Digital Computers are that kind of computing machines which work on the principle of binary mathematics. Digital computing machines when clubbed with Analog computers produce Hybrid computers. The digital systems work on the principle of binary mathematics. In binary mathematics all calculations are represented through “0” and “1”.
You have often heard about the word “Byte”, “Mega Byte”, “Kilo Byte”. But what is a Byte? A single Byte is a group of 8 numbers or bits represented through a code series comprising of “0” and “1” .The combination of the digital signal can solve a number of mathematical operations. It is interesting to note that the fundamentals of mathematics applied are addition, subtraction, multiplication and division. But the chief problem is that though it can solve mathematical problems at a tremendous speed, it cannot perform bulk operations simultaneously. For this purpose, digital systems by themselves cannot give very precise results. Hence, for greater efficiency, the Digital systems do not find much application.
Data Processing In Digital Computers Digital computers function with the help of logic circuits. A reliable oscillator helps in the proper synchronization of various logic circuits that are responsible for processing data in the digital computers. In better quality computers, the oscillation rate might even be a billion cycles per second. Operating at such high speed, it can process more than billions of logic and arithmetic problems.
A digital computer with the help of binary system cannot only perform mathematical problems but also combine the bytes to produce desired graphics, sounds, images and other such commands.
