Like many machines that people use on a daily basis, the computer is one particular machine that is used so often that the way it works is of little importance. However, it is useful to learn what a computer is made of so that folks can identify the potential roots of errors or malfunctions. Each computer has three essential parts-- the CPU, monitor, and keyboard; the mouse (or touch pad for laptops) is considered a fourth component.

CPU stands for central processing unit, which is really just a small chip that works as the "brain" of any computer. Like how the human brain controls certain central nervous functions, the CPU takes care of the computer's various processes. It is positioned inside the computer's system board, in which all the various other parts are connected to it. If the CPU is the brain, then the system board is the computer's spinal column; all essential parts are linked to the system board, which the CPU deals with.
Subsequently, the CPU requires a mechanism in place to prevent it from getting too hot. That's because every time the CPU is functioning, it slowly gets hotter and needs a fan to cool ...
... it down to keep the heat from ruining it. This is made possible by the power connector close to the edge of the system board; for laptops, there is likewise a battery.

A number of system boards include a RAID system regulated through a DELL TD977 PERC 4e/DC Dual Channel U320 LVD SCSI RAID Controller BBU. RAID stands for redundant array of independent disks, which is a series of several hard disks that can store replicas of identical information or data simultaneously. This makes data recovery processes less complicated to execute in case the computer fails and is in need of reformatting.

In addition to these ports linking to permanently installed hard disks, there are additionally slots on the system board for detachable disks. The DELL YU413 Dell Latitude E6500 System board, for instance, also contains drives for removable disks such as USB thumb drives. There are also ports on the system board for a CD, DVD, or both.

Meanwhile, some system boards incorporate hot swap trays. The DELL X2689 74GB SCSI 80-PIN WITH 1 HOT SWAP TRAY, for instance, is a device that can fit more than one sort of disk. Hot swap trays are compatible with the big PCs. If you want additional information, check out ComputerHope.com.
