Computer Fundamental Character satiric of computer

1. Character satiric of computer?

Answer: speed. A computer is a very fast device. It can perform in a few second the amount of worked that a human being does an entire year. if he worked day and night and did nothing else. To put it on a different manner, a computer dose on one minute what world take a man his entire lifetime. While talking about the speed of a computer , we do not talk in terms of seconds or even milliseconds (10^-3), the nanoseconds (10^-9 ), and even the picoseconds (10^-12), the . A powerful computer is capable of performing about 3 to 4 million simple arithmetic operations per second.

                  Accuracy. 
                 The accuracy of a computer consistently high and the degree if accuracy of a                 particular computer depends upon its design but for a particular computer each             and every calculation is performed with the same accuracy. Errors can occur in             a computer but these are mainly due to human rather than technological                         weaknesses that is due to imprecise thinking by the programmer (a person who             writes instructions for a computer to solve a particular problem ) or due to                        inaccurate data.

1.       Diligence.

       Unlike human beiges, a computer is free from monotony tiredness, lack of concentration, etc. and hence can work for hours together without creation any error and without grumbling due to this property computers obviously score over human beings in doing routine type of jobs which require great accuracy. If ten million calculations have to be performed, a computer will perform the ten million calculations with exactly the same accuracy and speed as the first one.

2.       Versatility.

Versatility is one of the most wonderful thing about the computer one moment it is preparing the results of particular examination the next moment is busy

Preparing electricity bill and in between it may be helping an office secretary to trace an important letter in seconds. All that is required to change its talent is to slip n a new program (a sequence of instructions for the computer) into it briefly; a computer is capable of performing almost any task provided that the task can be reduced to a series of logic steps.

Power of remembering:

 As a human being acquires ne w knowledge, the brain subconsciously selects what it feels

                To be important and worth retaining in its memory and relegates un important details to the                back f the mind or just forgets them. With computers, this is not the case. A computer can                    store and recall any amount of information because of its secondary storage (a type of                        detachable memory) capability. Every piece of information can be retained as long as desired              by the user and can be recalled as and when required. Even after several years. The  it was                  fed to the computer. A computer forgets or loses. Certain information only when it is asked to            do so . So it is entirely up to the user to make a computer retain or forger particular                              information. 

2. briefly describe second Generation of computer?

Answer:  second generation (1955-1964)

The transistor, a smaller and more reliable successor to the vacuum tube, was invented in 1947. However, computers that used transistors were not produced in quantity until over a decade later. The second generation emerged with transistors being the brain of the computer with both the first and the second generation computer the basic component was discrete or separate entity. The many thousands of individual components had to be assembled by hand not functioning circuits. The manual assembly of individual components and the cost of labor involved at this assembly stage made the commercial production of these computers difficult and costly

Advantage

• 1.       smaller in size as compared to first generation computers
• 2.       more reliable
• 3.       less heat generated
• 4.       These computers were able to reduce computational times from milliseconds to microseconds.
• 5.       Less prone to hardware failures
• 6.       Better portability
• 7.       Wider commercial use

Disadvantage

1.       Air conditioning required

2.       Frequent maintenance required

3.       Manual assembly of individual components into a functioning unit was required

4.       Commercial production was difficult and costly

3. Describe about the ENIAC ?

 Answer:  The electronic numerical integrator An calculator (ENIAC) was the first all electronic computer. It was constructed at the more school of engineering of the University of Pennsylvania U.S.A By design team led by professors J. prosper Eckert and John mannishly.
