A web browser acts on behalf of a user by:
- contacting a web
server
- requesting information
- receiving information
- displaying the results on a screen
A browser is software that interprets hypertext
markup language (HTML) – the language used to code web
page content. HTML can display graphics and play sound, movies,
and other multimedia files. Hyperlinks - computer program
commands that point to other places inside a PC, or on a network -
connect to other web pages and to files that can be downloaded.

some of the similarities and differences between these two browsers:
[Place

examples of Internet
applications.]
Netscape 
- first popular browser
- takes less disk space
- considered by many to be simple to use
- displays HTML files, does e-mail and file transfers, and
other functions
Internet Explorer (IE) 
- powerfully connected to other Microsoft products
- takes more disk space
- considered more difficult to use
- displays HTML files, does e-mail and file transfers, and
other functions
Plug-ins 
There are also many special, or proprietary, file types that
standard web browsers are not able to display. To view these
files you must configure your browser to use plug-in
applications. These applications work in conjunction with the browser
to launch the program required to view the special files.
- plays multimedia files; created by Macromedia
Flash
Example: Installing the Flash Plug-in.
- Go to the Macromedia
web site.
- Download .exe file. (flash32.exe)

- Test whether you can run a quiz and a movie.
Beyond getting your computer configured to view the web-based
curriculum, you can use computers to perform many other useful tasks.
In business, employees regularly use a set of applications that come
in the form of an office suite, such as Microsoft Office. The office
applications typically include spreadsheet software, a word
processor, database management software, presentation software, and a
personal information manager including an email utility. Spreadsheet
software contains tables consisting of columns and rows and is often
used with formulas to process and analyze data. A word processor is an application used to create and edit text documents. Modern word processors allow the user to create sophisticated documents, which include graphics and richly formatted text.
Database software is used
to store, maintain, organize, sort, and filter records – a record is
a collection of information identified by some common theme, such as
customer name. Presentation software is used to design and develop
presentations to deliver at meetings, classes, or sales presentations.
Personal information managers include such things as email, contact
lists, a calendar, and a to do list. Office applications are now as
much a part of everyday work today as typewriters were before the
personal computer.
