IO-Link is a short distance, bi-directional, digital, point-to-point, wired (or wireless), industrial communications networking standard (IEC 61131-9) used for connecting digital sensors and actuators to either a type of industrial fieldbus or a type of industrial Ethernet. [1]
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.
Comparison of the I/O memory management unit (IOMMU) to the memory management unit (MMU).. In computing, an input–output memory management unit (IOMMU) is a memory management unit (MMU) connecting a direct-memory-access–capable (DMA-capable) I/O bus to the main memory.
CXL.io – based on PCIe 5.0 (and PCIe 6.0 after CXL 3.0) with a few enhancements, it provides configuration, link initialization and management, device discovery and enumeration, interrupts, DMA, and register I/O access using non-coherent loads/stores.
Connection-oriented communication; Blocking or Nonblocking read and write (choosable) Standard device I/O handles (ReadFile, WriteFile) Namespace used to create handles; Inefficient WAN traffic (explicit data transfer request, unlike e.g. TCP/IP sliding window, etc.) Peekable reads (read without removing from pipe's input buffer)

MII has two signal interfaces: A Data interface to the Ethernet MAC, for sending and receiving Ethernet frame data. A PHY management interface, MDIO, used to read and write the control and status registers of the PHY in order to configure each PHY before operation, and to monitor link status during operation.
