1 How do clock speed and word size determine the performance

1. How do clock speed and word size determine the performance of a CPU?

2. which secondary storage devices are appropriate for :

a) Saving data during edit process.

b) Backup data and applications.

c) Distribute data and applications.

d) Transport data and applications.

e) Archive data and applications.

Solution

clock speed:

-->Higher the clock speed the faster the processing ability of the CPU.
-->clock speed is not affected by the word size,since word size is determined by the size
of the data bus.

Wordsize:

--> Bigger the wordsize make code a bit slower.
-->Because 64-bit architecture,pointer are 64-bit words hence data structures which are full
of pointers (lists,tree)tend to use more RAM than what equivalent code does on 32-bit architecture.
-->Common RAM is slow,So Cache is embed by CPU.where more frequently used data is stored.
-->The 64-bit pointers make it harder for the processor to store as many data elements,
hence reduced performance
