Answer:The answer is (c).first.
Explanation:
In doubly linked list each node possesses the address of next node(except last node) because there is no node present after the last node .
and the address of previous node(except first node) because there is no node present before the first node.
So the conclusion is that the first node does not contain the address of previous node and the last node does not contain the address of the next node.
KE is the energy possessed by an object by virtue of it being in motion. PE is the energy possessed by an object by virtue of its position. It can be transferred from one object to another and this happens during collisions. Potential Energy, on the other hand, cannot be transferred from one object to another.
Over a TCP connection, suppose host A sends two segments to host B, host B sends an acknowledgement for each segment, the first acknowledgement is lost, but the second acknowledgement arrives before the timer for the first segment expires is True.
True
<u>Explanation:</u>
In network packet loss is considered as connectivity loss. In this scenario host A send two segment to host B and acknowledgement from host B Is awaiting at host A.
Since first acknowledgement is lost it is marked as packet lost. Since in network packet waiting for acknowledgement is keep continues process and waiting or trying to accept acknowledgement for certain period of time, once period limits cross then it is declared as packet loss.
Meanwhile second comes acknowledged is success. For end user assumes second segments comes first before first segment. But any how first segment expires.
The effort is necessary in making sure that the data is meaningful, correct, and timely. Many analysts are increasingly focused on quality on a per-attribute basis instead of a per-report basis. This will avoid excess control of access and instead focus on meaning. A data-driven organization that includes a comprehensive data cleanup is able to make informed choices that maximize value on strategic investments.
