Computer Specifications

You are wondering maybe like me before what the specs of computer you are going to buy, or may be wondering what all this CPU, RAM, ROM, 24X, 128MB, SPEED, MODEL, etc.


If there are any specific programs that you know and you want to run, such as a gaming, digital imaging or designing or you need a computer for animation, you have to verify what the system you need to buy meets those requirements.
Have you thought below contents, what is about, what the goal and what is this?

Processor Speed
  • The measure how quickly the  central processing unit or CPU (aka the microprocessor) performance or speed depends on e.g. the clock rate and the instructions per clock (IPC), which together are the factors for the instructions per secon (IPS) that the CPU can perform.
  • The speed of the CPU is how fast the CPU can access and process information, which translates to how fast you can work on your computer.
  • CPU is like the brain of the computer. If you want the machine to think quickly, you need to have a fast processor or clock speed.
  • The greater the number of GHz the faster the PC and the more expensive the processor will be.
RAM
  • RAM (Random Access Memory), manyt times just called memory, is a form of computer data storage.
  • RAM works with the CPU to manage all your open programs and improve the speed at which each process can run.
  • In earliest time RAM is usually measured in megabytes (MB) but today gigabytes (GB) are appearing on the market.
  • Most basic computers will come with at least 256 MB of RAM and most users will want at least 512MB, while gamers and people who do graphic-intensive work (photo, business, editing, etc.) will want at least 1024MB (1 GB).
  • But computers now have 2 to 4 GB of RAM. 

Processor Make and Model

  • Gigahertz vs Megahertz
    1 Gigahertz(GHz) = 1000 Megahertz = 1000000Hertz
    and one hertz is the equivalent of processing a single piece of information.
  • Ten years ago computers had processors running at 10Megahertz. Now we have computers running at faster than 3 GHz ie 300 times faster.
  • Check below name and links for sample:  
           Athlon AMD Athlon 64 3500+ Processor Socket 939


   Forget about their names, just go for the highest speed processor or better

Hard Drive
  •  A hard disk drive (hard disk, ard drive, HDD) is a non-volatile storage device for digital data. It features one or more rotating rigid platters on a motor-driven spindle within a protective enclosure. Data is encoded magnetically by read/write heads that float on a cushion of air above the platters. (read more from wikipedia)
  • It is now measured in gigabytes (GB), although terrabyte (TB, equal to 1000 GB) external drives are just starting to become widely available. Half-TB (500 GB) external drives are common.
  • Today's minimum requirement is least 120 GB for average users who want to store music or photos on their computers. Of course you can go as high as you want if you are willing to spend the money on large drives or multiple drives.
  • Large drives are good if you plan to store your DVD and music collections on a computer and use it as a media center.
(I advice that don't use 1TB for personal storage, use 3X or buy 3 500 GB or it's up to you, I'm telling only to avoiding viruses) Search Amazon.com for hard drive


CD/DVD Drives
  • If you plan to burn anything, check for an integrated DVD/CD-R/CD-RW drive.
  • Some offer CD burners only (CD-Recordable or CD-ReWriteable), and others offer both a CD-RW plus the ability to watch DVDs 
  • Check this: Search Amazon.com for cd dvd drive 
Graphics Card
  • A video card, video adapter, graphics accelerator card, display adapter, or graphics card is an expansion card whose function is to generate output images to a display.
  • A video card enables a computer to process and display images on a monitor. It does this by converting binary data into images. Software that displays graphics requires a video card with certain specifications.
  • Higher processor speeds are needed, as is more memory.
  • Check for system requirements and compatibility between programs/games that you plan to use before buying a computer.Search Amazon.com for Graphics Card
Sound Card
  • A sound card (also known as an audio card) is a computer expansion card that facilitates the input and output of audio signals to and from a computer under control of computer programs. Typical uses of sound cards include providing the audio component for multimedia applications such as music composition, editing video or audio, presentation, education, and entertainment (games). Many computers have sound capabilities built in, while others require additional expansion cards to provide for audio capability.
  • If you are interested in watching DVDs or playing games with surround sound, or even getting a rich audio experience from CDs and MP3s, you will want a sound card that is up to snuff. However, sound cards are fairly easy to upgrade.
    (Sound card is only as good as the speakers.)
    Search Amazon.com for sound card
Software
  • Computer software, or just software, is the collection of computer programs and related data that provide the instructions telling a computer what to do. We can also say software refers to one or more computer programs and data held in the storage of the computer for some purposes. Program software performs the function of the program it implements, either by directly providing instructions to the computer hardware or by serving as input to another piece of software. The term was coined to contrast to the old term hardware (meaning physical devices).
  • Most often software bundles come at an extra cost, such as those for managing finances, editing images and even doing word processing.
  • Every hardware has a software installer to run the program.  See example: Search Amazon.com for software
