Freeware is software, most often proprietary, that is distributed at no monetary cost to the end user. There is no agreed-upon set of rights, license, or EULA that defines freeware unambiguously; every publisher defines its own rules for the freeware it offers. For instance, modification, redistribution by third parties, and reverse engineering are permitted by some publishers but prohibited by others. Unlike with free and open-source software, which are also often distributed free of charge, the source code for freeware is typically not made available. Freeware may be intended to benefit its producer by, for example, encouraging sales of a more capable version, as in the freemium and shareware business models.
Shareware is a type of proprietary software that is initially shared by the owner for trial use at little or no cost. Often the software has limited functionality or incomplete documentation until the user sends payment to the software developer. Shareware is often offered as a download from a website. Shareware differs from freeware, which is fully-featured software distributed at no cost to the user but without source code being made available; and free and open-source software, in which the source code is freely available for anyone to inspect and alter.
In software development, frontend refers to the presentation layer that users interact with, while backend involves the data management and processing behind the scenes. In the client–server model, the client is usually considered the frontend, handling user-facing tasks, and the server is the backend, managing data and logic. Some presentation tasks may also be performed by the server.

Filesystem in Userspace (FUSE) is a software interface for Unix and Unix-like computer operating systems that lets non-privileged users create their own file systems without editing kernel code.

The eDonkey Network is a decentralized, mostly server-based, peer-to-peer file sharing network created in 2000 by US developers Jed McCaleb and Sam Yagan that is best suited to share big files among users, and to provide long term availability of files. Like most sharing networks, it is decentralized, as there is no central hub for the network; also, files are not stored on a central server but are exchanged directly between users based on the peer-to-peer principle.
ProTERM is a terminal emulator and modem program for the Apple II and Macintosh lines of personal computers, published by Intrec Software.

SCO Skunkware, often referred to as simply "Skunkware", is a collection of open-source software projects ported, compiled, and packaged for free redistribution on Santa Cruz Operation (SCO) operating environments. SCO Skunkware packaged components exist for SCO Xenix, SCO UNIX, OpenServer 5–6, UnixWare 2 and 7, Caldera OpenLinux, and Open UNIX 8. SCO Skunkware was an early pioneering effort to bring open source software into the realm of business computing and, as such, provided an important initial impetus to the acceptance and adoption of open source software in the small and medium-sized business market. An extensive SCO Skunkware download area has been maintained since 1993 and SCO Skunkware components were shipped with operating system distributions as far back as 1983, when Xenix for the IBM XT was released by The Santa Cruz Operation. The annual SCO Forum conference was a venue for the makers and users of SCO Skunkware to meet and discuss its contents and ideas for future additions.
