4 computer generations
Second Generation computers were used in 1959 to 1964.With transistor technology, the second generation computer was made. Transistors were small, fast and more reliable for less power.
Third Generation computers were used in 1965 to 1970 Third generation computers used things like the time and business tasks.
The development of microprocessor chips led to the making of inexpensive computers. These computers use a large scale integrated circuits and reduced the size and cost of computers.
Input and output devices
A hard drive is memory for a computer meaning when the power is removed the memory is still there. It is called a hard drive because the memory is a number of rigid aluminum discs not like the old floppy drives which were flexible.
A rigid magnetic disc fixed permanently within a drive unit and used for storing computer data
CPU (Central Processing Unit)
The motherboard serves to connect all of the parts of a computer together. The CPU, memory hard drive, optical drives, video card , soundcard and other ports and expansion cards all connect to the motherboard directly or via cables.
