This description explores the impact of the computer revolution on our lives. It looks at how computers have changed the way we work, communicate, and access information. It examines the development of the computer from its early days to its current state, and the implications of this technology for our future.
A computer is a machine that can be programmed to automatically carry out sequences of arithmetic or logical operations (computation). Modern digital electronic computers can perform generic sets of operations known as programs, which enable computers to perform a wide range of tasks. The term computer system may refer to a nominally complete computer that includes the hardware, operating system, software, and peripheral equipment needed and used for full operation, or to a group of computers that are linked and function together, such as a computer network or computer cluster.
