Answer:
a combined device for modulations and demodulations
Answer:
a) 4 processes
b) 2 resources
c) R1: 2 instances
R2: 2 instances
d) R2
e) R1
f) R1
g) No resource
h) R1
i) R2
j) R2
k) No
l)No deadlock
Explanation:
You need to know that the resources that are required by the processes for completion are shown by the request edge and the resources allocated are shown by the allocation edge. And thus, we can find what resources are allocated to the process, and required for the completion accordingly. And here again, the cycle is created, and hence deadlock may or may not occur. However, we see that resources have multiple instances and get freed on time. And hence, deadlock does not occur.
Like,
P4 uses R2 and free one instance of R2.
P3 then uses one instance of R2 and free R2.
P3 then uses one instance of R3 and free R3.
P1 uses one instance of R1 and free R1 one instance
P1 then uses R2 and free R2.
P2 uses R1 and free R1.
Hence, all the processes are complete and deadlock does not occur.
Answer:
Major risks include computer security and maintability of the software and hardware components of the computers in these objects.
I may feel more scared if I was riding a roller coaster that was computer controlled because if there were vunerabilities in the computer's software, a hacker could exploit that and remotely have access to the controls of the roller coaster, putting many people's lives at risk.
I think the benefits of computerizing an increasing number of everyday objects outweigh the potential risks.
This is because computers is very reliable and they do exactly what you tell them to do. However, humans are clumsy and can sometimes be extremely stubborn. Computerizing more everyday objects is an overall good thing for society, however, policies and protocols need to be followed to ensure these computerized objects remain secure.
