A computer is an electronic device that can process, transmit, and save data. Overtime computers have been used for construction and other sources and have had many technological advances. Computers can also obtain responses. The first electronic computers were created during the mid 20th century and were the size of a very large room. Their electrical consumption of one of these computers was equal to that of several hundred modern day computers. Integrated circuits are used in today's computers and computers cannot "think" themselves. In order for a computer to perform a task, a computer has to be programmed by the user to do so.
