Parts of the computer Submitted by: Ralph Sialtel V. Simbillo
Video Card (GPU - Graphics Processing Unit) The video card sends the visual output produced by a program on to the monitor, which displays that on the screen. For gamers and others who use very high end graphics or special video work regularly, the GPU will be the most expensive part of the computer. These cards also run very hot, and most contain a fan on the side.
Memory (RAM) The memory holds "short term" information for the processor to use. This may be a program, or a set of data. The processor is able to retrieve information from the RAM at very high speeds. When the processor needs information that isn't in the RAM, it has to read the information from the hard drive, which is much slower.
Processor (CPU) The CPU, or the Central Processing Unit, is the brain of the computer and the most important chip in the computer. When you run a program, the CPU performs the calculations and carries out the commands. Modern processors contain millions of transistors (miniature electronic switches) that are etched onto a small silicon square called a die. The die is about the width of a thumb.
Motherboard The motherboard is the main circuit board of the computer. It holds the CPU, RAM modules and most of the circuitry. All adapter cards plug into your motherboard. The motherboard defines how much RAM, adapter cards, and the type of CPU the computer is going to have.
