then executing them

Anonymizer sites access the Internet on your behalf, protecting your personal information

from disclosure. An anonymizer protects all of your computer\’s identifying information while

it surfs for you, enabling you to remain at least one step removed from the sites you visit.

You can visit Web sites without allowing anyone to gather information on sites visited by

you. Services that provide anonymity disable pop-up windows and cookies, and conceal

visitor\’s IP address.

These services typically use a proxy server to process each HTTP request. When the user

requests a Web page by clicking a hyperlink or typing a URL into their browser, the service

retrieves and displays the information using its own server. The remote server (where the

requested Web page resides) receives information on the anonymous Web surfing service

in place of your information.

In which situations would you want to use anonymizer? (Select 3 answers)

A. Increase your Web browsing bandwidth speed by using Anonymizer

B. To protect your privacy and Identity on the Internet
