What is Computer?

A computer is an electronic system that uses instructions to store, retrieve, and process data by using hardware and software.

It uses computer programming to perform arithmetical or logical operations sequences.

The computer contains particularly arithmetic and logical units i.e. ALU.

Computers can be technology-based ie. It can be digital, analog, or hybrid.

There are also several other Super Computers, Personal Computers, Desktops, Laptops, etc.

The computer is often known to be a computing machine since, without software, it cannot do anything.

It takes user raw data as an input process and produces user output.

In simple words, we can say that the digital computer is an electronic device along with its components i.e. hardware and software (just like apps on mobile).

It makes our life easier by processing raw data output in any form given to it, into meaningful data as desired by the user.

There is a lot of software and hardware available in the market as per the user requirements.

Classification of the Computer on the basis of Generations:-

The Generations of computers are defined on the basis of major technological changes:-

First Generation (1940-1956) – uses vacuum tubes, ENIAC was the first computer of this generation.

Second Generation (1956-1963) – uses transistors rather than vacuum tubes.

Third Generation (1964-1971)- ICs (integrated circuits) was used in place of transistors which reduced the size of computers.

Fourth Generation (1972-2010) – uses microprocessors and ICs.

Fifth Generation (2010- present) – the fifth generation of computers uses AI (artificial intelligence) and some best examples of these are Siri on iPhone, and Cortana on Windows 8, and 10.

What does CPU stand for in Computer?

Do you know what is CPU in Computer? A CPU in a computer is one of the important components of the computer system. CPU is sometimes called the computer brain.

CPU in Computer stands for:-

C – Central

P – Processing

U – Unit

A special region called the CPU (Central Processing Unit) socket is the area where the CPU is mounted within the motherboard to handle other device inputs and outputs.

It performs all of the basic arithmetical and logical operating operations and communicates the computer’s commands and programs.

The term CPU conventionally refers to a processor that includes the control unit and the logical arithmetic unit.

What is the full form of ALU?

A – Arithmetic

L – Logic

U – Unit is the complete full form of ALU.

Arithmetic logic unit abbreviation will be – The portion of a machine that performs all arithmetic computations.

The ALU is divided into two units in processors, an arithmetic unit (AU) and a logic unit (LU).

It represents the fundamental building block of a computer’s central processing unit (CPU). Modern CPUs contain highly potent, complex ALUs.

What is the full form of a LAPTOP?

A laptop or a laptop computer is, in simple words, a small portable device.

The full form of the laptop is:-

L – Lightweight

A – Analytical

P – Platform

T – with Total

O – Optimized

P – Power

  1. The author of this post has undoubtedly done a great job by shaping this article on such an uncommon yet untouched topic. There are not many posts to be seen on this topic and hence whenever I came across this one, I didn’t think twice before reading it. The language of this post is extremely clear and easy to understand and this is possibly the USP of this post.
