These are dedicated lines used to coordinate data transfer. They are used to signal ready/not ready, or to acknowledge or request. This back and forth handshaking is needed in async comms to avoid sending data until the receiver is ready for it.
The MPU and peripherals operate at different speeds, the MPU being faster than the peripherals(like printers and data converters). To avoid overlapping of data during data input (by preventing MPU reading same data twice before i/p peripheral writes next data) or data output (by preventing MPU from writing over the data before o/p device has had a chance to accept it), handshake signals are used between MPU & the peripherals. These signals are generally provided by programmable devices.

Why FDM is for analog signals and TDM is for digital signals?
FDM stnds for frequency division multiplexing and it is used only in case of analog signals because analog signals are continuous in nature and the signal have frequency. TDM-stands for time division multiplexing and it is used only in case of digital signals because digital signals are discrete in nature and are in the form of 0 and 1s. and are time dependent.
A device that conveys information with analog signals and digital signals is called?
An Electronic Device
What converts digital signals into analog signals for use with IDSN?
it is an DAC (Digital to analogue converter
Difference between inband and out of band signaling?
In in- bandsignalling , the control and management signals travles along with the data signals where as in out of band signalling the data and control signals travels in different channels
How do you find RMS Error Between Two Signals?
I have two Different Signals, I would like to find the RMS Error Between them, and Mathematically derive how the signals differ from each other. I would like to find the RMS Error for the two Signals. Please Help. Thanks in Advance.
