Microblogging
Microblogging is a broadcast medium in the form of blogging. A microblog differs from a traditional blog in that its content is typically smaller in both actual and aggregate file size. Microblogs "allow users to exchange small elements of content such as short sentences, individual images, or video links". These small messages are sometimes called microposts.
As with traditional blogging, microbloggers post about topics ranging from the simple, such as "what I'm doing right now," to the thematic, such as "sports cars." Commercial microblogs also exist, to promote websites, services and/or products, and to promote collaboration within an organization.
Some microblogging services offer features such as privacy settings, which allow users to control who can read their microblogs, or alternative ways of publishing entries besides the web-based interface. These may include text messaging, instant messaging, E-mail, digital audio or digital video.
Advantages
Twitter, Facebook, and other microblogging services are also becoming a platform for marketing and public relations, with a sharp growth in the number of social media marketers. The Sysomos study shows that this specific group of marketers on Twitter is much more active than general user population, with 15% following more than 2,000 people. This is in sharp contrast to only 0.29% of overall Twitter users who follow more than 2,000 people.Microblogging services have also emerged as an important source of real-time news updates for recent crisis situations, such as the Mumbai terror attacks or Iran protests. The short nature of updates allow users to post news items quickly, reaching its audience in seconds.

Basic Internet Terminologies
The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (often called TCP/IP, although not all applications use TCP) to serve billions of users worldwide.
A web browser is a Software application(computer software designed to help the user to perform specific tasks) for retrieving, presenting, and traversing information resources on the World Wide Web or it simply helps us to acess the internet (websites).
A web cache is a mechanism for the temporary storage (caching) of web documents, such as HTML pages and images, to reduce bandwidth usage, server load, and perceived lag. A web cache stores copies of documents passing through it.
Temporary Internet Files is a folder on Windows which holds browser cache ( is a temporary record of your internet activity, including images, sounds, and downloads, that is stored within a file on your computer for a short while)The directory is used by Internet Explorer and other web browsers to cache pages and other multimedia content, such as video and audio files, from websites visited by the user. This allows such websites to load more quickly the next time they are visited. C:\Documents and settings\LocalService\Temp\Temporary Internet Files\Content.IE5.
Each time a user visits a website using Microsoft Internet Explorer, files downloaded with each web page (including html,images etc are saved to the Temporary Internet Files folder, creating a cache of the web page on the local computer's hard disk, or other form of digital data storage. The next time the user visits the cached website, only changed content needs to be downloaded from the Internet; the unchanged data is available in the cache.
Despite the name 'temporary', the cache of a website remains stored on the hard disk until the user manually clears the cache.
The Temporary Internet Files cache can be useful in certain situations. For example, if no Internet connection is available, previously cached websites are still available offline.
A web page or webpage is a document or information resource that is suitable for the World Wide Web and can be accessed through a web browser and displayed on a monitor or mobile device. This information is usually in HTML or XHTML format, and may provide navigation to other web pages via hypertext links. Web pages may be retrieved from a local computer or from a remote web server. The web server may restrict access only to a private network, e.g. a corporate intranet, or it may publish pages on the World Wide Web. Web pages are requested and served from web servers using Hypertext Transfer Protocol (HTTP).
A web search engine is designed to search for information on the World Wide Web. The search results are generally presented in a line of results often referred to as search engine results pages (SERPs). The information may be a specialist in web pages, images, information and other types of files.

In computer networking and computer science, the words bandwidth, network bandwidth, data bandwidth are terms used to refer to various bit-rate measures, representing the available or consumed data communication resources expressed in bits/second or multiples of it (kilobits/s, megabits/s etc.).
