What is Translation Look-Aside Buffer used in paging? answer a)It is a memory that is searched when a page is not found in page table b)It is part of the physical memory to hold process control blocks c)It is a bank of special registers inside the processor d)It is an associative memory that can do parallel frame search in hardware
Q: A digital computer has a memory unit of 64k * 16 and a cache memory of 1k words.

Assuming a 1-KB page size, what are the page numbers and offsets for the following address references (provided as decimal numbers)? 21205 164250 121357 16479315 27253187
Paging: Select all of the following statements that are true. Systems that use paging but do not support inverted page tables maintain at least one separate page table for each process. The frame table is a system-wide data structure. When paging is applied, the selected page size determines which part of a virtual address belongs to the page number and which to the offset. The page size may differ from the frame size. The Translation Look-aside Buffer (TLB) represents a page directory for all pages in the system. Paging is prone to internal fragmentation.
