What
is the Internet or is it internet?
|
HTML???
HTML is Hyper Text Mark-up Language. Basically it is a bunch of codes
put in unison to create paragraphs, headings, incorporate pictures,
or create links. HTML can be tough if not learned right. It is important
to have an instructor help you; if you decide to have a homepage.
How
do I find what I want?
Well, to do that you need to go to a search engine. We have several
listed in our Favorites
Section
What
is this http:// stuff?
Each Internet site is located on a server. A server is basically a computer
hooked up to the Internet, or internet. This hook up can be by ethernet,
or by modem.
Ethernet: A group of computers connected to the Internet using an ISDN. A common name for ISDN is "very fast modem thingie" (please excuse the laymans term.). Sometimes it uses a T1 link. Which in all sense, is optical fiber. Optical fiber is very fast.
Modem: A device used to transmit and receive digital data over normally analog communications lines, usually as an audio signal on telephone circuits. A modem attached to a computer performs a DIGITAL-TO-ANALOG CONVERSION of data and transmits them to another modem which performs an analog-to-digital conversion that permits its attached computer to use the data. The rate of data transfer can be increased using data compression. Wireless modems send or receive data as a radio signal. A fax modem enables a computer to send and receive transmissions to and from a FACSIMILE MACHINE.
So,
what does all this mean?
Well, let me use this as an example: http://199.17.198.6/Creative_Web/indexits.html
Okay, now let's dissect this.
http:// is the start code.
199.17.198.6
is the server where the HTML is
placed
(for web pages on AOL's server is "www.aol.com"; for Webcrawler's
page, it is "www.webcrawler.com")
(Sometimes, there is no www, or .com, it us how the server is set up.)
Creative_Web
is the account name. Also, the folder
name on 199.17.198.6's server.
(a different example is http://www.corel.com/xara/index.html, this time
xara is the account, or document folder)
indexits.html
is the name of the html
It can also be a htm.
Most starting pages are index.html, but in this case, since index.html
is the main company, indexits was used.
Let's do another: http://www.microsoft.com/ie/author/logo/default.htm
http:// Usual starting
www.microsoft.com Microsofts server
ie In this case, it is in the folder Internet Explorer (ie)
author Inside the folder "ie" is the folder author.
logo Yet another folder inside ie/author.
default.htm This time they use default.htm as the start page. Basically ie/author/logo is a group of folders hooked together, all trying to get into one directory. An example, is trying to load a paper you typed. You first must start the computer (http://); then go into your writing tool: ie Microsoft Word (www.microsoft.com); then click on file (ie/author/logo); then open your document (default.htm).
Brief
History:
Well, it started out as a military funded project. They wanted to
get scientists connected so they could share research and results. Also,
it was used for military alertness. For example, if one military base
was attacked, the information and strategies used by the opposition
were transmitted to another base. How did it become public knowledge?
With the development of TCP/IP connection ("Transmission Control
Protocol/Internet Protocol" a fancy name for connecting a group
of computers together) schools adopted it as a simple means to communicate.
One school could find information in another schools library, or visa-versa.
Soon, college students learned the system well, and out came the development
of "chat". Chat is in every sense exactly what it says. It
is a way for a group of computer users to talk back and forth across
this Internet. Thus out-sprung the Internet.
So
what are the codes?
URL Uniform Resource Locator (a name for an Internet site) http Hypertext
Transfer Protocol (used to access a WWW document.) You will find this
code at the beginning of most URL ftp File Transfer Protocol (usually
a place to download "stuff", you can download items.) faq A faq is just
Frequently Asked Questions. ASCII American Standard Code for Information
Interchange (ASCII is used to send or receive text based information
across the Internet.) It is al so HTML. This remains hidden from the
user. (If you want to view it, in your browser, click on "view", and
"document source" or "source") DNS Domain Name System. (A computer does
this automatically; what your comput er does when it is on the Internet,
for example, when you send email, your computer looks up this DNS which
is kind of like a street address on the Internet. Then it sends your
mail message. You will find an error if a system has no DNS).
Internet
vs. internet
There is a big difference between the Internet and an internet. An internet
is made when two or more networks are hooked together and a certain
type of data is transferred.
Networks: in computing, two or more computers connected for the purposed of exchanging messages and sharing data and system resources. A LOCAL AREA NETWORK (LAN) connects personal computers and workstations (each called a node) over dedicated, private communications links. A wide area network (WAN) connects large numbers of nodes over long-distance communications links, such as common carrier telephone lines. An internet is a connection between networks. The Internet is a WAN that connects thousands of separate networks in the U.S., Canada, Europe, and Asia, providing global communication between nodes on government, educational, and industrial networks.
The Internet is a collection of all the networks. The Internet is not on one computer, but on the computers of the world, thus the World Wide Web. The government tries to control the Internet, but it is an impossible task. No one person, or Country owns the Internet; everyone who uses contributes to its development. (Please note, this is not an article protesting the government.) The World Wide Web can be graphical or textual. This process is made by using HTML.
