Which formula contains an absolute cell reference? =SUM($B$7:$B$9)
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:
The correct answer to the following question will be option c. Cat-6.
Explanation:
Cat-6: A standard version of twisted pair cable for physical layer of networking and for Ethernet is, Cat-6 (Category 6) cable.
- Cat-6 will be adaptable with the Category 5/5e and 3 standard of cables, and the standard specifies the performance of cable compared to 100 MHz up-to 250MHz for Cat 5/5e.
- So, if you are looking for the best cabling system to use while installing the Gigabit Ethernet, Category 6 will be the suitable one.
