Question 1

high level language

Answer 1

source code is easy for humans to write but computers need to translate it into machine code

Question 2

low level language

Answer 2

are tricky for humans to read and write but are easier for computers to run

Question 3

features of low level

Answer 3

1) one instruction of code represent one instruction of machine code
2) difficult read, understand and modify
3) no need for a translator
4) control what the cpu does so programs will be more efficient and faster
5) written for one type of machine

Question 4

features of high level

Answer 4

1) one instruction represents many instructions of code
2) written for many different machines
3) easy to read, understand and modify
4) no control over cpu so programs will be less efficient and slow
5) must be translated

Question 5

Answer 5

assemblers, compilers, interpreters

Question 6

what assemblers do

Answer 6

turn assembly language into machine code

Question 7

Answer 7

turn high level language into machine code

Question 8

compilers features

Answer 8

1) translates all code at the same time
2) only needed once
3) returns the errors for the entire program once complete
4) runs quickly but compiling takes longer

Question 9

interpreter features

Answer 9

1) translates one instruction at a time
2) needed every time you run the program
3) return the first error it finds and then stops
4) runs slowely
