OCaml is an acronym for Objective Categorical Abstract Machine Language, the name of the full-blown interpretation module of the core Caml computer programming language. It works on multiple platforms, processors, and operating systems as an open-source, freely licensed alternative programming alternative. This language is particularly associated with Unix® systems, which are seamlessly compatible with OCaml. The language is so adaptable that program components designed in OCaml can, in some cases, be integrated into components designed in C languages, and vice versa.

Programming machine languages, such as OCaml, Java®, and C are used to communicate directly with computer hardware during software development. Programmers use them to access the capabilities of hardware components, and to instruct programs how to execute particular functions. Open source programs can include programming tools as well as developed software; they are programs not associated with a commercial software company. They are offered directly to consumers by program development teams, generally for free.

At the beginning of a software design project, programmers choose appropriate languages by looking for features that will help them develop the functions they have in mind. OCaml's bytecode is generally attractive to programmers. Sometimes called a portability code, these numeric codes have the effect of making software more efficient. A flexible bytecode also allow software to be executed on computers made by different manufacturers or running different operating systems. OCaml’s bytecode is designed to provide processing speed, which is useful when programs require functions such as searches through large databases.

To ensure the successful functioning of any software program, programming languages must minimize glitches that might prevent them from returning the results that users are hoping for. OCaml is designed to handle "exceptions," or unexpected values or entries, by allowing programmers to code predictable and reliable responses to them. Software designers can build exceptions into their programs, so that those programs can recognize and react to them when they arise.

Sometimes, software can even cause errors that disrupt the functioning of users' computers. When this happens, it can cause other programs to fail, and can even harm computer files or operating system entries. OCaml, however, is specifically designed as a "safe" programming language, which limits the occurrence of these errors. Its efficiency, reliability, and safety — combined with its open source nature — combine to make it a useful option for programmers.
