An internet service provider is delivering service through a copper medium with shared customer bandwidth. Which of the following services has most likely been installed?
DSL, unlike cable, provides a continuous, dedicated connection to your business, meaning the connection is not being shared among any potential neighbors.
Definitely cable, since it says that its a shared line.
The correct answer is D. DSL (Digital Subscriber Line).
The description matches the characteristics of DSL:
· Copper medium: DSL uses copper wires to deliver internet service.
· Shared customer bandwidth: DSL is a shared bandwidth service, meaning multiple customers share the same bandwidth.
Here's why the other options are unlikely:
A. Fiber: Fiber-optic connections use light to transmit data through glass or plastic fibers, not copper.
B. Cable: Cable internet uses coaxial cables, which are different from copper wires.
C. NIC (Network Interface Card): A NIC is a hardware component that connects a computer to a network; it's not a type of internet service.
DSL is a common internet service delivered through copper wires, making it the most likely option in this scenario.
Cable internet service also commonly utilizes copper coaxial cables to deliver internet service. This technology, known as Cable Internet, is distinct from DSL. Cable Internet typically offers higher speeds than DSL and is often provided by cable television companies. It also involves shared customer bandwidth, similar to DSL.
So, both DSL (option D) and Cable (option B) involve the use of copper mediums with shared customer bandwidth. However, DSL specifically refers to Digital Subscriber Line technology, while Cable refers to cable internet service.
Given this clarification, either option D (DSL) or option B (Cable) could be the correct answer, depending on the specific context of the question. Both technologies utilize copper mediums with shared customer bandwidth, but they operate differently and are provided by different types of service providers.
Cable internet services often use a copper infrastructure, and the bandwidth in this type of connection is shared among multiple users in a given area. In contrast, DSL (Digital Subscriber Line) typically provides dedicated connections for each customer, as mentioned earlier.
In summary, if the bandwidth is shared among multiple users in an area, the most likely option is cable internet service.
The coax cable has a copper core (like DSL). Unlike DSL, it is shared among multiple customers in a neighborhood. The bandwidth may vary depending on the network congestion.
This is tricky and I am wondering if something is missing in the question. The fact that is says it is delivered over a copper medium would make me think DSL. Then it mentions shared bandwidth. Bandwidth is not shared with DSL but is is shared with cable which is why people always saw their internet speeds drop between the hours of 5 and 10pm. Usually cable uses a hybrid network consisting of fiber to the node then delivers service from the node to multiple customers over copper. Considering that, I will have to go with B, cable as the answer.
Copper cabling is one of the three types of physical media used for the transmission of information over data networks. The Physical Layer of the OSI Model defines the types of cabling used, and how information is encoded on to that cable. Copper cabling comes in many forms.
