Programming Languages

Question 1

Define High-Level Language

Answer 1

user-oriented

Question 2

Define Low-Level Language

Answer 2

• machine-oriented
• processor defined
• no built-in functions
• can access specific registers

Question 3

Define Imperative High Level languages

Answer 3

• Procedural

- List of Instructions

Question 4

Define Declarative Languages

Answer 4

• Defines problem to be solved

e. g. SQL, Haskell

Question 5

Define OOP

Answer 5

• Objects and Classes

- Define data and instructions to manipulate the data

Question 6

Define opcode

Answer 6

specifies which operation the processor should perform

Question 7

Define operand

Answer 7

• value

- can be actual piece of data or memory reference

Question 8

Advantages of High-Level

Answer 8

• Much easier to write
• Portable
• Libraries

Question 9

Advantages of Low-Level

Answer 9

• High needs to be translated into machine code
• Can use specific registers
• Better for limited memory (resources used efficiently)

Question 10

Disadvantages of Low-Level

Answer 10

• More Difficult
• Not Portable (Machine/Instruction Set Specific)
• No Libraries

Question 11

Define Processor Instruction Set

Answer 11

• Defines instructions that can work with a specific processor
• Word Size = number of bits a processor handles as a single unit

Question 12

Define Addressing Mode

Answer 12

• Part of opcode
• Specifies the way the operand will be interpreted
• Value or Memory location

Question 13

Define Immediate Addressing

Answer 13

-Actual Value

Question 14

Define Direct Addressing

Answer 14

-Memory Address

D

Question 15

Define Indirect Addressing

Answer 15

-Address which holds address to where data is stored
