INTRODUCTION COMPUTER LANGUAGES

A programming language is a machine-readable artificial language designed to express computations that can be performed by a machine, particularly a computer.

THIRD GENERATION PROGRAMMING LANGUAGE

3RD GENERATION... by me..

SECOND GENERATION PROGRAMMING LANGUAGE

FOURTH GENERATION PROGRAMMING LANGUAGE

•  A Fourth-Generation Programming Language(4GL) (1970s-1990)  is a programming language or programming environment designed with a specific purpose in mind, such as the development of commercial business software.

• All 4GLs are designed to reduce :

          -  programming effort,
          -  the time it takes to develop software and
          -  the cost of software development.

FIRST GENERATION PROGRAMMING LANGUAGE

BINARY ARITHMATIC

BINARY ARITHMATIC

And now we are going to learn how addition , subtraction , multiplication and division in binary arithmatic . 

Addition :

Process	Answer	Carry Value
0 + 0	0	0
0 + 1	1	0
1 + 0	1	0
1 + 1	0	1

HMMMMMMM............

THE HEXADECIMAL NUMBER SYSTEM (BASE 16)

TO UNDERSTAND LETS LEARN THIS....

0	1	2	3	4	5	6	7	8	9	10	11	12	13	14	15
0	1	2	3	4	5	6	7	8	9	A	B	C	D	E	F

LETS TRY 

TO MORE UNDERSTAND TRY THIS ALSO..

EVALUATE:
(a)      1342₁₆ +  A490_{16                   (ANSWER =} B7DF₁₆₎
(b)     F4C6₁₆ + E769_{16                   (ANSWER =} 1DC2F₁₆₎
(c)    777.DE₁₆ + AE3.46_{16            (ANSWER =} 125B.24₁₆₎

NUMBER SYSTEM BASE

Most of the numbering system will have a base.The maximum number that can  be represented on the single digit or number is called a base

System	Base	Possible digits
Binary	2	0   1
Octal	8	0   1   2  3  4  5  6  7
Decimal	10	0   1   2  3  4  5  6  7  8  9
Hexadecimal	16	0   1   2  3  4  5  6  7  8  9  A  B  C  D  E  F
