DNS (Domain Name System)
The Domain Name System is a system of mapping Domain Names to IP addresses. Because domain names are alphabetic, they are easier for humans to remember. The Internet, however, is really based on IP addresses. Every time you use a Domain Name, DNS translates the name into the corresponding IP address. It is similar to a phonebook for the Internet.

Internet
A global network linking millions of computers for communications purposes. The Internet was developed in 1969 for the U.S. military and gradually grew to include educational and research institutions.

Phishing
Phishing is a name derived from the notion of "fishing for information", and "phreaking", which was an eighties term used for people who hacked phone networks and systems to gain access to free calls, or control over parts of the telephony system. It is a simple concept, which is to try to trick people into disclosing their bank account details, so that the attacker may then log in to the person's Internet bank and withdraw their savings.

SSL (Secure Socket Layer)
Secured Sockets Layer is a protocol that transmits your communications over the Internet in an encrypted form. SSL ensures that the information is sent, unchanged, only to the server you intended to send it to. Online banking sites always use SSL technology to safeguard your personal information.
