The document provides a brief history of computers from 3000 BC to 1995 AD. It describes early calculating devices like the abacus and lists important developments like Charles Babbage originating the concept of a programmable computer in 1822. It then outlines the creation of early general purpose computers in the 1940s and key advancements that led to the development of personal computers in the 1970s and 1980s, including the Altair 8800 and the Apple I. The document ends with questions about personal experiences with computers.
