Processors have a speed measured in:

• Seconds

• Bits

• Hertz

• Bytes

• MPH

Data and instructions are stored in the:

• Processor

• Embedded System

• Hard Disk Drive

• Main Memory

• Flash Drive

What doesn't affect the performance of the computer?

• Clock speed

• Number of cores

• Cache size

• The number of instructions in the program

What is the effect on performance if the number of cores goes from 2 to 4?

• Performance decreases

• The max number of instructions executed per second doubles

• The max number of instructions executed per second quadruples

• The max number of instructions executed per second is halved

• The max number of instructions executed stays the same

What is the effect on performance if the processing speed goes up from 1GHz to 4GHz?

• Performance decreases

• The max number of instructions executed per second doubles

• The max number of instructions executed per second quadruples

• The max number of instructions executed per second is halved

• The max number of instructions executed stays the same

What is the effect on performance if the processing speed goes up from 2GHz to 4GHz and cores go from 2 to 4?

• Performance decreases

• The max number of instructions executed per second doubles

• The max number of instructions executed per second quadruples

• The max number of instructions executed per second is halved

• The max number of instructions executed stays the same

If the processing speed goes up from 1GHz to 4GHz and processor is changed from 8 core to dual core- What if the exact effect on the performance?

• Performance decreases

• 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 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 Sale System

• Artificial Intelligence System

Which is an example of an embedded system?

• Laptops

• Tablets

• PCs

• Washing Machine

Processors don't do the following:

• Process Data

• Execute Instructions

• Execute Data

• Operate in Hz

• Perform calculations
