Trailer: It contains the error detection and error correction bits. It is also called a Frame Check Sequence (FCS).

Explanation:

In the context of data-link frames, the trailer is the final part of the frame structure. It typically contains two important components:

Frame Check Sequence (FCS): The FCS is a field in the trailer that is used for error detection. It is a checksum or a cyclic redundancy check (CRC) value calculated based on the contents of the entire frame, including the header, data, and sometimes the trailer itself.

End Delimiter: The end delimiter is a specific bit pattern or sequence of bits that marks the end of the frame. It helps the receiving device recognize the end of the frame and differentiate it from subsequent frames.

Thus, the trailer, along with the header and data, forms a complete data-link frame. It is used for reliable transmission of data across a network by incorporating error detection mechanisms and frame boundaries.

The new job time after improving input by 50%, computation by 10%, and output by 20% is 63 seconds, a 21.25% improvement from the original 80 seconds.

Let's call the time to read in data T1, the time to complete the computational task T2, and the time to print the results T3. Then, the original job time was T1 + T2 + T3 = 10 + 20 + 50 = 80 seconds.

After improving the input by 50%, T1 becomes 10 / 2 = 5 seconds.

After improving the computation task by 10%, T2 becomes 20 * (1 - 0.10) = 18 seconds.

After improving the output by 20%, T3 becomes 50 * (1 - 0.20) = 40 seconds.

The new job time is T1 + T2 + T3 = 5 + 18 + 40 = 63 seconds. So the new job time is reduced to 63 seconds, which is a 21.25% improvement from the original job time of 80 seconds.

It's important to note that the improvement percentages are relative, so improving an operation by a certain percentage will result in a smaller absolute improvement as the time for that operation decreases. In this example, although the improvements in input and output times were both by 50% and 20% respectively, the absolute improvement in time for each operation was smaller as the time for each operation was reduced. This highlights the importance of continuously re-evaluating and optimizing all parts of a process to achieve the greatest overall improvement.
