What's the difference between a programming language, a scripting language, and a markup language?

The primary difference between a "programming language" (C, C++, VB etc.) and a "scripting language" (PHP, ASP, JSP, JavaScript, VBScript)is that code written in a programming language needs to be compiled before it is run. Once it is compiled, it can be run any number of times.

Scripting languages, on the other hand, are interpreted at run-time. This means that every time you want to run the program, a separate program needs to read the code, interpret it, and then follow the instructions in the code. Compiled code has already been interpreted into machine language, so it is will typically execute faster because the conversion into machine language has already been done.

Markup languages (HTML, XML) are somewhat different from both of the others. A markup language is simply a set of tags that are used to "mark up" text documents so that sections of text can be logically arranged and labeled. These documents can be viewed as plain text, or, more commonly, are viewed through a browser. The browser parses the document, looking for markup tags, and it then arranges the text and/or formats it according to the values in the tags.

How To Learn English! ( గల గల ఇంగ్లిషు మాట్లాడటం ఎలా ? )
Here are some tips which may help you to master the English Language!
Speak without Fear
The biggest problem most people face in learning a new language is their own fear. They worry that they won’t say things correctly or that they will look stupid so they don’t talk at all. Don’t do this. The fastest way to learn anything is to do it – again and again until you get it right. Like anything, learning English requires practice. Don’t let a little fear stop you from getting what you want.

Use all of your Resources
Even if you study English at a language school it doesn’t mean you can’t learn outside of class. Using as many different sources, methods and tools as possible, will allow you to learn faster. There are many different ways you can improve your English, so don’t limit yourself to only one or two. The internet is a fantastic resource for virtually anything, but for the language learner it's perfect.

Surround Yourself with English
The absolute best way to learn English is to surround yourself with it. Take notes in English, put English books around your room, listen to English language radio broadcasts, watch English news, movies and television. Speak English with your friends whenever you can. The more English material that you have around you, the faster you will learn and the more likely it is that you will begin “thinking in English.” .

Listen to Native Speakers as Much as Possible
There are some good English teachers that have had to learn English as a second language before they could teach it. However, there are several reasons why many of the best schools prefer to hire native English speakers. One of the reasons is that native speakers have a natural flow to their speech that students of English should try to imitate. The closer ESL / EFL students can get to this rhythm or flow, the more convincing and comfortable they will become.

Watch English Films and Television
This is not only a fun way to learn but it is also very effective. By watching English films (especially those with English subtitles) you can expand your vocabulary and hear the flow of speech from the actors. If you listen to the news you can also hear different accents.

Listen to English Music
Music can be a very effective method of learning English. In fact, it is often used as a way of improving comprehension. The best way to learn though, is to get the lyrics (words) to the songs you are listening to and try to read them as the artist sings. There are several good internet sites where one can find the words for most songs. This way you can practice your listening and reading at the same time. And if you like to sing, fine.

Study As Often As Possible!
Only by studying things like grammar and vocabulary and doing exercises, can you really improve your knowledge of any language.

Do Exercises and Take Tests
Many people think that exercises and tests aren't much fun. However, by completing exercises and taking tests you can really improve your English. One of the best reasons for doing lots of exercises and tests is that they give you a benchmark to compare your future results with. Often, it is by comparing your score on a test you took yesterday with one you took a month or six months ago that you realize just how much you have learned. If you never test yourself, you will never know how much you are progressing. Start now by doing some of the many exercises and tests on this site, and return in a few days to see what you've learned. Keep doing this and you really will make some progress with English.

Record Yourself
Nobody likes to hear their own voice on tape but like tests, it is good to compare your tapes from time to time. You may be so impressed with the progress you are making that you may not mind the sound of your voice as much.

Listen to English
By this, we mean, speak on the phone or listen to radio broadcasts, audiobooks or CDs in English. This is different than watching the television or films because you can’t see the person that is speaking to you. Many learners of English say that speaking on the phone is one of the most difficult things that they do and the only way to improve is to practice.

Finally
Have fun
