Introduction Information retrieval is a science related to documents and information searching. Information retrieval deals with the storage and representation of knowledge and the retrieval of information relevant to a specific user problem (Mandhl‚ 2007). Information retrieval technology mostly used in universities and public library to help students or information users to access to books‚ journals and other information resources that they needed. It also applies at organizations which having

File Storage and Retrieval Information stored in a mass storage system is conceptually grouped into large units called files. A typical file may consist of a complete text document‚ a photograph‚ a program‚ a music recording‚ or a collection of data about the employees in a company. Mass storage devices dictate that these files be stored and retrieved in smaller‚ multiple byte units. For example‚ a file stored on a magnetic disk must be manipulated by sectors‚ each of which is a fixed predetermined

search engines have become the most important way to information retrieval through the World Wide Web. Information has expanded greatly may consist of text‚ file‚ web page‚ image and other type. Images one important species in information retrieval‚ many users care about image retrieval from search engines where web image retrieval is a challenging task that requires efforts from image processing‚ link structure analysis‚ and web text retrieval.

multiple store theory of memory there are three different storage areas within the brain. Sensory memory is where the five senses are put to use and it has unlimited capacity like iconic and echoic storage and has different storage mechanism. However‚ the duration of sensory memory is very limited. Work bench memory is an area of the brain where information is stored for long-term memory and retrieval. In the same way‚ work bench memory has limited duration but

Encoding‚ Storage and Retrieval: The Processes of Memory Memory is very complex and a little mysterious. There is a lot to know about the way one can organize a lifetime of memories. Research has helped clarify several missing elements in the traditional three-stage memory model. One can now understand the way information is changed as it is encoded‚ stored and then later retrieved. These three processes can be described similarly to the memory of a computer. The first step to remembering a piece

recognition. The right hemisphere is indicated to be the part of the brain responsible for processing visual information in comparison to the left hemisphere which is more for language and analytical processing. Studies such as the preference test have reinforced this. Other studies on hemispheric preference include examining emotions‚ facial memory‚ facial features encouraging hemispherical preference and the impact of brain injury on hemispherical functioning. Hemispheric preference for facial recognition

Question 1 a) The difference between a subject directory and a search engine is the way in which the information about a website is gathered. Search engine is a program that finds Web sites‚ Web pages‚ images‚ videos‚ news‚ maps‚ and other information related to specific topic. A search engine is helpful in locating information for which we do not know an exact Web address or are not seeking a particular Web site. A subject directory classifies Web pages in an organized set of categories
