(b) Explain two circumstances under which the use of wireless communication would be preferred in data communication.
(c) Figure 2 is an extract of a spreadsheet showing what the students had targeted to score and the actual score in a computer remedial class.

A performance factor is obtained by subtracting the target score from the actual score and dividing the difference by the target score.
Write a formula that uses cell references only that would be entered in cell:
(i) D2 to compute the performance factor.
(ii) E2 to display the statement ‘more remedials’ if the performance factor is less than zero, ‘exempted’ if the factor is greater than zero and ‘optional remedials’ if otherwise.
(iii) D8 to display the best performance factor.

RESPONSES

(a) Ways ¡n which internet makes reporting of corruption easier.

Interactiveness: the internet based technology enables real-time dialogue hence instantaneous reporting of cases;
Outreach: the technology allows the coverage of wide areas/can be reported from anywhere;
Social mobilisation: It is easy to use technology to create a network with people or organisations with similar concerns;
Anonymity: With use of the technology, it has become easy to report corruption cases without being known;
Security: The message sent reaches the destination with less risk of being intruded.

(b) Circumstances when wireless is preferred

When the targetted recipients are many and diverse e.g. different platforms, devices, geographical locations.
When the sender or receiver is mobile and it in practical to use wired media.
When there is no space or it is inconvenient to lay cables e.g in a congested town.
When the distance of travel is very big e.g extraterestial communication.

A performance factor is obtained by subtracting the target score from the actual score and dividing the difference by the target score. Write a formula that uses cell references only that would be entered in cell: (i) D2 to compute the performance factor. (ii) E2 to display the statement ‘more remedials’ if the performance factor is less than zero, ‘exempted’ if the factor is greater than zero and ‘optional remedials’ if otherwise. (iii) D8 to display the best performance factor.
