What Does it mean by Multiplexing? 

when we send Multiple Flow of Data over a Single Link so is it Possible To send Multiple user data Using Only single link Yes Guys it is Possible There is Some Algorithms By Using These Algorithms we will able to send Multiple user Data over a single link.

Frame: It,s just define boundary of The data that from which point our Data is starting and which time it will end ……..simple if you have some data like “”start10000000end”” so this called one frame

TDMA: Time division multiple access Technology Mostly used in Digital Communication in This Technique we allot Time slot to the Frames(packets) in which time which frames will be transmitted. e.g suppose we have three frames A,B,C so 1 sec is The quantum time for the frames when A transmit after one second B will Transmit when B Transmitted and after one second The C will transmit……it,s all about time slot …Present zong mobilink telenor use this TDMA Technique

FDMA: Frequency Division Multiplexing  Access The same Technique but we allot Different Frequencies to The signals To use One Single Link and Get More advantage For example A signal 10khz For signal B 15khz for C 20 khz ……Best example is The cable Tv one coxable line coming to The Tv and you can watch 150+ channels ..
CDMA : Code Division Multiplexing Access Technology in This Technology we allot Different pattern of Codes to The signals which allow user to Send his data More securely and at More Efficient way Because Every user have a unique pattern of code only reviver will understand The data no third party interact in his data  For example signal A (1001) signal B (1111) signal C (1100) ..This method is more Effiecent Then TDMA FDMA ……….3G and 4G use this Method
