【MS-DOS ≠CP/M】一篇基礎文章【定義】

MS-DOS ≠CP/M

There were many similarities between CP/M and MS-DOS. Inspired by the 8-bit CP/M, Paterson’s 16-bit operating system used similar commands and some of the same programming interfaces, but it was a different internal implementation and used different file storage formats.

At Digital Research, Gary Kildall’s opinion was that MS-DOS infringed on their copyrights for CP/M. He was furious, and confronted both Bill Gates at Microsoft and IBM, but his lawyer recommended against a lawsuit.  ”Rather than sue, Kildall agreed to license CP/M to Big Blue. But he was astounded that when the PC was released, IBM charged $240 per copy for CP/M, and only $40 for DOS.” [3] Needless to say, the Microsoft offering became the dominant operating system for the IBM PC.

Paterson denied any wrongdoing. “I told him [Kildall] I didn’t copy anything. I just took his printed documentation and did something that did the same thing.” [5]

Thirty years later, Bob Zeidman, a programmer and expert in software intellectual property cases, conducted a detailed forensic examination of the code of QDOS, CP/M and PC-DOS. His conclusion? “QDOS was absolutely not copied from CP/M, and MS-DOS showed no signs of copying either. Kildall’s accusations about Bill Gates were totally groundless.” [4]

看完之後?他的差異,在於哪裡,他在說明【架構】並分解,兩種平台的相似。

我承認.....從西元2000年後,就沒有在「Grey Hat」過了?

況且,我們沒去玩弄中華電信的小烏龜.....我是安分守己的宅男
當然?駭客技術,是一種私下傳授的「奧義」,並不適合廣為人們學習!
畢竟,這樣多學習資訊的人?都被隔離~又隔離~切割~又切割~之後?
沒幾個能夠將「資訊整體」一窺全豹,自然沒有人,在資訊能力上,具有健全的行為。
至此,不少人都只懂得一部分?甚至更慘,活在一般資訊下,難以突破!

Dark Man 對於擁有「技術、技能、軟體、硬體、平台」並不自大,而是更加的重視「自我約束、安全管理」,曾幾何時?那些對「職能素養」相當重視的人,都一一退出職場;留下的只是「自我膨脹、爭名奪利」的人。

重視職能達成的人?會否越來越不容易工作;除了要應付工作之餘?

還要去面對「自我膨脹、爭名奪利」之輩.......這是「極其惡意」的事情,為何?仍要這樣去組織「職場環境」,就因為「權大通天、利大遮事」嗎?

這裡講述到的「軟體平台」,沒有花一定的時間去熟悉,是不可能深入,也不可能順利操作,有興趣的人,要多花時間投入,才能夠掌握網路運用。
