History of programming compùtradora

To create a program, and the computer that interprets and executes instructions written on it, you must use a programming language.

In its early computersinstructions interpreted only in a specific language, the lowest level, known as machine code, and this is too complicated to program. In fact only consists of strings of 1's and 0 (binary).

Tofacilitate the programming work, the first scientists working in the area decided to replace the instructions, sequences of ones and zeros, by words or letters from the English, the coded and wellestablished high level language, known as Assembly or assembly language. For example, to add the letter A is used for the English word add (add). Actually writing assembly language is basically the same as itin machine language, but the letters and words are pretty easy to remember and understand that sequences of binary numbers.

As the complexity of the tasks performed computers increased, it becamenecessary to have an easy to program. Then, created high-level languages​​. While such a trivial task as multiplying two numbers may need a set of assembly language instructions in a high levellanguage simply just one.

Once you finish writing a program, either in assembler or a high-level language, you need to compile, ie translated into machine language.
In order to facilitate the work ofthe programmer arises the need for the computer understands a language other than their own, of ones and zeros, too complex for humans. It is necessary to reduce the distance between human languages​​and computer, so you create the Programming Languages​​. To approximate each other. With such languages ​​is not necessary to write "strings" of ones and zeros, it has an expressive medium with a higherlevel of abstraction that allow "tell" the machine what it is you have to "do" in a way closer to the human form.

So programming languages ​​are born of the type consisting assembler mnemonics...
