Networking Fundamentals Flashcards

Flashcards based on lecture notes about networking concepts, topologies, the OSI model, SOHO networks, binary numbers, and troubleshooting methodologies.

A __ is a collection of computers and other devices connected by a transmission medium, providing an opportunity for shared resources.

IT Network

In a __ network, only two nodes are connected to the network media.

point-to-point

In a __ each node is connected to a concentrator over dedicated network media.

star topology
