What is Microcomputer

A microcomputer is a small computer with a microprocessor that a single user can operate at a time.

This type of computer is typically used in homes and offices. The microcomputer can perform simple calculations, word processing and data entry work.

This computer has a central processing unit (CPU) which acts as a bridge to communicate between hardware and software.

The CPU can have multiple processors in it that can perform multiple parallel tasks at a time.

It is called a “micro” computer because it is small in size and has less processing power as compared to a mainframe computer and a supercomputer.

It is easy to carry a microcomputer.

Some types of microcomputers are tablets, desktop computers, laptops, and smartphones.

Uses of Microcomputers and Examples of Microcomputers

The initial work on microcomputers started in the 1960-70s.

As you know microcomputers cannot work without a microprocessor. The first microprocessor named 4004 was created by Intel in 1968. This microprocessor can process 1 bit at a time. Then in 1971, a 4-bit processor was introduced which was named 4008.

In 1972 the 8-bit processor came and was used by the first microcomputer (Altair 8800).

Apple Company invented its first microcomputer in 1976.

In 1981, IBM introduced its first personal computer (PC). Note that a microcomputer is also known as a PC.

In old days microcomputers come with a command line interface but after a few years, microcomputers came with GUI (Graphical user interface).

MS-DOS was the first command line operating system that was used to operate microcomputers. Later Windows OS was invented by Microsoft that came with GUI.

The first MAC computer was invented by Apple Company that had a built-in GUI in it.

In later years in 2001, iPod was released by Apple Company which is also a type of small computer (Microcomputer). Then in 2007, iPhone was released which is also a type of microcomputer.
