Subnet

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.

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.

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.

A protocol that determines the optimal path for data packets to travel across interconnected networks.

Mutual Transport Layer Security — a protocol where both client and server authenticate each other using certificates.

Replacing dedicated network hardware with software running on commodity servers.

A server that sits in front of web servers and forwards client requests to the appropriate backend server.

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

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

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

The automated coordination and management of network resources, services, and policies across infrastructure.
