Cable internet, or broadband as it's frequently called, uses the cable television infrastructure lines to bring internet access locally to a home or company. Today, it is the most popular way to obtain internet access because it is considerably faster when compared to a dial-up connection provided by a telephone land line.
Cable internet service utilizes a shared line which gives service to a whole neighborhood. When there are lots of people on the net simultaneously, it can easily slow up the transfer of data. Also, security measures are needed because it is possible for anyone on a single LAN (local area network) line gain access to someone else's data, if they understand how to do it. Most cable companies have addressed this concern with firewall functionality and modems that apply the Data Over Cable Service Interface Specification (DOCSIS). This supports cable network security.
