- How many disk accesses are needed to bring byte i of a file into memory when the file is stored using contiguous allocation? Assume only the file’s FCB is in memory , block pointers require 32 bits , and that blocks hold 4096 bytes each.
- 3 accesses
- 1 + [ i/4096] accesses
- [i/4096 accesses
- 2 accesses
- 1 access
Homework Answers
Since the allocation used is contiguous method, all the blocks are stored contiguously. Hence a particular byte is accessed in 1 disk access.

Consider a file system on a disk that has both logical and physical block sizes of 512 bytes. Assume that the information about each file is already in memory. For each of the three allocation strategies (contiguous, linked, and indexed), answer these questions: If we are currently at logical block 5 (the last block accessed was blocked 4) and want to access logical block 15, how many physical blocks must be read from the disk?

Consider an empty 1 Gbyte disk with the block size of 4096
bytes. When the disk is formatted blocks 0 is occupied for
system-related information. The system always allocated free blocks
starting st the lowest numbered block, and it uses non-contiguous
allocation.

Consider a disk with block size = 4096 bytes. A block pointer is 6 bytes and a record pointer is 8 bytes long. A file has 100,000 records of fixed length. Each record has the following fields and byte size: Name (30), Ssn (9), Dept (9), Address (40), Phone (10), Bdate (8), Sex (1), Job (4) and Salary (4). An additional byte is used as a deletion marked. a. Calculate the record size R in bytes b. Calculate the blocking...

A UNIX-type file-system uses a disk block size of 1KB, 128 byte inodes, and 32 bit disk addresses. If the inode contains 64 bytes of data, 8 direct, 1 indirect, 1 double-indirect, and 1 triple- indirect blocks, apart from other file information. How many disk blocks would be required for storing files of sizes (a) 1 byte (b) 1024 bytes (c) 64 KB (d) 1MB ?

We know that there are different disk allocation methods that help the operating system decide how disk blocks are allocated for files. In the contiguous disk allocation method, each file occupies a set of consecutive addresses on the disk. While this makes file allocation easier, an increase in the file size means that it has to be assigned elsewhere on the disk. The linked disk allocation method requires including a pointer in the current file, which points to the location...

1 Mark Question Two Consider a file system on a disk that has both logical and physical block sizes of 512 tebytes. Assume that the information about each file is already in memory. For each of the three allocation strategies (contiguous, linked, and indexed), answer these at questions: a. How is the logical-to-physical address mapping accomplished in this system? (For the indexed allocation, assume that a file is always less than 512 blocks long.) b. If we are currently at...
