Glossary
	PPP has been a widely-used Internet standard for sending
	datagrams over a communications link. The PPP standard is
	described in RFC 1661 by the Point-to-Point Working Group
	of the Internet Engineering Task Force (IETF). PPP is
	commonly used when remote computers call an Internet
	service provider (ISP) or a corporate server that is configured
	to receive incoming calls.
Profile	Usage setup of the ACS either as a Console Access Server
	(CAS), a Terminal Server, or a Remote Access Server.
RADIUS	Remote Authentication Dial-In User Service is a client/server
	protocol and software that enables remote access servers to
	communicate with a central server to authenticate dial-in
	users and authorize their access to the requested system or
	service. RADIUS allows a company to maintain user profiles
	in a central database that all remote servers can share.
RISC	Reduced Instruction Set Computer. This describes a computer
	processor architecture that uses a reduced set of instructions
	(and achieves performance by executing those instructions
	very fast.) Most UNIX servers (Sun Sparc, HP, IBM RS6000,
	Compaq Alpha) were designed with a processor using a
	RISC architecture. The Intel ® x86 architecture.
Root Access	Root is the term for a very highly privileged administrative
	user (particularly in unix environments). When an ISP grants
	you root access, it means you will have full control of the
	server. With full control, you will be able to install any
	software and access any file on that server.
Routing Table	The Routing Table defines which interface should transmit an
	IP packet based on destination IP information.
Secure Shell (SSH)	SSH has the same functionality as Telnet (see definition for
	Telnet), but adds security by encrypting data before sending
	it through the network.
