The following diagram shows a scenario where an Ethernet-connected ADSL modem acts as a PPPoE-to-PPPoA protocol converter and the service provider offers a PPPoA service and does not understand PPPoE. There is no PPPoEoA in this protocol chain. This is an optimally protocol-efficient design for a separate ADSL modem connected to a router by ...
A computer network diagram is a schematic depicting the nodes and connections amongst nodes in a computer network or, more generally, any telecommunications network. Computer network diagrams form an important part of network documentation.
A CSU/DSU can have an external connection point or it can be integrated into a modular card installed in a router. A CSU/DSU is the equivalent of the modem for an entire LAN. The DCE, commonly a modem or CSU/DSU, is the device used to convert the user data from the DTE into a form acceptable to the WAN service provider transmission link. [1]
A modem and router work in tandem to deliver you an internet connection and then grant access to your various devices. Modem vs. router: The differences between the pieces of hardware that connect ...
A switch can be connected to a router, cable modem, or ADSL modem for Internet access. LANs at residential homes usually tend to have a single router and often may include a wireless repeater. A LAN can include a wide variety of other network devices such as firewalls, load balancers, and network intrusion detection. [5]
However, a modem generally provides few other network functions. A USB modem plugs into a single PC and allows a connection of that single PC to a WAN. If properly configured, the PC can also function as the router for a home LAN. An internal modem can be installed on a single PC (e.g. on a PCI card), also allowing that single PC to connect to ...
Like SLIP, this is a full Internet connection over telephone lines via modem. It is more reliable than SLIP because it double checks to ensure Internet packets arrive intact. [4] It resends any damaged packets. PPP was designed somewhat after the original HDLC specifications. The people who had designed PPP included many additional features ...
Routers perform the traffic directing functions on the Internet; data packets are forwarded through the networks of the internet from router to router until they reach their destination computer. Routing algorithms determine the specific choice of route. Each router has a prior knowledge only of networks attached to it directly.
