Computer Architectures and Memory Systems Quiz

The main difference between the Harvard and von Neumann architectures is the way they handle memory. In the von Neumann architecture, the main memory is used for both data and instructions, while in the Harvard architecture, separate memory spaces are used for instructions and data.

Cache memory in modern computers is used to store frequently accessed data and instructions for faster access. It helps reduce the time taken to fetch data from the main memory, improving overall system performance.

Having multiple buses for data transmission in advanced digital signal processors allows for simultaneous read and write operations, improving data transfer efficiency and overall system performance.
