and so on.



Hardware Failures

As mentioned before, hardware and software work together to form a fully functional system, theoretically. Sometimes, the originating factor of the hardware failure is not the components of the system itself, but due to outside factors such as environmental disasters like fire, earthquakes and lightning storm.

Recovery of failed hardware components is not a big problem by itself. It is basically identifying and replacing the problematic component. However, hardware failures are most deadly, when it affects daily routine and affecting critical personal or business data. This is especially true of the most important component of a computer system when it comes to storage of data, the hard disk.
The following is a list of common hardware failures:
• RAM Failures
• Power Connector
• Hard Disk
• Overheating
• LCD Failures
• Motherboard
• USB Box

RAM Failures
Bad RAM is somehow harder to diagnose as similar symptoms may be caused by software problems, other hardware problems or even motherboard failure. However if you experience any of these symptoms, users should check for bad RAM before attempting any other troubleshooting.
Symptoms:
• Windows doesn't start showing different error messages each time.
• Windows crashes (blue screen) or freezes frequently.
• Windows crashes as soon as you try to start a program.
• Unexplained random crashes and freezes without error messages.

Power Adaptor

The common weak spot on any laptop is the DC power jack. If someone trips over the power adapter cable while it is still connected to the laptop, there is a high possibility that the power jack will get severely damaged.
On most laptops, the DC power jack is soldered directly to the motherboard and there are only three or four small pins holding it in place, which makes the power jack rather weak. Any sideways pulling of the DC power cord while attached to the laptop will usually dislodge at least one of these pins, breaking the solder around it. Modern laptops use quite a lot of power, from about 70W to 120W or even more. The bad electrical connection from the dislodged pin will cause sparks and heating that will eventually burn a hole through the motherboard and can even be a fire hazard.
Symptoms which indicates poor contact between the DC power jack and the motherboard:
• The battery is not charging properly or stays at half charge despite having to use the power adaptor.
• The screen flickers (the brightness is changing) while the power cord is plugged in. This is caused by the laptop switching between DC power (screen is brighter) and battery power (screen is dimmer).
• The DC plug gets hot after a few minutes of use and may even smell of burning.
• There are "scratching" sounds coming from the DC jack.
How to test for broken power jack:
1. Remove the battery
2. Plug in the power cord
3. Start the laptop
4. Gently wiggle the DC power plug on the back of the laptop
If the laptop shuts down abruptly (looses power), find the dealer to re-solder or change the DC power jack as soon as possible as the motherboard has already started to burn around the dislodged pins. The manufacturer might offer to replace the whole motherboard; however the price of a new motherboard together with the labor charge for installing it will usually cost more than the current value of that laptop and sometimes can the pricing can cost over a thousand dollars.
Replacing or re-soldering the DC power jack is not an easy job. To reach the power jack, the laptop has to be completely disassembled and have the motherboard taken out. Then if the board around the dislodged pin is badly burned, the power jack has to be un-soldered and the board has to be patched.
After that a different power jack has to be installed, attached to the case of the laptop and connected with wires to the motherboard, as the patched board wouldn't be strong enough to support the original type of power jack that was soldered directly to the board.

Hard Disk

Hard disk failures are the most common computer hardware problems. And laptop hard disks fail more often than desktop hard disks due to the portability of a laptop as compared to the rather stagnant laptop. If user knock hard or drop the laptop even a few inches while the hard disk is being accessed or powered up, damage can be done to the hard disk.
Symptoms:

• The laptop starts as usual but when Windows starts to load it goes to blue screen with either "UNMOUNTABLE_BOOT_VOLUME", "hal.dll is missing or corrupt" or "WINDOWSSYSTEM32CONFIGSYSTEM" (or similar) is missing or corrupt. All these error messages indicate a file system problem. The laptop starts as usual but Windows freezes on the initial "Windows XP" screen, although the blue bar continues to move, and users are able to hear feint but continuous clicking. Hard disks have to be replaced.
• As soon as the laptop is started there are loud clicks or grinding sounds and Windows doesn't load. Hard disks have to be replaced as well.
• Shortly after starting the laptop a message appears (usually on a black screen) "SMART test failed. Backup your data immediately and replace the hard disk" or similar.

