Computer the best machine that helps to solve the longest calculations and has automated the most tire some processes is build up of the basic components such as a central processing unit, disk drives, keyboard, monitor, mother board and other such important components that functions parallel with each other. The functions of each of these basic components are different and are very important for proper functioning of the computer that ultimately proves useful to us. Computer system consists of input and output devices, however he basic components of a computer system are:Central Processing Unit – Concisely known and understood as the CPU, this unit is the brain of any computer system. A computer system cannot exist without the CPU and this is because it contains all the sub basic units such as the arithmetic unit and others that performs all the mathematical and other operations.Motherboard – This is the part of the computer to which all the hardware is connected to. It consists of processors and other sub processors that perform very important memory related operations. There are various kinds of motherboard available depending on the configuration of computer system required.Random Access Memory – This part of the computer system also widely known as RAM is connected to the motherboard. As quite obvious from the name itself, RAM stores the data temporarily and the data stored also can be accessed from RAM. Data from here can be moved to a permanent storage such as compact disks and hard disks.Monitor – This is also considered as the most versatile and important part of a computer system and is one of the output devices. This is the part where user can see and input the desired results and data to the computer. The various operations that are desired and the result of any mathematical calculation can be viewed on the monitor. In short, this is the user interface through which the user and the computer can communicate to each other.Keyboard – Keyboard is an input device component through which a user can input the data and this data can be of any type depending on the type of input. The use of keyboard can be varied depending upon the type of use. For example it can also be used as a gaming device while playing games etc.
Hard Drive – The data that was stored temporarily in the RAM can be moved and stored in the hard disk drives. The size of the hard disk drives can be varied depending upon the use and the requirement of the user.Disk Drives – These can be considered to be an optional component of a computer system. If a user needs to read a data from a floppy drive, USB drive or a compact disk drive then disk drives can be installed, again depending upon the use and requirement of the user.
The above mentioned components when assembled properly forms a computer system that can be used for various purposes such as basic office record keeping, surfing internet, communication, automation of works etc.
