J276 1.1 System Architecture

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
• 100MHz
• 4GHz
• 300GHz

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

What doesn’t affect the performance of the computer?

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

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

• 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 2GHZ to 4GHZ and the number of cores goes from 2 to 4 – what is the exact effect on the performance of the computer?

• 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 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?

• The number of instructions executed per second stays the same
• 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

Firmware in which software and hardware are integrated on a circuitboard 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:

• Washing Machine
• PCs
• Tablets
• Laptops
