1.2.4 programming language

Question 1

What is paradigms?

Answer 1

Paradigm is an approach a programming language takes to define a program and solve problems.

Question 2

What is procedural language?

Answer 2

procedural language is a type of imperative language where programs are broken down into subroutines ( functions and procedures) those subroutines are combined to create solution for problems.

Question 3

What is object oriented program?

Answer 3

a type of imperative language where solution are represented using objects that interact.

Question 4

what is assembly language?

Answer 4

low level programming language that uses mnemonics to represent code?

Question 5

procedural language advantages?

Answer 5

• efficient execution for straight forward programs
• clear flow of control (people can follow the code easily).
• ease implementation on algorithm.

Question 6

procedural language disadvantages?

Answer 6

• not suitable for large programs.
• not suitable for programs with complex state and behaviour (when info changes a lot) .
• difficult to manage and scale programs that grows.

Question 7

object oriented program advantages?

Answer 7

a

Question 8

object oriented program disadvantages?

Answer 8

aaa

Question 9

assembly language advantages?

Answer 9

• similar execution efficient machine code due to it one to one nature.
• it produce very precise, locally optimised efficient code.
• direct access to low system level features as it do not need to go through software interface.

Question 10

assembly language disadvantages?

Answer 10

• machine dependent (code is linked to specific hardware architecture) so the code is not portable.
• programmers who write assembly code efficiently are rare.
• the code is hard to understand, therefore it is difficult to ,modify or maintain.

Question 11

what are the 4 addressing memory?

Answer 11

• immediate addressing.
• direct addressing.
• indirect addressing.
• index addressing.

Question 12

immediate addressing:

Answer 12

the value of the operand it the actual value to be used for the instruction.

Question 13

direct addressing:

Answer 13

the value of the operand gives you the address which hold the value of the data to be used for the instruction.
this is the type used in LMC.

Question 14

indirect addressing:

Answer 14

operand hold the address of the location of the address of the data to be used.
