Mozilla Thunderbird

Thunderbird is a free, open source email, newsgroup, news feed and chat (XMPP, IRC, Twitter) client created by the Mozilla Foundation. The project stratagem is modeled after Mozilla Firefox, a project aimed at generating a Web browser. The vanilla version is not a personal information manager, although the Mozilla Lightning extension adds PIM functionality. Additional features, if desired, are often available thru other extensions. It supports UNIX mailbox format (mbox), Mork which is utilized for internal database and SQLite also used for internal database (since version 3). Files that bear the .p7s extension are email messages utilized in email managing programs for sending, receiving or just simply viewing protected emails encrypted with digital signatures. Some of these email management applications include Microsoft Outlook 2010, PostBox and Mozilla Thunderbird. These files contain information as well as the source of the email and whether the email has been edited or modified during transmission, which means users with these email management applications incorporated with P7S support can make sure that the emails they receive are genuine, are originating from trusted senders and are not tampered with, before they open and view the emails.

Microsoft Office

Microsoft Office is an office suite of desktop applications, servers and services, released by Microsoft on August 1, 1989 for the Microsoft Windows and Mac OS X operating systems. Originally, the first version of Microsoft Office contained Microsoft Word, a word processor and was previously considered the main program in Office; Microsoft Excel, a spreadsheet program that originally competed with the dominant Lotus 1-2-3; and Microsoft PowerPoint, a popular presentation program for Windows and Mac.; a marketing term for a bundled set of applications. As years passed by, Office applications have grown significantly closer with shared features such as a common spell checker, Object Linking and Embedding (OLE) data integration and Microsoft Visual Basic for Applications scripting language. Microsoft also positions Office as a development platform for line-of-business software under the Office Business Applications brand.
