Document Summary

A computer network is a group of computers that connect through hardware and software to communicate. Every device connected to a network is a node can be a personal computer, a peripheral device (e. g. printer, router, switch) Allow devices to share info and services with each other like files, connected devices (e. g. printers) and connection to internet. Throughput is speed at which data is currently moving through the network. Bandwidth is the maximum speed that data could possibly be moving through the system: both are typically measured in megabits/second (mbps where one megabit is 1 million bits) All networks are defined by their network architecture, which is determined by 4 factors: distance between nodes, network administration, the protocol (rules on how information is exchanged, the medium (what is used to transport information) Each factor can be used independently to broadly describe a computer network and all. 4 combined can give a near complete definition of a particular network.
