Basic Operating system of a computer

The computer is constituted of both hardware and software. Let’s get to know more about each.

Hardware

The external part of the computer is called hardware. Or in other words, it can be called the part of the computer which can be touched or seen by anyone who wishes to use the computer. The hardware is something that is physically connected to the computer.

Software

Software is otherwise called a set of instructions and programs. Software is essential for the computer to run and the program can move on smoothly only with the help of software. The software provides the capability to the user to operate on the computer smoothly and effectively.

User

The person who is operating the computer is called the user. The computer needs to be operated by someone. The computer needs to be manually turned on and off should run the programs. the users’ instructions play a vital part in the functioning of the computer.

Data

The given instructions and programs in the computer are stored in the condition of numerals. The data can be easily read and constituted by the computer.

Input

To process and operate the computer and any software associated with it, the user ought to give instructions. Those instructions are otherwise termed as inputs. The input data can be stored in an organized way one after the other by the computer.

Storage

It functions to store and save data safely. The storage unit can permanently store any data. the storage unit performance different functions which include the data collection and storage of the data and instructions before processing and after processing. The immediate results of the processing are also stored in the storage unit.

Processing

Many of the operations are mandated to accomplish any mission. the operations are arithmetic and logical. The arithmetic and logical operations in a system are called processing. CPU is the major processing unit in the computer. The CPU processes the data from the storage unit and the immediate results are sent back to the storage unit.

Output

The generated results are called outputs. When the instructions are given, the input to the computer transforms into the results and it is duly called the output. The outputs are stored inside the storage unit and then it is shown to the desired us. The outputs are given in readable format.

Control

The controlling of the input-output and processing unit is done by the control unit. The control unit is pivotal to the processing of a computer. The overall take caring of all the operations in the computer is done by the control unit.
