Study Notes
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.
