Twitter allows you to reach out and stay connected with the people that matter most. Unlike store bought software that only changes when you upgrade it, Twitter can change almost overnight. When Twitter was launched in March 2006, it was promoted as a micro-blogging platform.

Twitter gives people the opportunity to exchange comments with other users all over the world. It has also become a reliable source for late-breaking news. Twitter offers a simple interface for sending and receiving messages. Simply enter your message up to 140 characters which is known as a tweet, and it will be instantly viewed by your followers.

A URI file stands for Uniform Resource Identifiers. This is a global identifier that can be accessed remotely. A URL is a form of URI. An URI doesn't necessarily refer to just a remote resource. It is also a compact string of characters that identify a resource in the internet, and enables interactions with different representations over a network using specific protocols. These are defined in schemes with specific syntax and associated protocols. It can be classified as both a URL and a URN. Both terms are complimentary.

Let's talk about how URI syntax works. There is a scheme name such as HTTP, followed by a colon then scheme specific part. The semantics of the part are determined by the specifications that govern each of the schemes. The URI forces the scheme to adhere to a generic syntax which reserves certain characters for special purposes without saying always what they are. It also forces restrictions to the scheme specific part to provide a degree of consistency when it has a hierarchical structure. Both URI and URL have a shared history. There have been many refinements over the years to each.
