What is a network?🤷and how it works and what are the parts of network?

Network,when you buy a new computer,the first thing you will probably try to do is connect to the internet. to do this you establish a connection to your rowter which recives the data from the internet and then forwards it to do the computer.and these process called network. Now how to communication using the internet-(1)TWISTED PAIR CABLE-Ttisted pair cabling is a type of wiring in which two conductors of a single circuit are twisted electromagnatic compatibillity.

(2)COAXIAL CABLE- these cables are insulated star lines,who was able to send data at high rate.in the center they had a copper wire,that was coverd with pvc insulationane copper mesh was twesed on them.then this shield was cowerd with seacond outer pvc shield.

(3)OPTICAL FIBER-optical fiber like a hair or a pakastic wire,that trancemetion the data like copper wire.they are do light transmet expect electrical signal.beacuse light work faster expect electricete.

at the top of the opticalfiber tranmition there had a dayod that used for releasing the light and there had some deceters at the receving end for indentify the signal (4)MICROWAVE TRANSMISSION-this is also a nice tranemetiocn medeam.this is famous for data recive,becauseit does not require laying cables.for the data transmet in microwave system there had used high freq.but this communition had in "line of sight",because the signal gets weaker whiletravelling longer distance.therefor,to amplify the signal reapeaters are installed at the distance of 20-30 KM.

in the microwave system signal gets transmet at 16 giga bits per second and itr anoter point is on that time thousands of chanel gets on its high rate installation. (5)COMMUNICATION SATELITE-There has a less of microwave system that earths curicul,hills and any obstruction line of sight was stop.and they insall the reapeters for other obstruction,then therefor communication between dots.satelite communication was usefull for realising.

HINDI-satellite bhi buniyadi toor per ek microwave station ha jo outer sace me place kiya jata ha.yesatelliterocket dwara launch kie jate ha and ye middle line se 36000 kh per place haye transponder jo satellite per mount hote ha aur kamjor signal ko amplify karke jamin per wapas bhejta ha.ek transponder 1200 voice chanel sport karta ha.ek satellite me kai transponder lage hote ha.is parkar ek satallite me bhout data communication ki yogyata hoti ha.
