What Is Computer?

           an electronic device for storing and processing data, typically in binary form, according to instructions given to  it in a variable program.

               a person who makes calculations, especially with a calculating machine.

         What is computer Short answer?

         A computer is a device that accepts information (in the form of digitalized data) and                    manipulates it for some result based on a program or sequence of instructions on how                  the data is to be processedToday's computers have both kinds of programming.

1-LCD

     LCD (liquid crystal display) is the technology used for displays in notebook and other smaller           computers. Like light-emitting diode (LED) and gas-plasma technologies, LCDs allow displays to be much thinner than cathode ray tube (CRT) technology.

      2-CPU

2-CPU

   CPU (pronounced as separate letters) is the abbreviation for central processing unit.     Sometimes referred to simply as the central processor, but more commonly called processor, the CPU is the brains of the computer where most calculations take place.

     What is the CPU?

    A central processing unit (CPU) is the electronic circuitry within a computer that carries     out the instructions of a computer program by performing the basic arithmetic, logic,           controlling and input/output (I/O) operations specified by the instructions.

Why do we use keyboards?

Some people wound up typing so fast that the mechanical rods attached to the keys would stick to each other. To resolve this, the QWERTY keyboard was developed. It placed keys in such a manner that the most used letters were spaced out so that the rods were less likely to clash into each other when typing.

4-Mouse

           

What is the mouse?

A mouse is a small handheld input device that controls a computer screen's cursor or pointer in conjunction with the way it is moved on a flat surface. The mouse term name originates from its likeness to a small, corded and elliptical shaped device that looks like a mouse tail.
