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.
An IO-Link master can be either a stand-alone slave or part of a modular slave device. An IO-Link-to-Sercos mapping guide [13] is available to assist manufacturers in integrating IO-Link into a Sercos III network. An IO-Link development board with an IO-Link master and a Sercos III slave interface is available.
Generally, layers are named by their specifications: [8] 10, 100, 1000, 10G, ... – the nominal, usable speed at the top of the physical layer (no suffix = megabit/s, G = gigabit/s), excluding line codes but including other physical layer overhead (preamble, SFD, IPG); some WAN PHYs (W) run at slightly reduced bitrates for compatibility reasons; encoded PHY sublayers usually run at higher ...
However, since IEEE 802.3 (Ethernet) and IEEE 802.4 (Token Bus) send the bytes (octets) over the wire, left-to-right, with the least significant bit in each byte first, while IEEE 802.5 (Token Ring) and IEEE 802.6 (FDDI) send the bytes over the wire with the most significant bit first, confusion may arise when an address in the latter scenario ...

The serial gigabit media-independent interface (SGMII) is a variant of MII used for Gigabit Ethernet but can also carry 10/100 Mbit/s Ethernet. It uses differential pairs at 625 MHz clock frequency DDR for TX and RX data and TX and RX clocks. It differs from GMII by its low-power and low pin-count 8b/10b-coded SerDes. Transmit and receive path ...
With 28 years of experience in early learning, Wilma Tom Hashimoto, executive director of CASA of Fresno and Madera counties, vies for seat on Clovis Unified board.
Metcalfe subsequently co-founded 3Com in 1979. [1] The other co-founders were Metcalfe's college friend Howard Charney and two others. [1] Bill Krause joined as President in 1981 and became CEO in 1982 and led 3Com until 1992 when he retired. 3Com began making Ethernet adapter cards for many early 1980s computer systems, including the DEC LSI-11, DEC VAX-11, Sun-2 and the IBM PC.
