Overview
The Introduction to Data Communications training course is an instructor led presentation course that provides a fundamental overview of the hardware, protocols and techniques used in the modern datacommunications environment.
This technical training course will familiarise delegates with the way that data is transported, how data networks operate and the protocols, so that delegates will gain awareness of datacomms concepts and the vocabulary in use.
The course is generic in nature and is aimed at both technical and non-technical professionals new to the data environment. The technical skills and knowledge gained through the theory and practical training sessions can be used as a starter course before moving on to other more advanced data communications training courses.
Prerequisites
This is a foundation level course, ideal for anybody with an interest in Data Communications, as such no special prerequisites are necessary other than the desire to learn!
Delegates will learn how to
- The various techniques used in data communications
- The standards and protocols in use in Data networks
- The fundamental concepts of telephone networks
- Analogue to digital to analogue conversion
- Internet connectivity
- Mobile Data networks
- Convergence
