Learners will learn about different network types and the standards that relate to them. The will also develop an understanding of the key components, protocols and applications that support networking in order to configure a network to meet organisational requirements.

Unit Learning Outcomes


Understand network components, protocols and applications.

Types of networks, how they are used and configured, to include: client server, peer to peer, internet, mobile.

Interconnection devices (hardware): routers (wired and wireless), switches, hubs (wired and wireless), firewalls, cable types and connectors (Cat 5-6, coaxial, fibre), wireless access points, network interface cards (wired and wireless).

Topologies, logical and physical (star, bus, ring, mesh).

Protocols and standards: TCP/IP, DNS, DHCP, HTTP, FTP SMTP, 802.x, Bluetooth, 3G, 4G, 5G.

Factors that affect range and interference: noise, distance, cabling issues.

Applications: web services, databases, antivirus.

Software: operating systems (Windows, Linux, Mac OS Server).

Assessment Criteria

  • 1.1

    Explain the components and applications used in networking.

  • 1.2

    Explain the role of network topologies, standards and protocols in networking.

  • 1.3

    Explain how network applications and software support networking.


Be able to configure a secure network.

Configure a network (a peer-to-peer or client-server network depending on hardware and software)

  • Selecting and configuring network components, to include: server(s), nodes (mobile devices, workstations), interconnection devices (switches, hubs, routers).
  • Selecting and configuring differing types (wireless or wired)
  • Installing network operating systems.
  • Configuring services (DNS, Active Directory (AD)).

Modify a network

Making it more secure, as well as configuring it for specific organisational requirements. Example modifications could include: configuring Internet Protocol (IP) addresses, managing domains, adding user types and groups, installing and configuring antivirus software and firewalls.

Apply and configure network security

Securing the network by undertaking the following tasks: setting up, changing, managing passwords and policies, administering authorisation, setting up user accounts with different permissions, restricting new services according to permissions, access controls, backing up and restoring, intrusion detection systems.

Encryption: physical security (CCTV, access, biometrics, locks, firewalls, antivirus).

Assessment Criteria

  • 2.1

    Configure a network to meet organisational requirements.

  • 2.2

    Modify the network in response to feedback.

  • 2.3

    Apply and configure network security.


Be able to troubleshoot and review a network.

Troubleshoot a network

Testing a given network using available networking tools (ping, benchmarking, IPCONFIG).

Documenting network testing against benchmarks in a professional manner for a range of user groups, including end users and management.

Troubleshoot and repair routine issues: faulty cables, interface card and other hardware, IP address conflict.

Review the finished network in relation to: organisational requirements and user experience (e.g. usability and reliability), security, fitness for purpose, any constraints (resources, time etc), strengths and improvements.

Identify potential improvements by evaluating the following aspects of a network: performance, capacity, accessibility, portability, reliability, scalability, manageability.

Assessment Criteria

  • 3.1

    Troubleshoot a network and respond appropriately to any errors or problems.

  • 3.2

    Review how the network meets requirements, making suggestions for further improvements.
