Digital Subscriber Line Access Multiplexer
A network element which multiplexes the traffic coming from the

domain name service
Domain name service (DNS) is used for translating names of network
nodes into addresses.
dynamic routing
Dynamic routing maintains information of routes that may change
over time. Dynamic routes are created and configured when routers
broadcast Routing information protocol packets advertising the
networks they can reach and the distance (number of routers) to each
network.
encapsulation
Wrapping of data in a protocol header.
Ethernet
LAN specification IEEE 802.3.
firewall
A system or a group of systems that enforce access control between

default gateway
A default gateway is the router to which M10 will send a packet if it
does not know how to reach the packet’s destination host.
half-duplex
Communication between terminals one direction at a time.
