Answer 1

The system bus is like a communication line that the processor use to talk to the rest of the system. Faster is not always better, it depends on the situation.

Cache memory on processors is just like other memory only a lot faster. When the processor needs recent information it will look in cache first before going to system memory and finally to the harddrive. Obviously more cache memory will store more information and thus keep the processor from going to system memory or disk for data to often.

Answer 2

A system bus is like a Bus Station as the buses go to their various destinations from bus station so does the information on your computer it travels along circuits to its destination

A cache is like when explorers leave a cache of food etc so they have it when they return it is a small fixed amount that stores information so it can be retrieved quickly when needed
