Join Greg Sowell for an in-depth discussion in this video Dial-up, part of Foundations of Networking: Network Media (WANs).
- [Voiceover] If you are new to IT,…you've likely never experienced…the joys of hearing a modem screech while dialing up.…At its core, Dial-Up is using POTS…or the plain old telephone system…to connect to a remote network.…This connection is made via built in or external modem.…Modem stands for modulator demodulator.…It takes a digital signal,…modulates that to analog for transmission,…then reverses the process on the other end.…Modems were born out of a need to connect…teleprinters using standard phone lines.…
The term modem was coined in 1958…to describe the devices used to connect…the US SAGE missile defense devices together.…Modems are usually classified…by the amount of data they can transmit,…which is generally expressed as bits per second.…They can also be identified by their baud,…which is the rate at which they can send symbols.…Early modems had baud rates around 300 bits per second.…As microcomputers began to gain in popularity,…so did software controlled modems for them.…
This allowed the computer to send…
He discusses different WAN technologies and features such as speeds, spans, and price points—including inexpensive options such as VPN. He then covers switches (the devices that connect computers in your building) and routers (devices that control the transmission of network data). Along the way, Greg shows how to build private connections, implement free networking over the Internet, build switch networks, and overlay-routed networks. He'll also introduce different routing protocols, such as OPSF link-state routing and distance-vector routing with RIPv2, EIGRP, and BGP.
Note that this course maps to domains 1 and 2 of the Microsoft Technology Associate (MTA) Networking Fundamentals certification exam (98-366).
