IS Keyboard serial or parallel

Answer 1

Oh, dude, keyboards these days use serial communication. Like, back in the day, parallel keyboards were a thing, but now it's all about that serial connection. So, yeah, if you're talking about modern keyboards, they're serial.

Answer 2

As the names imply, a serial port sends data on a small number of wires (often just two wires for the actual data), one bit after the other. A parallel port has many more wires used for data transmission, so many bits can be transmitted simultaneously. The big downside for a serial port is that the "bandwidth" (data bits per second) is very low compared to a parallel port running at the same rate.

BUT....parallel data busses have a problem. Electromagnetic interference causes "crosstalk" between the different bits on different data signal lines, and the faster the data rate, the worse the problem gets. Crosstalk causes data transmission errors to occur (a bad thing). So it can actually be a better solution to run a serial data connection at a very, very fast speed than to use a parallel data bus that will have to run at a lower speed (or use more expensive cables and circuitry).

In order to do this, each end of the computer bus will use a chip that contains a serial/parallel conversion circuit (SERial/DESerial, or SERDES). This allows the computers to operate on many bits in parallel (byes, words, etc.) but still transmit them in serial over a relatively cheap cable with high data rates.

Answer 3

there is no difference!! if you ask me it doesnt matter what keyboard you get they all do the same job, all have the same letters and numbers. but your not asking me your asking the person that has the best answer! all im saying is that all keyboards are good.

Answer 4

A keyboard is a serial due to it's typing ability in orange
