TRANSMISSION MEDIA , ANALOG VS DIGITAL DATA TRANSMISSION



INTRODUCTION
The transmission medium is the physical path between the transmitter and receiver in a data transmission system.
Transmission media is divided into two types: Guided(wired) or Unguided(Wireless).
Wired Media is the most common and is further divided into three different types of cabling: Coaxial, Twisted Pair, and Fiber Optic Cables
Wireless media, which is, in a sense, no media ....etc

Definition

Internet is a network of networks in which various computers connect each other through out the world. The connection to other computers is possible with the help of ISP (Internet Service Provider). Each Internet users depend dialup connections to connect to Internet. This has many disadvantages like very poor speed, may time cut downs etc. To solve the problem, Internet data can be transferred through Cable networks wired to the user computer. Different type connections used are PSTN connection, ISDN connection and Internet via C ....etc

The High frequency attenuation in shielded distribution cable has been extensively studied. But in the case of solid dielectric cable, this has not been done. A solid dielectric cable has a bit more complex structure including the semiconducting “bedding” layers and a moisture barrier.high frequency loss is created by these sources.The purpose of these bedding layers is to seal the cable against moisture ingress and also accomodate for the thermal expansion of the cable. The cables studied here are the ones with a corrugated copper sheat ....etc

A large interest in renewable energy systems has been developed to mitigate the green house effect. In Western Europe, the focus is thus, on wind power and especially on offshore locations, due to higher energy production, a longer expected life time and lack of suitable wind turbine sites on land. A DC cable is the preferred choice when connecting large offshore wind farms to the grid. The utilization of the Dc cables was enabled by the new HVDC transmission technology using voltage sourced converters. The offshore windfarms that are being bui ....etc

Using Telephone and Cable Networks for Data Transmission

TELEPHONE NETWORK
Telephone networks use circuit switching. The telephone network had its beginnings in the late 1800s. The entire network, which is referred to as the plain old telephone system (POTS), was originally an analog system using analog signals to transmit voice.
