Question

When communicating with other devices , particularly in serial or parallel ports, why are data or number types are important to establish?

Answer 1

And It is very important while communicating with other devices in Serial or parallel port. Data can either be transmitted from One device to another device in digital Oy analog manner. In case of Serial data communication, data can only be Sent one after another, for that data are in a line or in a specific order. This one is an efficient and reliable method of data transmission because in this case there is no any chances of data overlapping or data redundancy as this will work, only when the data is single.

In parallel transmission process data bits are transferred much faster than that of serial data transmissioon . It is used when a large amount of data to be sent: A Parallel port requres multiple data lines in their cables and port connectos which are connected with both The ends of Input ie sender and the output le revieve
