what is meant by scripts ,I`ve heard several scripts such as java scripts ,VB scripts ? what is their usage?

Answer 1

.

Script is a also like a programming language. But the difference between a programming language and script is that programming languages are executed in the computer where they are present. But scripts are mainly used to execute over the internet or some remote computers.

For eg. if you are writing a program in C, you will execute that program in the same computer where is executable file is present. But scripts are used in web designing and network programming to be executed some where else than the local system.

Good one...
Well the usgaes are many..
like if u r filling an form and forget to fill up ur name or number and submit it to the system..rather than the form going to the server and then saying that number is missing ...scripts can do it right at the moment ..this is where most of the scripts work efficiently and have earned their name..

the above was a bit technical ..a simple answer would be to make the work of the appliation easy...

For more detailed explanation if you are atechnical mail me on

Answer 3

scripts are interpreted code that is commonly used to perform relatively simple tasks, such as user text validation. It is often used as the glue between components (which are often compiled code in some other language).

This isn't to say that they can't be used to perform more complex tasks, its just for complex items scripting is more difficult to maintain and understand (not to mention debug) than writting a component in another language.
