What is the difference between multiplexing and demultiplexing?
Multiplexing is the process of combining 2 or more signals togetherinto one multi-component signal with all signals being sent to thesame receiver or receivers. Demultiplexing… is the process ofseparating the multiplexed signal into its individual componentsignals. NOTE: The major distinction between multiplexing andmultiple access is that in multiple access the signals are comingfrom many different sources and are going to many differentdestinations. Multiplexing is used to describe cases in which thereis only one source and one destination for the many individualsignals. In an 8086, the address and instruction lines use the same wires,and a pin on the CPU toggles between those two uses. That is one ofmultiple reasons why the 286 was considerably faster. In additionto a faster clock rate and more dedicated hardware for certaininstructions, the 286 had separate address lines and instructionlines. The CPU didn't contain circuitry to switch between thesignals and could do addressing and instructions at the same time,and the motherboard was somewhat simpler in that the latches andcircuitry to sort the two types of information did not have to beas complex.
email@example.com ---- The differences between these two circuits is subtle, as far as I can tell. A demux simply selects an output line, nothing more. It…'s a glorified switch. A decoder takes n inputs, and uses those inputs to determine which of the 2^n output lines is high. This is the difference, I think. A decoder is designed to simply keep one line high. A demux is designed to set one output equal to the input (whether it be high, low, or a changing signal).
A decoder takes n inputs and produces 2^n outputs. An encoder takes 2^n inputs and produces n outputs. A multiplexer selects one line from many lines. The inverse of s…election is distribution. A demux essentially transmits data from one line line to 2^n possible output lines. The output line is determined by n select lines. In short, a multiplexer selects an input line, a demultiplexer selects an output line. The differences between these two circuits is subtle, as far as I can tell.

A multiplexer, commonly referred as an input selector, is a circuit with many inputs but only one output: it has some data inputs, control inputs and one output, depending… on the control inputs, one input from the data inputs is sent to the output .A demultiplexer is a circuit with one data input, few control inputs and many outputs, it is also known as output selector.
Decoder convert an input binary code into a corresponding single active output. you can think of a Multiplexer (switch) as your home systems-it connects data from one of n so…urces to its output.when you want play movie you select movie on your home system then it switch it to movie..
Modulation is the way a source of information transmits that information through a carrier. For example, look at human speech. A person, the source of information, transmits… data by modulating the air with sound waves in a way that is understandable to other humans. In this case the air is the carrier. Multiplexing is when many slower data lines (CAT5, POTS, etc.) are combined into a single faster data line (T1, Optical Fiber). An example is the communications backbone between two cities. A fast, high bandwidth optical line joins the cities together, but when it reaches either city's limits, it is split up into many individual phone or data circuits. The bottom line is that modulation is how a source manipulates the carrier where as multiplexing is combining multiple circuits into a single, faster line and then separating them again.
An encoder refers to a device that is used to change a signal or data into a code. Whereas a Multiplexer or mux is a device which performs multiplexing or it takes information… from more than one channels and outputs into a single channel. Thus a multiplexer is basically a kind of encoder where its function is to combine multiple inputs into one output.
A multiplexer takes many inputs and and selectively allow one output. A demultiiplexer is just the opposite function
MODEM or modulation and demodulation perform that function a multiplexer is used to select and service any modem on line
Well, Multiplexers called MUX is generally an electronic device that is used to select multiple line input to single line output. It has n input lines and 1 output lines. It c…an be used when parallel input has to be converted into serial output lines. from the n lines one of them gets through the output line at a time. it is also provided with selection lines which select the particular input to output. De multiplexer is such a device that is just reverse of the MUX. It has 1 input line and n output lines. Selection lines determine which of the n lines to be selected for output

A multiplexor is a device that takes two or more signals and encodes them on fewer (often, on one) wire. A demultiplexor is a device that reverse that process.
Segmentation is the division of packets across the network for example from Location A to location B , and multi plexing is the interleaving of pieces when transversing trough… different media
Multiplexing-Combining all the inputs into one output. Switching-Taking one input to the output, at a time/frequency
Time Division Multiplexers are a bit historical but here's an answer. A number of channels are required to be assembled onto an aggregate. Thirty 64 kbit/s channels could go …onto a 2 Mbit/s aggregate for example. A multiplexer is constructed to a standard such as G.700 series in the ITU-T. In the same box a de-multiplexer is constructed to decode the received 2 Mbit/s. Also a manufacturer could decide to build a proprietary standard of his own. Timeplex were good at this and made excellent systems with benefits over CCITT later ITU-T standard. Advantages were being able to mix data at different bit rates and also include voice, compressed or not compressed, with or without signalling - if needed. Multiplexers could form meshed networks rather that A-B dumb-bell links and these may need management to sneak in and out of them. Time Division Multiplexers did what they say, the interleaved the data for each channel or tributary so that it could be received and broken out at the far end. Each channel had its own slot on the frame of the system and came around in a rate which enabled the original bandwidth and clock to be recovered and presented in just the right interface.
