Network Organization
Networks[1]
There are different types of networks, often defined by the size of the network, which use different network devices.
- Students must be able to outline the features of PAN, LAN, WLAN, VLAN, VPN, SAN, WAN, and P2P networks.
Protocols are a system of rules that standardise how senders and receivers communicate over a network.
- Students must be able to explain the role of common protocols (TCP and IP) to ensure network hardware and software interoperability, how they are implemented (by hardware, software or a combination of both), and outline their role in the management of data integrity, flow control, deadlock, congestion and error checking.
Digital networks encapsulate and de-encapsulate communication into packets to route packets from a source to a destination.
- Students must be able to explain how Packet switching works and why digital networks encapsulate and de- encapsulate packets routed through ethernet, wireless, and Bluetooth communication standards.
