Answer:
Possible if hackers are not so intelligent.
Explanation:
Actually, hackers are intelligent
where they will change location code in different places every second. So end-user who is trying to trace it he or she has to use their intelligence to find the exact location of hackers.
Normally hackers will generate different location places and by using decipher it is possible to find the location codes.
Since hackers used encrypted message we need to decrypts the message and find it out and understand the decrypt and encrypt technology used by hackers.
It is possible to by using decipher to get uncovered locations
Answer:
b. P2 requests drive 2 and gets it.
Explanation:
Two users from the local board of education are each running a program (P1 and P2), and both programs will eventually need two DVD drives to copy files from one disc to another.

The BIOS feature that enables a hard drive to read or write several sectors at a time is called IDE block mode
Explanation:
IDE block mode setting speeds up IDE drivers when enabled by allowing multiple sectors to read or write operations. This BIOS feature rushes up hard disk drive passage by transferring many divisions of data per interrupt rather than using the normal single-sector transfer mode.
This mode of transfer is known as block transfers. When block transfers are enabled, depends on the IDE controller, nearly 64 KB of data can be transferred per interrupt.
