Internet Connections Flashcards
How does home users, remote workers, and small offices connect to the Internet?
Typically require a connection to an ISP. Connection options vary between ISPs and geographical locations.
choices include: broadband cable, broadband digital subscriber line(DSL), wireless WANs, and mobile services
Typically offered by cable television service providers, the internet data signal transmits on the same cable that delivers cable television. It provides a high bandwidth, high availability, and an always-on connection to the internet.
What is it?
Cable
What runs over a telephone line?
In general, small office and home office users connect using Asymmetrical DSL (ADSL), which means that the download speed is faster than the upload speed.
DSL
What uses a cell phone network to connect?
Cellular
What benefit in those areas that would otherwise have no internet connectivity at all?
Satellite
What is an inexpensive option that uses any phone line and a modem. The low bandwidth provided by a dial-up modem connection is not sufficient for large data transfer, although it is useful for mobile access while traveling.
Dial-up Telephone
What are Leased lines are reserved circuits within the service provider’s network that connect geographically separated offices for private voice and/or data networking. The circuits are rented at a monthly or yearly rate?
Dedicated Leased Line
This is sometimes known as Ethernet WAN.
It extend LAN access technology into the WAN.
Metro Ethernet
It is a popular choice is Symmetric Digital Subscriber Line (SDSL) which is similar to the consumer version of DSL but provides uploads and downloads at the same high speeds.
Business DSL
It can provide a connection when a wired solution is not available?
Satellite
What is Traditional Separate Networks
thirty years ago. Back then, some classrooms were cabled for the data network, telephone network, and video network for televisions. These separate networks could not communicate with each other. Each network used different technologies to carry the communication signal. Each network had its own set of rules and standards to ensure successful communication. Multiple services ran on multiple networks.
What is Converged Networks?
Today, the separate data, telephone, and video networks converge. Unlike dedicated networks, converged networks are capable of delivering data, voice, and video between many different types of devices over the same network infrastructure. This network infrastructure uses the same set of rules, agreements, and implementation standards. Converged data networks carry multiple services on one network.
