15. Name the four leading processor manufacturers.

16. Give a short description of how cache works.

17. What medium does the processor use for one component to communicate with another?

18. What effect does it have when you run multiple processors?



Answer :

Final answer:

This response covers leading processor manufacturers, cache functionality, processor communication medium, and the impact of multiple processors.


Explanation:

Leading Processor Manufacturers:

  1. Intel: A dominant player known for its innovation and market share.
  2. AMD: Known for its competitive processors in the market.
  3. ARM: Specializes in power-efficient processors for mobile devices.
  4. Qualcomm: Known for producing processors for smartphones.

How Cache Works:

Cache memory is a small, high-speed memory unit that stores frequently accessed data to speed up processing. When the processor needs data, it checks the cache first; if the data is there (cache hit), it's retrieved quickly. If not (cache miss), data is fetched from a slower memory.

Medium for Processor Communication:

Processors use system buses to facilitate communication between components. Buses are pathways that transfer data and control signals between the processor, memory, and other peripheral devices.

Effect of Multiple Processors:

Running a system with multiple processors allows for tasks to be divided among them, potentially improving performance and efficiency. However, challenges like task coordination and communication overhead can impact the overall speedup.
