A browser is a software program that enables you to visit Web sites and view Web pages on your computer screen. Just as a word processor is the software you use to write letters and papers with your computer, a browser is the software you use to surf the Web. Once on a site, your browser translates HTML programming instructions sent over the Internet into the web pages you are accustomed to seeing. Some browsers offer more secure forms of encryption than other browsers do. Even the same version of a browser can come with different levels of encryption.
Encryption is the process of converting information into a more secure format for transmission.
In other words the plain text is converted to scrambled code while being transmitted, and then decrypted back to plain text at the receiving end of the transmission. It is comparable to writing a letter, converting it to code, putting it in an envelope and mailing it with the recipient descrambling the code. The 128-bit browser offers the highest level of encryption generally available in North America today and provides the best protection when transmitting confidential data over the Internet. When applying on-line your application is encrypted. The difference between these two types of encryption is one of capability.
