What Is Software?

While we can distinguish various nonfree distribution schemes in terms of how far they fall short of being free, we consider them all equally unethical. With these freedoms, the users control the program and what it does for them. When users don't control the program, we call it a “nonfree” or “proprietary” program. The nonfree program controls the users, and the developer controls the program; this makes the program an instrument of unjust power. The programs, routines, and symbolic languages that control the functioning of the hardware and direct its operation.

If a copyright-based license respects freedom in the ways described above, it is unlikely to have some other sort of problem that we never anticipated . However, some free software licenses are based on contracts, and contracts can impose a much larger range of possible restrictions. That means there are many possible ways such a license could be unacceptably restrictive and nonfree.

A computer needs software to make it useful just as words are needed to make a book meaningful. For example, there are games on Steam that go for less than $5 and advanced programs, such as Cinema 4D Studio, can cost more than $3,500. Not only is the program free, but the source code is also available to everyone.

Defective by Design is a grassroots campaign to eliminate Digital Restrictions Management in media and devices. The Free Software Foundation is a nonprofit with a worldwide mission to promote computer user freedom. Software is durable and doesn’t wear out, but with time, bugs may arise in the software which could be rectified. Software can be easily created, changed or deleted, whereas switching out hardware takes greater skill and is typically more expensive to do. After the software is installed on your computer, it may need to be updated to fix any found errors.

Programmers typically interpret instructions from software developers and engineers and use programming languages like C++ or Java to carry them out. Just as with the personal computer, mobile devices such as tablet computers and smartphones also have operating systems and application software. In fact, these mobile devices are in many ways just smaller versions of personal computers. A mobile app is a software application programmed to run specifically on a mobile device.

Programs written in 4GLs are generally far less efficient during program execution that programs in high-level languages. Therefore, their use is limited to projects that do not call for such efficiency. Query languages and report generators make it unnecessary to develop certain applications by providing direct access to a database. Application generators make it relatively easy to specify in nonprocedural terms a system for such access. Use nonprocedural languages that encourage users and programmers to specify the results they want, while the computers determines the sequence of instructions that will accomplish those results.
