Final answer:
Each byte of memory is indeed assigned a unique address in a computer system, allowing the CPU to effectively access and manage memory.
Step-by-step explanation:
The statement that each byte of memory is assigned to a unique address is true. In computer systems, memory management is a fundamental concept in which each byte of the main memory (RAM) is associated with a unique address. This addressing allows the CPU to access and manage memory efficiently. An address space in a computer is a range of discrete addresses, each of which may correspond to a physical or virtual storage location, and these addresses serve as a way to uniquely identify each byte of memory.
For example, consider a 32-bit system, which has a 32-bit address bus. This system can address up to 232 bytes (or 4 GB) of RAM, with each byte of that RAM having a unique address. When a program runs, it accesses memory by referring to these unique addresses to read data from or write data to particular memory locations.
