Types of Computers

Broadly, computers can classify based on:
(a) The data handling capabilities and the way they perform the signal processing, and
(b) Size, in terms of capacities and speed of operation.

Based on the type of input they accept, the computer is of three types:
We’ll be covering the following topics in this tutorial:

• 
  1. Analogue Computer
  
• 
  2. Digital Computer
  
• 
  3. Hybrid Computer

  Different kinds and sizes of computer
  

1. Analogue Computer
Everything we hear and see is changing continuously. This variable continuous stream of data is known as analogue data. Analog computer may be used in scientific and industrial applications such as to measure the electric current, frequency and resistance of the capacitor, etc..
Analogue computers directly accept the data in the measuring device without first converting it into codes and numbers.
Cases of analogue computer are temperature, pressure, telephone lines, Speedometer, immunity of capacitor, frequency of signal and voltage, etc..
2. Digital Computer
The digital computer is the most widely used and used to process data with numbers using digits, usually utilizing the binary number system.
A digital computer intended to do calculations and logical operations at a high rate. It takes the raw data as digits or amounts and procedures using applications stored in its memory to make output. All modern computers such as laptops and desktops we use at office or home are digital computers.
It works on data, such as magnitudes, letters, and symbols, which expressed in binary code–i.e., with just the two digits 1 and 0. By counting, comparing, and manipulating those digits or their mixtures by a pair of instructions stored in its memory, a digital computer may perform such tasks to control industrial processes and also control the operations of machinery; examine and organize vast amounts of company data; and mimic the behaviour of dynamic systems (e.g., international climate patterns and chemical reactions) in scientific study.
Digital computer supplies accurate result but they’re slow compared to an analogue computer.
