1.4.4 Network Station Terminology
The following are definitions of terms that are used throughout this redbook.
Kernel (or operating system)
Both terms are used to refer to the IBM Network Station operating
system which consists of a small, multi-tasking, UNIX-derivative
kernel. It provides X Window support and also recognizes a limited
set of commands to run built-in applications. Numerous extensions
and libraries provide modular functionality for emulators, browser,
console, ICA client, and so on.
Flash memory cards
PCMCIA cards which normally vary in memory capacity sizes from
8MB to 32 MB (or 40MB in the near future). These cards can be
loaded with the IBM Network Station operating system kernel, files,
and applications. They are also often referred to as Flash, Flash
memory or Flash card.
Flash boot (or Flash memory boot)
Normally used interchangeably to refer to the process of loading an
IBM Network Station from a PCMCIA Flash memory card.
Peer boot
Process through which an IBM Network Station containing a loaded
Flash memory card can be used to boot other IBM Network Stations
on its own subnet network.
