Programme is a sequence of instructions written in a proper language through which the computer can understand and solve the problem given to it. It is the method by which the whole computing process is directed and controlled. Preparing a programme for the computer is known as “programming”.
A programme should be recorded on a proper medium which the computer can process. Usually punched cards are used for this purpose. Each computer can understand one language which is known as “machine language”.
Machine language contains use of numeral codes and each computer has its own machine language. It is very difficult to write a programme in this language. To obliterate this difficulty, some other languages have been developed.
These can be grouped into following two categories:
A machine oriented language can only be used on a computer for which it has been designed. This language contains alphabetic codes, which are known as unmemoric codes. So, it is easier to remember unmemoric codes than numeric codes and it is easier to write a programme in this language.
A machine oriented language is oriented to a particular computer and not oriented to a particular problem. To avoid this difficulty, problem oriented languages have been developed. It is easier to write programmes in these languages. These are also known as high level languages.
These languages are also to be translated before execution. The programme used for translation in this case is known as ‘computer programme’. It is a standard programme written and supplied by the computer manufacturers for doing translation job.
It is a programme which translates programme in a language other than the machine code of a specific computer into instructions which a computer can obey. Because of this, language barrier between men and computer is broken down.
ADVERTISEMENTS:
Some problem oriented languages are:
FORTRAN (Formula Translation)
ALGOL (Algorithmic Language)
COBOL (Common Business Oriented Language)
ADVERTISEMENTS:
BASIC (Beginner’s All-purpose Symbolic Instruction Code)
Out of all FORTRAN is the most common programming language available on almost all the computer systems.
Essay # 2. Standard Programmes:
The computer manufacturers, as a matter of sales strategy, supply readymade programmes without additional charge which are common to many users. Such programmes are known as standard programmes because they are designed in a standard wav for applications and can be used by many users.
ADVERTISEMENTS:
Such programmes are becoming popular because of increased co-operation between the programme designers and the prospective users.
Essay # 3. Debugging of Computer Programme:
Very few programmes are accurate in the first instance. Usually there are errors in a programme. The removing of these errors (i.e., bugs) is known as debugging of a programme. There are two types of errors that a programmer has to deal with in a programme. These errors are known as syntax error and logical error.
Syntax error is the error that violates the grammar of the computer language in which the programme has been written. Logical error is that type of error which violates the logic of doing certain-thing. For example, an item which should have been added might have been deducted.
Essay # 4. Binary Code System:
It is a method of expressing numerical value by numbering system based on two numbers. In this system, there are only two digits, 1 and 0. Zero is emergency digit and it is to be used when stock is exhausted. Use of zero is very frequent because the stock of one digit exhausts very quickly.
Development of numbers in this system is as follows:
Number and Theory of Development
Thus, in a binary code system the data is represented in terms of 0’s and l’s and this system is used to represent data on a computer.
Essay # 5. Decimal System:
In this system there are ten digits— 1, 2, 3, 4, 5, 6, 7, 8, 9 and 0. The tenth digit zero is called emergency digit and is to be used when all other digits from 1 to 9 are exhausted. The zero digit is to be used in a systematic way i.e. first with first digit (10), then with second digit (20) and then with third digit (30) and so on and so forth. Thus, the base of decimal system is 10.
Scanners:
Scanners are devices which allow direct data entry into the computer without doing any manual data entry.

Flow Chart:
A flow chart illustrates the sequence of operations to be performed to arrive at the solution of a problem. The operating instructions are placed in boxes which are connected by arrows to indicate the order of execution. These charts are an aid to writing programmes and are easier to understand at a glance than a narrative description. A flow charts also known as a flow diagram.
While preparing flow charts, certain conventions have come into use as given below:

A flow chart for the computation of Economic Order Quantity (i.e., EOQ) may be as follows:
