article on computer the wonderful machine about 150 to 180 words

Answer 1

computer is a device that can be instructedto carry out an arbitrary set of arithmetic or logical operations automatically. The ability of computers to follow generalized sequences of operations, called programs, enable them to perform a wide range of tasks.

Such computers are used as control systemsfor a very wide variety of industrial and consumer devices. This includes simple special purpose devices like microwave ovensand remote controls, factory devices such as industrial robots and computer assisted design, but also in general purpose devices like personal computers and mobile devicessuch as smartphones. The Internet is run on computers and it connects millions of other computers.

Since ancient times, simple manual devices like the abacus aided people in doing calculations. Early in the Industrial Revolution, some mechanical devices were built to automate long tedious tasks, such as guiding patterns for looms. More sophisticated electrical machines did specialized analogcalculations in the early 20th century. The first digital electronic calculating machines were developed during World War II. The speed, power, and versatility of computers has increased continuously and dramatically since then.
