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:
Explanation: Input : arr[] = {1, 2, 3, 4, 5}
Output : 3
Sum of the elements is 1+2+3+4+5 = 15
and total number of elements is 5.
So average is 15/5 = 3
Input : arr[] = {5, 3, 6, 7, 5, 3}
Output : 4.83333
Sum of the elements is 5+3+6+7+5+3 = 29
and total number of elements is 6.
So average is 29/6 = 4.83333.
CASE tools are used to boost analyst output, enhance user-analyst collaboration, and incorporate life cycle tasks.
Chip and Anna would communicate with one another and discuss parts of the design that they have finished using CASE tools.
Due to the enormous number of users in a system, CASE tools will help to simplify communication among all users and analysts, therefore this would be helpful to Chip and Anna as well.
They could also employ CASE tools to help them record the data they have obtained from questionnaires, interviews, and document analysis.

<span>b)
</span>Symmetric Cryptography
<span>
<span>c)
</span>Algorithm
<span>
<span>d)
</span>Digital signature
The answer is
(D) Digital Signature
It uses the private key of a sender and is a mathematical
technique that validates the integrity and authenticity through a public key
encryption of a digital or a software document. It is normally attached to digital
or a software document to verify the sender’s identity and its content.

Answer:
Modern CPUs contain multiple cores. Think of it as multiple smaller CPU's on the single CPU chip. The multiple cores can handle different processes in parallel allowing for multiple programs to be running at the same time. This is not considered true multi-processing since the architecture still has a single I/O bus and can be subject to a single point of failure. But the operating system will take advantage of the additional cores as if they were multiple physical CPU's - enhancing performance and productivity.
