A to Z Computer Vocabulary Word List

A computer is an electronic device that processes data according to a set of instructions, called a program. It performs various tasks by following programmed instructions. Computers can handle different types of data, such as text, numbers, images and sounds, and perform complex calculations at high speed. At its core, a computer takes input, processes it, stores it, and then produces output. Input can come from a variety of sources, such as keyboard, mouse, microphone, or other devices. Once input is received, the computer’s central processing unit (CPU) processes the information by performing calculations or logical operations. Processed data may be stored in the computer’s memory, including short-term memory (RAM) and long-term storage (hard drives or solid-state drives).

Computers run software applications to accomplish specific tasks. For example, a word processor helps you write documents, a web browser allows you to access the Internet, and a game can provide entertainment. Software can range from simple programs to complex systems, such as operating systems that manage all of a computer’s hardware and software resources. Modern computers come in a variety of forms, from large desktop machines to portable laptops, tablets, and even smartphones. They can be used for many purposes including personal, educational, business and scientific applications. Computers are connected to networks, such as the Internet, which enable them to communicate with other computers and share resources and information.

The history of computers begins with the earliest mechanical devices and has evolved through various stages, from large and room-sized machines to today’s compact and powerful devices. Advances in technology have made computers faster, more efficient, and more accessible to people around the world. A computer is a versatile, powerful device that can process and store data, run applications, and connect to networks, making it an essential part of modern life across a variety of activities and industries.
