1. Question - 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.

One similarity between HTML and Javascript is that they are both used to enhance webpages by telling the computer
what to show when the HTML file is opened.  A difference is that Javascript usually requires an input from the user to
produce an output while HTML doesn’t do this.



2. Question - 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.

Input can be from the remote sending the information to change channels or volume of the tv. out put is on the screen and what you actually see and what you hear. input from a portable cd player could be the cd that is going to be played, or from you pushing buttons to skip to the next song. out put would be the music that you here and the number that it displays to tell you what song you are on.



3. Question - 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?

Yes the inputs would be entering the dollar amounts and the outputs would be the exchange rate.
