Digital Computers
There are two distinct families of computing device available to us today, the all pervasive digital computer and almost forgotten analog computer. These two types of computer operate on quite different principles.
Digital computer operates on digital data such as numbers and proceeds in discrete steps from one state to next. It uses binary number system in which there are only two digits 0 and 1. Each one is called a bit.
The digital computer is designed using digital circuits in which there are two levels for an input or output signal. These two levels are known as logic 0 and logic 1. They can give more accurate and faster results.
Technically, depending on how the terms “digital” and “computers” are defined, devices such as calculators, cameras, smartphones or any accessory with a micro-processing chip could be considered a type of digital computer. However, today digital computers are most commonly referred to as personal computers, also known as desktops and laptops. Dell, Hewlett-Packard and IBM are only a few of many companies manufacturing personal computers.
Digital computer is well suited for solving complex problems in engineering and technology. Hence digital computers have an increasing use in the field of design, research and data processing.
Digital computers in general are classified into major categories based on.
(a). According to the purpose of the computer.
(b). According to the operation size of computer.
(a) Classification as per purpose of the computer:
Classification of digital computer as per the purpose of their use-:
1. General purpose digital computers.
2. Special purpose digital computer.
1. General Purpose digital computers: These computers are theoretically used for any type of applications. These computers can be used in solving a business problem and also used to solve mathematical equation with same accuracy and consistency. Most of the computers now are general purpose digital computers.
