Updating firmware on various consumer devices.Present in test and measuring equipment.For managing and configuring networking equipment such as routers, switches, etc.Various applications and devices which use the port are as follows:
The pins along with their functions and signal codes are as follows: PIN Besides, each pin uses different signals for its purpose. Furthermore, all these pins have different purposes.
Serial port serial#
Data through this port travels at the speed of 115 kilo-bits per second.īrowse more Topics under Input Output Ports/ ConnectionsĪs we know that usually there are 9 pins on a serial port. These ports have two available versions namely, the 9-pin and 25-pin model. Usually, external modems use these ports. The characteristics of a serial port are as follows: It is one of the oldest types of interfaces. Furthermore, we can identify this port from a D shape with usually 9 pins. Besides, these ports are usually present on the back of the computer and are part of the motherboard. Moreover, it generally denotes RA-232 or other related standards like RS-422, RS-485, etc. Serial PortĪ serial port carries out a serial communication interface and can transfer only one bit at a time. The ports are of different types as follows: Ports in other words are slots on the motherboard to which we connect the external devices. We use the ports to connect external devices like printers, USB, speakers, etc. Therefore, we connect these devices through the ports. Hence, it is important to take care that the data lines do not engage for a long time else it can affect the overall performance. Moreover, we know that the processing speed of the CPU and memory is much faster than the input/output devices. Besides, it can be of many types like serial port, parallel port, USB Port, etc. 7 Frequently Asked Questions (FAQs) PortsĪ port is basically an interface between the computer and the output devices like printer, speakers, mouse, etc.
