It is a programmable electronic device that accepts raw data as input.

It is designed to execute applications and provides a variety of solutions through integrated hardware and software components.

The term "computer" is derived from the Latin word "computare" which means to.

What is the first computer?

Who invent the first computer in 1837?

Charles Babbage is called.

Basic Parts of the Computer (all capitalized)

It executes instructions from software and hardware.

It is the primary memory for data transfer between the CPU and storage.

It is the part that connects all other parts or components of a computer.

It permanently stores the data, e.g., hard drive.

It allows you to communicate with the computer or to input data, e.g., a keyboard.

It enables you to see the output, e.g., monitor.

Computers are divided into different types based on different criteria. Based on the size, a computer can be divided into five types:(all capitalized)

It is a single-user computer which has less speed and storage capacity than the other types.

It uses a microprocessor as a CPU.

They are also known as "Midrange Computers."

They are not designed for a single. They are multi-user computers designed to support multiple users simultaneously.

They are generally used by small businesses and firms

It is also a multi-user computer capable of supporting thousands of users simultaneously.

They are used by large firms and government organizations to run their business operations as they can store and process large amounts of data.

They are the fastest and most expensive computers among all types of computers.

They have huge storage capacities and computing speeds and thus can perform millions of instructions per second.

It is a single-user computer. Although it is like a personal computer, it has a more powerful microprocessor and a higher-quality monitor than a microcomputer.
