Master/slave: A situation in which a client machine (the slave) is

tied to a large server (the master). No matter how intelligent the
client may be, it is never called upon to think for itself. It does
only what the master tells it to. Mainframes sending displays to
dumb terminals is the classic master/slave relationship; large
servers on the Internet sending Hypertext Markup Language
(HTML) pages to the browser window on a PC is another.

Multitenant: The use of a server in a cloud to provide computer
services to more than one customer. Also, the use of an applica-
tion in the cloud to provide services to more than one customer,
such as Salesforce.com customer relationship management
(CRM). A multitenant application needs a greater ability to
scale up for many users than the standard business application.

Open source code: A method of developing code through a col-
laborative, voluntary group process in which the resulting
application or piece of software is made freely available through
download over the Internet.

Peer to peer: A pattern of computing in which two computers
interact, and the intelligence at each end of the interaction

comes fully into play without one assuming dominance over
the other. The opposite of master/slave computing.

Perl: A scripting language designed to manage servers and
used by system administrators; often invoked to tie together
diverse elements on a Web site.
