A port expander is a device that allows one port on a computer system to connect to multiple devices. Two basic forms of port expander exist: internal and external. An internal expander has a connection inside the computer, typically on the motherboard, and the only part the user sees is the expansion plate containing multiple ports. An ...
A four-port "compact design" USB hub: upstream and downstream ports shown. A USB hub is a device that expands a single Universal Serial Bus (USB) port into several so that there are more ports available to connect devices to a host system, similar to a power strip. All devices connected through a USB hub share the bandwidth available to that hub.
The CardBus expansion card standard is an evolution of the PC card standard to make it into a compact version of the PCI bus. The original ExpressCard standard acts like it is either a USB 2.0 peripheral or a PCI Express 1.x x1 device. ExpressCard 2.0 adds SuperSpeed USB as another type of interface the card can use.
Computer port (hardware) A computer port is a hardware piece on a computer where an electrical connector can be plugged to link the device to external devices, such as another computer, a peripheral device or network equipment. [1] This is a non-standard term. Electronically, the several conductors where the port and cable contacts connect ...
The port numbers in the range from 0 to 1023 (0 to 2 10 − 1) are the well-known ports or system ports. [3] They are used by system processes that provide widely used types of network services. On Unix-like operating systems, a process must execute with superuser privileges to be able to bind a network socket to an IP address using one of the ...
Port multiplication. A Serial ATA port multiplier is a unilateral splitting device. While it allows one equipped port to connect up to 15 disks, the bandwidth available is limited to the bandwidth of the link to the controller, as of 2012 1.5, 3, or 6 Gbit/s. [3] While the controller is aware that there are multiple drives connected, the ...
The clock port is a commonly used term for the real-time clock interface of the Amiga 1200 computer. The port is a remnant of an abandoned design feature for addition of internal RAM and a clock for time keeping. However, it was later widely used as a general purpose expansion port by third-party developers for devices, such as, I/O cards ...
Other ports on the Corps of Engineers list include the Port of Houston in the number one spot. South Louisiana is second, then Corpus Christi; New York/New Jersey; Long Beach, California; New Orleans; Beaumont and Baton Rouge. As of May 2024 the Port of Lake Charles surged to the number 10 on the list below. [2]
