To further understand the IPO cycle, we can take the example of making

            banana shake.

                     Banana, milk, sugar              put into the mixer             banana shake



            Features of a Computer

            1. Speed:       Computers work at a very high speed and can do billions of jobs
                 per second.


            2. Accuracy:        In addition to being fast, computers are also accurate in giving

                 the results.

            3. Storage:       A computer can store a lot of information which can be used at

                 any time in future.

            4. Diligence:       Unlike human beings, computers are highly consistent. They

                 do not suffer from human traits of boredom and tiredness.

            5. Versatility:      Computers are versatile machines that can perform many

                 tasks and is used in almost all fields.


            Classification of Computers

            Computers can be classified into three major classes based on the mode of
            data representation used.


            Analog Computers

            An analog computer is a form of computer that

            uses  continuous  physical  phenomena  such  as

            electrical, mechanical or hydraulic quantities to

            mode the problem being solved.

            It operates by measuring rather than counting. It uses continuous signals as


            input. Examples:  Digital thermometer, Speedometer etc.

                                                Digital Computers

                                                As its name itself clears, it works with digits 0s and

                                                1s. In other words, digital computers is a counting
                                                device. All the expressions are coded with binary
