check digit.....an extra digit at the end of code whichncan be used for checking accuracy and control purposes.
there are two ways of check digit
by the sum of the code.
and the most popular check digit system ....modules11 check digit system. eg isbn( international standard book number) on the book.
tht all i know......


pseudocode.....it is another programming analysis tool,which is used for planning program logic.these pseudocode used english phrases and are not understood by the computer.
advantage.....it is problem oriented ie the programmer think in related to her problem rather than in term of machine.
pseudocode doesnt have any syntax rules for formulating instruction.

i hop tht helps :)

Pilot implementation is running the system, to check that it meets all the requirments, and then implementing it to the business
NOTE: stick to parralel running and direct changeover ( since they are the easiest)

Procedures could be used by many different programmers without the need of it to be rewritten

the new computerised system has been installed.describe the ways in which the training of staff to use the new system might be done?
by using CAL ( computer aided learning) or by the use of CBL ( computer based Learning)
