Explain why data transmission over long distances is usually done via a serial scheme rather than parallel.
Analysis:
The reason why serial transmission of data is preferred over parallel transmission over long distances is that serial transmission requires only one data path whereas parallel transmission requires one path for each bit that makes up a word. That may imply 8, 16 or more paths depending on word length. This not only adds cost but also system complexity. The advantage is increased speed or data rate with parallel transmission.

(a) Johnston and Gilman also observed that at a constant temperature the dislocation velocity obeyed a power law. See Eq. 5.20. Assuming that the dislocation velocity exponent, m, is 16.5 and that the stress, D, for a velocity of 1 cmx s-1 is 5.30 MPa, determine the stress needed to obtain a velocity that is 5 times greater than that given in Eq. 5.21.
