Most signals are transmitted on a bus which is, as you might imagine, a "highway" for information. A serial bus is a single "lane" that has a control structure at each end to control what information gets to travel down the bus next and sends the information to the correct device at the end. A parallel busis like a multi-lane highway. Information is sent all at once. Usually parallel interfaces try to have enough "paths" for the information so that all the information can be transmitted simultaneously.

What are the advantages and disadvantages of parallel and serial data transmission?
big advantage of parallel transmission is the factor of speed. All else being equal, parallel transmission can increase the transfer speed by a factor of n over a serial transmission. But there is also a very significant disadvantage of parallel transmission. And that is the factor of cost. It can be proved from the fact that the parallel transmission requires 'n'
Which communication is faster in parallle and serial?
Parallel data transmission is faster compared to serial data transmission. The speed of a parallel link is equal to the number of bits sent multiplied by the bit rate of each individual path.
What is meant by serial and parallel transmission?
A serial port only allows a single bit of data through at a time. A parallel port allows multiple bits of data through at a time.
As we know parallel transmission is faster then serial then why serial is replacing parallel?
There is a greater risk of errors with parallel transmission because especially over longer distances, the bits may arrive at the destination at different times and therefore corrupting the data. Because serial transmission sends each bit one at a time, they always are received in order. Speed of transmission is not always the driving priority, if the information cannot be reliably transferred to the destination all the speed in the universe is useless.
Does the parallel transmission needs multiple communication lines?
Yes. 'Serial' transmission means all bits travel the same channel, one at a time. 'Parallel' transmission means several bits travel several channels, at the same time.
What is difference between a parallel bus and a serial bus?
A Parallel bus has a relatively large number of wires bundled together that enable data to be transferred in parallel. This increases the throughput, or rate of data transfer, between the peripheral and the computer. A Serial bus can be defined as a transmission path over which the participants transmit their data serially, sequentially in time, and using a common medium. In the case of serial transmission, only a single communication link for transferring data from any given end to another one. In the case of parallel transmission, we use multiple numbers of parallel links for the simultaneous transmission of all the data bits in the network.
What are the examples of serial and parallel ports?
give the difference between serial port and parallel port
What does Invisible queue means?
USB, Serial, and Parallel are all examples of which of the following?
What is the difference between serial and parallel data transmission?
one bit at a time vs. a group of several bits at a time.
Depends, is the device serial or parallel?
Depends, is the device serial or parallel?
How many feet is a parallel cable?
Parallel port communication cable length 8 channel is easy to form the mutual interference between the transmission speed and distance are limited, and when the transmission error, at the same time to the eight bits of data, and a serial port without interference, transmission error after it is ok to resend a, so faster than parallel port. Therefore generally parallel communication without transmission distance, serial communication, serial port communication is generally not more than 30 meters, but also the specific see the baud rate of the transmission signal, so the parallel communication estimated only a few meters, there is no exact definition of data.
Which is quicker serial or parallel?
parallel
