for navigating, accessing, transferring, sharing and storing Web-based information across networks (e.g., the Internet, intranets)
C. Knows how to establish and access a folder/directory hierarchy for the management of a website and its related files.

Competency 003: AA. Demonstrates knowledge of mechanisms
for navigating, accessing, transferring, sharing and storing Web-based information across networks (e.g., the Internet, intranets)
InternetInternet: 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.

Intranetit 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

Navigating across NetworksNavigating 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.
HTML(HyperText Markup Language)
Filename extension .html, .htm
Internet media type text/html
Type code TEXT

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 PagesImportant 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 StoringHard 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 pageshttp://
websearch.about.com/od/web20/a/online-storage.htm
Mozy – up to 2GB free storageMediaFire – unlimited uploads
and downloads, up to 200MBPhotobucket – 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 controlsFirewalls 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.
VocabularyInternet – 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.
VocabularyBandwidth – is the speed of how information
is transferredTransfer 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.
