Final answer:
A logical address is a virtual address used by the operating system to reference a memory location, while a physical address represents the actual physical location of data in memory. Minimizing swapping time when a process is allocated the CPU involves efficient memory management techniques like virtual memory and page replacement algorithms.
Step-by-step explanation:
The difference between a logical address and a physical address lies in their purpose and representation.
A logical address is the virtual address used by the operating system to reference a memory location. It provides a way for processes to interact with memory without knowing the physical layout of memory. The logical address space is typically divided into pages or segments for efficient management.
A physical address, on the other hand, represents the actual physical location of data in memory. It refers to the specific location of a memory cell, such as a byte or a word. The physical address space corresponds to the actual physical memory present in the system.
In terms of minimizing swapping time when a process is allocated the CPU, it is crucial to have an efficient memory management system. This involves techniques like virtual memory and page replacement algorithms, which allow for efficient allocation and movement of data between the main memory and secondary storage. By using logical addresses, the operating system can map them to physical addresses dynamically, optimizing the swapping process and reducing time overhead.
