Please answer the following Operating Systems Quetion and its two parts: Part A: A distributed system using mailboxes has two IPC primitives, send and receive. The latter primitive specifies a process to receive from and blocks if no message from that process is available, even though messages may be waiting from other processes. There are no shared resources, but processes need to communicate frequently about other matters. Is deadlock possible? Discuss. Part B: One way to prevent deadlocks is to eliminate the hold-and-wait condition. In the textbook it was proposed that before asking for a new resource, a process must first release whatever resources it already holds (assuming that is possible). However, doing so introduces the danger that it may get the new resource but lose some of the existing ones to competing processes. Propose an improvement to this scheme. * Please answer both parts correctly, and I will provide a Thumbs Up. Thanks.

Question

Hello. Please answer the attached Operating Systems question and its two parts correctly and completely.

*If you answer the questions correctly and completely, I will give you a thumbs up. Thanks.

Please answer the following Operating Systems Quetion and its two parts:
Part A:
A distributed system using mailboxes has
two IPC primitives, send and receive. The
latter primitive specifies a process to receive
from and blocks if no message from that
process is available, even though messages
may be waiting from other processes. There
are no shared resources, but processes need
to communicate frequently about other
matters. Is deadlock possible? Discuss.
Part B:
One way to prevent deadlocks is to eliminate
the hold-and-wait condition. In the textbook it
was proposed that before asking for a new
resource, a process must first release whatever
resources it already holds (assuming that is
possible). However, doing so introduces the
danger that it may get the new resource but
lose some of the existing ones to competing
processes. Propose an improvement to this
scheme.
