All PCs are made of up many interlinking computer components. Understanding the role of these components can help one discover where the computer problems are occurring. Even though many advances have been made in the home PC, the components of computer have remained the same.
Every computer is built around what is called the main board that acts like the central station. From here connections to other subunits and are closely interlinked. Components of computer main board include sockets and other subunits, for connections of cables or card slots.
The central processing unit (CPU) is the key component that performs all complex calculations required to run the computer. CPU is complex unit which has supporting circuits and subunits all bundled up into one single unit. The CPU is measured in GHz and the higher the GHz the faster the computer.
Other computer hardware components included RAM or memory. Memory is useful for storage and contains varied instructions for the CPU functions. All computers access RAM memory to function but this memory is never saved. RAM is the original memory of all computers and when the device is switched on; all the pertinent applications and files are opened using this memory. All computer hardware components that tend to heat up have some type of cooling system to prevent damage.
The majority of computer internal components include at least one disc drive, which may vary from a CD, DVD, floppy disc or hard disc drive. Memory of computers is measured in gigabytes (GB) and the higher the GB, the greater is the available memory. Memory chips easily fit into slots on the main board and one can even add more memory if desired. When computers start to slow down, it means that your hard drive capacity is full and you may need to add more memory.
Other computer internal components include a variety of interface cards that allow for external device(s) to input or read data from the computer. Such interface cards include phone lines, video, audio, network or modem cards. Modem cards allow many other drives to be used on a single computer. Today, fancy routers are available and modems are fast becoming obsolete.
Power supply is a definite requirement for all PC. All computers have capability of converting power from the wall socket into usable efficiency power that is suitable and safer for the computer. Computers tend to use direct current and the source is usually found inside the deep compartment.
The reason why it is important to know about computer parts is that one can make PCs that are better, faster and a lot cheaper than what is available in retail stores. Customization allows the consumer to build a great PC by buying only the relevant computer components.
