The Development of Computers

1. The first computers used thousands of separate elec­trical components connected together with wires. In the late 1940s, computers were made using vacuum tubes¹, resistors, and diodes. These computers were called first generation computers.

2. In 1956, transistors were invented. Transistors are made from materials called semiconductors. Computers using transistors were called second generation com­puters. Second generation computers were smaller than first generation computers. Second generation computers also used less electrical power. Both first and second gen­eration computers were very expensive.

3. Computer components (such as transistors, diodes, resistors) can now be made from semiconductor mate­rials of different shapes. Nowadays, complete circuits can be made from a single piece of semiconductor, called a chip. Such circuits are called integrated circuits² (ICs).

4. Computers using integrated circuits were first produced in the 1960s. They were known as third genera­tion computers. Their integrated circuits had about 200 components on a single chip. Today, we can produce more than 100, 000 components on a single chip. A chip can be as small as 0.5 cm square.

With the invention of chips, computer manufacture has become much simpler. The manufacturer does not have to connect thousands of components together. Most of the connections are made inside the chip. It is even possible to build a complete in a single chip. A processor on single is called a microprocessor.
