A. write your answer in hexadecimal with or without a leading 0x.
B. if the access causes a page fault, answer with 'pf'.
C. to answer this question, you must find the number of bits used to index pages in physical memory.

Answer 1

Translation of the virtual addresses 0x027C and 0x036B cannot be determined without knowing the page size or number of bits used for indexing. The correct translation would involve the use of VPN, PFN, and potentially a TLB.

Step-by-step explanation:

The question pertains to virtual address translation in the context of computer memory management. When dealing with virtual addresses such as VA = 0x027C and VA = 0x036B, it's essential to know the page size or the number of bits used to index pages in physical memory to perform the translation. Without this information, it is impossible to provide the exact physical address or to determine if the access would cause a page fault (pf). Generally, the process involves extracting the Virtual Page Number (VPN) from the virtual address and using either page tables or a Translation Lookaside Buffer (TLB) to find the corresponding Physical Frame Number (PFN). The TLB index would come into play if a TLB is being used for faster address translation.
