The most accurate and most boring way to (105) Java is that it is a new computer programming language developed by Sun Microsystems that creates (106) independent programs that can be distributed and nm remotely. To run Java programs, a computer must have a Java interpreter. Currently (107) Java programs are small "applets" that are (107) as part of web pages.
When you use a Java (108) browser to view a Web page that includes a Java applet, the browser loads the applet onto your computer through your modem or network. Then the Java interpreter runs the applet, which could include animation or sound, on your computer rather than transmitting the code bit by bit over Internet.

A.animation or sound

B.animation and sound

C.animation and be run

D.animation and be loaded
