What is the Computer?
A computer is just only a dependent machine that takes a first-time input with the help of human being, then converts all these inputs in the binary form with the help of translators to understand them, and after it processes that input with the help of a microprocessor to give the meaningful result according to your input data.
These three fundamental processes of a Computer System or any electronic device. we can perform various types of work through these devices without any mistakes. The computer gives us a lot of benefits to complete our task. These benefits are –
- Work Accuracy
- Speed Capacity
- versatility
- Reliability
- Storage Capacity
Define & Extract the benefits of Computer System to Human Being.
1-: Work Accuracy
Computer can perform all type of work with 100% accuracy, if we give input correctly with correct expectation. Computer System has also a brain, that is also known as C.P.U. It executes all of the instruction with the help of C.U(Control Unit), M.U(Memory Unit), A.L.U(Arithmetic logical Unit). These are the interconnected parts of the Central Processing Unit(C.P.U).
2-: Speed Capacity
A Computer can perform several huge tasks such as mathematical calculation, storing the data, or transferring the data at the least time. Generally, Computer processes the data at very high speed than the Human being. The speed of any electronic device is directly referred to as the brain of the Computer- C.P.U. In other words, C.P.U is the main component to enhance the speed of the Computer System to process the instruction quickly.
3-: Versatility
The computer can perform fully-loaded tasks without weary because the Computer is a machine that is built from wires and IC Chips rather than bones, muscles, and blood. A computer can perform a lot of work continuously with the help of an AC or DC power supply.
4-: Reliability
A Computer can perform all of the given tasks in a well and organized manner. It is a special type of quality that a computer has kept. This reliability has to be done with the help of an OS(Operating System). An OS is a type of software that manages and handles all software and hardware devices of a Computer System.
5-: Storage Capacity
A computer have contains various types of memory to store temporary or permanent data. we can store all types of documents in the computer system. It is a very essential part of any electronic device because data is a must to us till the expiration time of data comes.
Functions of Computer System
In the Computer System, mainly three type of functions are used to create, process and store the user data into computer system. These functions are defined below –
- Input Functions
- Processing Functions
- Output Functions
Input Functions
In the Computer System, the Input function is a basic function for every electronic device, Input functions are used to take the input from the user. This function helps us to enter the data or instructions in the computer system to process the instruction and to take the output from the computer system. Input functions provide us various input devices to input the data into the Computer System. These devices named such as – Mouse, Keyboard, Scanner, Light pen, e.t.c.
Processing Functions
In the Computer System, the processing function is a second basic function for every electronic device, Processing functions are used to process the given data by the user. This function helps us to execute the instructions one by one with the help of translators and the main parts of C.P.U. Processing functions provide us various processing devices to process the data into the Computer System. These devices named such as- A.L.U(Arithmetic Logical Unit), C.U(Control Unit), M.U(Memory Unit), e.t.c.
Output Functions
In the Computer System, the output function is a third basic function for every electronic device, Output functions are used to display the processed data to the user. This function helps us to show the results. Output functions provide us various output devices to represent the data for the User. These devices named such as – a Monitor, Printer, Speaker, e.t.c.
