Summative Assessment

A.    Multiple choice questions:

1.    Source Program

2.    Interpreter

3.    Object Program

4.    John W. Tukey

B.     Answer the following questions:

1.    This is the only language that computer understands. It is expressed in the form of 0 and 1.It is very difficult to understand this language.It is machine dependent.It is considered as Low Level language(LLL).

2.    Assembly language uses ‘mnemonics codes’ or symbols in place of 0 and 1. Since a computer understands only the machine language so,translators programs called Assemblers are used to convert the assembly language program into machine language. It is also a LLL(Low Level Language).

3.    The features of high level language are:

                   i.            Simple and user friendly

                ii.            Machine Independent language

              iii.            Easy to learn and use

4.    Difference between compiler and interpreter is:

No	Compiler	Interpreter
1	Compiler Takes Entire program as input	Interpreter Takes Single instruction as input .
2	Intermediate Object Code is Generated	No Intermediate Object Code is Generated
3	Conditional Control Statements are Executes faster	Conditional Control Statements are Executes slower
4	Program need not be compiled every time	Every time higher level program is converted into lower level program
5	Errors are displayed after entire program is checked	Errors are displayed for every instruction interpreted (if any)
6	Example : C Compiler	Example : BASIC
