2.7 Compare and contrast Internet connection types, network types, and their features. Flashcards
We sometimes refer to this as broadband communication because we are sending information over many different frequencies on the same wire.
cable modem/DOCSIS (data over cable service interface specification)
This is the standard that is used on cable networks to send data across to these cable modems. This is what we consider high-speed networking. These cable networks can go very high speeds. Very commonly you’ll find four to 250 megabits per second, but you can get up to gigabit speeds running on these cable modem connections.
DOCSIS (data over cable service interface specification)
Very commonly your local telephone company is providing connectivity through ___ connections.
DSL (digital subscriber line) aka ADSL (asymmetric digital subscriber line)
What does DSL connectivity require?
Close proximity to a telephone central office.
These are rarely used in homes anymore but may be seen in enterprises in case of remote internet disconnection.
dial up modems
What is the difference between dial-up and DSL?
Dial up uses a dial up model to use telephone cables to access the phone company’s internet via DSL, but is very slow.
DSL directly connects to a central office but requires very close proximity to the office.
DSL is also known as a __ communication
Broadband.
A ___ is a device that enables a computer to send or receive data over telephone or cable lines. Its main function is to convert digital signal into analog and vice versa.
Modem
This connection type has better HD channel connectivity than you might have with a copper-connected service. And this also allows you to send and transfer a lot of different types of data out to the cloud. You might also see enhanced capabilities with DVR and video capabilities using this high bandwidth connection type.
fiber
This networking type has a relatively high cost but would allow you to connect to the internet without a dial up modem. Has slower upload speed than download.
satellite networking
There are a number of challenges with satellite networking. One of these is that you have a relatively high ___. It does take time to get that data up to a satellite and then back down to earth.
latency
ISDN stands for what and means what?
Integrated services digital network. An older style of internet connectivity that is an alternative to VoIP.
These networks have many different antennas set up in a geographical area where the land is separated into cells. Requires an antenna to connect.
cellular
Not only do our mobile phones have internet connectivity, but we can connect a wire from a laptop to our mobile phone and provide the laptop with the internet connectivity as well. That’s called ___.
tethering
What is the difference between tethering and hot spots?
Tethering is using a mobile device to provide cellular connection via a direction connection such as a USB, while hotspot is a wireless access point provided by mobile device allowing wireless cellular network connection for other devices.
