Use this window to view information about your system's ports for communicating with
peripheral devices and with other systems.
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.

Description |
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. |
