1.
Computing pioneer from Hungary who gave his name to a computer architecture that uses stored programs. Instructions are fetched, decoded and executed one at a time.
a)
Von Neumann
b)
Bus
c)
Architecture
d)
Central Processing Unit
e)
Stored program
2.
The phase of the instruction cycle that retrieves an instruction from main memory
a)
Fetch
b)
Von Neumann
c)
Bus
d)
Architecture
e)
Central Processing Unit
3.
This phase of the instruction cycle determines what task the CPU must perform
a)
Decode
b)
Fetch
c)
Von Neumann
d)
Bus
e)
Architecture
4.
The phase of the instruction cycle where the task is carried out, which could be an arithmetic, shift, logic or memory operation
a)
Execute
b)
Decode
c)
Fetch
d)
Von Neumann
e)
Bus
5.
Also known as the instruction cycle, the complete process of retrieving an instruction from store, decoding it and carrying it out
a)
Fetch-Execute Cycle
b)
Execute
c)
Decode
d)
Fetch
e)
Von Neumann
6.
A single operation, one of these is executed each time the CPU performs the fetch-execute cycle
a)
Instruction
b)
Fetch-Execute Cycle
c)
Execute
d)
Decode
e)
Fetch
7.
Also known as RAM or Primary Storage, this is where data and instructions are stored in the Von Neumann architecture
a)
Main memory
b)
Instruction
c)
Fetch-Execute Cycle
d)
Execute
e)
Decode
8.
Computers take input, and produce output. This is what happens in between, which needs a CPU
a)
Process
b)
Main memory
c)
Instruction
d)
Fetch-Execute Cycle
e)
Execute
9.
Von Neumann invented this concept, it means keeping the instructions in memory instead of inputting them each time through switches or paper tape
a)
Stored program
b)
Process
c)
Main memory
d)
Instruction
e)
Fetch-Execute Cycle
10.
This component repeatedly fetches, decodes and executes instructions. Often abbreviated to CPU
a)
Central Processing Unit
b)
Stored program
c)
Process
d)
Main memory
e)
Instruction
11.
The design of a computer, including the way its components are organised and the rules that male them work together. Von Neumann invented a type of this
a)
Architecture
b)
Central Processing Unit
c)
Stored program
d)
Process
e)
Main memory
12.
A collection of wires through which data or signals are transmitted between the CPU and other components
a)
Bus
b)
Architecture
c)
Central Processing Unit
d)
Stored program
e)
Process
Reset