In almost all cases the laptop can be started from a "live" bootable CD and everything works normal. In rare cases the hard disk PCB (printed circuit board) may get short circuited and even burn. In this scenario, the laptop won't start unless the hard disk is removed.
A good tool to use to check for hard disk lifespan is ADRC's hard disk checker. It will scan the hard disk for bad sectors and inform you if the drive is still of good usability.

Overheating
Overheating happens when inadequate airflow from outside the computer's case across the CPU and motherboard and back out of the case usually via the power supply fan and other case fans.
Once the airflow is disrupted, heat builds up rapidly within the case. This causes components to either shutdown, if such protection is built in or performs erratically. Over the long term, overheating can irreversible damage components.

LCD Failures
The most common LCD or "Liquid Crystal Display" screen failure is the inverter, cable and backlight.
Symptoms:
• The laptop appears to start as usual but the screen is black, if users move it, it turns on and works properly. Failed cable.
• The laptop appears to start as usual but the screen is very dark, although it changes colour a little and users can see a very feint image. Failed inverter or cable 90%/10%.
• Immediately after starting the screen has dark pink/red tint and turns dark after a few seconds. Failed backlight.
• The screen flickers a few times but then turns dark, if users move it or tap it lightly on the sides, it flickers again. Failed cable or LCD 50%/50%.
• Screen is either black or white (no picture) and external monitor works. Failed cable or LCD 30%/70%.
• There are stripes on the screen (either vertical or horizontal) that change when users move the screen or tap it lightly on the sides. Failed cable or LCD 10%/90%.

Motherboard
Most motherboard related failures are due to the "On-board" regulated supplies and component failure within those circuits. The on-board power supply circuit had partially failed and was overloading subsequent components else the problem would be with the capacitors which are defective in the first place.
A motherboard failure on a laptop that is out of warranty would usually mean that it's time for a new laptop. The price of a new motherboard is usually higher than the current value of the laptop.
Symptoms:
Plug in the power adaptor and try to start the laptop.
• Nothing happens.
• The "ON" light comes on, the fan spins, but nothing on the screen (black) and you can't hear the HD working after 10-15 sec.
• The "ON" light comes on, the fan spins, but after a few seconds the light goes off.
• After pressing the "ON" button the screen stays black and you can hear a quiet high-pitched sound coming from the laptop.

Corrupted or improper device drivers and operating system

Invalid or corrupt device drivers can wreck havoc on a server, rendering the system unbootable in some cases. Device drivers may also conflict with certain application programs and cause problems with the computer system.
As Windows Vista has just made its launch, chances are some hardware is not supported or not supported fully by the new operating system.
Also, system updates, driver updates can also fix your "hardware" problems.

Controller Failure
A controller failure can act much like a drive failure. However, when a drive fails, users cannot access that particular drive; when a controller fails, users cannot get access to all the drives, devices and any other components that is attached to that particular controller.
A controller fails because a component or components on the on the controller board fails. When users trying to boot the system, they cannot switch on, view, access, or even get hardware conflict messages.
Controller failure occurs due to one of the following reasons:
• Devices/components not connected properly
Verify that the cables are properly connecting the device /component to the controller
If the component fits into a slot, see that the it is flushed in and not loosely connected.
• Devices/components not setup properly
Verify that the devices/components is being properly detected and setup in the respective controller setup screen
• Bad connectors
Replace the bad connectors with new working ones
• Bad components
Replace the component
• Bad interface board or motherboard
It is recommended that these components be replaced or that the computer be sent in for servicing

HOW TO BUILD A SILENT PC OR HOME THEATER PC

Diposkan oleh ghofar Thursday, April 30, 2009

A home theater PC, or a media-center PC, is a home computer and A/V receiver combined for entertainment, similar to traditional home theater systems. Available are entertainment related upgrades that will make it into a home theater system, with progressive scan DVD playback, over the air HDTV support, and surround sound inputs with less fan noise. Also are the same computing functions, video a bilities, and media storage. If the home theater is already hooked up in the home, the addition of the right PC to it can add even more benefits to this investment. If not, then adding a PC to the home theater system will add benefits to an already existing set up. An example is that if we were an advanced gamer, we certainly will enjoy the gaming abilities that we have when it comes to the new addition. to make home theater necessary payed as follows :


Step 1 – Choose your case.

