![]() is implemented by different communication protocols.routers, device drivers, network interface controllers, ports, web servers, browsers, etc.) exchanges data between different hardware and software platforms belonging to that stage (e.g.is associated with a distinct stage of network communication.Network packets have a layered structure where each layer: different packets can use different routes for delivery) every packet chooses the best route available for transmission (i.e.there's no established connection between the server and the client. ![]() Thus, the internet is inherently a connectionless network, which means that: ![]() Information sent over the web is split into small data units (packets) where each packet includes all the information necessary for identification and routing, such as source and destination addresses and protocol identifiers. Packets are important because the internet is a packet-switched network - as opposed to circuit-switched networks such as voice telephone networks (see a comparison table of packet vs circuit switching by GeeksforGeeks). Network packet analysis can help you understand the performance and security implications of a network or application. ![]()
