?

Accepted Answer

⚹ The maximum amount of memory a computer can have is directly related to the number of wires in the address bus because each wire can carry one bit of binary information, representing two states: 0 or 1 ⚹ ⚹ With 20 wires in the address bus, the number of unique addresses that can be generated is $2^{20}$ ⚹ ⚹ Each unique address corresponds to a memory location, and if we assume that each memory location holds one byte, then the maximum amount of memory is $2^{20}$ bytes ⚹ ⚹ To convert this into a more understandable unit, we can express $2^{20}$ bytes as megabytes (MB), where 1 MB is equal to $2^{20}$ bytes ⚹ ⚹ Therefore, the maximum amount of memory that this computer can have is 1 MB ⚹
