peripherals
devices that are only connected to a network through a host
hosts
devices that send and receive user devices
network media
connections between hosts and network devices
clients

protocols
definitions of how a message is transmitted and delivered
destination host
the computer that receives a message
frame
the specific format of a computer message
collision
the event of two frames impact

baseband
a transmission medium that can only transmit on one communication channel at a time
MAC address
a physical address that is required for every device that connects to a LAN
Media Access Control
MAC
Access Layer
level that provides connections in a local network
Distribution Layer
level that connects smaller networks
Core Layer
level that provides a high-speed connection for the Distribution Layer
IP Address
a logical address that is assigned based on the host’s location
routing
the process of finding the path to a destination host
collision domain
the area where a host can receive a garbled message
MAC Table
table that maps MAC addresses to ports
broadcast MAC address
FFFF:FFFF:FFFF:FFFF
broadcast domain
the group of devices that receive a broadcast frame
address resolution protocol
ARP
packet
part of a frame that contains source, destination, and the message
default gateway
the address used to send messages outside of the local network
ARP Table
the table that a host uses to store the MAC addresses of other host on the local network
routing table
a table that contains the addresses of networks
ping
a tool that verifies whether two hosts are connected
multi-function device
a device that acts as multiple network devices
baseline
the normal status of a network
access point
