Competency 003: A
A. Demonstrates knowledge of mechanisms for
navigating, accessing, transferring, sharing and
storing Web-based information across networks
(e.g., the Internet, intranets)
Internet
Internet: By defintion
is “a global computer
network providing a
variety of information
and communicating
facilities, consisting of
interconnected networks
using standardized
protocals.”
It is referred to as the
World Wide Web.

visualized by the Opte Project.

Intranet
it is the “term for a collection
of private computer networks
within an organization.”
For the use of the employees
within the company or
district.
Used for access to email,
services provided by server.
Examples:
- www.donnaisd.net
- www.utb.edu
www.donnaisd.net
www.utb.edu
Navigating across Networks
Navigating across networks –
also referred to as “surfing the
web”.
Each web site contains
information on a certain topic,
but it also gives you access to
other web sites with additional
information.
One must be careful when
surfing the web, because you
could easily get off topic –
quick!
Important to pick a good search
engine.

Accessing Web-based information
across Networks
In order to access information
from the Web, you need to
have the HTML (Hypertext
Markup Language). This is
the “code” for the website. (i.e.
<html>) and a web browser.
The web browser will read the
html format and compose it to
an easy to read web page.
The web page is very
organized and well thought
out.

Transferring Web-based
information across Networks
How you are able to transfer
data across networks deals
with - Bandwidth vs. Transfer
Data
Bandwidth is basically the
speed of how information is
transferred across networks
Transferring Data is set up
by deciding how much data
will be allowed to transferred.
Both (Bandwidth and
Transfer of Data) is important
to keep in mind when trying
to meet the needs of the
website.
Transferring Web Pages
Important to Consider:
-Back up files
-After your web page is
set up, upload your files
-Will be set up with your
new domain
Windows Easy File
Transfer Manager (free)
Sharing and Storing
Hard drives, USB flash
drives
Computer crashes!!!
Information is lost!!! Run
out of room!!!
Store it on the web!
“Web-based storage services
let you back up your data,
store your files on a Web
server, or share them quickly
and simply with anyone, often
at no cost.”
Examples:
Pbworks.com
Free or at low cost web pages
http://websearch.about.com/od/web2
0/a/online-storage.htm
Mozy – up to 2GB free storage
MediaFire – unlimited uploads and
downloads, up to 200MB
Photobucket – photo and video
storage only, thousands of images
Establish/Access folder/directory
for Management of Website
Files for a website
are created to help
“organize” the
structure of a web
page.
Compared to writing
an essay.
Network Security and Access Issues
(Firewalls, password controls)
The Network Access
Control is defined to have
standards and restrict who
has access to the website.
A big part has to do to
prevent viruses, host
intrusion, or identifying the
vulnerabilities of a system.
Firewalls, password controls
Firewalls are designed to
block network transmitting
based on the websites policy
or rules. It will however, allow
certain networks to transmit
their information.
Without firewall, your data in
the system is unsafe and can
be accessed by anyone.
Password Controls is a way
to authenticate users to have
access to a system.
Creating “strong passwords”
reduces the threat of password
compromise and will ensure
user authentication.
Vocabulary
Internet – a global computer network providing a
variety of information and communicating facilities,
consisting of interconnected networks using
standardized protocols.
Protocol – rules determining the format and
transmission of data.
Intranet – a company network, such as donnaisd or
utb.edu
Navigating– being able to move around the website
“surfing the web”
Accessing– being able to locate the appropriate web
pages based on the URL
Transferring– using bandwidth and transfer data to
send your web pages to a new domain.
Vocabulary
Bandwidth – is the speed of how information is
transferred
Transfer Data – is how much data will be allowed to
transfer.
Sharing and storing – being able to create and store
your data/information on a website such as
pbworks.com
Firewalls – a computer system designed to block
unauthorized access while allow outward
communication based on the websites policy.
Password Control – to authenticate users who have
access to website and its content.
