Answer:
backup; recovery
Explanation:
Backup and recovery refers to the process of backing up data in case of a loss and setting up systems that allow that data recovery due to data loss. Backing up data requires copying and archiving computer data, so that it is accessible in case of data deletion or corruption. Data from an earlier time may only be recovered if it has been backed up.
Data backup is a form of disaster recovery and should be part of any disaster recovery plan.In some cases, backing up or restoring entire systems, or the enterprise, after an event or disaster can take days

<span>A function is a pre-written formula that is built into excel.
There are many functions which are pre-written into excel.
Some examples are the SUM function which adds the values in a given range. The AVERAGE function takes the average of values in a given range, etc.

When the increment or decrement operator is placed before the operand (or to the operand's left), the operator is being used in prefix mode. Postfix mode on the other hand is when the increment or decrement operator is placed after the operand (or to the oper and's right) .
Answer:
The answer is below
Explanation:
Given that:
Frame transmission time (X) = 40 ms
Requests = 50 requests/sec, Therefore the arrival rate for frame (G) = 50 request * 40 ms = 2 request
a) Probability that there is success on the first attempt = 
but k = 0, therefore Probability that there is success on the first attempt = 
b) probability of exactly k collisions and then a success = P(collisions in k attempts) × P(success in k+1 attempt)
P(collisions in k attempts) = [1-Probability that there is success on the first attempt]^k = ![[1-e^{-G}]^k=[1-0.135]^k=0.865^k](https://tex.z-dn.net/?f=%5B1-e%5E%7B-G%7D%5D%5Ek%3D%5B1-0.135%5D%5Ek%3D0.865%5Ek)
P(success in k+1 attempt) =
Probability of exactly k collisions and then a success = 
c) Expected number of transmission attempts needed = probability of success in k transmission =
