What is the minimum category of UTP cable that supports gigabit speeds?
Category 5e cable is now the minimum recognized cable for data networking applications, as defined by the current standard. Like Category 5 cable, it also is rated for up to 100 MHz frequencies. Additional performance standards enable it to support transmission speeds of up to 1000 mbps (“gigabit Ethernet”).
What is the purpose of the layer 2 LLC sublayer?
What is the purpose of the Layer 2 LLC sublayer? It is used to handle multiplexing, flow and error control, and reliability.
What is the maximum category of UTP cable?
Twisted pair cables Categories UTP Category Purpose Transfer Rate Category 6a Data Upto 10 Gbps Category 7 Data Upto 10 Gbps Category 7a Data 40 to 100 Gbps Category 8 Data 25 to 40 Gbps.
What Ethernet standard below is also referred to as thinnet?
What Ethernet standard below is also referred to as “thinnet”? 10Base2.
What are the four category of UTP cable?
Unshielded Twisted Pair (UTP) cable is most certainly by far the most popular cable around the world.
What is UTP cable used for?
UTP cables are mostly used for LAN networks. They can be used for voice, low-speed data, high-speed data, audio and paging systems, and building automation and control systems. UTP cable can be used in both the horizontal and backbone cabling subsystems.
What is LLC sublayer?
The LLC sublayer provides multiplexing mechanisms that make it possible for several network protocols (e.g. IP, IPX and DECnet) to coexist within a multipoint network and to be transported over the same network medium. It can also provide flow control and automatic repeat request (ARQ) error management mechanisms.
What is LLC and MAC sublayer?
Logic Link Control (LLC) Layer and Medium Access Control (MAC) layers are the sublayers of the Data link layer in the OSI reference model. OSI is a 7 layer architecture which contains 7 layers. Each layer has its own specific functionality. All these 7 layers in the OSI model are used to transmit data.
What does the LLC sublayer do quizlet?
The LLC sublayer takes the network protocol data, which is typically an IPv4 packet, and adds control information to help deliver the packet to the destination node. The LLC is used to communicate with the upper layers of the application, and transition the packet to the lower layers for delivery.
What is the maximum cable length for both Category 5e and Category 6 UTP cable?
Standards for cable distance recommend that Cat5, 5e, and 6 cables have a maximum cable segment run length of 100m or 328 feet. Four pairs of twisted wires are used to construct Category 5, 5e, 6, and 6a cable, which is most commonly unshielded, as in UTP.
What is the maximum speed supported by Category 5 UTP cable?
The Cat5 cable has a maximum speed of 100 Mbps and a bandwidth of up to 100MHz. Cat 5 can carry both telephone and video signals.
What are the different categories of UTP cables then and now?
Types of UTP cables CAT3: Rarely used today, CAT3 is usually deployed in phone lines. It supports 10 Mbps for up to 100 meters. CAT4: Typically used in token ring networks, CAT4 supports 16 Mbps for up to 100 meters. CAT5: Used in Ethernet-based LANs, CAT5 contains two twisted pairs.
What is the IEEE standard for Poe group of answer choices?
IEEE 802.3AF standard that specifies a method for supplying electrical power over twisted-pair Ethernet connections.
What protocol replaces ARP and icmpv4 on IPv6 based networks?
In IPv6, the Address Resolution Protocol (ARP) has been replaced by the Neighbor Discovery Protocol (NDP).
Which statement accurately describes what near end crosstalk next is?
Which statement accurately describes what near end crosstalk (NEXT) is? NEXT is crosstalk that occurs between wire pairs near the source of a signal.
What UTP means?
UTP stands for Unshielded Twisted Pair. In the mantle of a UTP cable you will find eight separate wires. All the wires are twisted in four pairs. A connector can be placed on the end of these cables. These connectors are also known as RJ45 plugs.
Which organization established the UTP cable categories?
The tighter the twisting, the higher the supported transmission rate and the greater the cost per foot. The EIA/TIA (Electronic Industry Association/Telecommunication Industry Association) has established standards of UTP and rated six categories of wire (additional categories are emerging).
What is UTP cat6?
CAT6A U/UTP means the cable consists of 4 unshielded twisted pairs and no outer shielding. CAT6A F/UTP means the cable consists of 4 unshielded twisted pairs however it contains an outer foil shield. This is a shielded cable. These features typically increase the outer diameter of the cable.
What is a FTP cable?
The term FTP stands for foil twisted pairs. FTP networking cables often support Ethernet LAN. Twisting the cores together and covering with the foil shield helps to reduce cross–talk and electromagnetic interference.
What is UTP cables are also known?
It is common for people to call UTP cables, Ethernet cables, because all networks follow the IEEE standards for Ethernet cabling. The original Ethernet standard was developed by Xerox in the 1970s.
What is Cat 6 UTP cable used for?
“A Cat6 cable is used mainly for computer networks reaching a GB, 1000 Mbps or one Gbps of data transfer speed (DTR) or higher,” says Techopedia.
What is the logical layer?
The logical layer determines the logical transmission paths between sources and destinations. The physical layer is responsible for sending packets from one end to the other end of the logical link. That is to say, the real packet transmission process is in the physical layer.
What is LLC sublayer characteristics?
It provides the logical addressing required that identifies the device. It provides delimitation of data according to the physical signaling requirements of the medium.
What is the role of the LLC sublayer in datalink layer?
Logical Link Control (LLC) sublayer provides the logic for the data link. Thus, it controls the synchronization, flow control, and error checking functions of the data link layer. Media Access Control (MAC) sublayer provides control for accessing the transmission medium.
