Answer 4

1. 001100- Assembly language began with replacing 0’s and 1’s with words.
2. Operating Systems were little more than a collection of these “words”. A bundle of application codes shared with multiple applications and put into a central repository and used over and over by different applications to accomplish similar tasks. Ex. sizing a window or calling a file.
3. Two schools of thought in the programming world A. pragmatic–just write the code to get things done that I need done (Visual Basic–Object Oriented). B. Code it for speed and flexibility–dominated Microsoft’s culture–and primarily used C and C++) Both schools code sat upon the Windows API (Application Program Interface) and used the core functions of the OS.
4. Next CLR.net Common Language Runtime sits between the OS and the dominate Microsoft Languages…namely VB.NET and C#
