- 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 hardwareThe effective access time in a virtual memory system depends on the TLB hit rate but does not depend on whether the page table contains a valid translation for the page. O True O FalseIf a program has 471 bytes and will be loaded into page frames of 126 bytes each, assuming the job begins loading at the first page (Page 0) in memory, and the instruction to be used is at byte 132, answer the following questions: a. How many pages are needed to store the entire job? b. Compute the page number and exact displacement for each of the byte addresses where the desired data is stored.

It.?5. Ifa program has 956 bytes and will be loaded into page frames of 150 bytes each, and the instruction to be used is at byte 332, answerthe following questions: a. How many pages are needed to store the entire job? b. Compute the page numberand exact displacement for each of the byte addresses where the data is stored. (Remember that page numbering starts at zero).
- Write a service routine which resets all elements of an array that resides in memory location from A000 H to A0FF H with DS equal to 0000 H. The service routine address is CS:IP where CS is 2000 H and IP is 0100H. Assume the interrupt type that is called is 50 (x8086- nano)The FIQ interrupt methods are required to establish a connection and succession at the designated offset within the Interrupt Vector Table.

The page table of p1 begins at address 4. The page table of p2 begins at address 12. · A dash denotes a nonexistent page. The sign bit serves as the present bit. Thus a positive number in a page table is the address of a resident page and a negative number denotes a non-resident page. Both processes reference the virtual addresses: 0, 1,4, 5, 8, 10, 12, 15. Fill in the missing entries in the following table. In the "Access by p1" and "Access by p2" columns, enter one of the following: • If the address being referenced is in memory, enter the value found in the associated memory location. • If the memory reference will cause a page fault, enter "Page fault" • If the memory reference is illegal, enter "Error" Virtual Address…
