An address bus is a critical component in a computer architecture that carries memory addresses from the processor to other components, allowing the CPU to access specific memory locations. The width of the address bus determines the maximum addressing capability of the system, directly influencing how much memory can be accessed by the processor.

Memory capacity refers to the amount of information that can be stored in a memory system, whether biological or artificial, and is influenced by factors such as encoding, storage, and retrieval processes. In computing, it is often measured in bytes, while in human cognition, it involves complex interactions between short-term and long-term memory systems.
