Then what should we do if we want to develop more functions of the computer?Study hard.
Learn as much knowledge as we can.
Prepare to become great scientists! Now people can use computers to deal with information and communicate with each other around the world by __________ . But the development of computers has a long history. In 1642 the first computer only worked as a ________________ . In 1822, an Analytical Machine was invented. In 1936 a machine was built. In ________ after getting new computers became ________________ in size, got cleverer and cleverer in intelligence, and became __________________ in speed. Then they could be connected with other computers by a network, and ________ could talk to them using BASIC. In the 1970s people began to bring them into their homes.
