Protocols

Lösung anzeigen
TESTE DEIN WISSEN

Protocols govern the communication between devices

A protocol is a set of rules that guide communication.

Communication between devices on a network is organised by protocols.

In computing, protocols ensure that data transfer can happen regardless of the transmission media or the connected devices.

It can be thought of as ensuring that all networked devices (at the core or on the edge) speak the same language and consistent responses are given to specific requests. 

Where specialist devices or local networks use non-standard protocols (in other words, their own language), they need to provide a means of translation when interfacing with the internet.

What is the network core?

Lösung anzeigen
TESTE DEIN WISSEN

The network core refers to the components that provide services to those at the edge. This includes facilities that are often within data centres like servers and those within the data link layer.
