CLASSIFICATION OF COMPUTERS Computer can be classified into three aspects: . Representation of numbers . Degree of specialization . Types of application Representation of Numbers There are three basic aspects of Computers, which are digital, analog and hybrid. Digital Computer: This aspect of computer operates on numbers directly. It handles numbers discretely and precisely rather than approximately. Examples of digital computers are digital watch, digital phone and digital radio. Analog Computer: This aspect of computer deals with quantities that are continuously variable e.g. speedometer, electric meter, water meter, thermometer. Hybrid Computer: This computer combines the features of both analog and digital computers. They handle data in both quantities and variable. Degree of Specialization There are two basic types – special and general-purpose computer. Special Purpose Computer: This aspect of computer is designed to perform one or specific task. The program of this aspect of computer is in-built into the machine permanently. For instance, special purpose computers are used for solving navigation problems in aircraft and ships. General Purpose Computer: These computers have the ability to handle a wide variety of different programs and to solve many different problems. Types of Application There are two types – Scientific and Business Applications. Scientific Applications: These computers are designed to handle scientific application more effectively. They require small volume of data input and output. Business Data-Processing Application: These computers are designed to handle business data processing applications. They need a large data file, input storage, output storage devices and large storage capabilities. For more updates, visit luckyfemtech.ucoz.org