While the availability of small form factor PC cases are becoming increasingly widespread, as is the availability of small form factor motherboards and components, the choices aren’t as varied as standard size cases and components. Also you’ll find that small form factor components tend to be more expensive.
Cramming the latest technology into a tiny case inevitably puts components that generate a huge amount of heat (CPUs, graphics cards, northbridge, etc) closer together which then puts a greater emphasis on cooling. While you could cool the tiny rig with large fans you then encounter another problem, sound. Ditch the dreams of an ultra small HTPC because it’ll just cause you headaches. If your case is going to be on show it’s a good idea to choose your components so that they match colour-wise.

Step 2 – Choose Your Processor.

There are only 2 manufacturers of processor that you should consider; Intel and AMD. Personally I have always gone for AMD processors with self build projects, they perform on par with Intel processors and are generally cheaper when compared like for like with the Intel chips. Your choice of speed of processor is entirely up to you, some people like to go for the fastest they can afford, while it is true that you need a fairly fast processor you don’t need to go overboard if you’re just using the your media center PC in the living room to watch TV and listen to music. If you plan to use your media center PC for anything else such as games o r video editing then you ought to really focus on buying an upper range model of processor. In my HTPC I opted for an AMD Athlon XP 2400+. This processor is by no means fast by today’s standards but it performs the job well using Windows Media Center 2005 (and Windows Vista) and even copes fairly well with the games that I run occasionally.

Step 3 – Choose your motherboard (or mainboard).

The motherboard will be your key purchase, it might not be the most expensive component but choosing a motherboard wisely can max imise the performance of all the other components that are going to attach to it. Your choice of motherboard will be primarily determined by your choice of processor. If you have chosen a AMD XP 2400+ processor like the one I have t hen you will need to choose a socket A motherboard. If you have chosen a newer AMD processor like the AMD Sempron 3600+ for instance, then you will most likely need a socket 940 motherboard. If you’ve chosen a newer Intel processor like the Pentium D 930 then you will most likely need a socket 775 motherboard. Look at the manufacturer’s documentation that accompanies the processor and it will tell you which socket of motherboard that it will fit into. Please note that you must buy the right motherboard that will fit your processor, otherwi se the two will not fit together in anyway and they will be entirely incompatible.
Now you have determined which ‘socket’ of moth erboard you need it’s time to shop around. Make sure you buy a motherboard with a decent chipset manufacturer such as Nvidia (nforce chipset), Intel, or VIA (the chipset of the motherboard is handles data traffic between your processor, memory, and any peripherals you may have installed). If you plan to use your Media Center PC primarily for watching TV and listening to music then you might want to consider opting for a motherboard with on board graphics (graphics card built on to the motherboard), on board sound card, and on board LAN/wireless card. If you’re going to use your Media Center for games at any point then my advice would be to choose a motherboard that doesn’t incorporate on board graphics as the on board graphics built in to motherboards, though they will perform the job of displaying video adequately, don’t tend to be t hat powerful when it comes to gaming. You could also opt to have a separate sound card that provides higher quality sound it all depends on how serious you are about the sound that’s going to be coming from your HTPC, for most I think the onboard sound would do (tip: whether going for onboard sound or a separate sound card, make sure it’s capable of at least 5.1 surround sound for use when watching DVDs. Even if you only plan on using 2 speakers, these cards can be configured for 2 speaker output). In my HTPC I opted for the MSI K7N2 Delta-L socket A motherboard. It ca me with onboard LAN and onboard 5.1 sound but I chose to add a separate sound card for reasons I shall divulge later.



Step 4 – Choose your hard drive (HDD).

Don’t be tempted to go for the 10,000 rpm models of hard drive though as they are louder and generate a lot of heat, you probably won’t notice much of a performance gain by using this type of hard drive in a Media Center environment anyhow. In my setup I went for the Maxtor Diamondmax 10 300gb 7200rpm IDE hard drive which is plenty space for all my film recordings and music, I also use my Media Center PC as a file server for my other PC and laptop, so my suggestion is that around 300gb of hard drive space will suffice. Be sure to choose the type of hard drive interface connection that suits your motherboard, i.e. if your motherboard supports the SATA interface choose a hard drive that also uses the SATA interface. Hard drives are also a big contributor to the noise and heat problem, it might be a wise idea to invest in a hard drive silencer/cooler, I want my HTPC to be as quiet as possible so I went for the Scythe Quiet Drive which is a HDD silencer and cooler all in one.

