Basic networking concepts ppt
Crosstalk is interference from adjacent wires. FireWire has two standards: To do this, you would not be able to use a straigh-through cable because the transmit pin on one computer would be connected to the transmit pin on another. Figure displays these two connector styles. There are two types of coax cabling:

Baseband communication baasic Mbps transfer rate Maximum distance of meters per network segment 30 hosts per segment 0. The 10BaseT Ethernet architecture runs at 10 Mbps and uses baseband transmission.
Baseband communication is also bidirectional, which means that the same channel can be used to send and receive signals. FireWire has two standards: There are two fibers per cable—one to transmit and one to receive.
RS The standard for serial connections using the serial port on a computer. Coaxial Cable Coaxial cable or coax carries signals of higher frequency ranges than those in twisted pair cable, in part because the two media are constructed. We think you have liked this presentation.

Table summarizes the characteristics of thicknet and thinnet. This architecture supports distances up to 3 kilometers. We have discussed coaxial cabling, and you saw the BNC connector that goes on the end of the cable and connects to the network card, but there are a few other BNC connector types you should be familiar with. Type A connectors connect to the computer, whereas Type Conccepts connectors connect to the device.
Basic Network Concepts:
Around that strand is a layer of insulation, and covering that insulation is braided wire and metal foil, which shields against electromagnetic interference. Networks Terminology and Hardware.
All systems will look at the data, but they will not process it, since it is not destined for comcepts. The ring is the internal communication path within the wiring. This can be accomplished either by assigning a frequency for sending and assigning a frequency for receiving along the same cable or by using two cables, one for sending and one for receiving. Chapter Objectives Provide a background on Ethernet itself and describe its characteristics Explain the practical.
The answer networkung determined by three major access methods: Broadband Sends information in the form of an analog signal, which flows as electromagnetic waves or optical waves. The core also can be an optical-quality clear plastic, and the cladding can be made up of gel that reflects signals back into the fiber to reduce signal loss.
Baseband Sends digital signals through the media as a single channel that uses the entire bandwidth of the media. Fiber-optic cables are also highly secure from outside interference. Token Ring uses the token-passing access method.
An access method determines how a host will place data on the wire—does the host have to wait its turn or can it just place the data on the wire whenever it wants? Auth with social network: There conncepts two types of coax cabling: Chapter Objectives Describe the characteristics of different LAN topologies —Bus, ring, star and mixed topologies Compare and contrast.
The reason this network architecture appears to use a star topology is that all hosts are connected to a central device that looks similar to a hub, but with Token Ring, this device is called a multi-station access unit MAU or MSAU. Twisted-pair cabling gets its name by having four pairs of wires that are twisted to help reduce crosstalk or interference from outside electrical devices.
Each category of UTP concwpts was designed for a specific type of communication or transfer rate. The signal is delivered as a pulse of electricity or light, depending on the type of cabling being used.
