a stupid DOS question

Post  Nishchal on Tue Jun 01, 2010 6:38 pm

Yes it is a stupid but fairly simple question about DOS.

Q:- why do we have to have two different type of DOS commands?. (i.e Internal and external).

i think the designer of dos ie bill gates divided commands in two types to served a purpose..
internal commands r used for doing simple tasks and external commands used to do complex task.
so if u r a general user....general user in the sense that you used dos only for doing simple task such as create directory,make a file ,type a file etc,then it is not complusory that u should know both types of commands.u can be a excellent general user by only knowing internal commands.but for a technical user,he should aware of both type of commands,and he should know that how these commands are to be used.

this is my view

sir, tell the exact reason......

haha nice try... but ur far from it

when the first DOS was released. it was so small that it could fit on to a disk (that time floppy).. so it was called DOS (disk operating systme)... but as its developer added more functionality to it. its size grown out of the "disk". so developer decided to remove certain non basic commands and placed it on to other "disks". and called them external commands.

that was how DOS remained on the one "disk".. and if someone wanted more functionality .. can just get 2nd disk and add the external commands to it.
