Assume that the maximum capacity of a file system space is 8TB (1TB = 240 bytes), and the disk block size is 2KB. The file control block (FCB) contains an index table of 512 bytes. Answer the following questions:
(2) [4 MARKS] Suppose that the index table area adopts the following structure: the first 8 bytes (0 ~ 7 ) use <start block number, number of blocks> to represent the pre-allocated continuous storage space during file creation, in which the start block number accounts for 6 bytes, and the number of blocks accounts for 2 bytes; the remaining 504 bytes use the direct index structure, and one index entry accounts for 6 bytes. What is the maximum length of a single file that can be supported by this scheme? In order to maximize the length of a single file, what values of the start block number and number of blocks should be set at?

Assume that the maximum capacity of a file system space is 8TB
(1TB = 240 bytes), and the disk block size is 2KB. The
file control block (FCB) contains an index table of 512 bytes.
Answer the following questions:
(1) [4 MARKS] Suppose that the index table only adopts the
direct index structure, and stores the disk block numbers occupied
by the file. How many bytes are required for each index table entry
to represent a disk block number? What...

Assume a computer with a cache that holds 64 bytes and has a
block size of 32 bytes. Direct address mapping is used and from the
beginning the cache is empty. The following program sequence is
executed:
for (col = 0; col < 2; col++) {
for (row = 0; row < 4; row++)
A[row][col] = B[row] * C[col]; }
Assume that for the variables row and col registers are
used.
The matrix A consists of 4 rows and 4...
