Total questions: 20
Worksheet time: 13mins
In Von Neumann architecture, where are programs and data stored?
In separate memories
In the same memory
In the cloud
On external drives
What is the key idea of the Von Neumann architecture called?
Cloud computing
Distributed processing
Stored program concept
Parallel processing
What is one advantage of storing programs and data in the same memory?
It makes computers slower
It makes computers more expensive
It makes computers simpler and cheaper
It requires more memory types
What is a benefit of using the same space for both data and instructions?
It makes the computer less efficient
It helps run different tasks easily
It requires more hardware
It limits the computer's capabilities
Which component in Von Neumann Architecture acts as pathways for data?
Main Memory (RAM)
CPU
Buses
Clock
What does the Control Unit (CU) do within the CPU?
Performs mathematical calculations
Directs the flow of data
Stores data temporarily
Carries out logical operations
Which component of the CPU tells the computer's memory and devices how to respond to instructions?
Registers
Arithmetic Logic Unit (ALU)
Control Unit (CU)
Hard Drive
Which of the following statements is true about CPU clocks?
They only synchronize input/output operations
They are not related to the FDE cycle
They synchronize all actions in the CPU
They only affect memory access speed
What happens when the clock speed is increased?
The CPU processes fewer instructions
The CPU generates less heat
The CPU processes more instructions
The CPU uses less power
Which type of bus sends control signals to coordinate operations?
Address Bus
Data Bus
Control Bus
Signal Bus
What is the role of the width of a bus?
Determines the speed of data transfer
Determines how many memory locations can be accessed
Determines the size of the CPU
Determines the power usage
What bus does the CPU use to send a signal to initiate a read operation from RAM?
Control bus
Data bus
Address bus
System bus
What bus is used when an interrupt signal is sent from an I/O device to the CPU?
Control bus
Data bus
Address bus
System bus
What is the purpose of the Fetch-Decode-Execute cycle?
To store data
To process instructions
To send signals
To halt operations
Complete the computing term: Fetch Decode (a) Cycle
Small memory cells inside the CPU that temporarily store data and interim results during processing are known as (a)
What component of the CPU carries out logical operations (e.g. comparing values)?
ALU
Clock
Registers
Every tick of the (a) starts the next step in the FDE cycle.
Clock speed is measured in (a) , which means cycles per second.
Higher clock speeds can make the computer work faster, but also produce more (a) .
