Types of Computers Bank Material for Bank Exams
TYPES OF COMPUTERS :
An Electronic Device that accepts the Input , processes, produces output and Stores the data is called COMPUTER.The basic computer is an important topic for the upcoming IBPS exam and also pertaining to any other bank exams.It can store, retrieve and process the data. Computers are basically classified into 2 categories based on their Principle of Operation and Nature of Configuration. The computers categorized on Operational Principle can be further divided into 3 categories such as Analog, Digital and Hybrid Computers. Similarly, the computers classified on Configuration nature can also be categorized into 4 Categories such as Micro, Mini, Mainframe and Super Computers.
ANALOG COMPUTERS :
Analog Computer works on continuous range of varied values of Physical quantities like Temperature, Speed, Voltage, Pressure etc. and generates approximate results.
DIGITAL COMPUTERS :
The Digital computer is designed with digital circuits in which there are two levels (logic 0 and logic 1) for an input and output signal. This computer is very much useful to solve complex problems in Engineering and Technology and hence it has increasing use in the field of design, research and data processing. If this digital computer is used for any type of application, then it is called as General Purpose Computer and Special Purpose Computer when it is used for specific application/program.
HYBRID COMPUTERS
A computer used for automatic operations of complicated physical processes to transform the data into suitable form is called Hybrid Computer. The conversion of analog data as digital and vice-versa is the advantage of this computer.
MICRO COMPUTERS
The most commonly used computer by everybody at any place is called Micro Computer, in which Microprocessor is the major source of operation. Desktop Computers, Laptops, notebook computers, Palmtop computers, In-car Computers (Carputers), Handheld Game Consoles, Programme Calculators, Table Computers, Smart Phones, Smart Books, Personal Digital Assistants (PDAs) etc. are the examples for this computer.
DESKTOP COMPUTER
LAPTOP COMPUTER
IPAD COMPUTER
MINI COMPUTER :
The multi-user midrange Computer that works in between smallest multi-user systems and largest single-user system is called as Mini Computer.
MAINFRAME COMPUTER :
The computer capable for processing large amount of data very quickly to service multiple users from the smaller and single user machine is called as Mainframe Computer. These computers are used in Large Organizations/Establishments such as Government, Banks, Corporations etc. They respond to up to 100s of millions of users at a time and measured in MIPS (Million Instructions per Second).
SUPER COMPUTER :
An extremely fast computer capable to perform hundreds of millions of instructions per second is called Super Computer. These computers are used for applications of intensive numerical computations such as Weather forecasting, Stock Market Analysis, Scientific Calculations, Animated Graphics, Research Analysis etc.
