Introduction l.jpg








System has wide variety of meanings in various contexts, but here a system is something that takes input and does some processing work and gives output.

Examples: Electrical Generator

Educational Institute is a system

Doctor, etc.,

Questions: Is there any system which takes input but never produces output and Vice-versa

What is a System?

Introduction cond l.jpg




Introduction Cond.,

What is Data?

What is Information?

Example for Data Processing Systems is Computer

If any system takes data as input and producing information as output, such a processing is called “Data processing system”.

What is computer l.jpg
What is Computer ?

Que’s Computer Users Dictionary: 'A machine capable of following instructions to alter data in a desirable way and to perform at least some of these operations without human intervention'.

Microsoft Press Computer Dictionary, 3rd Ed.: 'any machine that does three things: accepts structured input, processes it according to prescribed rules, and produces the results as output'.

Oxford dictionary: as “an automatic electronic apparatus for making calculations of controlling operations prescribed in numerical or logical terms.

Collins English Dictionary: 'A device, usually electronic, that processes data according to a set of instructions'

Computer definition l.jpg
Computer Definition

“A computer is a complex system incorporating diverse technologies. Typically, electronic technology is used for computation, magnetic for long-term storage, and electromechanical for input and output.”

Architecture organization l.jpg
Architecture & Organization

Computer architecture deals with the functional behavior of a computer system as viewed by a programmer (like the size of a data type – 32 bits to an integer).

Computer organization deals with structural relationships that are not visible to the programmer (like clock frequency or the size of the physical memory).

Basic function of computer l.jpg
Basic function of Computer

  • The key questions

    • How are these instructions supplied to the computer?

    • How are they interpreted and executed?

answer to these questions along with the discussion on the Von-Neumann Architecture.

The basic function is performed by a computer is the execution of a program is sequence of instructions which operates on data to perform certain tasks.

Von neumann architecture l.jpg
Von Neumann Architecture

All most all computer designs based on concept developed by John Von Neumann referred to as “Von Neumann architecture”.

Virtually all-contemporary computers are based on concepts developed by John von Neumann who designed the IAS computer.

IAS Computer

Developed by John Von Neumann in 1940 at Princeton University.

In IAS computer, IAS stands for Institute for Advanced Studies.
