B. Fill in the blanks.

1. Machine language is the only language that a computer understands.

2. Assembly language is regarded as the second generation language.

3. A program converted into machine language by a translator is called object code.
(Note: "Assembler" is the translator, not the output.)

4. A/An interpreter converts a high-level language program into machine language line-by-line.

5. Prolog is an 
example of fifth generation language.

C. Write T for True and F for False:

1. A program is a set of instructions.
T

2. The development of computer languages is classified into two categories.
F (It is classified into five generations.)

3. Assembly language consists of binary numbers, 0s and 1s.
F (Assembly uses mnemonic codes, not binary numbers.)

4. Machine language uses simple English words and phrases.
F (It uses binary code — 0s and 1s only.)

5. The ultimate aim of 5GLs is to make computers think and react 
as human beings.
T

D. Answer the following questions (Short Answers):

1. What is a programming language? Define machine language.
Ans:
A programming language is used to give instructions to a computer.
Machine language is the only language computers understand. It uses 0s and 1s.

2. What are the advantages of assembly language?
Ans:
Easier to understand than machine language
Uses short words (mnemonics)
Easy to find and fix mistakes

3. What is the difference between source code and object code?
Ans:
Source code is written by the programmer.
Object code is the computer version made from the source code.

4. What is a translator? How is an interpreter different from a compiler?
Ans:
A translator changes code into machine language.
A compiler changes the whole program at once.
An interpreter changes it one line at a time.

5. What are the features of fifth generation languages?
Ans:
They use Artificial Intelligence (AI)
Help computers think and solve problems
Example: Prolog
