The RapidIO architecture is a high-performance packet-switched electrical connection technology. It supports messaging, read/write and cache coherency semantics. Based on industry-standard electrical specifications such as those for Ethernet, RapidIO can be used as a chip-to-chip, board-to-board, and chassis-to-chassis interconnect.
Multibus was an asynchronous bus that accommodated devices with various transfer rates while maintaining a maximum throughput. It had 20 address lines so it could address up to 1 Mb of Multibus memory and 1 Mb of I/O locations. Most Multibus I/O devices only decoded the first 64 Kb of address space.
Memory-mapped I/O is preferred in IA-32 and x86-64 based architectures because the instructions that perform port-based I/O are limited to one register: EAX, AX, and AL are the only registers that data can be moved into or out of, and either a byte-sized immediate value in the instruction or a value in register DX determines which port is the source or destination port of the transfer.
This is a list of interface bit rates, is a measure of information transfer rates, or digital bandwidth capacity, at which digital interfaces in a computer or network can communicate over various kinds of buses and channels.
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]

As tested by the Bus Research and Testing Center in Altoona, a 40-foot (12.2 m) battery-electric bus, with a gross capacity of 444 kW-hr (355 kW-hr usable) at 750 VDC, achieved a range of 129 to 187 mi (208 to 301 km), depending on the driving cycle (Manhattan and EPA HD-UDDS, respectively; the Orange County cycle fell in between).
The VESA Local Bus (usually abbreviated to VL-Bus or VLB) is a short-lived expansion bus introduced during the i486 generation of x86 IBM-compatible personal computers.Created by VESA (Video Electronics Standards Association), the VESA Local Bus worked alongside the then-dominant ISA bus to provide a standardized high-speed conduit intended primarily to accelerate video (graphics) operations.
