Data and instructions 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 is held in ROM? (1-4)

• Data currently in use
• Bootstrap Loader
• Instructions frequently used
• Operating System

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 onperformance? (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 2GHZ to 4GHZ and the numberof cores goes from 2 to 4 – what is the exact effect on the performance of thecomputer? (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

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? (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

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

• Laptops
• Tablets
• PCs
• Washing Machine

Processor don’t do the following (1-4)

• Process Data
• Execute Instructions
• Execute Data
• Operate in Hz

Moore’s Law? (7-9)

• Predicted that the number of transistors on a circuit board would double ever year
• Computers would be capable of thinking and learning for themselves by 2020
• That the number of cores on a processor would double every year
• The performance increase of computers would eventually halt in 2020