Step 5 – Choose your memory (RAM).

If your motherboard says it supports DDR400 then this means that it only supports RAM which is Double Data Rate (DDR) and will only support speeds of RAM up to 400MHz (yes RAM has a speed it operates at too). In some cases if a motherboard says it supports up to DDR400 it also means that it will support the formats below it, for example; a DDR400 motherboard may also support DDR333, DDR266, and DDR200 RAM modules. The idea behind Dual Channel RAM is that you install 2 identical RAM modules on you motherboard in the banks that are designated for Dual Channel operation. The data that comes from your processor is then effectively split into 2 parts, the 1st part is sent to the first RAM module and the 2nd part is sent to the other RAM module. Once you have determined the speed and type of RAM you need it’s time to look at how much RAM you actually need. I have used a Corsair 1GB DDR 400 Dual Channel kit (2 identical 512MB modules of RAM) in my setup and it manages perfectly well.

Step – 6 Choose your DVD Drive

This is quite straight forward as you will need a DVD drive that can read all available formats of disc and also able to write to all formats of disc for when you need to backup films or music, pick a DVD that writes Dual Layer +R and –R formats..Generally a good make of DVD burner that will write all formats costs around £30.

Step – 7 Choose your graphics card.

If you have gone for the motherboard with on the on board graphics then you can skip this part as it doesn’t apply. If you have chosen to go for a separate graphics card then I assume it’s because you also intend to use your Media Center PC for games. Graphics cards are renowned for have the worst sounding cooling fans that whine at just the right pitch that it drives you mad. If you have chosen to go for a separate graphics card then it might be worth spending that bit extra and buying a fanless heatsink to go with it. Also worth noting is the different sorts of output present on the card such as S-Video etc, as this will determine if the card is compatible with the inputs on your current TV.

Step – 8 Choose your power supply.

Remember generally speaking power = heat = noise due to cooling. If you have an unlimited budget then I’d tell you to go for a fanless power supply as these are ideal, they generally have large heatsinks and use heat pipe technology to dissipate the heat. My recommendation would be to go for a power supply with a fairly large power rating that is billed as ‘silent’ and contains a 120mm fan. Remember that you need a power supply that can provide more power than the sum of the maximum power ratings of all the components that make up your system. My general experience with power supplies is that you can’t really trust what it says on the box. In order to achieve a near silent power supply using a large fan it really is a case of you get what you pay for. In the case of so called decent ‘silent’ power supplies I think people are being charged over the odds for what is basically a bog standard power supply with a slightly better fan (no doubt someone will point out to me the other factors which justify power supplies costing more). With this in mind I took my 500W Qtec ‘silent’ power supply with 120mm fan which cost £15 (this power supply is about as far from silent as possible!) and exchanged the fan for a truly silent Zalman Silenx Vario 120mm fan from Puresilence. Hey presto, a very very quiet power supply and all it cost was £25 in total and a bit of screwdriver action!
*DISCLAIMER* If you choose to swap out the fan in your power supply to one other than the manufacturers’ specifications then you do so at your own risk. Step 9 – Choose your Cooling.
While also being as quiet as possible i.e. the bigger the fans the better, bigger fans = slower rotation (while still providing the same throughput of air) = less noise. You also might want to think about swapping the standard heatsinks, that come with your processor, northbridge chipset, and graphics cards to fanless ones. I already chose a graphics card that came with a fanless heatsink so it was just a case of finding a suitable fanless heatsink for my processor and northbridge. There were many options to choose from but I opted for the Thermaltake SilentTower which cost £20 from DCS Doncaster for my processor because it will run perfectly well fanless but also allows you to add 2 large 90mm fans for extra cooling should you want to. For my northbridge I opted for the Zalman ZM-NB47J Silent Motherboard Heatsink which was £6.00 from QuietPC. Of course if you’re going to use fanless heatsinks in your setup then this puts even more emphasis on the need for case fans, if you don’t have adequate heat exhaustion in your case then the heat from your heatsinks will warm up all the components in your system and thus compromises performance, or worst case scenario a component fails. If you need to buy quiet fans I recommend the Pure Silence website. I bought one of the 120mm silent fans from their site to replace the one in my power supply and I can confirm that they are deathly silent.
I also recommend that you buy a fan speed controller, this is a device that usually fits into one of the 5.25” drive bays on the front of your PC, it allows you to control the exact speed of all your fans, i.e. you can make you PC as quiet as you like but also be able to ramp up all the fan speeds should you need that little bit of extra cooling.
I opted for the Thermaltake Hardcano13 which cost £36.75 from DCS Doncaster as it matched my case and also came with a built in card reader to boot.

