Computer Networks

 

Aim and purpose

The aim of this unit is to ensure learners understand the key components of networked systems, know about network protocols and the services provided by network systems and develop the skills required to ensure network security.

Unit introduction

Networks are used in one way or another by virtually every organisation, from simple use of internet services through internal file sharing to wide area networks exchanging data across continents. Therefore, it is essential that learners thinking of careers within the IT industry have a good understanding of the underlying principles of networking and how data travels around networks.

 

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 develop an understanding of their functions and how they relate to each other, particularly how connections are made and the purpose of these connection devices.

 

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. Learners will explore and use the different services available.

 

For networks to be suitable they must be secure and networks distributed across several physical locations, perhaps via a WAN, makes the ensuring of security a complex business. Learners will be exploring the technologies used to create secure systems and putting security procedures and devices in place to secure a networked system. Learners will come to understand the risks to businesses from insecure networks.

Learning outcomes

On completion of this unit a learner should:
1 Know types of network systems and protocols
2 Understand the key components used in networking
3 Know the services provided by network systems
4 Be able to make networked systems secure.
