What network cable contains a glass or plastic core?
Modern Data Wiring Has Come A Long Way Today’s data wiring networks use rely on two primary technologies: ethernet cables comprised of twisted copper conductors and fiber optic cables comprised of glass or plastic cores.
Which of the following is most commonly used client/server network topology?
Star topology is by far the most common. Within this framework, each node is independently connected to a central hub via a physical cable—thus creating a star-like shape. All data must travel through the central node before it reaches its destination.
In which topology are all computers connected via a single cable?
A bus topology exists when all of the nodes on the network are connected to a single cable. This single cable is commonly referred to as a backbone.
Is a set of rules for exchanging communications?
protocol, in computer science, a set of rules or procedures for transmitting data between electronic devices, such as computers. In order for computers to exchange information, there must be a preexisting agreement as to how the information will be structured and how each side will send and receive it.
What are the 4 types of network cables?
The Four Types of Network Cabling Coaxial Cable. Coaxial cables have a single copper conductor at the center, while a plastic layer provides insulation between the center conductor and braided metal shield. Fiber Optic Cable. Shielded Twisted Pair (STP) Cable. Unshielded Twisted Pair (UTP) Cable.
What kind of network cable is most commonly used?
Unshielded twisted pair UTP cable is the most popular type of network cable. It is easy to work with, install, expand and troubleshoot. UTP cables typically contain four pairs of copper wires, with each pair containing two wires twisted together.
Which topology is best for LAN?
Star topology has become the dominant physical topology for LANs.
Which network cable is most susceptible to interference?
Unshielded Twisted Pair (UTP) cables are more prone to the signals from their lines interfering with each other. Compared to UTP, Shielded Twisted Pair cable provides additional safeguards against interference. With greater cable interference protection, higher transmission rates over longer distances can be supported.
Which type of topology is best suited for large business?
Explanation: The star topology is the best network topology for large businesses because it is simple to control and coordinate from the central computer.
Which of the following is the most expensive network of topology?
Star topology is the most popular way to connect a computer in a workgroup. It is expensive due to the cost of the hub. Star topology uses a lot of cables, which makes it the most costly network to set up as you also have to trunk to keep the cables out of harm.
Which topology has the highest reliability?
Mesh topology: In this, each device has a dedicated point to point link to every other device. Dedicated means that a link carries traffic only between two devices it connects. It is the most reliable topology.
Which topology is most fastest topology?
Theoretically the fastest topology should be mesh topology. But the best topology is star topology. In star topology devices are connected to the center switch or hub and all interconnection between them are done through that center hub.
What type of cable is not subject to EMI?
Answer: True. Fiber cable is not susceptible to signal loss from electromagnetic interference (EMI) or radio frequency interference (RFI). Two common sources of EMI are from electric power cables or fluorescent light fixtures that are too close to signal cables.
What sends data between two networks?
A bridge sends information between two networks.
What are protocols?
A protocol is a set of rules and guidelines for communicating data. Rules are defined for each step and process during communication between two or more computers.
What is the 3 types of cable?
Fiber optic cable, twisted pair cable, and coaxial cable are the three main types of network cables used in communication systems. Each of them is different and suitable for various applications.
Which of the following cable types is the least expensive?
Although UTP cable is the least expensive cable, it may be susceptible to radio and electrical frequency interference (it should not be too close to electric motors, fluorescent lights, etc.).
Which cable is used for Internet?
Ethernet cables connect computers in a Local Area Network, or LAN, within a small area such as a business, college campus or even your home. The wireless router common in many homes is connected to an Ethernet cable from the internet provider.
What are the types of cables?
Cables are classified into 5 types depending upon their purpose as follows: Ribbon Electric Cables. It consists of multiple insulated wires running parallel with one another and is used for transmission of multiple data simultaneously. Shielded Cables. Twisted Pair Cables. Coaxial Cables. Fibre Optics Cable.
Which cable is used in LAN?
There are two main types of LAN cable. One is the standard straight through cable, usually known as Ethernet patch cable, which is used for connecting computers to routers or switches. Note that, common Ethernet cable comes in STP and UTP patch cable with a variety of grades as the following table shows.
What type of cable that has a thicker?
Multimode fiber optic cables have thicker core diameters (typically 50µm) than single-mode cables.. These thicker fibers allow the cable to carry light of various modes at 850 to 1300nm wavelengths.
What topology is expensive to set up and maintain?
Mesh topology is time consuming, expensive, and sometimes gives redundant connections. The mesh layout is hugely complex and is difficult to set up, manage, and maintain.
What WAN stands for?
Wide Area Network (WAN).
Which cable is used in mesh topology?
Summary Chart Physical Topology Common Cable Common Protocol Linear Bus Twisted Pair Coaxial Fiber Ethernet Star Twisted Pair Fiber Ethernet Tree Twisted Pair Coaxial Fiber Ethernet.
Which cable type is most vulnerable to EMI?
UTP cabling is most susceptible for EMI. Fiber Optic is least susceptible.
Which cable is most susceptible to echo?
It is important to note that twisted -pair is the networking -cable type most susceptible to attenuation, which is why its maximum distance is 100 meters (328 feet).
Which cabling technology is the most susceptible to electromagnetic interference?
Since unshielded twisted pair cabling has no foil shield and relies on the way the pairs inside the cabling are twisted, it is more susceptible to electromagnetic interference in industrial settings. UTP is a good choice for CAN systems and similar network cabling systems.
