Explanation / Answer
Part 2.
1. Browser plug-ins are compiled third-party software components that extend the functionality of web content by calling into low-level browser interfaces. In Internet Explorer, plug-ins take the form of ActiveX objects and Browser Helper Objects (BHOs). Two commonly used plug-ins on the web today are the Flash Player and Skype Click to Call, which on Internet Explorer install as a Microsoft ActiveX object and a Browser Helper Object (BHO), respectively. Other common browser plug-in technologies include Microsoft Silverlight, Apple QuickTime, and Java applets. Like Flash, these technologies provide an application framework and runtime for web developers to write plug-ins that extend the functionality of their sites and web applications.
Advantages:-
a. Consumers, with better performing browsing experiences, longer battery life on mobile devices, and increased security, privacy, and reliability
b. Web developers, with wider site interoperability across browsers and devices, better forward-compatibility, and overall easier site maintenance
c. The modern web, by promoting and populating a more open, accessible, and vendor-neutral web.
2. starting in about 1937 several groups around the world started constructing digital computers. World War II provided much of the motivation and funding to produce programmable calculating machines, for everything from calculating artillery firing tables to cracking the enemy's secret codes. The perfection and commercial production of vacuum tubes provided the fast switching mechanisms these computers needed to be useful. In 1945, Bush revisited his older ideas in an article entitled "As We May Think," which was published in the Atlantic Monthly, and it was this essay that inspired a young Douglas Englebart to try and actually build such a machine.
Douglas Englebart completed his degree in electrical engineering in 1948 and settled down in a nice job at the NACA Institute (the forerunner of NASA).
