TCP/IP

Computer Network

A collection of interconnected computing devices that share resources and communicate using standardised protocols.

HTTP

Hypertext Transfer Protocol — the application-layer protocol for transmitting hypermedia documents on the World Wide Web.

HTTPS

HTTP Secure — an encrypted version of HTTP using TLS for secure communication over the internet.

DNS

Domain Name System — the hierarchical system that translates human-readable domain names into numerical IP addresses.

IP Address

A unique numerical label assigned to each device connected to a computer network for identification and routing.

IPv6

The most recent version of the Internet Protocol, providing a vastly larger address space than IPv4.

Subnet

A logical subdivision of an IP network that improves security and performance by segmenting traffic.

Software-Defined Networking

An approach to networking that uses software-based controllers to manage network behaviour centrally.

Wi-Fi 6

The sixth generation of Wi-Fi technology offering improved speed, capacity, and performance in dense environments.

Network Latency

The time delay between sending and receiving data across a network, measured in milliseconds.

Bandwidth

The maximum rate of data transfer across a network path, typically measured in bits per second.

Throughput

The actual rate of successful data transfer across a network in a given time period.

The fifth generation of mobile network technology offering higher speeds, lower latency, and massive device connectivity.

Software-Defined Wide Area Network — a virtualised network architecture that enables centralised management of geographically distributed networks.

The arrangement of elements such as nodes, links, and devices in a computer network.

Network management techniques that prioritise certain types of traffic to ensure consistent performance.

Secure Sockets Layer/Transport Layer Security — cryptographic protocols providing secure communication over a computer network.

Network Address Translation — a method of mapping one IP address space into another by modifying packet headers.

Virtual Local Area Network — a logical grouping of network devices that communicate as if on the same physical network.

Dividing a computer network into smaller subnetworks to improve security and performance.
