what is computer?

     

    The computer is Associate in Nursing device wont to store data and method it. the term laptop comes from the Latin term 'Computare' which suggests to calculate. it's believed that the analytical engine of the primary laptop that was unreal by Charles Babbage . Charles Babbage is additionally called the daddy of the pc.

Full from of laptop as follows

     C- normally

       

    O- Operated

    M- Machine 

    P- notably

    U-Used

    T-Technical

    E-Educational 

    R-Research

 normally operated machine notably employed in technical and academic analysis.

Basic a part of laptop

   

 processor- it executes directions from software system and hardware.

 Memory- it's the first for knowledge transfer between the central processing unit and storage.

  Motherboard -it is that the half that connects all different components or elements of a laptop.

     Storage device- it for good stores the information.

     Input device- it permits you to speak with the pc or to input file.

       Output device-it allows you to visualize the output.

Computers ar divided into five sorts in keeping with their size functions

        1.Micro laptop

        2. mini laptop

        3. mainframe

        4. Super laptop

        5. Workstations 

Uses of laptop

 laptop is incredibly helpful for every people .

  1.serching data

     with the assistance of laptop, you'll search data on the required topic. with the assistance of web we are able to notice each data of the word.

   2.Office work

  with the assistance of laptop we are able to do numerous tasks of the bank. like checking balance or cash transfer.

   3.Online looking

 on-line looking is incredibly well-liked today for buying numerous things. with facilitate of laptop, we are able to purchase numerous factor.

  Your personal data are often purloined whereas doing on-line works on your laptop. which might cause you loss. Therefore, it's necessary to require correct precautions.

Generations of laptop

First Generation :-

 the amount from 1940 to 1956 is thought because the initial generation of computers. within the initial generation of computers, electronic signals were controlled and transmitted with the assistance of vacuum tubes. These were wont to create calculations. These computers were giant and significant in size. These computers generate tons of warmth, so that they want Associate in Nursing cooling system (AC).

Second Generation :-

 the amount 1956 to 1963 is thought because the second generation of computers.

 during this generation of computers, transformers were used rather than vacuum tubes. These computers were

smaller in size than the primary generation computers. They were able to calculate abundant quicker than the primary generation.

Third Generation :-

 the amount 1963 to 1971 is thought because the third generation of computers.

 during this generation, element chips were replaced by transistors in computers.

  Integrated Circuits (ICs) were employed in element chips. that created it attainable to scale back the dimensions of computers. the employment of integrated circuits in computers helped in increasing the speed of those

computers.

Fourth Generation :-

 the amount 1971 to 1980 is thought because the fourth generation of computers.

  Microprocessors were employed in fourth generation computers. Microprocessors chips were factory-made during this generation. terribly giant Scale Integrated (VLSI) circuits were employed in this generation of computers. With that thousands of transistors may be placed during a single chip. Fourth-generation computers were additional powerful, compact, reliable, and cheaper.

Fifth Generation :-

 the amount from 1980 to nowis called the fifth generation of computers. ULSI (Ultra giant Scale Integration) technology began to be employed in this generation. These generations ar supported computer science.

 within which computers are often created to assume like humans. Some computers of this generation ar Desktop, Laptop, Notebook, Ultrabook, Chromebook
