How does it work?
In brief, all computers connected to the internet create
a giant network. These computers communicate sort of like people do when they
ask a question or reply with an answer. The computer acts in one of two ways,
as a client, which ask for data or server that receives the request and
returns the data to the client. For example, when you go to purchase something
on Amazon.com, the computer or device you are using is the “client,” while the
Amazon network is the “server.”
What are Web browsers?
A Web browser is a software application used to find,
retrieve and display content from the World Wide Web. Images, Videos, Pictures,
Software programs and more can be found using a web browser. Going back to the
previous section, “How does it all work,” the web browser is the client that
contacts the web server and requests the information you requested. Then the
web server sends the requested information back to the web browser which
displays the results on the computer, usually in the order of most relevant to
your search.[1]
For example, if you were to search for Ferraris using Google, the first site
that is listed is http://www.ferrari.com/en_us/.
But as you scroll down, the more irrelevant the results become.
There are number of web browser available, the most
popular of which is Google. In fact, the word Google has become so popular, it
is now a verb. For example, if someone were to ask “How did you learn how to
sew?” A person can now reply “I googled
it,” and most people will know what that means. But Google is not the only web
browser, when it comes to web browsers there number to choose from, each one
offers some unique features. The following is a link to a video that describes
some of the more popular search engines, their differences and features.
Email
Electronic mail, or e-mail for short, is the transmission
of messages over communication networks. Most messages sent via e-mail are sent
in text format, meaning they are mostly composed of words and numbers, however
pictures and videos can be added to an e-mail. [3]
While most people may think social networking sites like Facebook are the most
popular way people communicate, e-mail is the main method for electronic
communication worldwide because it is fast and convenient. The other benefit of
email is that users don’t need to present or online when a message is sent. As with all forms of online communication,
nothing is 100% private. Companies and individuals, if motivated, can find out
the content of your email. So be careful when at work if you decide to say
something less than flattering about your boss.[4]
