               Second Generations Computer(1958-1963):                                                                                       The second generations computer  used transistor. The transistor was invented by three scientists William Shockley ' John Bardeen and Walter Brattain at Bell Lads in 1947. The size of the computer was decreased by replacing vacuum tubes with transistors. The example of second-generations computer are IBM 7094 series' IBM 1400 series and CDC 164 etc. Transistor              Advantage   .   These computers were smaller in size than first generation.                            ...

It was made in 1944 with the help of IBM It was the first  automatic electro mechanical computer. It could multiply ten digits in five seconds. Mark 1 was very reliable but huge in size.  Mark I ENIAC:             ENIAC stands for Electrical Numerical Integrator and calculator. It was the first general purpose electronic computer. It was designed by John William Mauchly and John Eckert in 1946. It was very heavy and large in size. It consumed a large amount of power. It could perform 5000 addition per second. It used decimal number system. ENIAC EDVAC:              EDVAC stands for Electronic Discrete Variable Automatic Computer. It was an electronic computer designed by John Mauchly and John Eckert. It used binary system for calculations instea...

        Leibniz Calculator:                                        Von Leibniz was a German scientist. He invented a calculating machine in 1694. It was the first calculator that could add, subtract , multiply and divide. It was more reliable and accurate than Pascal's calculator.                                                                                            Von Leibniz         Jacquard's Loom:                                  Jacquard's Marie form France invented a machine Jacquard's Loom in 1801. The machine could read punch...

       History of Computer:                                           Computer was invented because "necessity is the mother of invention" . Man always searched for a fast calculating devices. It took a long time to invent the digital computer.            A brief  history the invention of the computer is as follows:                    Abacus:                           Abacus was first computing devices. It was developed 500 years ago by Chinese. It was used to perform simple addition and subtraction. Abacus was a wooden rack with horizontal wires containing beads. The beads could move easily. All simple arithmetic calculation were performed by moving the beads.                ...

 System unit:                       System unit is a case that contains different electronic components of computer used to process data. All computer system have a system unit. The electronic components in the system unit are connected to motherboard. Motherboard is also know as system board or main board. system board is the communication medium for the entire computer system.                                                               SYSTEM UNIT      Two main components of system unit are as follows;            CPU:                   CPU stands for central processing unit. It is also called processor. It is the brain of the computer. It is the most important of the computer. ...

 Components of Computer Hardware:                              Different components of computer hardware are as follows:           Input Devices:                              The data and instruction given to the computer is called input. A hardware component used to enter data and instruction into computer is called input devices. Different types of input devices are used to input different types of data.               Most commonly used to input devices are as follows:        Keyboard:                         keyboard is used to enter text . It contains alphabetic , number , and other keys for entering different types of data.       Mouse:           ...

   Information Technology:                                           Information Technology is the technology that uses computing. with high-speed communication links to spread information form one place to another. The interconnection of computers enables people to send and receive information. The communication links are also used communicate with different people in the world.             The world has become a global village. due to information technology . It means that people  living in the world know one another as it they are living in a village . It has become possible due to fast communication links. information technology can be transferred form one place to another place easily and quickly.             Information plays an important role in every filed of life. Information can be used to improve th...

           Different between data and information:                                                                   The different between data and information is as follows:                                                                                         Data:   1. Data is the collection of raw facts and figures.   2. Data is used as input in the compute  3. Data is not very meaningful. 4. Data is normally huge in its volume. 5. Data id difficult or even impossible to reproduce. For examples it is very hard to reproduce the data of census if it i...

    Data:              A collection of raw facts and figures is called data. The word raw means that the facts have not been processed to get their exact meaning. Data is given to the computer for processing . Data is collected from different sources . It is collected for different purposes. Data may consist of numbers, characters, symbols or pictures etc.            Examples of Data:                                  Some examples of data are follows:                          . Student fill an admission form when they get admission in college . The form consists   of raw facts about the student. These raw facts are students name father name address etc. The purpose of collecting this data is a to maintain the records of the student during study period i...
