2.1 Describe the Components of the Web
 Many people use the terms Internet and Web in
place of each other; but they are different.
 The Web is a way of accessing and sharing
information over the Internet by using Web
Browsers
2.1 Describe the Components of the Web
 Web Browser is a software program that enables you
to view and interact with various resources on the
web.

Internet Explorer, Mozilla Firefox, and Google Chrome are the
most common
 Web page – is a formatted text document that a web
browser can display
 Web Site – is one or more Web pages that reside on a
single server
2.2 Explain How Web Addresses Work
 Every Web site is stored on a computer that is part of
a vast network. When you access a Web site you are
really accessing the computer that it’s stored on!
 The computer, just like your home, has a unique
address that you access called IP Address
 Users, thankfully , don’t have to remember the
numbers instead we remember a Domain Name

Yahoo.com, Google.com, ESPN.com etc.
 A web site for a domain is accessed with the help of a
unique code, known as a URL (Uniform Resource
Locator)
2.2 Explain How Web Addresses Work
Element
Description
http://
Indicates the protocol to be used to
access a file.
www
Indicates that the Web site is on the
Web.
microsoft
Indicates the name of the domain.
.com
Indicates the type of domain.
/learning/default.asp
Indicates the path of the document.
2.2 Explain How Web Addresses Work
 A URL also includes a domain name suffix, ending,
that indicates the type of organization the web site
belongs too.






.com – commercial organization
.edu – educational institutions
.net – network-oriented organization
.org – nonprofit organization
.info – informative in nature
.museum – used by a museum

There are country-level domains that are specifically used by a country or an
independent territory. Some examples of country-level domains include .ke for
Kenya, .in for India, and .jp for Japan.
2.3 Explore Web Sites by using a browser
 Most new browsers allow for “Tab” browsing
 Allows the user to open tabs, instead of many different
windows
 Internet Basics Web Hunt!
2.4 Search for Reliable Information on the Web
 Boolean Logic is a method of describing things.
 By using the operators AND, OR, and NOT, it is possible to
describe a concept so that a computer can determine if
information in a database matches the concept you are
searching for.
 Since computers can only evaluate if the conditions you
describe are 'true' or 'false,' you need to understand how the
computer uses the operators to perform your search.

2.5 Explain How to Perform Transactions over the Web
 Online Transaction refers to a business transaction
that is made over electronic systems, such as the
Internet

Usually requires some personal information – Typically
provided when making a User Name and Password
 When making transactions be sure the site is
trustworthy and that the vendor is certified
 Sites like PayPal allow you to have a safety net in
cases of fraud
3.1 Explain How E-Mail Works
 Electronic Mail is similar to the traditional postal
service; however now we send messages through
Network Servers
 Like traditional mail, you can also send “packages”
that include video, audio, pictures, and other
attachments
 Two types of e-mail clients:


Local e-mail are installed on your computer and you use them
to save email messages
Web based is accessed by using a web browser to access your
e-mail (Yahoo, Gmail, Hotmail etc.)
3.1 Explain How E-mail Works
 An e-mail address has two parts separated by the @
symbol
Information
Description
someone
This is the name you use to create your e-mail
address. People recognize the e-mail address with the
help of the user name. When you open an account
with an e-mail service provider, you can specify your
user name. The user name that you specify should be
unique. The e-mail service provider checks if the user
name you provide already exists. If it exists, you need
to provide another user name.
@
The @ symbol separates the user name from the
remaining part of the e-mail address.
example.com
This represents the domain name of the mail server,
where all your e-mail messages are stored.
3.2 Write and Send E-Mail Messages

3.3 Manage E-Mail Messages
 Just like your (H: Drive) you may need to organize
your Inbox



Create folders for important messages you don’t want to delete
Be sure to read your e-mail daily, to avoid them building up
Create contacts for people who e-mail you regularly
3.4 Identify Correct E-Mail Etiquette
Category
Language
Cc and Bcc
Description

Tone. When you write an e-mail message, you should follow the
basic rules of courtesy to greet and acknowledge the recipients.
Do not use all uppercase characters in an e-mail message
because such text is considered rude and can be misinterpreted
as shouting. In addition, you must avoid using offensive and
inflammatory language.

Grammar and punctuation. Most e-mail programs provide a
grammar and spell-check feature that can find errors in your email messages. Missing punctuations can make your e-mail
message confusing. In addition, avoid overuse of punctuations,
such as exclamation points or ellipses, to emphasize your
thoughts.

Emoticons. An effective one-to-one conversation includes use of
visual cues, facial expressions, and body language. In e-mail
messages, you can use emoticons or smilies, which are a
collection of characters, to convey your emotions. However, use
emoticons sparingly in business communication.
You can use the Cc field in an e-mail message to mark people who you
want to keep informed. Use this field to include only those people who
you want to send a copy of your message.
The people whose addresses you add in the To and Cc fields cannot
view the addresses that are in the Bcc field. Therefore, the use of the
Bcc field is often discouraged.
3.4 Identify Correct E-Mail Etiquette

Attachment
Description
Each e-mail account has a certain storage limit. Sending e-mail
messages that have large documents, pictures, or other types of files as
attachments may completely fill the e-mail inboxes of the recipients. As
a result, the recipients may not receive any more e-mail messages. In
addition, recipients might have to spend a considerable amount of time
to open attachments of large sizes.
To avoid these problems, you can easily compress the attachments that
you send with the e-mail messages.
Message format
Salutation

Length of e-mail messages. The length of your personal e-mail
messages need not be limited. Professional e-mail messages
should be concise and clear. However, do not use abbreviations
or delete necessary details to reduce the length of your e-mail
messages.

Formatting attributes. Formatting messages with attractive colors
and fonts help you create an interesting and eye-catching e-mail
message. However, some e-mail programs might not support
certain formats. Sometimes, richly formatted messages appear as
unreadable characters, which can confuse and irritate people. A
simple solution is to use the default formatting that is available in
your e-mail program.
In personal e-mail messages, salutations do not need to be formal. You
can begin your message with salutations such as Dear or Dearest.
In business communication, ensure that you use appropriate salutations
for the recipients. Formal salutation is the safest to use in your e-mail
messages.

Signature
Description
A signature is a small section of text that appears at the end of the
message. This text contains your contact information. In a hand-written
mail, you can easily add your signature at the end of the document.
Similarly, an e-mail message should include a signature to identify the
sender.
In case of personal e-mail messages, the recipient generally knows the
sender, and therefore, a signature is not necessary. However,
professional communication must include clear and precise signatures.
You can include your address, phone numbers, and e-mail address in
your signature so that the recipients can contact you, whenever needed.
Avoid using fancy quotations and formatting in your signature.
Reply
When you receive any professional e-mail messages, ensure that you
reply to the e-mail messages promptly. Delay in replying creates an
impression that you are disorganized or that you are not interested in
the communication. Additionally, retaining part of the original message
in the reply helps set the context of your e-mail message.
When replying to an e-mail message, you do not need to reply to all the
people marked on the e-mail message unless required.
