1. What is a web browser? How does it work?

>>A web browser is a software application for retrieving, presenting, and traversing information resources on the World Wide Web.

2. What is a bookmark?

>>A bookmark is a page keeper. A reader inserts a bookmark into the pages of a book when he or she stops reading. This way when it's time to read again, the reader can open the pages where the bookmark is to find the place in the book where he or she left off at rather than trying to remember the page number.

3. What is the purpose of a web [browser] cache?

>> A web cache is a mechanism for the temporary storage (caching) of web documents, such as HTML pages and images, to reduce bandwidth usage, server load, and perceived lag. A web cache stores copies of documents passing through it; subsequent requests may be satisfied from the cache if certain conditions are met.

4. What is a web [browser] plug-in?

>> In computing, a plug-in(or plug-in) is a set of software components that adds specific abilities to a larger software application. If supported, plug-ins enable customizing the functionality of an application. For example, plug-ins are commonly used in web browsers to play video, scan for viruses, and display new file types.

5. Choose three types of web browsers and answer the following questions for each browser.

• How do you set homepages?
• Click on your Internet Explorer icon; you'll find this in your Start menu, or the toolbar at the bottom of your desktop window. Type in "Google" to IE's search box at the top of the browser window (this is just an example, you can use any website that you want). Arrive at Google search engine home page. Go to toolbar at the top of browser, and click on "Tools", then "Internet Options". At the top of the pop-up, you'll see a "Home Page" box. The address of the site that you are currently at (http://www.google.com) is there. Press the "Use Current" button to specify this page as your home page.
•  
• How do you clear the cache?
• Although it's not required by all browsers, restarting your browser after clearing the cache is a good idea. If you're using Explorer 4.x or Explorer 5.x it's better to restart the computer as well.
•  
• How do you install a plug-in?

All you need to do is to copy (or drag) the file into the Plug-Ins sub-folder of the Photoshop folder. For example, for Photoshop CS3 it's typically located at:

Program Files\Adobe\Adobe Photoshop CS3\Plug-Ins (for Windows) or
Applications\Adobe Photoshop CS3\Plug-Ins (for Mac OS).
