HTTPS

Computer Network

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

TCP/IP

Transmission Control Protocol/Internet Protocol — the fundamental communication protocol suite powering the internet.

HTTP

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

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.

Replacing dedicated network hardware with software running on commodity servers.

The practice of continuously observing a computer network for slow or failing components.

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

A network topology where each node relays data for the network, providing self-healing and redundant paths.

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

Virtual Private Network — a technology creating a secure, encrypted connection over a less secure network like the internet.

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

Dynamic Host Configuration Protocol — automatically assigns IP addresses and network configuration to devices.
