A Wild card in MS-DOS is a character that can be used to filter the data that you are searching. Wild cards that MS-DOS uses are * and ?

This can be understood by the following example:

If you want to search all the files starting with the letter - a

enter the following command in he command line

dir a*.*

Of if you want to search all the text files that will start with 'amin', you can use:

dir amin*.txt

Now, if you want all the files that begin with any letter and ends with 'amin.txt'

you can use:

dir ?amin.txt

which will show you:

aamin.txt

bamin.txt

camin.txt

This can be understood completely if you try it out yourself

Thank you

Single buffering is the simplest type of buffering. The web definition is that single buffers are OpenGL contexts that do not have back color buffers.

If you mean storage, you can find it with DIR

yeah
