What is the minimum you would recommend a beginning web developer to do before attempting to place a file “live” on the web?
One excellent “best practice” to follow when you begin your web development activities is to promise yourself that you will thoroughly test any of your web pages before “putting them up on the web” (or, “putting them online”). This involves testing pages “offline”. That, in turn, means testing them on your computer, or on a part of your website hosted by your ISP which is not directly (or obviously) accessible to the world at large. For simple static files this may require just displaying the file in your browser, but as you develop more complex pages other tests may be required. Another good habit to get into is the practice of viewing each one of your pages in more than one browser. In fact, the more browsers, the better. Not all browsers will display a given web page in the same way, and you need to know if there are any significant differences between those browsers that are likely to be used to view your site's pages.
These days many people use a computer running Linux to host their websites, and if they do, they would use the _______________ command to set the proper permissions on the files on their site.
-chmod
Explain the difference between a static web page and a dynamic web page.
A static web page is one that gets displayed and “just sits there”. No matter how many times you come back to that page, it always looks the same, and there is no interactivity on the page, such as buttons to press or forms to fill out. In the very beginning of the web, all pages were like this. The only form of activity one could perform on these pages was to click on a link and go to another such page. Of course, even that was a big event in the early days. Nowadays a great many web pages provide at least some interactivity with the user, and we refer to such pages as dynamic. A web page can be dynamic in different ways. It can provide a simple or complex form for the user to fill out, it can have buttons or images that change in some way when the mouse is over them, and it may even have content that differs each time you visit the page because that content comes from some source that is constantly being updated.

If someone asked you how to get started with web development, how would you answer them? Assume the questioner is already connected to the Internet, and give your answer in “generic” form, without assuming any particular computing platform, or mentioning any particular programs.
The first question that needs to be answered is whether the ISP the person is using permits users to set up their own websites. If so, then it will at least be possible to “get started” with web development. The basic tools needed for web development are very simple, and freely available by download from the Internet, though at least two of them are likely to be available “by default” on most any computer. The three tools you need are a text editor, a web browser, and a program for transferring files from your computer to your Internet Service Provider. The first two are almost certainly already on your computer, and you can find lots of options for the third by searching on Google for “file transfer program”. Once you have these three tools, you can create a simple file of text with a .txt extension, upload it to the place where your ISP has told you to place it, and then browse to the URL provided by your ISP to see your file to confirm that you are “up and running” on the World Wide Web.
If someone asked you what was involved in “getting an Internet connection”, how would you answer them? Assume the questioner is computer literate and owns a computer with a browser installed, but is just not “connected”.
The first thing to decide when thinking about “getting an Internet connection” is what you plan to use it for … just for browsing and perhaps sending e-mails, or for something more elaborate, like setting up a web site. Once you have made that decision, you need to look for an Internet Service Provider (ISP) who will provide all the things you have decided you need. That might include the ability to send and receive e-mails, some online storage capacity, and permission and the capability to set up your own website, to be “hosted” by your ISP. If the latter is your goal, you will have to give some further thought to how elaborate you want your website to be, and determine whether your chosen ISP can provide all the features that you want.
