Serial port interfaces are not common as they used to be once. It is being replaced by USB- a modern method that does not need special knowledge. Modern computers have USB ports rather than Serial Port Interfaces. GPS receivers are being installed inside devices. It means there is no need for a cable connection. Our computer experts can deal with all kinds of problems and provide you the solution when you ask, "can you please do my assignment for me?".
Serial Port Versus Parallel Port
Parallel and serial ports are different kinds of computer ports. Compared to a parallel port, a serial port interface transfers data on a single line instead of several lines at one time bit by bit. The bit sequences are grouped into a data series that begins with a start bit and ends with a stop bit. Thus it has got the name “serial port.”
A serial port contains two lines via which the real data is transferred. These are the lines to transfer data from the PC to a communication device. Additionally, there are many control lines. For proper functioning, the serial ports depend on a controller chip, UART or Universal Asynchronous Receiver/ Transmitter that supports a high data transfer. Moreover, the UART controller changes a parallel code into a serial one and vice versa. These are explained in our Serial Port Interfacing assignment help service.
Where are Serial Ports used?
Serial ports are being used at a reduced rate because of the introduction of a more compact and faster USB interface. The external modems are rarely used. However, there are many specialized devices such as different barcode scanners, industrial equipment, surveillance cameras that depend on serial ports for connecting to a computer. It can be connected to multiple motherboards.
As there are a huge number of affordable software and hardware solutions developed for Serial ports, it is here to stay. In comparison to USB, it has an advantage. It can drive 15 meters of a shielded cable but the length of a USB cable is restricted to 5 meters.
