Packet Sniffing

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.

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.

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

Border Gateway Protocol — the routing protocol that manages how packets are routed across the internet between autonomous systems.

Replacing dedicated network hardware with software running on commodity servers.

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

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

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

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

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

Monitoring

The continuous observation of system performance, availability, and health using automated tools and dashboards.
