Though weak, this paragraph is not a total washout. It starts with a topic sentence, and the sentences that follow are clearly related to the topic sentence. In the language of writing, the paragraph is unified (i.e., it contains no irrelevant details). However, the paragraph is not coherent. The sentences are disconnected from each other, making it difficult for the reader to follow the writer's train of thought. Below is the same paragraph revised for coherence.
A URL technically has five parts: the protocol, the domain name, the path, the directory and the file name. Consider the URL http://coolexample.com/funky/music.html. The protocol is http://, the domain name is coolexample.com, the path is /funky/music.html, the directory is /funky/ and the file name is /music.html.
A URL (Uniform Resource Locator, previously Universal Resource Locator) - usually pronounced by sounding out each letter but, in some quarters, pronounced Earl - is the unique address for a file that is accessible on the Internet.he URL contains the name of the protocol to be used to access the file resource, a domain name that identifies a specific computer on the Internet, and a pathname, a hierarchical description that specifies the location of a file in that computer.
