QBASIC is a very simple, quick, and, easy to learn programming language; this makes it frequently a 'favourite' amongst, especially, people who are 'beginning' programmers.
Learning QBASIC introduces you to all of the necessary programming fundamentals; including, such things as...
literals(string/numerical)
variables(single/or, multiple: array variables/multi-dimensional array variables; different variable types(string/integer/single precision/double precision); variable scope: local/global/parameter passing)
modular code(functions/sub-routines/too, calling code stored in seperate files)
loops(for/next-enumeration loop, do/while-entry contorolled loop, do/until-exit controlled loop)
decision(if-then-else-end if/switch-case)
operators(comparison: <,>,<=,>=,<>,=; logical: NOT/OR/AND; mathematical: +,-,*,/,^)
graphics(pset/line/circle)
sounds(play: ABCDEFG)
-etc.
As well as, it's capable of producing many different kinds of program...

I'm NOT saying here that QBASIC is the 'best' programming language to go and learn; as the truth is there are far more highly advanced programming languages out there such as those that use OOP-Object Oriented Programming, for example, Visual BASIC; however, once you've already gone and learned how to use QBASIC, first; then, you should find it relatively straight forwards, and, easy to go and learn almost ANY other programming language; whether it's a BASIC related programming language or not.
NOTE: QBASIC descends from the BASIC family of programming languages.
I myself did learn, QBASIC, first; then, later, went on to study learning Visual BASIC/VBScript/ASP/HTML/CSS/Javascript/Java/XML/PHP/Pascal/Ruby/LOGO/-etc.; and, this is all thanks to my having gone and learned QBASIC to begin with; which, then, gave me a 'taste' for acquiring multiple different programming languages.

Qbasic and Quickbasic are not the same! Qbasic was a free interpreter that Microsoft included with MS-DOS. Although Quickbasic uses similar syntax as quickbasic it allows programs to be compiled.

The advantage of qbasic is that it is easy to learn, to start out,then one can move on to more complex, or advanced languages.
Statement numbers were a feature of BASIC, and while QBASIC supports them, they are by no means necessary.
the two types of data used in Qbasic is numeric data and alpha numeric data.
The default screen mode for Qbasic is 0.
In order to Download Qbasic you may do one, both or none of these two things: 1.) Go to "http://www.softpedia.com/get/Programming/Coding-languages-Compilers/Qbasic.shtml" and click download or 2.) use "Google.com" with the keywords Qbasic free download to find another website with a free qbasic downlaod.
