GENENERATIONS OF COMPUTER:

 GENERATIONS:

There are five generations of computer which are following:

1ST GENERATION:

  • ECKERT and MAUCHLY developed the first electronic computer in ENIAC in 1946 in USA.
  • Vacume tube is the core element of 1st generation.
  • The time period of 1st generation of computer was from 1946 to 1959.
  • Consumes lot of electricity.
  • It is not portable.
    2ND GENERATION:
  • The second generation of computer are IBM 700 ATLAC and ICL 1901
  • Transistor was the core element of 2nd generation
  • The time period of 2nd generation was from 1959 to 1965
  • Required less power to operate.
  • Smaller reliable and faster than 1st generation of computer.
3RD GENERATION:
  •  The 3rd generation of computer are IBM 360 NCR 395 TDC developed by JACK KILBY.
  • Integrated circuits( Ics) was the core element of the 3rd generation.
  • The time period of 3rd generation  computer was from 1965 to 1971.
  • Development of minicomputer.
  • In this generation O.S was developed.
4TH GENERATION:
  • The fourth generation of computer are DEC 10 star 1000 etc.
  • Large scale integrated circuits was ( LSICS) and (VLSICS).
  • The time period of 4th generation computer was from 1971 to 1985.
  • Semi conductor were used for primary storage.
  • Development of micro computer or PC.
5TH GENERATION:
  • The fifth generation of computer are desktop laptop etc.
  • Ultra large scale integration (ULSI) was the core element.
  • The time period of fifth generation computer is 1985 till date.
  • RAM and ROM are used for primary storage.
  • All high level programming languages like C++, java ,python etc included.

COMPONENETS OF COMPUTER HARDWARE:

 COMPONENTS OF COMPUTER HARDWARE: Different componenets of a computer hardware are as follows: Input devices Output devices System unit Storage devices EXPLAIN:  The data and instructions given to the computer is called input. A hardware component used to enter data and instructions into the computer is called input device.  Different types of input devices are used to input data into the coputer are as follows. Keyboard Mouse Microphone Scanner Digital cemera     2.     The data  processed into useful information is called output. A hardware component used to display information to the user is called output device. Most commonly used output devices are as follows: Moniter Printer Speaker 3.       System unit is a case that contains electronic components of the computer used to process data. All computer systems must a system unit.  The electronic in the system unit are connected to the motherboard. Motherboard is a...

WHAT IS SOFTWARE?

  https://techinfo4243.blogspot.com A LITTLE INTRO OF A SOFTWARE: A set of instruction given to the computer to  solve a problem is called software. A computer works according to the instructions written in the software. It is also known as program . Different softwares are used to solve different problems . The computer cannot perform any task without a software.  EXAMPLES: Software for creating documents such as MS WORD. Software for graphics such as adobe photoshop. RELATION OF SOFTWARE AND HARDWARE: Software is a set of instructions that tells the computer what to do . Hardware cannot perform any task without software. The software cannot be executed without hardware. A computer becomes useful when hardware and software are combined.  WHAT IS DATA? A collection of raw facts and figures is called data . (It means the data that is meaningless at that time) Data is given to the computer for processing.  Data is collected from different sources.  WHAT IS IN...

OPERATING SYSTEM IN DETAIL":

OPERATING SYSYTEM: NOTE: On the request of an viewer in the previous article i will explian the operating system in detail. I will try my best hope you all understand it. First of all as you know that operating system is an interaction between the hardware and users. If we want to know that what is software? we can say that  Set of tested programms and documention and we can also say that set of instructions that tells the computer what to do. There are two types of software:     1-System software Basicaly it is a paltfrom that is used to run the overall application software. OR we can say that it operates the application software like LINKER  LOADER DEBUGGER    2. Application software Designed for any specific task like WINDOWS MEDIA PLAYER VLC MS OFFICE Our mission is to know how an operating system is more important for interaction between a hardware and user? I will give an example to clear your concept. EXAMPLE: If you want to ON/OFF  an FAN . Ss ...
