Safari is a web browser from Apple. The browser is suitable for the operating systems Mac OS X, Microsoft Windows, and for Apple's iPhone and iPod Touch. Since Mac OS X 10.3 (Panther), Safari has been a standard part of Mac OS X. The browser navigates with tabs and blocks pop-ups. The Snap Back feature lets users quickly jump back to previously visited and highlighted websites.
Safari also supports Hypertext Markup Language( HTML 5) audio and video tags, which can be used to insert media directly into websites. With HTML 5 offline technology, Safari stores information from web-based applications locally on a hard drive, so applications can run without an active connection to the web.
To protect a user's privacy, Safari offers a private browsing feature. This no longer logs which websites were visited or which files were downloaded. Search queries on Google, cookies or data that a user enters into online forms are also no longer stored during private browsing.
If Safari notices a possible phishing attack or malware when a suspicious website is requested, the user is automatically warned. Homepages with EV Certificates (Extended Validation) are visually highlighted by Safari. Eavesdropping and forgery attempts as well as digital manipulation are made more difficult or prevented by encrypting the transmitted data.
Safari also presents websites on Apple's iPhone and iPod touch multi-touch devices. The basis of the mobile version is provided by "WebKit", a technology for displaying graphics, rendering fonts and determining page layout.
On the iPhone or iPod touch, a website is customized and formatted to fill the iPhone or iPod touch window horizontally or vertically. Clippings can be zoomed in or out with two fingers. The built-in reader displays RSS feeds and Atom feeds without images. Complex, multi-column web pages are analyzed by the Safari browser and when the user clicks on a column, the browser zooms into that column so that it is displayed legibly.
