A path and a URL address two types related to computer science. An address is an identifier of a place. In a way, that location is somewhere in the directory structure of a computer. A URL is a Uniform Resource Locator. This is an address that points to a file that can be accessed via the Internet.
The first part of a URL is the scheme. For most Web pages, the plan is "http://" which tells the browser to use the hypertext transfer protocol (HTTP). The next element is the domain name that looks like "www.name.xxx." This is a reference to a web site address.
URL Structure
The rest of the URL is optional. If there is more text in the URL, which means that the file is searched is "index.htm" in the root directory of the site. If the file is in the root directory, but has a different name, the name of the file containing the Web page comes after the domain name. A URL can include a path: If the desired file in a directory other than the root, then the directory path preceding the file name. Some files require parameters, and these are the file name. You can also open a file and scroll down to a lower place on the page, in which case the location is the file name in the URL.
Road
A path is part of the URL structure, which shows the directory that contains a Web page you want. It can also be a reference to a location on a computer without using a URL. Despite a path leads through a directory structure for a file name, this is not your only goal. A directory run by a road can be a destination in itself, as part of a command to change directory or create a directory.
Notation
URLs are consistent in their notation. The division between the directories and file names is always marked by a slash ("/"). Routes using a notation that is issued by the operating system. For example, directories and file names are separated by a slash on Unix systems, but with a backslash ("\") on the PC. A reference to a route on a PC does not work in a Unix operating system, although the same directory structure that exists in both environments, because "the \ filename.ext" is not a recognizable way Unix. A URL always finds a file, starting from a universal point outside the current computer, even if it is pointing to a file on your computer.
Absolute and relative
URLs are always the absolute addresses. Specifying the location of the point of view of an unknown and distant place. A path can be used as part of an absolute address. For example, "C: \ first_dir \ sub_dir \ AFile.txt" is an absolute address beginning from the most neutral on the computer - not the current location. Roads can also be expressed as relative addresses. All operating systems recognize ".." as the "father" of the directory, so that ".. \ Sub_dir \ AFile.txt "leads to another subdirectory AFile.txt first_dir. In addition, a user or a program that operates in the directory can be referenced first_dir AFile.txt by sub_dir \ AFile.txt.
