There are 3 types of hardware. the input/ output devices, CPU and the memory. There are 2 types of softwares. The OS/ Operating System and the applications.
There are many types of computers. Each with different kind of system.
The digital computer operates on data, including magnitudes, letters, and symbols, that are expressed in binary form . For example, the computers we use today. The analog computer is a computer that represents data by measurable quantities, as voltages or, formerly, the rotation of gears,in order to solve a problem, rather than by expressing the data as numbers. An example is an analog wall clock. The hybrid computer is a combination of digital and analog computer just like in aircrafts.
