Components of a Computer System
Saying that computers have revolutionized our lives would be an understatement. These machines have completely changed the way we perform all daily tasks. In order to further maximize their potential, we must understand the core components of a computer system in detail – input unit, output unit, CPU.
Meaning of Computers
Computerized Accounting System
Computers, in simple words, are machines that perform a set of functions according to their users’ directions. Going by this definition, several electronic devices, from laptops to calculators, are computers.
A computer comprises of some basic elements. These include hardware, software, programmes, data and connectivity. No computer can function in the absence of these elements. Apart from these elements, a computer system comprises of three basic components. These components are responsible for making computers actually function. Let’s take a look at them in detail.
Components of a Computer System
Every computer system has the following three basic components:
Input unit
Central processing unit
Output unit
Components of a Computer System: Input Unit, Output Unit, CPU
While there are other components as well, these three are primarily responsible for making a computer function. They must work in complete synergy because that will ensure smooth overall functioning. Hence, we can even call them building blocks of a computer system.
Input Unit
These components help users enter data and commands into a computer system. Data can be in the form of numbers, words, actions, commands, etc. The main function of input devices is to direct commands and data into computers. Computers then use their CPU to process this data and produce output.
For example, a laptop’s keyboard is an input unit that enters numbers and characters. Similarly, even a mouse can be an input unit for entering directions and commands. Other examples include barcode readers, Magnetic Ink Character Readers (MICR), Optical Character Readers (OCR), etc.
Another example of input devices is touch-screens. Users can simply touch these screens without using any other device to enter commands. From smartphones to ATM machines, these input devices are becoming very popular these days.
