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 ...
A single line that when active (logic zero) indicates the device is being written by the CPU. Byte enable (¯). A group of lines that indicate the size of the data (8, 16, 32, 64 bytes). The RD and WR signals of the control bus control the reading or writing of RAM, avoiding bus contention on the data bus. [1]
The bi-directional 8-bit data bus of the Intel 8080 is split into two unidirectional 8-bit data buses. The processor could use only one of these at a time. The Sol-20 used a variation that had only a single 8-bit bus and used the now-unused pins as signal grounds to reduce electronic noise. The direction of the bus, in or out, was signaled ...
Four PCI Express bus card slots (from top to second from bottom: ×4, ×16, ×1 and ×16), compared to a 32-bit conventional PCI bus card slot (very bottom). In computer architecture, a bus (historically also called a data highway [1] or databus) is a communication system that transfers data between components inside a computer or between computers. [2]
A system bus is a single computer bus that connects the major components of a computer system, combining the functions of a data bus to carry information, an address bus to determine where it should be sent or read from, and a control bus to determine its operation. The technique was developed to reduce costs and improve modularity, and ...
The physical layer transmits a 20-bit "phit" using a single clock edge on 20 lanes when all 20 lanes are available, or on 10 or 5 lanes when the QPI is reconfigured due to a failure. Note that in addition to the data signals, a clock signal is forwarded from the transmitter to receiver (which simplifies clock recovery at the expense of ...

In computing, an interface is a shared boundary across which two or more separate components of a computer system exchange information. The exchange can be between software, computer hardware, peripheral devices, humans, and combinations of these. [1]
