Fast user switching in Windows is based on Remote Desktop Services technology. [3] In Windows XP, GINA which is a component of Winlogon, and with which fast user switching interacts, can be programmatically called to automate a fast user switch. [4] A PowerToy known as Super fast user switcher was offered in 2002 by
A forwarding information base (FIB), also known as a forwarding table or MAC table, is most commonly used in network bridging, routing, and similar functions to find the proper output network interface controller to which the input interface should forward a packet. It is a dynamic table that maps MAC addresses to ports.
Before a register access, PHY devices generally require a preamble of 32 ones to be sent by the MAC on the MDIO line. The access consists of 16 control bits, followed by 16 data bits. The control bits consist of 2 start bits, 2 access type bits (read or write), the PHY address (5 bits), the register address (5 bits), and 2 "turnaround" bits.
The Individual Address Block (IAB) is an inactive registry which has been replaced by the MA-S (MAC address block, small), previously named OUI-36, and has no overlaps in addresses with the IAB [6] registry product as of January 1, 2014. The IAB uses an OUI from the MA-L (MAC address block, large) registry, previously called the OUI registry.
Windows 2000, for example, introduced support for displaying status messages (including verbose messages that can be turned on through Group Policy) about the current state to the user (e.g. "Applying computer settings."), and starting applications in the user's context; this facilitates restarting Windows Explorer automatically if it crashes ...
Switching loops can cause misleading entries in a switch's media access control (MAC) database and can cause endless unicast frames to be broadcast throughout the network. A loop can make a switch receive the same broadcast frames on two different ports, and alternatingly associate the sending MAC address with the one or the other port.
MACFF is described in RFC 4562, MAC-Forced Forwarding: A Method for Subscriber Separation on an Ethernet Access Network. Allied Telesis switches implement MACFF [1] using DHCP snooping to maintain a database of the hosts that appear on each switch port. When a host tries to access the network through a switch port, DHCP snooping checks the host ...
Aqua is the successor to Platinum, which was used in Mac OS 8, Mac OS 9, and developer releases of Rhapsody (including Mac OS X Server 1.2). The appearance of Aqua has changed frequently over the years, most recently and drastically with the release of macOS Big Sur in 2020 which Apple calls the "biggest design upgrade since the introduction of ...
