a condition where signals from different machines are blocked from each other by objects or distance even though they can all communicate with the central access point

the "point" at which one network is linked to an internet; serves as a passageway between the network and the outside world

a type of network that typically links machines over a great distance - perhaps in neighboring cities or on opposite sides of the world

an autonomous program that transfers itself through a network, taking up residence in computers and forwarding copies of itself to other computers

a name registered with ICANN for identification purposes

acts as an intermediary between a client and a server with the goal of shielding the client from adverse actions of the server

a way of safeguarding sensitive information when sent over a network

the organizations responsible for constructing and maintaining the networks that make up the Internet

a notational system for representing bit patterns

a protocol that is considered connectionless and unreliable, but is still used for DNS lookups and VoIP

a central (short) bus to which computers are connected to form a bus network

connects several bus networks to form a larger network

provides a link between networks to form an internet in which the original networks maintain their unique internal characteristics

a device that simply passes signals back and forth between two buses - usually with some form of amplification - without considering the meaning of the signals

a device that connects two buses but only passes messages across the connection if that message is destined for a computer on the other side

handles actual transmission of segments/packets from one machine to another

converts messages into segments/packets that are compatible with the Internet and reassembles messages that are received

prepares messages and provides destination address; receives messages

assigns intermediate address to each segment/packet; detects that segment/packet has reached final destination (in other words, this deals with directing the segments/packets through the Internet)
