What does the data bus do?
Think about the function of the bus in a computer system.
What is the purpose of the address bus?
Reflect on how computers locate data.
What does the data bus do?
Focus on what the data bus is designed for.
The width of the bus affects its performance.
Consider how much data can move at a time.
A system utilizes a 5-bit address bus and a 16-bit data bus. Calculate the number of memory addresses it can access and the total number of bits it can transfer at once.
Break the problem into two parts: calculate the memory addresses first, then the data transfer.
If a new system is designed with a 4-bit address bus and a 12-bit data bus, what will be the limitations in terms of access and data transfer compared to a system with a 6-bit address bus and an 18-bit data bus?
Compare the capacities in both scenarios to see the differences.
