Study Notes
Classification of Computers by Size
- Supercomputers: the fastest, most powerful, and expensive type of computer, designed to process vast amounts of data in a short time with high productivity.
- Mainframe computers: multi-programming, high-performance, multi-user computers that can handle the workload of over 100 users at a time, with enormous storage capacity and high-speed data processing.
- Minicomputers: multi-user, general-purpose computers that are slower than mainframes, but capable of performing similar tasks.
Classification of Computers by Purpose
- General Purpose Computers: designed to perform a variety of common tasks, adaptable, but less effective and slower.
- Special Purpose Computers: designed to perform a single specific task, with programs permanently stored in internal memory, making them less expensive.
Classification of Computers by Type
- Analog Computers: measure continuously varying aspects of physical quantities such as electrical current, voltages, hydraulic pressure, and other electrical and mechanical properties.
- Digital Computers: use digits to represent letters, numbers, and special symbols, with on-off (ON-OFF) inputs, and create ON-OFF signals.
- Hybrid Computers: combine digital and analog systems, handling both digital and analog inputs, used in medical science, controlling industrial processes, and scientific applications.
Components of a Computer System
- Hardware: physical components of a computer system.
- Software: intangible components of a computer system, such as programs and operating systems.
- Humanware: the people who use, operate, and manage the computer system.
Microcomputers
- Low-cost digital computers with a single microprocessor, storage unit, and input/output device.
- Designed for individual use only.
- Examples include desktop, laptop, tablet, workstation, PDA, and palmtop computers.
