Unit 9: Principles of Networking

This unit starts by exploring the different types of networks and the standards
relating to network systems, including local and wide area networks. Networks can
be either wired or wireless systems and, although much of the underpinning content
is similar, this unit does make reference to both.
The hardware and software components used in networks and their operation are
explored and learners will build an understanding of their functions and services and
how they relate to each other. As users of networks, we work with them mostly
through the services that they provide, from simple services such as file sharing and
communications to more complex services involving security and account
management.
For networks to be practical, they must be secure and the nature of them being
distributed across several physical locations, perhaps via a WAN, makes the ensuring
of security a complex business. Learners will understand key network security issues
as well as exploring the technologies used to create secure systems.

Learning outcomes

On completion of this unit a learner should:
1. Know the types of network systems and related standards
2. Understand the hardware and software used in networking
3. Know the services provided by network systems
4. Understand how networked systems are made secure
