Search Engine
A directory of Internet content. Search engines use spiders
to search for Web pages, and then list those pages according to the
content they contain. When you use a search engine to find specific
information, the search engine provides a detailed list of Web pages
that best match your inquiry. Popular search engines include Excite,
Snap, Yahoo, and Infoseek.
Security Certificate
Information used to establish
a secure connection by SSL
protocol. In order for an SSL connection to be created, both sides
must have a valid Security Certificate, issued by the Certificate
Authority.
Server
A
computer or program that manages network
resources. The term can refer to a program, or to the machine on
which the program is running. A single server machine could be
running several programs, thus providing different services to users
on the network.
SMTP
Simple
Mail Transfer Protocol: A protocol used to send email from one
server to another.
Spam
(or Spamming)
Junk email
or junk newsgroup posts. Spam is usually some sort of advertising,
inappropriately sent to a mailing
list or newsgroup.
Spam not only wastes the recipient's time, but also misuses network
bandwidth.
Spider
An
Internet program (used by a search
engine) that explores
the Web at large. Spiders collect and index Web page addresses based
on content found at those pages.
SQL
Structured Query Language: A specialized programming
language used to send queries to databases. Many Web-based programs
use SQL to store and retrieve information about users and products
from databases.
SSL
Secure Sockets Layer: A protocol designed by Netscape to
enable encrypted communications across the Internet. It provides
privacy, authentication, and message integrity. SSL is often used in
communications between browsers and servers. A URL that begins with "https" indicates that an SSL
connection will be used on the Web page.
During an SSL
connection, each side sends a Security Certificate to the other. Both sides then encrypt what they
send, ensuring that only the intended recipient can decode it.
