Computer Classification by Memory Size

Computers are categorized based on memory size into:
- Microcomputers
- Mini computers
- Mainframe computers
- Supercomputers

Microcomputer

Microcomputers have a low processing speed and a limited storage capacity.
The central processing unit (CPU) is an 8-bit microprocessor.
Personal computers (PCs), such as IBM PC and PC-AT, are examples.

Mini Computer

Mini computers support multiple users simultaneously.
They have a larger storage capacity compared to microcomputers.
They operate at a faster speed than microcomputers.
Mini computers are used in local area networks (LANs) and for processing large amounts of data in organizations.

Mainframe Computer

Mainframe computers are referred to as 32-bit computers.
They have a high processing speed.
They have a large storage capacity.
They handle workloads of many users simultaneously.
Mainframes are frequently utilized in centralized databases and as controlling nodes in wide area networks (WANs).
Examples include DEC, ICL, and IBM 3000 series.

Supercomputer

Supercomputers are the fastest and most costly type.
They have a high processing speed due to multiprocessing techniques.
They are constructed by interconnecting hundreds of microprocessors.
Common applications include weather forecasting, biomedical research, remote sensing, and aircraft design.
Examples of supercomputers are CRAY YMP, CRAY2, NEC SX3, CRAY XMP, and PARAM.
