What are Digital Computers? The digital computer is a digital system that performs various computational tasks. The word digital implies that the information in the computer is represented by variables that take a limited number of discrete values. A Digital computer can be considered as a digital system that performs various computational tasks. The first electronic digital computer was developed in the late 1940s and was used primarily for numerical computations. By convention, the digital computers use the binary number system, which has two digits: 0 and 1. A binary digit is called a bit. A computer system is subdivided into two functional entities: Hardware and Software. The hardware consists of all the electronic components and ...
