When it comes to selecting an appropriate DSL or Cable connection, there are a number of factors that one has to consider, for example, the speed or internet bandwidth and the popularity of use between the two. The internet bandwidth speeds for the two types of connectivity vary greatly in the Upper Marlboro area. A cable modem connection using the EarthLink Internet Company offers a peak of up to 15 Mbps (megabytes per second) for both the download and uploads speeds. This is slower compared to the DSL connection service offered by the same company. The DSL internet connection only provides up to 7 Mbps (megabytes per second) for downloads and uploads.

The logical implication in the above features is that the Cable modem connection is the most reliable since it has a higher bandwidth and dial up connection.
The Verizon Company and the XFINITY Internet Company do not offer both of the packages, but instead provide DSL and Cable modem services respectively. The most lucrative DSL package the Verizon Company provides is the Verizon High Speed Internet Enhanced package that has a maximum download speed of up to 15 Mbps (megabytes per second).

Transmitting high frequencies requires a wider frequency bandwidth at all times to enable successive data transmission. Additionally, running a DSL network can only be used for networks connected from a telephone switching station to an office or home network environment (Elahi, 2006).
