What is a Mini Computer? – Explained in Simple English

A mini computer is a type of computer that is medium in size—not too big and not too small. It is larger than a microcomputer but smaller than a mainframe computer.

In simple words, a mini computer is a mid-sized computer that includes all the basic features of a regular computer. These computers are designed to support multiple users at the same time, making them multi-user systems.

Mini computers are more powerful than microcomputers but not as powerful as mainframe or supercomputers. They are also multiprocessing systems, meaning they can use two or more processors to perform tasks efficiently. Because of this, mini computers are capable of handling heavy workloads and complex tasks with ease.

Mini computers are also multi-tasking machines, allowing users to perform many tasks at once. They are widely used in business environments for managing transactions, handling files, and managing databases.

The concept of mini computers dates back to the 1960s when IBM (International Business Machines) developed them. The first mini computer in the world was PDP-8, introduced by DEC (Digital Equipment Corporation) in 1964.

Today, mini computers are used in large companies for tasks like billing, accounting, and inventory management. They are also known as mid-range computers because their cost is higher than personal computers (PCs).

Examples of Mini Computers:

• Apple iPad

• Samsung Tab

• Dell Inspiron 1012

• Apple iPhone
