1.1 Systems Architecture MCQs

Processors have a speed measured in....

• Hertz
• Bits
• Bytes
• Seconds

Data and Instructions in use are stored in the:...

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

Typical processor speed of 2016:...

• 16Hz
• 100Hz
• 4GHz
• 300GHz

What doesn’t affect the performance of the computer?...

• 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?...

• 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?

• 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?

• 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 from 1GHZ to 4GHZ and the processor ischanged from an 8 core to a dual core processor – what is the exact effect on theperformance of the computer?

• 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?

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

Which is an example of an Embedded System:

• Laptops
• Tablets
• PCs
• Washing Machine
