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. 
 
** They both are used to web pages look better and they both use tags and words to give the computer instructions. 

Discuss one difference between JavaScript and HTML that suggests only
JavaScript is a programming language.

**JavaScript is changing and html is constant.

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.

**A television's input can start either at the remote control by pressing the on button or by the on 
button on the tv itself. The output is the tv actually turning on and emitting sound. A portable CD player's
input is putting batteries in the back and the output comes from the ear phones where sound is heard.


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?

**Both
**Words were typed in notepad and saved, and then as an output, alert messages popped up when the browser was opened.
**Both
