network reference models Flashcards
a schematic description of a network arrangement, connecting various nodes through lines of connection.
network topologies
a network topology type where computers are connected to a single hub through a cable.
star topology
a network type in which every computer and network device is connected to a single cable
bus topology
when a bus topology has exactly two endpoints, then it is a ____
linear bus topology
a network type that forms a ring as each computer is connected to another computer, with the last one connected to the first– exactly two neighbors for each device
ring topology
a network type that has a root node and all other nodes are connected to it forming a hierarchy.
also called “hierarchical topology”
should at least have 3 levels tot he hierarchy
tree topology
a point-to-point connection to other nodes or devices.
mesh topology
types of mesh topology:
- partial mesh topology
- full mesh topology
a type of mesh topology where some systems are connected in the same fashion as mesh topology, but some devices are only connected to two or three devices
partial mesh topology
a type of mesh topology where each node or device is connected
full mesh topology
a network type that consists of a mix of two different types of topologies merging as one network
hybrid topology
common network devices:
- terminal device
- switch
- router
- firewall
- wireless devices
it is the end-device of the data communication system.
it provides the necessary functions required by the user access protocol operations
- data terminal equipment (DTE) such as the PC, phone, handsets, printers, and servers.
- network interface card is a key component that connects directly to a device that allows access to a network such as an internet or a local network
terminal device
