taught hours while the remainder is for independent study and laboratory practical work. The unit
may be carried out on a full time or part time basis.
Assessment
This unit will be assessed by means of one three hour written examination paper.
Learners are expected to have elementary knowledge of probability for engineers, basic knowledge
of computer organisation, C language programming and computer operating systems as per City &
Guilds award 7267-503 or relevant HND or other equivalent.
