Fill in the missing step in the following deadlock situation. 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.

Complete Question:

Fill in the missing step in the following deadlock situation. 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. Only two DVD-R drives are available and they’re allocated on an “as requested” basis. Soon the following sequence transpires:

1. P1 requests drive 1 and gets it.

2.

3. P1 requests drive 2 but is blocked.

4. P2 requests drive 1 but is blocked.

a.P1 requests drive 2.

b.P2 requests drive 2 and gets it.

c.P2 requests drive 1 but is blocked.

d.P1 releases drive 1.

Soon the following sequence transpires:

P2 requests drive 2 and gets it.

Explanation:

A deadlock is a condition where two computer programs allocate the same resource essentially prevent access by each other and both programs stop working.

When every process or thread is awaiting for a resource to be released which is managed by another process a number of processes or themes are blocked.

Here is an example of a deadlock scenario. All connections are blocked; everybody hopes to see an incident that never takes place.

solution:

this situation is called an ip conflict.

data from a server is sent in small bits called packets. in an ip conflict, some packets will end up in one computer while some other packets will end up in another computer.

so…overall none of the computers get the data as the original message or picture being sent by the server cannot be retrieved with only half the packets. so it will show up as an error.

thus the final answer is d.
