It encompasses both the study of theoretical algorithms and the practical problems involved in implementing them through computer hardware and software. Computer network, two or more computers that are connected with one another for the purpose of communicating data electronically. Definition: A minicomputer is also known as mini. A minicomputer is a computer which has all the features of a large size computer, but its size is smaller than those.A minicomputer lies between the mainframe and the microcomputer because its size is smaller than the former one and larger than the latter one. Computer literacy definition, basic, nontechnical knowledge about computers and how to use them; familiarity and experience with computers, software, and computer systems. Computer definition: A computer is an electronic machine that can store and deal with large amounts of... | Meaning, pronunciation, translations and examples WANs connect computers over … Computer science is the study of both computer hardware and software design. The two principal characteristics of a computer are: It responds to a specific set of instructions in a well-defined manner and it can execute a prerecorded list of instructions (a program).. Modern Computers Defined Computer: Technically, a computer is a programmable machine. Today, however, the term is most often used to refer to the desktop and laptop computers that most people use. A computer is a programmable device that stores, retrieves, and processes data.The term "computer" was originally given to humans (human computers) who performed numerical calculations using mechanical calculators, such as the abacus and slide rule.The term was later given to a mechanical device as they began replacing the human computers. LANs connect computers in a limited area. Personal computer definition is - a general-purpose computer equipped with a microprocessor and designed to run especially commercial software (such as a … Two basic network types are local-area networks (LANs) and wide-area networks (WANs). See more. This means it can execute a programmed list of instructions and respond to new instructions that it is given. They are primarily used by large organizations for mission-critical applications requiring high volumes of data processing. Mainframes are a type of computer that generally are known for their large size, amount of storage, processing power and high level of reliability. See computer revolution. It is a class of small computers that was introduced into the world in the mid-1960s. Following is a brief summary of the generations of computers based on their hardware and software architecture. Cpu definition is - the component of a computer system that performs the basic operations (such as processing data) of the system, that exchanges data with the system's memory or peripherals, and that manages the system's other components —called also processor.
