Lab 9 The Internet
9.1.1 Broadband Internet
The original dialup connections offered by telephone companies required complete use of the telephone cable to connect to the Internet (meaning that no calls could be placed or received during the Internet connection). Why is this inefficient for establishing a connection to the Internet? What was the limitation of the data rates available on this type of Internet connection?
First you had to make sure that your call waiting feature was turned off so that there wouldn’t be any interruptions in the service. Because it was like using the telephone, your data rates were charged as long distance telephone calls by the minute.
9.1.2
The term broadband Internet generally refers to higher-speed and constantly available connections to the Internet. The term represents an evolution of Internet connectivity, but it originally referred to the type of media usage. Broadband and baseband are the two types of media usage available. Briefly define these terms and explain the difference between them.
Broadband – The term broadband commonly refers to high-speed Internet access that is always on and faster than the traditional dial-up access. It also includes several high-speed transmission technologies such as Digital Subscriber Line (DSL) Cable Modem.
Baseband – refers to the original frequency range of a transmission signal before it is converted, or modulated, to a different frequency range.
The difference between baseband and broadband is that baseband uses digital signaling, and broadband uses analog signals in the form of optical or electromagnetic waves over multiple transmission frequencies.
