This allows for placing and replacing the central processing unit (CPU) without soldering. Common sockets have retention clips that apply a constant force, which must be overcome when a device is inserted. For chips with many pins, zero insertion force (ZIF) sockets are preferred. Common sockets include pin grid array (PGA) or land grid array ...
IEEE 802.1ag is an amendment to the IEEE 802.1Q networking standard which introduces Connectivity Fault Management (CFM).This defines protocols and practices for the operations, administration, and maintenance (OAM) of paths through 802.1 bridges and local area networks (LANs).
In Solaris/OpenSolaris, the loop device is called "loopback file interface" or lofi, [2] and located at /dev/lofi/1, etc. SunOS has the configuration program lofiadm. lofi supports read-only compression and read-write encryption. Available is also a 3rd-party driver fbk (File emulates Blockdevice), for SunOS/Solaris since summer 1988. [3]
