2.5 Translators and Facilitators of Language

Question 1

What is a high-level language?

Answer 1

A programming language that enables the development of a program in a much more user-friendly programming context

Question 2

What are the advantages of high-level languages?

Answer 2

Easy to read and understand

Code will work on many different computers and processors

Question 3

What does each instruction in a high-level code represent?

Answer 3

It represents many machine code instructions

Question 4

What are the disadvantages of high-level language?

Answer 4

Code has to be converted into machine code for the computer to understand so, therefore, is less efficient
Programs will be less memory efficient as there is no control over what the CPU does

Question 5

What are low-level languages?

Answer 5

Code that can be understood by the computer
Machine code (Binary)
Assembly language

Question 6

What are the advantages of low-level languages?

Answer 6

Programs are more memory efficient as you control what the CPU does
Machine code can be executed without translators

Question 7

What are the disadvantages of low-level languages?

Answer 7

Very difficult to read and understand

Question 8

What does each instruction in low-level language represent?

Answer 8

One particular instruction of machine code

Question 9

What is the purpose of Assemblers?

Answer 9

Turns assembly language into machine code

Question 10

What is the purpose of Compilers?

Answer 10

Translate all of the code in one go

Question 11

Do compilers create an executable file?

Answer 11

Yes

Question 12

When does the Compiler give a list of errors?

Answer 12

At the end of the program

Question 13

What is the purpose of interpreters?

Answer 13

Transaltes the code line by line

Question 14

Do Interpreters create an executable file?

Answer 14

No

Question 15

When does the Interpreter give a list of errors?

Answer 15

Interpreter will stop after each error

Helps debugging

Question 16

What is an IDE?

Answer 16

Integrated design environment

Question 17

How are Editors a useful feature in an IDE?

Answer 17

Includes line numbers and colour coding for different features of the code
Helpful for tracking and fixing errors

Question 18

How can a Run-Time Environment be a useful feature in an IDE?

Answer 18

Outputs the window

Stimulating different devices the program can run on

Question 19

How can Error Diagnostics - debugging tool - be a useful feature in an IDE?

Answer 19

Helps to find and solve errors using diagnostic tools

Question 20

How can translators be a useful feature in an IDE?

Answer 20

Translates the code into machine code so the computer can understand it

Question 21

How are Breakpoints a useful feature in an IDE?

Answer 21

It can gather information by stopping the program on certain lines

Question 22

What are the advantages and disadvantages of a compiler?

Answer 22

Code is usually optimised
Original source code is kept a secret
No need for translation software at run-time

Code needs to be recompiled when the code is changed
Program will not run with syntax errors

Question 23

What are the advantages and disadvantages of interpreters?

Answer 23

Easy to write source code because program will always run
Code does not need to be recompiled
Makes it very easy for beginner programmers to learn to write code

Source code is needed
Code is not optimised
