What is Digital computer?

The term Digital means consisting of discrete levels. Devices that work (manipulate) with these discrete stages, e.g. performing arithmetic and logical operations on them are known as Digital computer. All computers are generally digital computer. These types of computers are primarily involved in data processing and problem-solving for specific programs. In digital computers, data is stored as digits (numbers) and processes. letters, words, symbols and complete texts are digitally represented, i.e., using only two digits 0 and 1. Digital computers have a lot of memory for storing data.

 

Digital computers are constitute input-output devices, main memory, control unit and arithmetic logic unit. Data is processed with logical circuits, also known as digital circuits. All the circuits processing data inside a computer function in an extremely synchronized mode; which is further controlled using a steady oscillator acting as the computer’s ‘clock’. Hence, the digital computers operate on very high speed and are able to perform quick solution to problems, which is not possible for a human being to do manually. 

Digital computers perform counting rather than measuring the data, which is done in analog systems. A digital computer performs sequential operations one at a time and operates on discrete(non continuous) numbers. They are more accurate, precise, and faster than analog computers.
