A file is executing in sequence, when line number 10 is going to be execute then an interrupt occur, Briefly explain the mechanism of interrupt handling when you are using a interrupt driven I/O module is there any disadvantage of this scheme? b) Consider a magnetic disk drive with, 5012 tracks, and 76 sectors Per track. Sector size is 3.5 kB. The average seek time is 6 ms, the trackTo-track access time is .5 ms, and the drive rotates at 300 rps. Successive tracks can be read without head movement. a. What is the disk capacity? b. What is the average access time? Assume this file is stored in successive sectors And tracks starting at sector 0, track 0, c. Estimate the time required to transfer a 2-MB file. d. What is the access time if file is stored at random sectors in random tacks?

Attempt all questions and all question carry equal marks. Q1: a) A file is executing in sequence, when line number 10 is going to be execute then an interrupt occur, Briefly explain the mechanism of interrupt handling when you are using a interrupt driven I/O module is there any disadvantage of this scheme? b) Consider a magnetic disk drive with, 5012 tracks, and 76 sectors Per track. Sector size is 3.5 kB. The average seek time is 6 ms, the track- To-track access time is .5 ms, and the drive rotates at 300 rps. Successive tracks can be read without head movement. a. What is the disk capacity? b. What is the average access time? Assume this file is stored in successive sectors And tracks starting at sector 0, track 0, c. Estimate the time required to transfer a 2-MB file. d. What is the access time if file is stored at random sectors in random tacks? Q2 a) Perform the both algo for Division on the following :  7/0  0//7 (b) Briefly Explain displacement addressing scheme with the help of any suitable example Q3 (a) In computer instruction are categorized into D/F groups or Types. Point out the advantages and especially the disadvantages (is there any) of this scheme. (b) There are three main hazards in the way of pipelining, resource hazard, data hazard and branch hazard. Take an example of your own and briefly explain all three hazards in one single, case by constructing the diagram of pipelining with sic stages.
