As previously illustrated, each time DOS executes a program, it first must load the program into memory, when you are executing multiple programs via Microsoft Windows, Windows will places as many of the programs into memory as possible.

• 正如前面所说,每当DOS执行一个程序，首先它必须把程序装入存储器，当你正在通过microsoft Windows执行多个程序时，Windows就将尽可能地把多个程序装入存储器。
