Answer: A central wireless access point (AP)
Explanation:
A central wireless access point (WAP) is a hardware device which can be configured on a local area network connecting WLAN to the wired network.
These APs have built in routers which enables wireless devices to connect with it. Mostly they are hardwired to devices such as in network switches or modems.
These access points are found in many institutions, organisations, enterprises which enables devices to be connected to them and provides access to the internet and resources.
There are also public access points which enables people travelling by public transport to connect through them and in many business organisation there are closed APs for use only by the employees of them which enables file sharing and information processing.
Answer:
A. Big Data
Explanation:
It is big data. The internet searches, customer transactions, social media posts, medical tests, weather sensors, military surveillance, and all the data source you are seeing around yourself forms together with the big data. And a big social media company gathers around so many petabytes of data each day. And there are so many such companies, plus all sorts like eLearning sites, etc. And all these together form the big data.

Answer:
t= 8.7*10⁻⁴ sec.
Explanation:
If the signal were able to traverse this distance at an infinite speed, the propagation delay would be zero.
As this is not possible, (the maximum speed of interactions in the universe is equal to the speed of light), there will be a finite propagation delay.
Assuming that the signal propagates at a constant speed, which is equal to 2.3*10⁸ m/s (due to the characteristics of the cable, it is not the same as if it were propagating in vaccum, at 3.0*10⁸ m/s), the time taken to the signal to traverse the 200 km, which is equal to the propagation delay, can be found applying the average velocity definition:

If we choose x₀ = 0 and t₀ =0, and replace v= 2.3*10⁸ m/s, and xf=2*10⁵ m, we can solve for t:

⇒ t = 8.7*10⁻⁴ sec.
