Networking and Architecture

This Networking and Architecture classroom training courses is included in some NowSkills Apprenticeship Standards. Please check our schedule for the location and date of your training. The classroom courses learners attend will vary depending upon the Apprenticeship Standard they are completing.

Duration

5 working days (Monday-Friday)

Who should attend?

The Networking and Architecture course is suitable for any apprentice leaving secondary or tertiary education who has a keen interest in Digital IT and who is enrolled onto a NowSkills Apprenticeship.

What will the apprentice learn?

The Networking and Architecture course will develop the apprentice’s knowledge, skills and understanding of the following:

Understanding network infrastructures

  • Understand the concepts of Internet, intranet, and extranet

    • Perimeter networks; addressing; reserved address ranges for local use (including local loopback IP), VLANs; wired LAN and wireless LAN
  • Understand wide area networks (WANs)
    • Leased lines, dial-up, ISDN, VPN, T1, T3, E1, E3, DSL, cable, and more, and their characteristics (speed, availability)
  • Understand wireless networking
    • Types of wireless networking standards and their characteristics (802.11a,b,g,n, including different GHz ranges), types of network security (WPA, WEP, 802.1X, and others), point-to-point (P2P) wireless, wireless bridging
  • Understand network topologies and access methods
    • Star, mesh, ring
