CABLE INTERNET MODEM DEFINITIONS
A cable modem is a special type of modem that is designed
to modulate a data signal over cable television infrastructure.
The term cable Internet access (or simply cable) refers to
the delivery of Internet service over this infrastucture.
Cable modems should not be confused with older LAN systems
such as 10base2 or 10base5 that used coaxial cables — and
especially not with 10broad36, which actually utilized the
same sort of cable as CATV systems.
CABLE MODEM FOR BROADBAND INTERNET
Cable modem for broadband Internet accessCable modems are
primarily used to deliver broadband Internet access, taking
advantage of unused bandwidth on a cable television network.
Along with digital subscriber line technology, cable modems
ushered in the age of broadband Internet access in developed
countries. Prior to the availability of such systems, Internet
access involved slow dial-up access over a public switched
telephone network. Users in a neighborhood share the available
bandwidth provided by a single coaxial cable line.
CABLE INTERNET MODEM CONNECTION SPEED
Therefore, connection speed can vary depending on how many
people are using the service at the same time. Often the idea
of a shared line is seen as a weak point of cable Internet
access. From a technical point of view, all networks, including
DSL services, are sharing a fixed amount of bandwidth between
a multitude of users — but because cable networks tend to
be spread over larger areas than DSL services, more care must
be taken to ensure good network performance. A more significant
weakness of cable networks using a shared line is the risk
of loss of privacy, especially considering the availability
of hacking tools for cable modems.
