What Is a URL

URL stands for Uniform Resource Locator Sample: { < http://www.microsoft.com/ > }
It is a method of coding your Web files so that the Web browser like ( Google Chrome, Microsoft Internet Explorer,  Opera, Firefox, Microsoft Edge, Safari and other Browsers) can go and tell your Internet Providers Web server machine  how to access a particular type of Web Resource.

There are many types of Resources that the Internet offers. You can choose any or all of these when you make your Web pages.

In addition to Web Pages themself, other resources are available on the Internet through the Web are:
TELNET: allows you to connect to a remote computer a { host }elsewhere in the world.
Telnet is not automatically built into a Web Browser, it depends on an external program you may or may not have.
That host computer also must allow you to enter in as a Guest.
Common uses for Telnet are connecting to an information service, a commercial service provider, a BBS on the Internet, a public chat system, or low cost Internet Providers.

Most likely you will connect to your web space through ftp (File Transfer Protocol) which is the standard network protocol used for the transfer of computer files between a client and server on a computer network. Most Companies let you connect through what is called a cPanel where you can do all your uploading and changing everything that needs changing.

To get a program to ftp go to Coffee Cup FREE FTP4.5, Coffee Cup has more Free Programs and many programs at affordable prices to make your Web Creations a Success!!!
If you have a lot of available money on hand you could also go to Adobe for the neat Dreamweaver program, here is the link: http://www.adobe.com/products/dreamweaver.html

Best if you make yourself a Folder open Notepad or Word and write all your Passwords and Login Names down that you have with your ISP’s and save into that Folder. This way you can access them in case you forget. I even go so far as putting them on a USB Flash Drive and if I need the info stick the USB drive in to access the info.
This way it is not in my computer should anyone hack into it.

If you've been surfing the World Wide Web, you have undoubtedly heard the term URL and used URLs to access various HTML pages from the Web. So, what exactly is a URL? Well, the following is a fairly simple, but formal definition of URL:
Definition: URL is an acronym that stands for Uniform Resource Locator and is a reference (an address) to a resource on the Internet.
It's often easiest (though not entirely accurate) to think of a URL as the name of a file on the network because most URLs refer to a file on some machine on the network. However, you should remember that URLs can point to other resources on the network such as database queries and command output.

The following is an example of a URL:

This particular URL addresses the Java Web site hosted by Sun Microsystems. The URL shown above, like all other URLs, has two main components separated by a colon (:): the protocol identifier the resource name
In the example, http is the protocol identifier and //renate-designs.us/ is the resource name.
The protocol identifier indicates the name of the protocol to be used to fetch the resource. The example uses the Hyper Text Transfer Protocol (HTTP), which is typically used to serve hypertext documents. HTTP is just one of many different protocols used to access different types of resources on the net. Other protocols include File Transfer Protocol (ftp), Gopher (gopher), File (file), and News (news).

The resource name is the complete address to the resource. The format of the resource name depends entirely on the protocol used, but for many formats the resource name contains one or more of the following components:
host name - the name of the machine the resource lives on
filename - the pathname to the file on the machine
port number - the port number to connect to (this is typically optional)
reference - a reference to a named anchor within a resource; usually identifies a specific location within a file (this is typically optional)
For many protocols, the host name and the filename are required and the port number and reference are optional. For example, the resource name for an HTTP URL must specify a server on the network (host name) and the path to the document on that machine (filename), and can also specify a port number and a reference. In the URL shown previously, java.sun.com is the hostname and the trailing slash '/' is short-hand for the file named /index.html.
When constructing any URL, put the protocol identifer first, followed by a colon (:), followed by the resource name, like this:
The java.net package contains a class named URL that Java programs use to represent a URL address. Your Java program can construct a URL object, open a connection to it, and read to and write from it. .
