Email
Email is essentially the simplest form of communication on the net, there are two main types, web mail, which you can use if you have signed up for an account with
Yahoo for example.
Yahoo will keep a list of all your contacts and messages for you to view anytime you need and on any computer you may be using. The other type of email is
POP3 which allows a user to download message onto their comnputer using an email client like
Outlook Express or
Mozilla Thunderbird.
URL
A Uniform Resource Locator (
URL) is a string of characters conforming to a standardized format, which refers to a resource on the Internet (such as a document or an image) by its location. For example, the URL of this page is
http://www.freesmileys.org/free-smileys-glossary.php.
An HTTP URL, commonly called a web address, is usually shown in the
address bar of
web browser.
Tim Berners-Lee created the
URL in 1991, to allow the publishing of hyperlinks on the World Wide Web (www), a fundamental innovation in the history of the Internet.
Address Bar
The
Address Bar is a part of your
web browser where you can type a url of the site you want to visit, many web browsers also have a Favourites drop down menu (
Internet Explorer) or Bookmarks (
FireFox) that allow you to bookmark or store favourite website locations in a single handy place that is easy to retrieve, instead of remembering every web address you go to.
Web Browsers
Web Browsers are client side software otherwise known as programs run on a persons computer, be it mac or pc that allow people to
browse websites on the internet.
Web browsers have now been installed on some phones (cell phones) allowing people to
browse certain websites on the internet via their mobile device.
There are many web browsers available for the pc, two very common ones are
FireFox and
Internet Explorer, which both also happen to be free to use.
Copy Pasting
Copy pasting is a great way of saving alot of time and finger power, if you want to share a
URL with a friend, insert a
smiley into an
email client or insert some story that you saw on an online newspaper to an
email to a friend then
copy paste is your friend. Basically you can
copy one set of text or image to what is called the
clipboard, and then
paste that information into another application, it's
VERY handy.
Here are the steps to
copy paste on a
pc:
- First, left click just in front of the text that you want to copy then drag the cursor over the text without letting go of the left button until you have highlighted all the text you want to copy.
- Then let go of the left mouse button and right click on the selected text, select copy from the menu that appears.
- Alternatively you can press the keys CTRL C at the same time.
-
- Or, if it is an image you want to copy to the clipboard, right click on the image then select copy.
- Goto the application you want to insert the image or text into, left click where you would like the information to appear, let go then either right click and select paste from the menu or press the keys CTRL V at the same time to paste it in.
Hotlinking
Every website on the net is stored on a computer somewhere and each website is like an island, for the most part, independent of other sites. Generally all the resources a website needs for itself is on a single
hosting account, it's own, and the settings of a website reflect this, allowing only itself to use it's own resources such as images and downloads.
But sometimes, it is neccessary or convenient to allow other websites to link to another websites resources. This is called
hotlinking. A website
hotlinking to another image (etc) does not use any of it's own
bandwidth limit, it's ability to
hotlink to another websites resource is only limited by the other websites
bandwidth limit. Needless to say if enough people
hotlink to a file, it has the ability to shut down a site to which the file being used is owned and is
hotlinked to.
Bandwidth
Bandwidth, though abundant it seems, is nonetheless limited on the net, almost all sites have a
bandwidth limit of some sort and when the
bandwidth limit is reached, the offending site is shut down by the
host or expensive charges are charged to the owner of the shut down site for the host to continue running it.
Bandwidth is basically the amount of
Data Transfer a site is allowed to use, once so much information has been downloaded by a websites visitors this
Data Transfer is used up and the site (normally) can no longer operate until it reaches a new month. Needless to say,
bandwidth costs $$$.