Step 10 – Choose your TV tuner card.

There are many different options you can go for when choosing a TV tuner card. Some cards have just a single analogue tuner, some have digital HDTV capabilities, some have 2 tuners on the same board so you can watch 1 channel while recording another, and some are combinations of the previous. Bearing in mind that all TV is due to switch to digital transmission in the UK, and the advent of digital HDTV, I opted for the Dvico Fusion dual HDTV DVB-T tuner which cost £114.95 from theglowlounge. This card comes with a well built remote, works brilliantly, and also has AV input, you can read a detailed review of this card at johnsreviews.

Step 11 – Choose your control device.

Now that you have chosen all the necessary components it’s time to choose your control devices. Most media center remotes will do the job, it’s all down to a matter of personal taste.

Step 12 – Assembly.

Well I could spend another month writing pages and pages of instructions on how to install every component and configure the PC for optimal performance but I think the following videos can explain it just as well and in less time!

KOMPONEN KOMPUTER (HARDWARE)

Diposkan oleh ghofar Tuesday, April 28, 2009

Hardware computer adalah bagian fisik dari sebuah computer atau system peralatan yang digunakan untuk menjalankan fungsi computer. Perkembangan teknologi elektronik yang paling pesat dan banyak dipakai dibanyak bidang dalam menyelesaikan pekerjaan maupun untuk memperoleh informasi tidak lain adalah computer. Pengertian komponen komputer


Komputer terdiri beberapa bagian yaitu :

1. Motheboard

Mother Board merupakan board/papan induk atau main board dimana semua device dipasang mulai dari processor, memory, slot-slot untuk ekspansi, dll. Mainboard tak kalah penting dengan prosesor. Jika dimisalkan pada manusia, mainboard adalah rangkaian pembuluh darah dan jaringan urat syaraf pada computer. Mainboard yang kurang baik, akan mengakibatkan tidak maksimalnya kinerja peripheral lain. Oleh karena itu, pemilihan mainboard yang tepat akan sangat mempengaruhi kinerja computer.
Cara Kerja Motheboard Dalam system computer, peripheral-peripheral akan saling terkoneksi di dalam mainboard dan dapat meneruskan instruksi melalui jalur-jalur pada board. Seluruh peripheral yang terkoneksi akan menjadi sebuah system computer yang utuh. Sementara fungsi mainboard pada umumnya adalah menyalurkan arus input dan arus data yang diperlukan pada jalannya proses di dalam computer.

2. Prosesor
Merupakan bagian utama dari computer karena processor berfungsi untuk mengatur semua aktivitas yang ada pada computer. Satuan kecepatan dari processor adalah MHz ( Mega Hertz ) atau GHz ( 1000 MegaHertz ), dimana semakin besar nilainya semakin cepat proses eksekusi pada computer. Processor dapat kita analogikan sebagai otak dari computer. Hardware ini berfungsi untuk melakukan segala macam proses dalam system computer. Sehingga processor sangat menentukan kecepatan dan performa system computer.
Cara kerja Prosesor Dalam kenyataan di dalam system computer kita tidak dapat melihat secara kasat mata bagaimana cara kerja prosesor. Namun pada saat computer bekerja, prosesor sebenarnya melakukan pemrosesan aritmatika dan pengendalian operasi computer secara keseluruhan sesuai dengan instruksi yang diberikan oleh user.

