Digital Electronics - Digital Concepts - Discussion

Transmisions are two types ie serial and parallel format.

From the question, serially transmitted means all data bits or all connection line are transmited by single wire ie single line. It take more time to transmitted the signal, so we better to use parallel format for transmission and parallel format is used number of input lines and it transmitted very fast and number of input lines are used in paralll format, it willnot take more time to compare with serial format. So finally parallel format is each digital signal has its own conductor. Parallel signal is digital signal.

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.

Data transmission can be done by two ways:

1) Serial - Here the data bits/bytes are queued up so that all the data can be transferred over a single data line. All the data can be sent, but transmission takes more time.

2) Parallel - Here number of lines are given depending on number of data bits.e.g. for hexadecimal numbers 0-F(0000-1111), four parallel transmission lines may be used. More number of data lines are needed, but data is sent almost simultaneously & speedily.

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.

----------------------
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.

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.

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.

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.

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

So every signals should have its own path/conductor.

I think parallel format means at one time many instructions are going to be executed like pipelined.
