Don't Allow Your Computer To Intimidate You

When you know your computer parts and how they work, it will lose its power to intimidate you. Pay attention to these 6 major parts namely: processor speed (CPU), VRAM, RAM, hard drive, optical drives and USB port. 
  • The processor speed is measured in MHz and GHz, typically from I.0 MHz to 2.66 GHZ. For example, a 1 MHz CPU can accomplish one million “central processing units” in one second, meaning it can do a task or calculation at that speed. The higher the CPU the higher is the processing speed. Though a faster CPU will not necessarily load your web pages any quicker. The loading speed is limited by the speed of your connection – telephone line or broadband.
    • The VRAM is the memory set aside to store and access graphic and image data. The higher the VRAM the faster the computer can display images. For normal word processing and Internet browsing 256 MB to 512 MB is adequate, for heavy graphics and games use 512 MB and higher.
    • The RAM is the computer memory, and dictates how much the laptop or desktop can do at once. It also determines the size of the task it can perform in terms of file size. Since the RAM determines what you can do on your computer, if you have to choose between a high-speed processor and a high-capacity RAM, choose a high-capacity RAM. Typical range of RAM is 256 MB to 1 GB.
    • The hard drive is the physical hard disk of the computer. It is where applications and data are stored. More capacity is better, especially when you use music, digital photographs and movies files. Typical range of hard drive is 60 GB to 320 GB.
    There are different types of optical drives, among them are:
    • CD-ROM: it reads CD but not DVD.
    • CD-RW: it reads and writes on CD but not on DVD. It is useful for data backups and archiving of music, digital photographs and videos.
    • DVD-ROM: it reads CD and DVD.
    • DVD-RW: it reads and writes on CD and DVD. Check if your DVD writer is compatible with your computer as they come in different standards.
    • The USB port on your computer connects you to the broadband via a USB cable. Other peripherals such as printers, scanners and external hard drives are connected to the computer through the USB port. An upgrade in the USB cable called USB2 allows faster data transfer to external hard drives, CD or DVD drives, but it is more expensive.
    Now that you know the parts of your computer and how they work, you can talk about computers with confidence, and the next time you go out to buy a new computer, you will certainly ask more questions and get a better laptop or desktop for your money.
