How do nodes communicate with each other?
Routing messages between networks When a node on one network needs to send a message to a node on another network, this packet will be picked up by the router and passed on to the other network.
What are connections between nodes called?
We refer to the connections between the nodes as edges, and usually draw them as lines between points. In mathematics, networks are often referred to as graphs, and the area of mathematics concerning the study of graphs is called graph theory.
How does signal get transported on a cable system?
Reception. Nearly all cable TV systems carry subscription content that is relayed from a satellite in geosynchronous orbit. A device called a modulator at the local station’s facilities feed their programming over this line to the cable TV headend, which in turn receives it with another device called a demodulator.
What are cable nodes?
It has been commonly employed globally by cable television operators since the early 1990s. At the local community, a box called an optical node translates the signal from a light beam to radio frequency (RF), and sends it over coaxial cable lines for distribution to subscriber residences.
What is node to node delivery?
In telecommunications, node-to-node data transfer is the movement of data from one node of a network to the next. In most communication systems, the transmitting point applies source coding, followed by channel coding, and lastly, line coding. This produces the baseband signal.
What is a Ethernet node?
A node is an active device connected to the network, such as a computer or a printer. A node can also be a piece of networking equipment such as a hub, switch or a router. A bus topology consists of nodes linked together in a series with each node connected to a long cable or bus.
What is a cable node?
What is the download transmission frequency in CATV?
The CATV transmission system is connected to port 1 of the mux-demux. CATV signal consists of both analog and digital parts, and its bandwidth is 1 GHz.
What is a CATV node?
CATV Optical Receiver(Node) Cable television is a system of delivering television programming to paying subscribers via radio frequency (RF) signals transmitted through coaxial cables or, in the 2010s, light pulses through fiber-optic cables.
What is a node in Comcast?
A node is part of the Hybrid fibre-coaxial cable network. Specifically it is the part that translates between fiber and coax (light and RF) as fiber is used to extend the area that a single head end or hub can cover beyond what can be transmitted over RF on coax with amplifiers.
