Fill in the missing term:

The Central _________________ Unit

The ​ (a)   the clock speed the ​ (b)   fetch-decode-execute cycles it can perform per ​ (c)   .

• higher
• more
• second
• lower
• less
• minute
• hour

How can we choose a better performing CPU?

• ...stored for quick access for the CPU.

• The higher the clock speed the more instructions...

• ...can be processed at the same time.

• The more cores in the CPU, the more instructions...

• ...can be processed per second.

• The larger the cache size the more instructions...
