What is a bit?

Bit Stop is a character in an asynchronous communication that allows the receiver to know that the transmitted byte has ended. This is essential for the way most of the information is transmitted over the Internet. Without a stop bits, it is possible that the receiver's computer would probably call on an error message and make further communication with a problematic computer.

Asynchronous communication means that data is transmitted without any external hours. The receiving computer therefore requires knowing when the byte ends up to "prepare" for the acceptance of another byte. In addition to the bits of the stop, another piece of the start -up puzzle is signaling the beginning of new information. The bytes usually include eight bits of data plus the initial bit and stop bit for a 10 -liter character frame. These bytes are then assembled to present data in their origin context. The bytes can be part of a computer program or something as simple as words in an e-mail.

curiously, while Start and Stop Bit are usually associated with modern technology, including the latest data transfer, these two terms have their roots in older communication technologies. For example, telethype machines at the end of the 19th and early 20th century had to be resynchronized after the beginning of each character called codes. These codes could often include more than one word. After the transmission of each code, a bit would also be transferred with a stop that would indicate that it was time to resynchronize.

In some cases, older telethype machines may require more than one bit. However, no more than one bit is needed in modern asynchronous communication. This can confuse some computer users who come across Windows Configuration Panel, especially on computers with older operating systems. A countless options are submitted, most of which make sense according to today's data transfer standards.

If for data data receiving computer is not PA stop bit of a stop, probably an error message appears. This error is called framing error and can be caused by the fact that the bytes are not correctly formatted. It may require the attention of IT professional. Usually, the framing error is a sending machine error, not acceptance, although it is possible that signal degradation can also cause framing error.
