1.1.5 Factors Affecting the Performance of the CPU

What is the clock speed measured in

• Mph

• Kmph

• Htz

• Newtons

Most Clocks are measured in what capacity of Htz

• KHz

• MHz

• GHz

• THz

A GHz is how many instructions per second?

• 100

• 100 000

• 1 000 000

• 1 000 000 000

The Cache sits between which two components of a Computer System?

• RAM & CPU

• ROM & CPU

• CPU & Mother Board

• RAM & ROM

Why does using Cache make data frequently used by the CPU available much quicker?

• It has a larger capacity than the RAM

• It can decode instructions quicker

• It is more portable than the RAM

• It is closer to the CPU and therefore does not need to fetch instructions from the main memory

In the original Fetch, Decode, Execute cycle how many cores are there in that model?

• 1

• 2

• 3

• 4

A quad core processor has how many cores?

• 1

• 2

• 3

• 4

If i have a duo core processor with a 2GHz clock speed how many billion instructions can i process in a second?

• 2

• 4

• 6

• 8

If i have a quad core processor with a clock speed of 4GHz how many billion instructions can i process in a second?

• 4

• 8

• 12

• 16

Is a computer with quad cores guaranteed to be quicker than a duo core computer?

• No, it depends on whether the computer is programmed to work on multiple cores

• No, it depends on the size of the RAM

• Yes, more cores means it will be quicker no matter what
