<human>:  What is the history of the computer?
<bot>: The history of the computer dates back to the mid-20th century, when the first electronic computers were developed. Prior to this, people used mechanical calculators and early mechanical computers, such as the Zuse Z3 and the ENIAC, starting in the 1930s. The first stored-program computer, the Manchester Baby, was developed in 1948. The transistor, invented in 1947, was a major development in computer technology and allowed for the greater processing power and smaller physical size of today’s computers. Over the next 30-plus years, computer technology advanced rapidly, with increasingly powerful and versatile computers being developed. Today, computers are widely used in all facets of life, for tasks such as business, entertainment and communication.
