Explanation:
For example, when using the public phone box, wired transmission is done not wireless as in cell phones. Public phone box use electronic signals transmitted through a cable network to send voice data which are not very effective for long distance communication.
However, cell phones wirelessly send electromagnetic wave signal to a cell tower close to the caller and then the information is then transmitted to cell tower close to the receiver within a split of a second. This method of communication has much advantages.

Computer typesetting: Computerized typesetting, method of typesetting in which characters are generated by computer and transferred to light-sensitive paper or film by means of either pulses from a laser beam or moving rays of light from a stroboscopic source or a cathode-ray tube (CRT).
They are several weaknesses or disadvantages of file processing
systems but the major weakness is data redundancy and inconsistency. By data
redundancy, I mean duplication of data. There are no better methods to validate
insertion of duplicate data in file systems. Data redundancy can also increase
the chance for errors.
