Ports Information Window
A pathway into and out of the system. Serial and parallel ports on a system are external sockets for plugging in communications lines, modems and printers. Every network card connects to the LAN using a port of some type. Any device that sends and receives data requires an available port to connect to each line.
Port Type | Examples of port type include serial port, parallel port, USB, and so on. |
---|---|
External Name | Name of the port, such as serial or parallel, USB, mouse, keyboard, and so on. |
Base I/O Addr | Starting input/output address expressed in hexadecimal. |
IRQ Lvl | An interrupt request (IRQ) is a hardware interrupt on a system. The hardware interrupt signals the system's CPU that an event has started or ended in a peripheral component such as a modem or printer. When communicated over a PCI card, the IRQ level is a standard way to identify the type of device that is sending the interrupt request. |
Connector Type | The type of plug or cable and plug that connects two devices together, in this case, the type of connector that attaches an external device to a system. Many connector types are available, each designed to connect a different device type to a system. Examples include DB-9 Male, AT, Access Bus, PS/2, and so on. |
Maximum Speed | Port speed refers to the data transmission rate of an input/output channel, measured in numbers of bits per second. Serial ports have an average speed of 115 Kbps and USB ports have an average speed of 12 Kbps. |
