List of top Computer Science & Information Technology Questions on Memory Management and Virtual Memory

Assume that in a certain computer, the virtual addresses are 64 bits long and the physical addresses are 48 bits long. The memory is word addressible. The page size is 8 kB and the word size is 4 bytes. The Translation Look-aside Buffer (TLB) in the address translation path has 128 valid entries. At most how many distinct virtual addresses can be translated without any TLB miss?
In a page segmented system, a virtual address consists of 32 bits of which 12 bits are a displacement, 11 bits are segment number, and 9 bits are page number. What is the page size?
