Computer Languages

Just like us, the computer has its own language to communicate within itself to get something done. Natural languages, such as English, are ambiguous, fuzzily structured and have large (and changing) vocabularies. Computers have no common sense, so computer languages must be very precise - they have relatively few, exactly defined, rules for composition of programs, and strictly controlled vocabularies in which unknown words must be defined before they can be used. Sometimes we have to use assembly language (Low-Level Language, LLL) because there just isn't any other sensible way of telling the computer what it must do.
Through the ages there have been many languages for the computer. Different kinds of languages emphasize different things about the problem, and so are better at describing different aspects of the solution, or even different kinds of problems and solutions. Computer Science is ever-changing, so there is continual evolution of the concepts we need to use and the notations for describing these concepts. The earliest languages had few restrictions, so they were very powerful, but turned out to be very dangerous to use. After a while, people developed languages that were much safer to use, but there were complaints about their lack of power. Nowadays, we are starting to see languages that are both safe and powerful, but the process has a long way to go yet. The very earliest languages had to be based on something, and that was probably simple instructions give to humans without much vocabulary or common sense i.e. children. However, although this is intuitive for simple problems, it became clear that this did not scale well - i.e. it becomes disproportionately hard to use as problem size increases. A programming language's surface form is known as its syntax. Most programming languages are purely textual; they use sequences of text including words, numbers, and punctuation, much like written natural languages. Programming languages share properties with natural languages related to their purpose as vehicles for communication, having a syntactic form separate from its semantics, and showing language families of related languages branching one from another. Many programming languages have been designed from scratch, altered to meet new needs, and combined with other languages. Many have eventually fallen into disuse. Programs must balance speed, size, and simplicity on systems ranging from microcontrollers to supercomputers. Thousands of different programming languages have been created, mainly in the computing field. Programming languages differ from most other forms of human expression in that they require a greater degree of precision and completeness. There have been so many languages in the past that its hard to tell which was the best, but all in all they all helped in developing the language of today which is easier and much faster in terms of speed and processing. In saying that the computer is not as different as we think, its just like us, only stationary.
