Unit 1.1 Systems Architecture MCQs

Processors have a speed measured in (1-4) 

• Hertz 
• Bits 
• Bytes 
• Seconds 

Data and Instructions in use are stored in the: (1-4) 

• Processor 
• Embedded System 
• Hard Disk Drive 
• Main Memory 

Typical processor speed of 2016: (1-4) 

• 16Hz 
• 100MHz 
• 4GHz 
• 300GHz 

What doesn’t affect the performance of the computer (1-4) 

• Clock Speed 
• Number of Cores 
• Cache Size 
• The number of instructions in the program 

If the number of cores goes up from 2 to 4 – what is the exact effect on performance? (1-4) 

• Performance decreases 
• The maximum number of instructions executed per second doubles 
• The maximum number of instructions executed per second quadruples 
• The maximum number of instructions executed per second is halved 

If the processing speed goes up from 1GHZ to 4GHZ – what is the exact effect on the performance of the computer? (1-4) 

• The maximum number of instructions executed per second doubles 
• The maximum number of instructions executed per second quadruples 
• The maximum number of instructions executed per second is halved 
• The maximum number of instructions executed per second is quartered 

If the processing speed goes up from 2GHZ to 4GHZ and the number of cores goes from 2 to 4 – what is the exact effect on the performance of the computer? (5-6) 

• The maximum number of instructions executed per second doubles 
• The maximum number of instructions executed per second quadruples 
• The maximum number of instructions executed per second is halved 
• The maximum number of instructions executed per second is quartered 7 

If the processing speed goes from 1GHZ to 4GHZ and the processor is changed from an 8 core to a dual core processor – what is the exact effect on the performance of the computer? (5-6) 

• The number of instructions executed per second doubles 
• The number of instructions executed per second quadruples 
• The number of instructions executed per second is halved 
• The number of instructions executed per second stays the same 

Firmware in which software and hardware are integrated on a circuit board is often used in what type of system? (5-6) 

• Desktop System 
• Embedded System 
• Operating System 
• Point of Sales System 

Which is an example of an Embedded System: (1-4) 

• Laptops 
• Tablets 
• PCs 
• Washing Machine
