Answer to Question 1

Information is classified into three types, based on how ordered and organized it is. Facts and data that are reasonably ordered, can be broken down into component parts, and organized into hierarchies are called structured information. For example, a credit card company maintains customer records in a structured format with elements such as last name, first name, street address, phone number, and email address.
Information that has no inherent structure or order is called unstructured information. For example, a manila folder in which educational certificates, employment records, bills, warranties, and medical prescriptions are stored.
The information category that falls between structured and unstructured information is called semi-structured information. It includes facts and data that show at least some structure, such as web pages and documents, which bear creation dates, titles, and authors.

Every flu season is different, and even healthy people can get extremely sick from the flu, as well as spread it to others. The flu season can begin as early as October and last as late as May. Every person over six months of age should get an annual flu vaccine. The vaccine cannot cause you to get influenza, but in some seasons, may not be completely able to prevent you from acquiring influenza due to changes in causative viruses. The viruses in the flu shot are killed—there is no way they can give you the flu. Minor side effects include soreness, redness, or swelling where the shot was given. It is possible to develop a slight fever, and body aches, but these are simply signs that the body is responding to the vaccine and making itself ready to fight off the influenza virus should you come in contact with it.
