Answer:
A. VLOOKUP
Explanation:
VLOOKUP is an Excel function to look up data in a table organized vertically. VLOOKUP supports approximate and exact matching, and wildcards (* ?) for partial matches. Lookup values must appear in the first column of the table passed into VLOOKUP.
Purpose
Lookup a value in a table by matching on the first column
Return value
The matched value from a table.
Syntax
=VLOOKUP (value, table, col_index, [range_lookup])
Arguments
value - The value to look for in the first column of a table.
table - The table from which to retrieve a value.
col_index - The column in the table from which to retrieve a value.
range_lookup - [optional] TRUE = approximate match (default). FALSE = exact match.

Complete Question:
Recall that with the CSMA/CD protocol, the adapter waits K. 512 bit times after a collision, where K is drawn randomly. a. For first collision, if K=100, how long does the adapter wait until sensing the channel again for a 1 Mbps broadcast channel? For a 10 Mbps broadcast channel?
Answer:
a) 51.2 msec. b) 5.12 msec
Explanation:
If K=100, the time that the adapter must wait until sensing a channel after detecting a first collision, is given by the following expression:
The bit time, is just the inverse of the channel bandwidh, expressed in bits per second, so for the two instances posed by the question, we have:
a) BW = 1 Mbps = 10⁶ bps
⇒ Tw = 100*512*(1/10⁶) bps = 51.2*10⁻³ sec. = 51.2 msec
b) BW = 10 Mbps = 10⁷ bps
⇒ Tw = 100*512*(1/10⁷) bps = 5.12*10⁻³ sec. = 5.12 msec
