14. Memory Addressing and Bus Size
The chapter explores the concepts of address bus and data bus in computer architecture, focusing on their relationship with memory capacity. It illustrates how the size of the address bus influences the number of addressable memory locations and the implications of different bus sizes on performance and capacity. Additionally, it examines the effects of different organizational structures of memory on the size of address and data buses.

What we have learnt
- The size of the address bus determines how many memory locations can be addressed by a processor.
- Memory size is often described in terms of kilobytes, megabytes, and gigabytes, with binary measurements differing from metric system measurements.
- Data bus size influences how much data can be processed simultaneously by the system.
Key Concepts
- -- Address Bus
- A data bus responsible for transmitting memory addresses from the processor to other components, determining the addressable memory locations.
- -- Data Bus
- A bus that carries data to and from the processor and memory, where its size dictates how many bits can be transferred in one operation.
- -- Memory Capacity
- The total amount of data that can be stored in a memory module, commonly expressed in terms of kilobytes (KB), megabytes (MB), and gigabytes (GB).
