UNIT II

WHAT IS COMPUTING?

TEXT A. What is computing?

1.Suppose you sit down with a pencil and paper and centre your attention on adding a set of figures. You add first all the digits in the right-

hand column, then all the digits in the next column, and so on - until you finally arrive at the answer.1 When you do this, you are computing.

2.When you stop at a street corner, looking first to the left for any coming car, then to the right, to cross the street or to wait on the sidewalk2 - you are computing.

3.When you are walking along a poorly marked path3 in the woods, thinking if you are really on the path or have lost it4 - you are computing.

4.When you are taking in information or data, performing reasonable operations (mathematical or logical operations) on the data, and are producing one or more answers - you are computing.

5.A machine can also do this. It can take in information or data, perform a sequence of reasonable operations on the information which it has received, and put out answers. When it does this, it is computing.

6.A very simple example of a computer is the ordinary business adding machine which prints on paper tape the number entered into its keyboard, and also prints a total when you press the total key. A complex example of a computer is a modern automatic digital computer which in each second can perform more than 100000000 additions, subtractions, multiplications, or divisions.

11

7.A computing machine can take in and store information because the

hardware inside the machine expresses arithmetical and logical relations, such as5 adding or subtracting, comparing or selecting. A computer can also put out information, display the answers when it receives them. Hardware is useless without software which is computer instructions and programs.

8.The modern computers are of three kinds called analog, digital, and hybrid. An analog computer computes by using physical analogs of

numerical measurements. A digital computer computes by using the numbers (digits) and yeses and noes expressed usually in 1's and 0's.6 A hybrid computer is 4 matching which combines some of the properties of digital and analog computers.

Notes:

1.until you finally arrive at the answer - до тех пор, пока вы наконец не подойдете к ответу

2.to cross the street or to wait on the sidewalk - чтобы перейти улицу или подождать на тротуаре

3.a poorly marked path - едва заметная тропинка

4.if you are really on the path or have lost it - действительно ли вы находитесь на тропинке или заблудились

5.such as - такие как

6.yeses and noes expressed usually in 1's and 0's - да и нет,

выраженных обычно единицами и нулями

TEXT C. How much should an educated man know about computers?

Some years ago in the United States of America a discussion on the question what an educated man is was organized. At this discussion one of the definitions of an “educated man” was this:

An educated man:

-is able to read, write, and do arithmetics;

-has a basic knowledge of the history and geography of world and man;

-understands the scientific method, and has an elementary knowledge of at least one science;

-has an elementary knowledge of mathematics and logic, what they are, and how to use them;

-knows at least one other language besides his own well enough to read it and talk a little in it;

-can say what he means in suitable words both speaking and writing;

-is able to listen, knows how to learn, and enjoy learning;

-never forgets that his views and opinions may be wrong, and is always ready to change them on evidence;

-has an elementary knowledge of computers and programming, and some active experience (опыт) with a whole computer is highly desirable.

An educated man of 200 years ago in the United States did not need to know anything about science. The educated man of 35-40 years ago did not need to know anything about computers. But the educated man of today needs to have at least some significant knowledge of science, and at least a little significant knowledge about computers.

The summary knowledge that an educated man should know about computers could be put down on ten sheets of paper, in about 3,000 words.
