What are uart ports
What does a uart port means. I need some specific explanation of this. For what does this use for. Does it is the same serial port which we uses right now for printers or any other devices. I am not sure about the same. Because my cam is showing connection to uart port. I am not able to figure out this. What are the benefits of this ports.

Re: What are uart ports
All computer operating systems in use nowadays sustain and maintain serial ports, because serial ports have been approximately for decades. Parallel ports are a more current creation and are much faster than serial ports. USB ports are only a few years old, and will likely reinstate both serial and parallel ports totally over the next several years.

Re: What are uart ports
The name "serial" approach from the information that a serial port "serializes" data. That is, it takes a byte of data and broadcasts the 8 bits in the byte separately. The benefit is that a serial port requirements only one wire to broadcast the 8 bits (while a equivalent port requirements 8). The drawback is that it takes 8 times longer to broadcast the data than it would if there were 8 wires. Serial ports lower cable costs and make cables smaller.

Previous to every byte of data, a serial port propels a start bit, which is a single bit with a value of 0. After every byte of data, it propels a discontinue bit to signal that the byte is absolute. It may also propel a equivalence bit. Serial ports, also called communication (COM) ports, are bi-directional. Bi-directional communication permits every device to receive data as well as broadcast it.

Serial devices make use of dissimilar pins to obtain and broadcast data, using the similar pins would frontier or bound the communication to half-duplex, meaning that information in sequence could only travel in one direction at a time. Using dissimilar pins permits for full-duplex communication, in which information can travel in both directions at once.

This 40-pin Dual Inline Package (DIP) chip is a dissimilarity of the National partially performer NS16550D UART chip. Serial ports rely on a particular or extraordinary controller chip, to function correctly. The UART chip takes the equivalent output of the computer's system bus and renovates it into serial form for transmission through the serial port. This shock absorber permits the chip to accumulation data coming in from the system bus while it is dispensation data going out to the serial port.
