A script is a jargon often used on informatics today. It’s a set of instructions that are executed by a computer. They act on many types of data and the pc returns the data as a value, like numbers, lists and others. The simplest scripts do nothing but return these values, by using the “return” keyword, which is usually followed by opened and closed parentheses. What appears between them is what will get returned. Almost all the scripts are used by non-technical people, because they turn working on a computer easier.

The scripts are frequently used to repetitive tasks performed repeatedly times automatically and to simplify complex ones. Some of them offer this possibility without the need for complicated programming languages. The scripts for Internet are, basically, a list of instructions which tells the server what to do to build up a requested web page. When a person runs it, the script will work and tell the server to follow instructions, like add a database record, create a HTML page, search or modify the database and others.   

Scripts are often used to provide the input that would, in the past, have to be typed in. For example, if an individual need to run a program several times, he can use a script to do it automatically, for as many times as he needs to run the file. The advantage of the scripts is that its computer code in their files can be directly executed to run a sequence of commands, as if it was a program, differently of the executable binaries, because the scripts don’t have to be compiled in order to be executed.

Many programmers increased the script languages and they became so sophisticated that they have been used to write elaborate programs. These ones, more often than not, still are called scripts, even if they go well beyond automating simple sequences of user tasks. The DHTML language, for example, is a script that creates effects for texts and objects. The C language also produces geometric forms. Many sites offer downloadable script items, which people can easily copy.
