Ports Information Window

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.
