Opera is a web browser and Internet suite developed by the Opera Software company. The browser handles common Internet-related tasks such as displaying web sites, sending and receiving e-mail messages, managing contacts, chatting on IRC clients, downloading files via BitTorrent, and reading Web feeds. Opera is offered free of charge for personal computers and mobile phones.
Features of Opera include tabbed browsing, page zooming, mouse gestures, and an integrated download manager. Its security features include built-in phishing and malware protection, strong encryption when browsing secure Web sites, and the ability to easily delete private data such as HTTP cookies.
Opera runs on a variety of personal computer operating systems, including Microsoft Windows, Mac OS X,Linux, FreeBSD, and Solaris. Evaluations of Opera have been largely positive, and Opera has innovated many key features of modern browsers. Despite these factors, Opera has captured only a small fraction of the worldwide personal computer browser market. It does, though, have a stronger market share on mobile devices such as mobile phones, smartphones, and personal digital assistants. Editions of Opera are available for devices using the Symbian and Windows Mobile operating systems, as well as Java ME-enabled devices. Approximately 100 million mobile phones have been shipped with Opera pre-installed. Opera is the only commercial web browser available for the Nintendo DS and Wii gaming systems. Some television set-top boxes use Opera. Adobe Systems has licensed Opera technology for use in the Adobe Creative Suite.
