2 - Models

Question 1

What’s the main principle of Von Neumann’s model?

Answer 1

It’s a machine not for one specific task but to direct a task i.e. it’s a general purpose machine which can take in a set of instructions by using a computer’s memory to store data in binary.

Question 2

What are the 3 main components for the implementation of the INPUT-PROCESS-OUTPUT ?

Answer 2

Hardware, software and the data that is being manipulated.

Question 3

Examples of system software?

Answer 3

• Manage files
• Load programs
• Deliver commands
• Easy of use
• Compilers + assemblers

Question 4

Examples of Application software ?

Answer 4

• Word processing
• Browse web
• DB management

Question 5

4 types of instructions (mnemonics) ?

Answer 5

• logical → AND, OR, XOR
• input / output → in/out
• data transfer/manip. → add/Move
• transfer program control → jl/je/jm (jump or hop around in code)

Question 6

What does a linker do?

Answer 6

It links your binary code to the other bits of code you need for your file to work.

Question 7

Loader?

Answer 7

Loads your program to the memory then runs it → all this to program in HILLs instead of binary.

Question 8

How does a HILL work with an interpreter ?

Answer 8

HILL → Interpreter → analyses → executes (w/o binary) → working out your intentions constantly, but it never translates to binary code.
