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.

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.

The following table also has a "Program?" column to clarify any software that's not a program. Open-source software comes with a free software license, granting the recipient the rights to modify and redistribute the software. The software's license gives the user the right to use the software in the licensed environment, and in the case of free software licenses, also grants other rights such as the right to make copies. Sometimes it involves moving data between memory and registers which enable high-speed data access in the CPU. Moving data, especially large amounts of it, can be costly; this is sometimes avoided by using "pointers" to data instead. Computations include simple operations such as incrementing the value of a variable data element.

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.

In today’s environment, it is important to develop relationships with your customers, and the use of a well-designed CRM can allow a business to personalize its relationship with each of its customers. The initial wave of software-application development began in the 1960s, when applications were developed for mainframe computers. In those days, computing was expensive, so applications were designed to take as little space as possible. One shortcut that many programmers took was in the storage of dates, specifically the year. Instead of allocating four digits to hold the year, many programs allocated two digits, making the assumption that the first two digits were “19”.
