	group to execute a certain task. From the user standpoint, a
	cluster acts as a large computer system.
Console Access Server	A CAS has an Ethernet LAN connection and many RS-232
(CAS)	serial ports. It connects to the console ports of servers and
	networking equipment and allows convenient and secure
	access from a single location.

	authenticate messages sent between an SNMP client and a
	router containing an SNMP server. The community name is

	time. Also used to refer to the keyboard, video and mouse
	user interface to a server.

DHCP	Dynamic Host Configuration Protocol. A protocol for
	automatic TCP/IP configuration that provides static and
	dynamic address allocation and management.
	DHCP enables individual computers on an IP network to
	extract their configurations from a server (the 'DHCP server')
	or servers, in particular, servers that have no exact
	information about the individual computers until they request
	the information. The overall purpose of this is to reduce the
	work necessary to administer a large IP network. The most
	significant piece of information distributed in this manner is
	the IP address.
