A binary object file format defined by that is used to represent client programs in OF for PA. FDISK Refers to the boot-record and partition table format used by MS-DOS, as defined in . gateway Network connecting device host A computer. In particular a source or destination of messages from the point of view of the communication network. ICMP Internet Control Message Protocol IETF Internet Engineering Task Force IP Internet Protocol IO Input/Output LAN Local Area Network NVRAM Non-volatile memory that is the repository for various platform, OF and OS information that remains persistent across reboots, power management activities and/or cycles.
