Answer:
C. Mean
Explanation:
Mean = (∑
)/N
Median = central values when data is sorted
Mode = most repeated value
Standard deviation = 
In standard deviation, formula you may see that deviation is being calculated from the mean (central location). But here we take square of the value before adding all of them.
But if we just take 
, it would be equal to zero.
<u>EXAMPLE</u>
Take 4, 9, 5 as data
mean = (4+9+5)/3 = 18/3 = 6
sum of deviations from mean = (4-6)+(9-6)+(5-6) = (-2)+(3)+(-1) = 0

C Pull technology
Explanation:
Pull technology is a form of network mode of communication in which the initial data request comes from the client side of the network for it to be handled by the server side of the network.
Given that Nicola wants a demand-based content to his website for customers to access information when they wish to, the process is similar t the podcasting in which each new content is posted to a specific RSS feed from where it can be requested by a mobile app, directory or a RSS feed reader
The counter technology is a push technology where the servers push content to intended clients, such as for an incoming call, instant messaging, synchronous conferencing (online c h a t) and files.
