Random Access Memory (RAM)

• Random Access Memory (RAM) -It is also known as the physical memory of the computer. Fast-access memory that is cleared when the computer is powered-down. RAM attaches directly to the motherboard, and is used to store programs that are currently running.

• Firmware is loaded from the Read only memory ROM run from the Basic Input-Output System (BIOS) or in newer systems Extensible Firmware Interface (EFI) compliant.

  As its name suggests, firmware is somewhere between hardware and software. Like software, it is a computer program which is executed by a microprocessor or a microcontroller . But it is also tightly linked to a piece of hardware, and has little meaning outside of it.

Computer fan

• Computer fan - Used to lower the temperature of the computer; a fan is almost always attached to the CPU, and the computer case will generally have several fans to maintain a constant airflow. Liquid cooling can also be used to cool a computer, though it focuses more on individual parts rather than the overall temperature inside the chassis.

Central processing unit (CPU)

• Central processing unit (CPU) - Performs most of the calculations which enable a computer to function, sometimes referred to as the "brain" of the computer.

Motherboard

• Motherboard - It is the "body" or mainframe of the computer, through which all other components interface.

Video Graphics Card for your PC

Purchasing a new video card for your computer can be a tough decision. There are approximately 60 different models of video cards available for purchase in America (PC World Magazine, 08). Most of which feature graphics chip technology from one of the two large graphic companies: ATI Technologies and NVidia Corp. However, if you can answer a couple questions about how you plan to use the card and what computer system you have, you can make the process much simpler and choose the best video card for your needs and budget.

Whether you are considering an upgrade to your current system, or you want your new system to be able to run the latest games, here are some things you should know before buying a video card.

Did You Update the Drivers?
If you’re thinking of replacing your video card because you’re having problems running a certain game or whatever, make sure you have the latest version of the drivers for your current graphics card. You will find the latest drivers for your card available for download from the manufacturer’s Web site.

Chipsets

For the purpose of gaming or high-end graphic work… two developers of 3D graphics card chipsets have come to dominate the market: NVidia and ATI Radeon. While there are many video card manufacturers, most of them build their cards around chipsets designed and supported by one of these two companies. Certain games and heavy graphic applications will run a little better on one chipset than another – something you might want to consider before deciding which way to go.
