In 1897, it was known as the 'calculating machine'. It was derived from the Latin word 'computare', which meant 'to calculate'. The term 'Computer' was first introduced in 1640 and referred to as 'one who calculates'. Whatever is given to the computer as input is called 'data', while the output received after processing is called 'information'. In simple terms, a computer is a programmable electronic machine used to store, retrieve, and process data.Īccording to the definition, " A computer is a programmable electronic device that takes data, perform instructed arithmetic and logical operations, and gives the output." However, modern computers are not just a calculating device anymore. The straightforward meaning of a computer is a machine that can calculate. Let us start with defining the computer first: What is a Computer? As they are such an essential part of our lives, we must know about the basic computer introduction. Nowadays, computers can be seen in banks, shops, schools, hospitals, railways, and many more places, including our home. That means computers are present in almost every field, making our day-to-day tasks easier and faster. In the modern era, computers are an essential part of our everyday existence.