3. Memory (RAM)

Memory menurut arti katanya berarti tempat penyimpanan. Digunakan untuk menyimpan informasi/data baik sementara ataupun permanen. Ukuran memory didasarkan pada kapasitas penyimpanannya yang bersatuan Byte. Memory adalah ruang simpan sementara dalam chip computer. Tipe-tipe Ram yaitu EDORAM, RDRAM, SDRAM, dan DDR-SDRAM.

4. Hardisk

Hardisk adalah storage devices yang paling sering di pakai. Bagian-bagian hardisk terdiri dari Logic board, motor, Platter, read-write head, interface slot, dan body. Logic board merupakan bagian hardisk yang mengatur kerja hardisk menurut instruksi dari user. Logic board ini nantinya mengatur putaran motor dan gerak dari read-write head menurut lokasi penempatan data. Read-write head inilah yang membaca dan menulis data pada hardisk, menyampaikan informasi kepada logic board, kemudian logic board menyampaikan kepada CPU melalui interface baik itu SATA maupun PATA. Harddisk banyak menangani program dan menyimpan data di komputer. Untuk alasan ini harddisk memiliki kapasitas simpan yang besar. Kapasitas simpan harddisk bertambah dengan pesat dari 40 MB hingga 80 Gb. Biasanya kapasitas simpan harddisk diukur dalam satuan gigabyte.

5. Optical Drive

Pada proses instalasi, kita membutuhkan sebuah media untuk memulai booting komputer yang belum memiliki sistem operasi. Untuk beberapa master software, kita membutuhkan data yang read only / tidak dapat dirubah / termodifikasi oleh sistem lain. Pada zamannya, untuk pertukaran data menggunakan kepingan CD/DVD lebih praktis daripada harus membawa hardisk. Kita membutuhkan backup data yang aman. Pada penyimpanan di hardisk, kita masih terancam kehilangan data karena rusaknya hardisk akibat bad sector atau faktor lain, ancaman virus yang seringkali merusak data pada hardisk, atau modifikasi data oleh orang lain yang menemukan file kita secara sengaja atau tidak sengaja.
Macam-Macam Optical drive

1. CD ROM

CD-ROM adalah perangkat optik yang hanya dapat digunakan untuk membaca CD saja. Perangkatnya berisi optik, motor, tray, dan case. Pemilihan CD-ROM ini berdasarkan kecepatan bacanya. Pada zaman dahulu CD-ROM hanya memiliki keccepatan baca 1x, 2x, 4x, 12x, namun kini CD-ROM telah mampu melakukan pembacaan hingga 56x.
Kebanyakan software yang ada pada saat ini berada dalam CD-ROM. Hal ini karena CD dapat menangani data lebih banyak, sampai 700 Mb tanpa kompresi data. Saat ini CD merupakan pilihan yang efisien dan ekonomis.

2. CD RW

CD-RW adalah perangkat yang mampu melakukan pembacaan dan penulisan terhadap CD. Artinya kita dapat menyimpan data kedalam sebuah CD blank. CD-RW biasanya memiliki 3 variable yaitu write/rewrite/read. Misal CD-RW 52x/32x/52x berarti perangkat tersebut memiliki kemampuan tulis 52x, kemampuan menulis ulang/menindih 32x, dan kemampuan baca 52x.

3. DVD ROM

DVD-ROM adalah perangkat optik yang mampu membaca CD dan DVD. Bedanya dengan CD adalah DVD berisi data lebih banyak, yaitu + 4,5 GB. Kecepatan baca DVD hingga kini masih 16x, namun DVD-ROM mampu membaca CD hingga 52x.

4. DVD COMBO

DVD-Combo adalah perangkat yang memiliki gabungan fungsi 2 macam perangkat yaitu DVD-ROM dan CD-RW. Kemampuannya yaitu dapat membaca CD dan DVD, serta mampu menulis pada keping CD.

5. DVD RW

DVD-RW merupakan perangkat tercanggih di kelas optical drive masa kini. Perangkat ini dapat melakukan pembacaan DVD dan CD serta mampu melakukan penulisan pada CD dan DVD. Kecepatan penulisan DVD hingga kini masih 16X saja
