Final answer:
The size of a page in computing is typically a power of 2, which allows for efficient memory management in binary systems. Common sizes include 4 kilobytes, 2 megabytes, among others, depending on the hardware and operating system.
Step-by-step explanation:
The size of a page in the context of computers and technology typically refers to the size of a memory page, which is a fixed-length contiguous block of virtual memory. It is a fundamental unit of data for memory management in a virtual memory system. The correct answer to the question is b) Power of 2. Memory pages are usually sized as powers of two because this allows for easy allocation and management within a binary computing system. For instance, common page sizes are 4 kilobytes (212 bytes), 2 megabytes (221 bytes), or larger, depending on the system architecture and the page size determined by the hardware and operating system.
