All computers need some sort of(71)(OS). Tile majority of modem home computers use some form. of Microsofts OS. The original Microsoft OS was called DOS though most computers use Windows. Windows comes in various versions beginning with(72)x then 95, 98, ME and currently XP. A few computers use IBMs O/SApples Mac uses their own OS beginning with OS I though most modem Macs use version x or x. Apples latest version is OS 10.x. In the past large companies and institutions would have an OS design exclusively for them but as the Commercial OS become more sophisticated the benefits of this practice is becoming less apparent. Some computer professionals,(73)(ISP)and(74)computer users use an OS such as UNIX(or a variant such as Linux), Windows NT or 2000(Win2k)or one of the other network or(75)based OS.

It is frequently said that computers solve problems only because they are "programmed" to do so. They can only do what men have them do. One must remember that human beings also can only do what they are "programmed" to do. Our genes "program" us.
Our "program" is so much more enormously complex, though, that we might like to define "thinking" in terms of the creativity that goes into writing a great play or composing a great symphony, into developing a brilliant scientific theory or a profound moral judgment. In that sense, computers certainly can't think and neither can most humans.
Surely, though, if a computer can be made complex enough, it can be as creative as we. If it could be made as complete as a human brain, it could be the equivalent of a human brain and do whatever a human brain can do.
But how lung will it take to build a computer complex enough to duplicate(复制) the human brain？ Perhaps not as long as some think. Long before we approach a computer as complex as our brain, we will perhaps build a computer that is at least complex enough to design another computer more complex than itself. This more complex computer could design one still more complex and so on.
In other words, once we pass a certain critical point, the computers take over and there is a "complexity explosion". In a very short time thereafter, computers may exist that not only duplicate the human brain but far go beyond it.
What information about computers can we get from the passage？
A．They are simple and they operate mechanically.
B．They can solve all kinds of difficult problems.
C．Computers are so advanced that they will control human being someday in the future.
D．They are not as complicated as human brain.
