UNIT – 2,1.The four major components of the motherboard are:A.BIOS;The BIOS (basic input / output system) is basically the "software" the computer uses, it is most basic operations (accessing memory, disks, processors, etc.). This "software" is built into the computer's motherboard, so do not worry about losing it if your hard drive crashes.Most BIOS setups allow you to configure hard drive parameters, set the time, type of floppy disk drives, memory timing and so on. It is an area that's best left alone unless you are an experienced computer user.(Note that these are NOT Windows settings, these are the "core" settings for your computer. You normally can get at them by pressing the DEL key a few seconds after you turn your computer on (this can vary from machine to machine though).B.CMOS Memory:CMOS (complementary metal oxide semiconductor) is a low powered memory chip. Even when the computer is turned off, CMOS is running. The CMOS chip has its own battery, that will last 7 to 10 years. Once the battery dies all configuration information will be lost and will have to be re-entered.C.RAM Slots:RAM (Random Access Memory) and is pronounced like the male sheep. RAM is made up of small memory chips that form a memory module. These modules are installed in the RAM slots on the motherboard of your computer. Every time you open a program, it gets loaded from the hard drive into the RAM. The more RAM your computer has, the more data can be loaded from the hard drive into the RAM, which can effectively speed up your computer. In fact, adding RAM can be more beneficial to your computer's performance than upgrading the CPU.To check how much RAM a Windows computer has, open the Control Panel. This can be done by right-clicking "My Computer" and selecting "Properties”.D. Parallel Port:This interface is found on the back of older PCs and is used for connecting external devices such as printers or scanners. It uses a 25-pin connector and is rather large compared to most new interfaces. It is sometimes also referred to as a printer port, because the printer is the device most commonly attached to the parallel port. The latest parallel port is called the Enhanced Parallel Port (EPP). This standard supports bi-directional communication and can transfer data up to ten times faster than the original 25-pin connector port. Since the parallel port is a rather dated technology, do not be surprised to see USB or Firewire interfaces completely replace parallel ports in the future.1.Describe the CPU and provide a picture;CPU (Central Processing Unit), this is the pretty much the brain of your computer. It processes everything from basic instructions to complex functions. Any time something needs to be computed, it gets sent to the CPU. Every day it is compute this, compute that (you would think the CPU would need a break after awhile). But no, it just keeps on processing. The CPU can also be referred to simply as the "processor."2.Describe expansion slots and...
