Answer:
- The simplified expression is:

- The simplified expression is undefined for m=3
Explanation:
The given expression is:

The numerator can be siplified by using factorization and denominator will be simplified using the formula

So,

A fraction is undefined when the denominator is zero. In order to find the value of m on which the simplified fraction will be undefined we will put denominator equal to zero.
So,

Hence,
- The simplified expression is:

- The simplified expression is undefined for m=3
It allows for more accurate sizing of networks.
Answer:
that's muddled up I can't make out the question
Answer: If two different station are addressed with the same hardware address then there are chances of occurrence of the failure in the network at irregular intervals.The failure or error will occur because of the both the devices are seen as one by the network due to same address.
An intelligent network system id used ,it can identify the error can help in the prevention of the failure.Other option for configuring the situation is assigning the MAC(media access control)address to devices which are unique in nature thus, no device can have same address.
Answer: Direct competitive
