computer software
Computer software can be categorized as either system software or application software. System software includes operating systems, utilities, and device drivers that control hardware and allow application software to function. Application software includes programs for specific tasks like word processing, spreadsheets, and databases. There are different types of application software such as proprietary, in-house, off-the-shelf, and customized packages, as well as different forms like packaged software, custom software, web applications, and open source software. System software programs operate at a low level to control the computer hardware and enhance processing capabilities.
Types of computer
There are four main types of computers: microcomputers, minicomputers, mainframes, and supercomputers. Microcomputers are small, portable, and low-cost devices used in homes and offices. Minicomputers are medium-sized machines that support multiple users at lower costs than mainframes. Mainframes are large, room-sized computers that serve many distributed users and servers. Supercomputers are the fastest and most expensive computers, used for advanced research applications that require parallel processing.
