Programming

Programming language is the language used in the computer to perform certain tasks. As well as the language used in human in general, programming languages many kinds. Programming languages can be categorized based on levels, such as low level language, the language level is, high level language.
low level language is very mechanical, and difficult to be understood by humans. This language using binary code, which can be understood by the computer hardware and have a very good ability in accessing hardware. One of the language entry in this category is the assembly
Middle level language is the language of the rules written language approach similar to the human language but have a high level of ability and speed the process of accessing hardware similar to the low level language. One of the languages that enter this category is C. High level language is a programming language that is more close to human language. Most high level language has syntax to use the English language. In creating a program, programmers use a very general language, high level, such as C, Pascal, Basic.
Computers are machines that can perform a basic command (instruction set). Computers can only be given command of basic commands such. The commands are more complicated should be translated into a series of basic commands that can be understood computer (the commands included in the instruction set computer) that can ultimately resolve the desired task, even with the run some basic operation, not a complicated operation.
Programming language is a language that can be translated into a collection of basic commands such. Translation done by a computer program called a compiler. Each programming language has its own compiler. For example, C + + compiler will not understand the program written with the Java language. The syntax of programming languages more easily understood by the people of the basic syntax. However, of course, the computer can only perform the basic commands. But the place where the important role of the compiler as a mediator between the programming language with the command base.
