Answer:
There could be a collision if a hidden node problem occurs.
Explanation:
CSMA/CA(carrier sense multiple access/ collision avoidance) is a multiple access method in wireless networking, that allows multiple node to transmit. Collision avoidance of this method is based on preventing signal loss or downtime as a result of collision of transmitting multi signals.
If a node at step 4(transmit frame) sends the first frame, the node still needs to send a RTS(request to send) and to receive a Clear to send (CTS) from the WAP, the is to mitigate the issue of hidden node problem as all frame are treated as unit, so other listening nodes, not detected would seek to connect and transmit as well.

It is used to insert a specific function by selecting it from the Insert Function list.
Explanation:
The insert function list various functions, and we can insert a specific function through a selection of one of the options from the insert function list. And it is certainly not used to display the information according to arguments used in the function, and which is quite clear. Also, it is used to put each type of excel functions in a certain order.

Answer:
D
Explanation:
I don't know the language, but it is clear what is going on.
It looks like you are defining a value for a in both commands.
a.multiply(b); looks like you take the value in a (which is 10) multiply it by 25 and put the result back in a. So so far we have 10 * 25 = 250
Note the next command
a.add(b)
looks like you take the current value in a(which is now 250)
and put the value of b (which has not been changed. It is still 25) and put that in a (which is 250).
The result is 250 + 25 = 275
The answer is D. Since I only understand the logic, if this answer is wrong, I wish you'd leave a note.
