What is an address bus?
Q: What is an address bus?
A: An address bus is a computer bus architecture used to transfer data between devices. It connects the CPU with main memory and stores the hardware address of physical memory in binary numbers, allowing the data bus to access memory storage.
Q: How many wires does an address bus have?
A: The number of wires in an address bus determines how many unique memory locations can be addressed. Modern personal computers and Macintoshes typically have up to 36 address lines.
Q: What other elements are part of the system bus architecture?
A: Along with the address bus, the system bus architecture also includes a data bus and control bus.
Q: How much memory can a 32-bit address bus access?
A: A system with a 32-bit address can access 4 gigabytes of memory space.
Q: How much memory can a 64-bit address access?
A: A system with a 64-bit address can access 16 exbibytes of virtually unlimited memory locations when used with a supporting operating system.
Q: What is the purpose of an individual computer's system buses?
A: The purpose of an individual computer's system buses is to connect major components within the computer and decrease costs while enhancing modular integration.
