Answer:
A union (UNION(x,y)) of the sets Sx and Sy represented by x and y, respectively will perform ________4_________ update(s) of the attribute.
Explanation:
The UNION (x, y) disjoint-set data structure unites the dynamic sets that contain x and y, say Sx and Sy, into a new set. It is called the union of the two sets. Before the union operation, the two sets are disjoint. After the union operation, the representative of the resulting set is some member of Sx and Sy or either Sx or Sy. The sets Sx and Sy are then destroyed to remove them from the union collection S. So, four operations are required.
Answer:
Proper Authentication is required. Not all the people should get all the data. If this is the case then you are definitely going to find that data protection is breached. We need to define each user's role as well as privileges clearly or else we are definitely going to suffer. Always ensure proper authentication.
Explanation:
We need to define each user's roles and privileges. And that can be done through Authentication and Authorization,
Answer: B) The volume of the radio and D) the outdoor temperature.
Explanation:
The analog signal is the signal that continuously varying with the time and it continuous analog signal. Analog signal is basically used to carry information or data from one device to another device.
The volume of the radio is the example of the analog signal as it carry voice from one place to another. The analog signal is the type of signal that use to measure the particular change in the physical phenomena like pressure, sound and temperature in the environment. So, outdoor temperature is also the example of analog signal.
And the other options (A) and (C) are incorrect because it is represent any physical change in the environment.
