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.
What is referred to the description above is the term SELECTIVE ATTENTION. When there is selective attention, there are certain memories that are only selected and these are processed to become part of the short-term memory. Not everything that is being sensed is remembered.
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.
Answer:
def leap_year_check(year):
return if int(year) % 4 == 0 and (int(year) % 100 != 0 or int(year) % 400 == 0)
Explanation:
The function is named leap_year_check and takes in an argument which is the year which we wish to determine if it's a new year or not.
int ensures the argument is read as an integer and not a float.
The % obtains the value of the remainder after a division exercise. A remainder of 0 means number is divisible by the quotient and a remainder other wise means it is not divisible by the quotient.
If the conditions is met, that is, (the first condition is true and either the second or Third condition is true)
the function leap_year_check returns a boolean ; true and false if otherwise.
