IDEs

Question 1

What are high level languages?

Answer 1

Code is easy to read,understand and modify
Must be translated be for a computer can understand it
Represents many instructions of machine code
Programs will be less memory efficient and slower
Same code will work for many different machines/processors

Question 2

What are low level languages?

Answer 2

Code is very difficult to read,understand and modify
Commands in machine code can be executed without a translator
Programs will be more memory efficient and faster
Only works for one type of machine/processor

Question 3

What do compilers do?

Answer 3

Translates all of source code at the same time to create 1 executable file
Returns a list of errors for the program when compiling is complete
Compiling can take a while but the program runs quickly after

Question 4

What does an interpreter do?

Answer 4

Translates and runs the source code one instruction at a time but doesn’t create an executable file
Needed every time you run a program
Will return the first error it finds and then stop
Programs will run slower because code is translated whilst the program is running

Question 5

What are line numbers?

Answer 5

Allows you to clearly see each new line of code so it’s easy to see errors

Question 6

What is syntax highlighting?

Answer 6

Where the colour of the text changes to show different parts of the program

Question 7

What are error diagnostics?

Answer 7

Helps you find where you have made a mistake by identifying the line number the error has occurred on

Question 8

What are breakpoints?

Answer 8

Set by the programmer so that the IDE stops the program mid way through running

Question 9

What is a run - time environment?

Answer 9

Allows a programmer to test their program whilst it’s running
