Pegasus Mail
Pegasus Mail is a proprietary email client developed by David Harris (who also develops the Mercury Mail Transport System). It was originally released in 1990 for internal and external mail on NetWare networks with MS-DOS and later Apple Macintosh clients. It was subsequently ported to Microsoft Windows, which is now the only platform actively supported. Previously freeware, Pegasus Mail is now donationware. The early versions of Pegasus were installed on MS-DOS or Mac workstations on a Netware network, and supported only mail between network users; for external (Internet) the Mercury Mail Transport System for Netware was required. Features Pegasus Mail (PMail) is suitable for single or multiple users on stand-alone computers and for internal and Internet mail on local area networks. Pegasus Mail has minimal system requirements compared with competing products, for instance the installed program (excluding mailboxes) for version 4.52 requires only around 13.5 MB of hard drive s ...

Donationware
Donationware is a licensing model that supplies fully operational unrestricted software to the user and requests an optional donation be paid to the programmer or a third-party beneficiary (usually a non-profit). The amount of the donation may also be stipulated by the author, or it may be left to the discretion of the user, based on individual perceptions of the software's value. Since donationware comes fully operational (i.e. not crippleware/freemium) when payment is optional, it is a type of freeware. History An example of donationware is the 1987 Atari ST video game ''Ballerburg'', whose programmer distributed the game for free but asked for a donation, offering as incentive the source code for the game. on e ...

Mbox
Mbox is a generic term for a family of related file formats used for holding collections of email messages. It was first implemented in Research Unix, Fifth Edition Unix. All messages in an mbox mailbox are concatenated and stored as plain text in a single file. Each message starts with the four characters "From" followed by a space (the so-called "From_ line") and the sender's email address. RFC 4155 defines that a UTC timestamp follows after another separating space character. A format similar to mbox is the MH Message Handling System. Other systems, such as Microsoft Exchange Server and the Cyrus (imapd), Cyrus IMAP server, store mailboxes in centralized databases managed by the mail system and not directly accessible by individual users. The maildir mailbox format is often cited as an alternative to the mbox format for networked email storage systems. Mail storage protocols Unlike the Internet protocols used for the exchange of email, the format used for the storage of em ...

Message Handling System
Message Handling System (MHS) is an important early email protocol developed by Action Technologies, Inc. (ATI) in 1986. Novell licensed it in 1988 then later bought it. Email clients A wide variety of email clients used MHS, including: * Para-Mail - Paradox Development introduced version 2.0 along with Novell at Comdex 1986. * DaVinci Email - The first Microsoft Windows-based email client used MHS natively. * Pegasus Mail - A free mail client, this used MHS its native protocol. * ExpressIT! and ExpressIT! 2000 - Infinite Technologies' MHS compliant email clients. * FirstMail - A cut-down version of Pegasus Mail, bundled with some versions of NetWare. * Futurus TEAM - Early groupware package offering an MHS compliant email client. * MacAccess - An Apple Macintosh MHS-based email client. Role as a gateway MHS was a very 'open' system, and this, with Novell's encouragement, made it popular in the early 1990s as a 'glue' between not only the proprietary email systems of the da ...

Email Attachment
An email attachment is a computer file sent along with an email message. One or more files can be attached to any email message, and be sent along with it to the recipient. This is typically used as a simple method to share documents and images. History, and technical detail Originally, ARPANET, UUCP, and Internet SMTP email allowed 7-bit ASCII text only. Text files were emailed by including them in the message body. In the mid 1980s text files could be grouped with UNIX tools such as bundle and shar (shell archive) and included in email message bodies, allowing them to be unpacked on remote UNIX systems with a single shell command. The COMSYS/MSGDMS system at MIT offered "Enclosures" beginning by 1976. Users inside COMSYS could receive the enclosure file directly. Messages sent to users out of the COMSYS world sent the enclosure as part of the message body, which was useful only for text files. Attaching non-text files was first accomplished in 1980 by manually encoding 8-bit f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
JavaScript
JavaScript (), often abbreviated as JS, is a programming language that is one of the core technologies of the World Wide Web, alongside HTML and CSS. As of 2022, 98% of Website, websites use JavaScript on the Client (computing), client side for Web page, webpage behavior, often incorporating third-party Library (computing), libraries. All major Web browser, web browsers have a dedicated JavaScript engine to execute the Source code, code on User (computing), users' devices. JavaScript is a High-level programming language, high-level, often Just-in-time compilation, just-in-time compiled language that conforms to the ECMAScript standard.

ActiveX
ActiveX is a deprecated software framework created by Microsoft that adapts its earlier Component Object Model (COM) and Object Linking and Embedding (OLE) technologies for content downloaded from a network, particularly from the World Wide Web. Microsoft introduced ActiveX in 1996. In principle, ActiveX is not dependent on Microsoft Windows operating systems, but in practice, most ActiveX controls only run on Windows. Most also require the client to be running on an x86-based computer because ActiveX controls contain compiled code. ActiveX is still supported as of Windows 10 through Internet Explorer 11, while ActiveX is not supported in their default web browser Microsoft Edge (which has a different, incompatible extension system, as it is based on Google's Chromium project). ActiveX controls ActiveX was one of the major technologies used in component-based software engineering. Compared with JavaBeans, ActiveX supports more programming languages, but JavaBeans supports mor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malware
Malware (a portmanteau for ''malicious software'') is any software intentionally designed to cause disruption to a computer, server, client, or computer network, leak private information, gain unauthorized access to information or systems, deprive access to information, or which unknowingly interferes with the user's computer security and privacy. By contrast, software that causes harm due to some deficiency is typically described as a software bug. Malware poses serious problems to individuals and businesses on the Internet. According to Symantec's 2018 Internet Security Threat Report (ISTR), malware variants number has increased to 669,947,865 in 2017, which is twice as many malware variants as in 2016. Cybercrime, which includes malware attacks as well as other crimes committed by computer, was predicted to cost the world economy $6 trillion USD in 2021, and is increasing at a rate of 15% per year. Many types of malware exist, including computer viruses, worms, Trojan horses, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Browser Engine
A browser engine (#Name and scope, also known as a layout engine or rendering engine) is a core software component of every major web browser. The primary job of a browser engine is to transform HTML documents and other resources of a web page into an interactive visual representation on a User (computing), user's device. Name and scope A browser engine is not a stand-alone computer program but a critical piece of a larger program, such as a web browser, from which the term is derived. The word "software engine, engine" is an analogy to the engine of a car. Besides "browser engine", two other terms are in common use regarding related concepts: "layout engine" and "rendering engine". In theory, layout (computing), layout and wikt:rendering, rendering (or "painting") could be handled by separate engines. In practice, however, they are tightly coupling (computer programming), coupled and rarely considered separately. In addition to layout and rendering, a browser engine enforces t ...

HTML
The HyperText Markup Language or HTML is the standard markup language for documents designed to be displayed in a web browser. It can be assisted by technologies such as Cascading Style Sheets (CSS) and scripting languages such as JavaScript. Web browsers receive HTML documents from a web server or from local storage and render the documents into multimedia web pages. HTML describes the structure of a web page semantically and originally included cues for the appearance of the document. HTML elements are the building blocks of HTML pages. With HTML constructs, images and other objects such as interactive forms may be embedded into the rendered page. HTML provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists, links, quotes, and other items. HTML elements are delineated by ''tags'', written using angle brackets. Tags such as and directly introduce content into the page. Other tags such as surround ...
