Course description

Computer networks:

This online course describes the operation of fixed line and wireless computer networks that employ the Ethernet suite of protocols. The course describes network address schemes, protocols, functional elements and security methods.
This PTT online course is aimed at those responsible for the design, installation and maintenance of Ethernet local area networks.

This course builds on the introductory course “Ethernet fundamentals” to describe in detail the operation and security aspects of both fixed line and wireless local area networks.
The course begins by describing the problems associated with network loops and explains the operation of protocols that allow Ethernet switches to avoid such loops. The relative benefits of routing and switching and the roles of translating bridges, routers and switches are compared. The role and operation of ARP, NAT and DHCP protocols in address translation and allocation are discussed. Security in a LAN is discussed with reference to firewalls, proxy servers and a DMZ. The operation and topology of wireless networks is discussed with reference to the role of access points and a wireless controller. Finally, the security aspects of a WiFi system are discussed.

This course includes online assessments. A certificate of completion is awarded to successful participants.

Additional entry requirements
