What Is Concept Of Computer?


 

Computer Concepts -

An Overview of the Computer In today's world, computers are used for every task. Our regular activities include: using social media, looking for entertainment, paying bills, buying groceries, working from home, chatting with friends, etc., and should be in every way possible utilizing a PC. Therefore, not only is it essential to know how to use a computer, but also to comprehend its components and functions.

From the beginning to the end, this topic covers every computer-related concept in detail. In addition, the idea of computer literacy, including its definition and functions, is discussed. You learn about the parts of a computer, the idea of hardware and software, how data and information are represented, how data processing works, and how IECT can be used.

How does a computer work?

An electronic device that receives data from a user processes it, produces results, displays them to the user, and stores the results for later use is known as a computer.

Unorganized facts and figures without any further context, patterns, or other information are referred to as data.

Information is structured data—that is, data that has been organized, interpreted, and processed. A computer is used to process data and turn it into information.

Elements of PCs

A PC carries out the accompanying roles −

Getting Information

Information is taken care of on PC through different information gadgets like a console, mouse, computerized pens, and so on. Scanners, CD-ROMs, pen drives, and other devices can also provide input.

Processing the data 

The data's operations are carried out by the programs' instructions.

Following processing, the information is stored in either the primary or secondary storage area.

Creating yield

The handled data and different subtleties are conveyed to the rest of the world through yield gadgets like screens, printers, and so forth.

Computer History

 The computer has been around for a long time. There are five main computer generations. Computers' capabilities have been altered by numerous technological advancements throughout history. As a result, systems become smaller, more powerful, and more cost-effective. The following is a brief overview of the history of computers: First Generation (1940–1966) The hardware used in the first generation of computers consisted of the following features and components: Punch Cards and Vacuum Tubes

The characteristics of the first generation of computers are as follows:

• It supported machine language.

Due to the use of vacuum tubes, it was large and had a slow performance.

• It had limited storage space.

• It produced a lot of heat and used a lot of electricity.

The memory contained 4,000 bits.

Data Input The computer only accepted data from punched cards and paper tapes through hard-wired programs.

Examples include 

• ENIAC

• UNIVACTBM 701 Second Generation (1956–1963) Several improvements made to first-generation computers led to the development of second-generation computers. Hardware The hardware that was used in the second generation of computers consisted of :

• Transistors

• Magnetic Tapes Features It had features like 

• Batch operating system

• Faster and smaller than the previous generation 

• Dependable and power-saving 

• More affordable than the prior generation Memory The memory could store 32,000 items.

Data Input Punched cards served as the method of input.

The following are examples of computers from the second generation: Honeywell 400, CDC 1604, and IBM 7030. Third Generation (1964–1971): Hardware: Integrated Circuits made from semi-conductor materials; Large capacity disks and magnetic tapes; Features: Supports time-sharing operating system; Faster, smaller, more reliable, and less expensive than previous generations; Easy to access Memory: The memory's capacity was 128,000 bits.

Data Input Keyboards and monitors were used for input.

Examples of third-generation computers include: • IBM 360/370; • CDC 6600; • PDP 8/11; • Fourth Generation (1972–2010): • Hardware: • ICs with Very Large Scale Integration (VLSI) technology; • Semiconductor memory; • Magnetic tapes and floppy disks; • Features: It supports features such as: • Multiprocessing & distributed OS; • Object-oriented high level programs are supported; • Small and easy to use; hand-held PCs have advanced

•             No outside cooling required and reasonable

•             This age saw the advancement of organizations and the web

•             It saw the advancement of recent fads in GUIs and mouse

Memory

The limit of the memory was 100 million pieces.

Data Input The improved hand-held devices, keyboard, and mouse served as the means of input.

Examples include the Apple II; the VAX 9000; the CRAY 1 (supercomputers); the fifth generation (from 2010 to the present); these are the most recent and cutting-edge computers. Fifth-generation computers are more user-friendly and reliable than previous generations thanks to significant changes in their components and operations.

Hardware In the fifth generation of computers, the hardware includes: • Integrated Circuits with VLSI and Nanotechnology; • Large capacity hard disk with RAID support; • Powerful servers, Internet, and Cluster computing Features It supports features such as • Powerful, inexpensive, dependable, and simple to use.

• Compact and quicker because of the purpose of equal processors and Huge Scope Coordinated Circuits.

• Software development can happen quickly.

Memory The memory's capacity is limitless.

Information Info

The info is given through CDROM, Optical Circle, and other touch and voice delicate info gadgets.

Examples: IBM, Pentium, and PARAM are examples of fifth-generation computers.
