Grade 1 Computer Quiz: Processor

What is the first step in instruction execution?

• Fetching the instruction from memory

• Skipping the instruction

• Storing the instruction in memory

• Executing the instruction

What is the second step in instruction execution?

• Decoding

• Encoding

• Storing

• Fetching

What is the final step in instruction execution?

• Completion of the instruction

• Beginning of the instruction

• Pause of the instruction

• Deletion of the instruction

What is a data path in a processor?

• The data path in a processor is the area where data is stored temporarily before being processed.

• The data path in a processor is the part of the processor that handles input and output operations.

• The data path in a processor is the component that connects the various functional units within the processor, allowing data to flow between them.

• The data path in a processor is the physical path that data takes when moving from one component to another.

How is a data path built in a processor?

• By using only the CPU

• By using software only

• By using only the memory

• By using various components such as registers, multiplexers, ALU, and control signals.

What is the main function of a control unit in a processor?

• Displaying output on the monitor

• Generating power for the processor

• Managing the execution of instructions and coordinating the activities of other units within the processor

• Storing data in the memory

How is a control unit designed in a processor?

• By using mechanical switches and binary code

• Through the use of quantum computing and Python programming

• Using analog circuits and assembly language

• Using digital logic circuits and microcode

What is hardwired control in a processor?

• Use of fixed logic circuits

• Using software to control the processor

• Programming the processor for each task

• Allowing the processor to make its own decisions

What are the advantages of hardwired control?

• No impact on speed, cost, or reliability

• Slower execution, higher cost, and less reliable

• Faster execution, lower cost, and more reliable

• More prone to errors, higher maintenance, and less efficient

What are the disadvantages of hardwired control?

• No impact on performance

• Cost-effective and efficient

• Limited flexibility and difficult to modify

• Easy to modify and highly flexible
