Generation of Computer




     First Generation (1946-1959)

This computer used thousands of vacuum tube ENIAC, EDVAC, UNIVAC, EDSAC and IBM 701 belong to this generation. Vacuum whose a high speed electronic device available at that time. The vacuum tube good perform operation this generation and they were replete as 1st generation the instruction where return and machine language and assembly language and where input a computer punched paper card.


Second Generation (1959-1965)

In second generation of computer transistor where used which where a better electronic device as compere to vacuum tube. The high level programming language such as FORTRNT (Formula translation), COBOL (Common Business Oriented Language), ALGOL (Algorithm Language), etc.


Third Generation (1965-1971)

Integrate circuit (IC) where developed in 3rd generation which consisted combination of transistors, resistors and capacitors at the start the SSI (Small Scale Integration) whose use which contain 10-20 compounds letters MSI (Medium Scale Integration) whose used which of 100 compounds.

The period of third generation was from 1965-1971. The IC was invented by Jack Kilby.



Fourth Generation (1971-1980)

In this generation LSI (Large Scale Integration) made possible to integrate thousands of compounds on single chip. LSI whose followed by VLSI (Very Large Scale Integration) which contained 1 million on a single chips.


Fifth Generation (1980-onwards)

The ULSI (Ultra Large Scale Interface) which allowed millions of compounds in a single chip become popular this generation.

  • Portable PC is (notebook Computer) which were smaller then PCs where popular in this generation.
  • Optical Disk such as CDROM (compact Disk Read Only Memory), DVD (Digital Video Disk) become popular.
  • Internet Become very popular and it allowed the user to access large amount of information stored anywhere in the world.
  • High up-time due to hot-pluggable components.
  • This generation used stinted high level programming language that allowed exit program between differences.

The Basics You should Know For programming! For what Programming language used? A computer programming language is a language used to write computer programs, which involves a computer performing some kind of computation or algorithm and possibly control external devices. Example: printers, disk drives, robots, and so on. Basics elements for programming History Of Programming Language You want to Learn: Firstly, collect information regarding  that programming language you want to learn such as language developed by whom ? , In which year ? , Was developed for which purpose , Demand and scope of the language now-a-days! What are keywords? :  A keyword is a word that is reserved by a program because the word has a special meaning. Keywords can be  commands or parameters. Every programming language has a set of keywords that cannot be used as variable names. Keywords are sometimes called reserved names .For Example: we call Apple to  a fruit which is actually a Apple A...

A flowchart is a graphical representation of an algorithm. It makes use of symbols that are connected among them to indicate the flow of information and processing. Symbols of Flowchart      Start/End (also known as Terminal) An Oval represents a start and end point of flowchart. Input/Output A parallelogram represents input or output. Take input from device and display the output from device. Process A rectangle represents a process. All arithmetic process (Addition, Subtraction, Multiplication, Division) are indicated by symbol. Decision A diamond indicates a decision. These symbols based on yes/no or true/false operations. Arrows A line is a connector that shows relationships between the representative shapes.
