Fundamentals of Web Programming

Notes 2.3.2 Internet Explorer, Firefox and Safari

The two most popular browsers are Microsoft Internet Explorer and Firefox. Other major
browsers include Google Chrome, Apple Safari and Opera. While most commonly use to access
information on the web, a browser can also be used to access information hosted on Web servers
in private networks.

2.3.3 Web Browser History

In computing, the web browsing history refers to the list of web pages a user has visited
recently—and associated data such as page title and time of visit—which is recorded by web
browser software as standard for a certain period of time. Web browser software does this in
order to provide the user with a Back button and/or a History list, to go back to pages they have
visited previously, rather than relying on the user to remember where they have been on the
web.
In addition to the web browser software itself, third-party services can also record a user’s web
browsing history (completely or partially).

Example: In Google Web History, the clicks of registered users are recorded and stored
in individual user histories, each of which are browsable and searchable by that user (this is in
addition to the click-tracking Google records for its own internal purposes, such as advertising
click tracking). If the user installs the Google Toolbar, all pages that the user visits while logged
in to Google on that computer may be recorded as well.

!
Caution A potential benefit to the user is that they can review - and search through - all of
their web browsing history on any computer, but this can have privacy implications.

2.4 Html Tags

HTML tags (otherwise known as “HTML elements”), and their respective attributes are used to
create HTML documents so that you can view them in browsers and other user agents.

Notes Not all browsers/user agents support all HTML tags and their attributes, so you
should try to test your pages in as many browsers as you can.
