In this tutorial we will learn about bounded transmission medium in details. Pointtopoint transmission characteristics of guided media. In data communication terminology, a transmission medium is a physical path between the transmitter and the receiver i. A twisted pair cable is cheap as compared to other transmission media. Outside plant fiber optic cabling shall be composite design, fiber optic cabling with multimode and. Transmission media are the physical pathways guided or unguided that connect computers, other devices, and people on a network. Explain the characteristics of the popular guided transmission media.
Boundedguided transmission media in computer networks. Media access control address, 12 character number that identifies each network adapter. Transmission media transmission medium physical path. It is the most commonly used medium in the telephone network. Bound transmission media are the cables that are tangible or have physical existence and are limited by the physical geography. Digital transmission introduction data or information can be stored in two ways, analog and digital. Data is represented by computers and other telecommunication devices using signals. Bounded or guided transmission media in computer networks is the transmission media in which signals are confined to a specific path using wire or cable. Longhaul trunksincreasingly common in telephone network sprint ads. Difference between synchronous and asynchronous transmission transmission modes in computer networks simplex, halfduplex and full duplex. In this lesson, lets learn the types of transmission media and. Twisted pair is much less expensive than the other commonly used guided transmission media coaxial cable, optical fiber and is easier to work with.
The transmission media is nothing but the physical media over which communication takes place in computer networks. Twisted pair cabling is the most common used networking media in use today. Transmission media is broadly classified into two groups. It is also referred to as wired or bounded transmission media. Transmission media is also called communication channel. Transmission media is broadly classified into the following types. Twisted pair is a physical media made up of a pair of cables twisted with each other. Signals are transmitted in the form of electromagnetic energy from one device to another. By far the most common transmission medium for both analog and digital sig nals is twisted pair. It is defined as the physical medium through which the signals are transmitted. One of the most convenient way to transfer data from one computer to another, even before the birth of networking, was to save it on some storage media and transfer physical from one station to another. For longdistance applications, twisted pair can be used at data rates of 4 mbps or more. Can be minimized by proper shielding in guided media number of receivers in a shared link, each attachment introduces attenuation and distortion on the line guided transmission media transmission capacity bandwidth and data rate depends on distance and type of network pointtopoint or multipoint twisted pair least expensive and most. Transmission media 29 parabolic dish antenna, about 3m in diameter fixed rigidly with a focused beam along line of sight to receiving antenna with no obstacles, maximum distance.
