Final answer:
Option B: Logical memory is divided into blocks of the same size called pages, which is a key concept in the management of memory by operating systems, allowing for efficient use and virtual memory features.
Step-by-step explanation:
Logical memory is broken into blocks of the same size called pages. This is a fundamental concept in computer operating systems where the logical memory is managed in a way that each program seems to have its own contiguous working memory. However, in physical memory, these pages may be scattered across different locations.
The term logical memory refers to the abstraction that operating systems provide to applications, ensuring that each process has its own unique address space. Pages allow the operating system to handle memory more efficiently and enable features such as virtual memory, where pages can be swapped in and out of the physical memory to a backing store, often a hard drive, when the physical memory is full.
So, when discussing logical memory subdivision, the correct answer is (b) Pages.
