Parallel formats it is data transformation will very fast compare to serial formate because of data transformation only one time data transfer but parallel format data transformation at a time simultaneous.

i.e parallel format very useful now days. Because speed and reduced time.

What does parallel means?
Min Of 2 lines that never meet.

And what does a series connection mean?
One behind the other ie in a line.

The same goes for parallel connection ie data are sent independently and individually ie no of bits = no of lines for transmission, no traffic as single is transmitted over one line so transmission is faster, but it is suitable for small distance as because large the distance longer lines required Which add on to lines setup cost which is a disadvantage. Thank you.

Wire connector from input to the output, ie wire considered as a conductor.

Parallel format: At a time we will send the number of bits by using the number of paths (channels). Eg: We saw running competition, in that each runner will have desired path to run and to reach the destination.

So same concept we assume in communication tech, each channel or path called conductor in wired communication we will send the data by using metal wires (conductor)s only.

But why it is said conductor?

Parallel :: reaching or getting of many signals at a same time.

So every signals should have its own path/conductor.

In parallel format,each input(one of the digital signals to be transmitted) has its own path or line to transmit through it. So no of inputs has its own and separate line (i.e) it has its own conductors.

----------------------
The above is a single wire through which bits can be transmitted serially i.e., one bit at a time.

----------------------0000
----------------------1101
----------------------1010
----------------------0001
The above are four parallel lines through which hexadecimal number can be transmitted simultaneously. It saves time.

In serial format only one bit (digital signal) is transmitted at a time by means of single wire. Whereas in parallel format Group of bits is transmitted at a time by means of BUS (group of wires).

Hence each digital signal has its own conductor in parallel format.

It means conductor may be wired. In parallel transmission each data have own conductors.
