This course is designed to give a practical knowledge of the type of electronic circuitry used in a modern Computer System or in any type of Computer Controlled equipment such as Photocopiers, Cash Registers, and many other types of IT equipment. Digital Electronics involves the use of Silicon chips (Integrated Circuits). The internal structure of a computer is to a large extent comprised of Digital Electronic Circuits.
Duration and Schedule
This course equips participants with practical “Hands-on” skills relevant to the workplace and the theory required for certification. Participants can expect to have the skills
