Types of Computers
- Computers can be separated into two main types:
- Computers for individuals are normally designed for one user at a time.
- Computers for organizations are designed to be used by many people at the same time
Computers for individuals
- Personal computers (PCs)are generally either Mac (Apple’s Macintosh) systems or IBM-compatible systems.
- Desktop computers,designed for home or office desk use, now include all-in-one computers that combine the system unit and the monitor.
Computers for individuals
- Notebook computers are small enough for easy computer mobility.
- Tablet PCs can be used to input data with a keyboard or mouse, and the user can write on the monitor with a special pen or stylus.(Tablet PC is a small laptop computer, equipped with a rotatable touch screen as an additional input device.
- Net books are small, inexpensive notebooks designed primarily for wireless Web browsing and e-mail.
- Smartphones combine the capabilities of handheld computers, such as PDAs, and mobile phones.
Computers for organizations
- Servers enable users connected to a computer network to have access to the network’s programs, hardware, and data.
- Clients include the user computers connected to the network.
- A client/server network includes the use of client computers with centralized servers.
- Minicomputers or mid range servers are designed to meet the needs of smaller companies or businesses.
- Minicomputers enable dozens, hundreds, or even thousands of users to connect to the mat the same time Types.
- Mainframes carry out very large processing jobs to meet the needs of large companies or agencies of the government (ex. Airline reservation).
- Mainframes are designed to be used by hundreds of thousands of users at the same time.
- Supercomputers are ultra fast computers that process huge amounts of scientific data, they are able to perform extremely high-speed processing and show underlying patterns that have been discovering the data.
