Translators

Question 1

What are the 2 main translators

Answer 1

Compiler

Interpreter

Question 2

What does a compiler do

Answer 2

translates all the code into machine code in one go, producing an executable file which can be run.

Question 3

Pros and cons of a compiler

Answer 3

Much faster to run than an interpreter

The source code must be re-compiled every time the programmer changes the program.

Question 4

What is an interpreter

Answer 4

translates the code one line at a time, into machine code during program execution.

Question 5

Pros and cons of an intepreter

Answer 5

Much more effective to debug for individual errors

interpreter code is really slow compared to compiled code.

Question 6

What is a high level language

Answer 6

easier to write and program as no expertise is needed (closest to human language and understanding)

Question 7

What are some examples of a high level language

Answer 7

Python,java

Question 8

Advantages of high level language

Answer 8

􏰁 easier to program and modify
􏰁 programs can be written much faster
􏰁 code can be debugged easily
􏰁 code is portable across multiple platforms

Question 9

Dis of high level language

Answer 9

􏰁 requires more memory than low level languages
􏰁 translation takes longer and less control over
hardware

Question 10

What is a low level language

Answer 10

programs written related to specific computer hardware and architecture

Question 11

Examples of low level language

Answer 11

Assembely language, machine code

Question 12

Pros of low level lang

Answer 12

􏰁 assembly language uses English like statements

􏰁 translated programs require less memory

Question 13

Cons of low level language

Answer 13

􏰁 machine code is difficult to understand and takes longer time to write programs
􏰁 code is machine dependant (not portable)
