Post Lab 4.1

1. A programming language is designed to be a human-readable (and -writeable!)
way to tell computers what to do. Programming languages allow us to give
computers instructions. Most computer scientists would agree that JavaScript is a
programming language, but many would not consider HTML one. Discuss one
similarity between JavaScript and HTML that suggests both might be
programming languages.
Discuss one difference between JavaScript and HTML that suggests only
JavaScript is a programming language.
	- Because you write JavaScript programs inside your HTML web page files.


2. Consider the concepts of input and output in the context of everyday devices. The
telephone takes input via its dialing buttons (or dial, if you have a rotary phone)
and the end of the handset you speak into. Phone output comes from the ringer
and the end of the handset you listen to. Consider each the following everyday
devices and describe their input and output as thoroughly as possible: television,
portable CD player.
	-Radio, ibod, computer



3. Consider the short JavaScript program you work with in Parts 2 and 3 of this lab.
Does this program have input, output, both?
Describe the input and/or output.
How about the currency converter program? Does this program have input,
output, or both?
	-parts 2 and 3 had had bothinput and output 
	-the input is what your typing in and the output is what comes out on the page
	-it has both input and output
	-the input is the number your trying to convert 
	 and the output is the number your getting out
