28.2.3. Overview of Three Bus Architecture

Try these first

1. 1.

   What is a bus in computer architecture?

   Hint

   Think about how components exchange information.

2. 2.

   How does a three bus architecture improve operations?

   Hint

   Consider more buses meaning more pathways.

3. 3.

   Which of the following describes a three bus architecture?

   • It has only one data bus
   • It can carry data in parallel
   • It is slower than single bus

   Hint

   Consider how many paths data can take.

4. 4.

   True or False: In a single bus architecture, the program counter can update in one step.

   • True
   • False

   Hint

   Think about the number of steps involved.

5. 5.

   Assess the impact of a three bus architecture on a system designed for real-time processing. How might it influence performance?

   Hint

   Consider how faster data transfer affects response times.

6. 6.

   Provide a theoretical example where a single bus architecture might outperform a three bus architecture.

   Hint

   Think about scenarios where less complexity is advantageous.
