What is thrashing?

In the context of compilers, which of the following is/are NOT an intermediate representation of the source program?

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 addressable. The page size is 8k Band 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?

Recall that Belady’s anomaly is that the pages-fault rate may increase as the number of allocated frames increases. Now consider the following statements:

S1: Random page replacement algorithm (where a page chosen at random is replaced) suffers from Belady’s anomaly. S2: LRU page replacement algorithm suffers from Belady’s anomaly .

Which of the following is CORRECT?

Consider the following statements.

• I. Daisy chaining is used to assign priorities in attending interrupts.
• II. When a device raises a vectored interrupt, the CPU does polling to identify the source of interrupt.
• III. In polling,the CPU periodically checks the status bits to know if any device needs its attention.
• IV. During DMA, both the CPU and DMA controller can be bus masters at the same time.

Which of the above statements is/are TRUE ?

Consider two files systems A and B , that use contiguous allocation and linked allocation, respectively. A file of size 100 blocks is already stored in A and also in B. Now, consider inserting a new block in the middle of the file (between 50th and 51st block), whose data is already available in the memory. Assume that there are enough free blocks at the end of the file and that the file control blocks are already in memory. Let the number of disk accesses required to insert a block in the middle of the file in A and B are n_A and , n_B respectively, then the value of n_A + n_B is
