Multiplexing is the process of combining 2 or more signals together into one multi-component signal with all signals being sent to the same receiver or receivers. Demultiplexing is the process of separating the multiplexed signal into its individual component signals. NOTE: The major distinction between multiplexing and multiple access is that in multiple access the signals are coming from many different sources and are going to many different destinations. Multiplexing is used to describe cases in which there is only one source and one destination for the many individual signals.
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 of multiple reasons why the 286 was considerably faster. In addition to a faster clock rate and more dedicated hardware for certain instructions, the 286 had separate address lines and instruction lines. The CPU didn't contain circuitry to switch between the signals and could do addressing and instructions at the same time, and the motherboard was somewhat simpler in that the latches and circuitry to sort the two types of information did not have to be as complex.

Why address and data lines are demultiplexed in 8085?
Basically , Demultiplexing is breaking of multiplexed signal .Recall that A/D0 -A/D15 and A16/S3-A19/S6 are the multiplexed signals in 8086.To do so, three demultiplexing latches are used .ALE (Address Enable Latch) is used for strobe Demultiplexing.8086 is 16bit data lines and 20 bit address line microprocessor.BY the Demultiplexing ,we Get A0-A19 separate Address lines and D0-D15 Data lines .

What is demultiplexing?
Demultiplexing is to separate 2 or more channels that have been multiplexed. Signals are typically multiplexed or combined onto one higher speed channel to efficiently use the bandwidth.
Why the name 8085 Why the name 8085 for microprocessor?

Why the 16 bit 8085 microprocessor is not possible?
The 8085 was replaced with the 8086/8088. As such, there is no 16 bit version of the 8085.
Difference between 8080 and 8085?
The 8085 has a single +5V power supplyThe 8085 has a multiplexed low order address busThe 8085 has extra single pin interrupts, TRAP, RST7.5, RST6.5, and RST5.5The 8085 has serial I/O pins SID and SODThe 8085 has maskable interrupts and the RIM/SIM instructionThe 8085 includes the functionality of the 8224 clock genereator and 8228 system controllerThe 8085 added several 16 bit operations
What is themeaning of pipe lines for 8085 microprocessor?
The 8085 is not pipelined.
