Computer
What is computer : computer is associate degree device that's designed to figure with info. The term computer comes from the Latin term computare this implies to calculate or programmable machine. computer can't do something while not a Program.
It represents the decimal numbers through a string of binary digits. The Word 'Computer' sometimes refers to the middle Processor Unit and Internal memory.
Charles Babbage is termed the "Grand Father" of the pc. the primary mechanical computer designed by Charles Babbage was referred to as Analytical Engine. It uses store within the sort of punch cards.
Computer is a sophisticated device that takes knowledge|data|information} as input from the user and processes these data below the management of set of directions (called program) and provides the result (output) and saves output for the longer term use. It will method each numerical and non-numerical (arithmetic and logical) calculations.
Digital Computer Definition
The basic parts of a contemporary information processing system are: device, Output Device, electronic equipment Unit (CPU), mass memory device and memory. A Typical fashionable computer uses LSI Chips. Four Functions concerning computer are:
accepts knowledge
Input
processes knowledge
Processing
produces output
Output
stores results
Storage
Input (Data):
Input is that the raw info entered into a computer from the input devices. it's the gathering of letters, numbers, images etc.
Process:
Process is that the operation of knowledge as per given instruction. it's altogether internal method of the pc system.
Output:
Output is that the processed knowledge given by computer when processing. Output is additionally referred to as as Result. we are able to save these ends up in the storage for the longer term use.
Computer Classification: By Size and Power
Computers take issue supported their processing skills. they're classified consistent with purpose, knowledge handling and practicality.
According to practicality, computers area unit classified as:
• Analog Computer: A computer that represents numbers by some ceaselessly variable physical amount, whose variations mimic the properties of some system being shapely.
•Personal computer a private computer may be a computer little and low price. The term"personal computer" is employed to explain desktop computers (desktops).
• Workstation: A terminal or personal computer in an exceedingly network. during this context, digital computer is simply a generic term for a user's machine (client machine) in distinction to a "server" or "mainframe ."
• Minicomputer: A digital computer is not very mini. At least, not within the manner most people consider mini. you recognize however massive your pc is and its connected family.
• Mainframe: It refers to the type of enormous computer that runs a whole corporation.
• Supercomputer: it's the largest, fastest, and most costly computers on earth.
• Microcomputer: Your pc may be a personal computer.
