what is COMPUTER ?

 

DEFINATION OF A COMPUTER :-

 COMPUTER is an electronic machine which performs Arthimetic and Logical operations.       Computer is an advance electronic machine which takes instruction as INPUT and perform operations according to given instructions, and produce result as OUTPUT.computer also stores instructions for future use .

Basically, The word computer which has been made by the ‘GREECK’ word ‘COMPUTE’ means CALCULATION.

*   A COMPUTER is a system that accepts information (in the structure of digitalized data) and manipulates it for some end result primarily based on a program, software, or sequence of instructions on how the records is to be processed.

 

   According to above definition computer has perform FOUR functions :-

 

INPUT ----------à PROCESS>>>>>>>>>>>>STORE --------------à OUTPUT

PROCESSING CYCLE 

 

INPUT – It is a type of method which is used to gather data and information for supplying into computer or taking data information for computer.

PROCESS – It is such type of method which perform operations on  particular information or datathat is supplied by input.

OUTPUT – It is a method that is used to give result according to perform operation which is supplied by input .

STORE – It is used to store data and information for future use/requirement.

                            

Major sorts of computers :-

 

Analog Computer - represents statistics via measurable quantities

Desktop Computer - a private pc that suits on a desk and is regularly used for enterprise or gaming

Digital Computer - operates with numbers expressed as digits

Hybrid Computer - combines points of each analog and digital computers

Laptop (notebook) - an effortlessly transported pc that is smaller than a briefcase

Mainframe (big iron) Computer - a centralized pc used for massive scale computing

semiconductor chip microprocessor.

Minicomputer - an antiquated time period for a pc that is smaller than a mainframe and large than a microcomputer

Netbook - a smaller and much less effective model of a laptop

Personal Computer (PC) - a digital laptop designed to be used through one man or woman at a time

Smartphone - a cell smartphone designed with an built-in computer

Supercomputer - a excessive performing pc that operates at extraordinarily excessive speeds

Tablet pc (tablet PC) - a wi-fi private pc with a contact screen

Workstation - tools designed for a single consumer to entire a specialised technical/scientific taskHistory of Microcomputer - normally referred to as a PC (personal computer). Uses a single integrated the present day computer

Most histories of the present day PC start with the Analytical Engine anticipated by means of Charles Babbage following the mathematical thoughts of George Boole, the mathematician who first cited the standards of good judgment inherent in brand new digital computer. Babbage's assistant and collaborator, Ada Lovelace, is stated to have added the thoughts of software loops and subroutines and is occasionally viewed the first programmer. Apart from mechanical calculators, the first surely useable computer systems started with the vacuum tube, accelerated with the invention of the transistor, which then grew to be embedded in giant numbers in built-in circuits, eventually making viable the distinctly low priced private computer.Modern computer systems inherently observe the thoughts of the saved software laid out by way of John von Neumann in 1945. Essentially, the application is study by using the laptop one training at a time, an operation is performed, and the pc then reads the next instruction.

 

From the mid-1900s to the present, the development of computer systems is divided into 5 generations. While the yr span for every era varies relying on the reference source, the most diagnosed generational timeline is below.

 

1940 to 1956

First era computer systems had been room-sized machines that used vacuum tubes for circuitry and magnetic drums for restrained inner storage. These machines used punched playing cards for information enter and a binary computer code (language). Examples of first technology computer systems encompass the ABC (Atanasoff Berry Computer), Colossus, IBM 650 and the EDVAC (Electronic Discrete Variable Computer).1956 to 1963

Second technology computer systems changed vacuum tubes with transistors, used magnetic tape storage for accelerated storage capacity, used BAL (basic assembler language) and persisted to use punched playing cards for input. Transistors drew much less electricity and generated much less warmness than vacuum tubes. Examples of second-generation computer systems encompass the IBM 7090, IBM 7094, IBM 1400, and the UNIVAC (Universal Automatic Computer).

 

1964 to 1971

Third technology computer systems used ICs (integrated circuits) with a number of transistors and MOS (metal oxide semiconductor) memory. Smaller, more cost effective and quicker than their predecessors, these computer systems used keyboards for input, monitors for output, and employed programming languages such as FORTRAN (Formula Translation), COBOL (Common Business Oriented Language) and C-Language. Examples of 1/3 era computer systems consist of the IBM 360 and IBM 370 series.1972 to 2010

Fourth technology computer systems used built-in circuits and microprocessors with VLSI (very giant scale integration), RAM (random get admission to memory), ROM (read-only memory), and high-level programming languages such as C and C++. The introduction and enlargement of the World Wide Web and cloud computing (the capacity to supply hosted offerings the use of the Internet) appreciably greater computing competencies throughout this period. Examples of fourth technology computer systems encompass Apple's Macintosh and IBM's PC.

 

2010 and beyond

Fifth technology computer systems are based totally on AI (artificial intelligence), use massive scale built-in chips and extra than one CPU (processor). Fifth technology computer systems reply to herbal language input, remedy quite complicated problems, make selections thru logical (human-like) reasoning and use quantum computing and nanotechnology (molecular manufacturing). Fifth era computer systems and applications permit a couple of applications (and computers) to work on the identical trouble at the identical time in parallel.

 

The creation of the Internet, cloud computing, and excessive bandwidth information transmission permits packages and information to be disbursed over a community rapidly and efficiently, whilst software applications and software program make computer systems the equipment of preference for such matters as phrase processing, databases, spreadsheets, presentations, ERP (enterprise aid planning), simulations, education, CMS (content administration systems), gaming and engineering.
