Question 1

What are the features of a compiler

Answer 1

Shows all errors at the end, translates source code into a machine code executable file, translates it all at once

Question 2

What are the features of a interpreter

Answer 2

Shows all errors line by line, translates source code into machine code line by line

Question 3

What are the advantages of a compiler

Answer 3

Faster to run, source code is hidden

Question 4

What are the disadvantages of a compiler

Answer 4

Compiled code is not cross platform, must be recompiled every time it is edited

Question 5

What are the advantages of interpreter

Answer 5

Errors can be spotted quickly

Question 6

What are the disadvantages of interpreter

Answer 6

Source code can be copied, slower, translated every time it is run

Question 7

What are the characteristics of a low level language

Answer 7

Humans cannot understand low level languages, requires the programmer to understand the processors registers and structure, code is not transferable between different processors

Question 8

What are three characteristics of a high level language

Answer 8

Uses English like statements, must be translated to be run and code is transferable between different processors

Question 9

What are examples of low level languages

Answer 9

Machine code and assembly

Question 10

What is assembly language

Answer 10

A language used for programming in embedded systems

Question 11

Why are some programs written in low level language

Answer 11

1. Machine code doesn’t need translation
2. Assembly is fast to translate
3. Faster execution of code
4. Gives the programmer direct control of hardware

Question 12

Why is a compiler needed

Answer 12

To translate the code and pick up errors

Question 13

What is machine code

Answer 13

Code for the cpu to execute, written in binary, does not need to be translated
