Unit 5 Flashcards
This layer is also where you identify the interface between the data terminal equipment (DTE) and the data communication equipment (DCE).
Physical Layer
is usually located at the service provider
DCE
is the attached device
DTE
DTE stands for
Data Terminal Equipment
Two main types of Transmission Media
Guided Media
Unguided Media
Requires Physical Medium
Guided Media Transmission Media
Requires air for communication
Unguided Media Transmission Media
Functions as a multi-port repeater, reamplifying and forwarding incoming digital signals to all connected ports without examining the data.
as a result all devices within share the same collision and broadcast domains.
Hub
is the type of topology a hub creates where the hub is a central device and cables extend in all directions out from it
physical star network
What kind of topology do Ethernet networks run
bus topology
type of network topology where the signal has to run through the network from end to end.
bus topology
Different types of Topology
Bus Topology
Ring Topology
Star Topology
Mesh Topology
Hybrid Topology
Types of Topology
every workstation is connected to a single cable, meaning every host is directly connected to every other workstation in the network.
bus topology
Types of Topology
computers and other network devices are cabled together in a way that the last device is connected to the first to form a circle or ring
ring topology
Types of Topology
Common Ethernet physical layout where a central switch connects devices. Physical connection is commonly made using twisted-pair wiring.
Star Topology
