Name and describe the four functions or processes that all computers must do. A computer is a system that is made up of hardware, peripheral devices, and software. Together they enable the computer to carry out four primary functions that define a computer. A computer accepts input, processes data, stores data, and produces data. Accepts input allows the computer to be influenced by the user, allowing it to be extremely dynamic in capabilities. For example the keys to an electric piano, the user is able to give the computer input. The input is then processed through the software to enable you to hear the sound, notes and the volume of the keys that you press. The data produced through the computer is made to your liking, then can be recorded and saved for later and even copied and burned onto a CD. Name and describe the two major Types of Software. Another part that makes up a computer is the software. Computers normally have two different types of software, system software and application software. System software is the master control for processing information, and gives the user a foundation for running application software. Application software on the other hand is additional software that does not influence the running of the computer itself, but specifies how the computer processes and produces data.

Name and discuss the four functions of a “Search Engine”. Search engines are used by web search sites that allow you to find specific information on the web. The four functions of a Search Engine are: The Web Crawler, the Indexer, the Database and the Query Processor. By using a web crawler, the engine combs the web to find links that are most relevant to your search. The indexer then takes the information from the web crawler and organizes it into a list and stored database. Then the query processor takes your search description and uses it to find the most relevant answers to your search.
The web is a book of countless pages, Google indexes each page and saves a compressed copy on its servers. When a search query is entered is goes through its database of captured material and retrieves matches based on the search query. In addition, to matching the words it also uses other methods to improve the quality of the search results. One of these is page rank. Pages that have more links are ranked higher and assumed to be of greater relevance than those that are less linked. It also looks at link structure and link text to determine relevance of a page. These filtering mechanisms enable it to return search results of greater relevance and higher
The algorithms of search engines are as mysterious as the Force in Star Wars. Some claim to know everything there is and keeps up with the latest updates from Google and Bing, while others know the underhanded tactics that let them squeak by during the updates.
Basic Search TechniquesSince the Google web interface is so easy to use, I won't describe the basic functionality of the http://www.google.com/ web page. Instead, I'll focus on the various operators available:
In the development of web search Link analysis the analysis of hyperlinks and the graph structure of the Web have been helpful which is one of the factors considered by web search engines in computing a composite rank for a web page on any given user query. The directed graph configuration is known as web graph. There are several algorithms based on link analysis. The important algorithms are Hypertext Induced Topic Search (HITS), Page Rank, Weighted Page Rank, and Weighted Page Content Rank.

The term SEO refers to the process of affecting a website's visibility or ranking in search engine's natural or organic search results. Search engine optimization is one of the most powerful forms of online marketing.
Search engines have many capabilities from using key words or phrases to find what you are looking for to using general statements to browse the web. But what exactly is a search engine? Search engines are huge databases of web page files that have been assembled automatically by machine. There are two types of search engines. One type is the individual search engine. This type of search engine compiles its information on to its own database making it accessible when you use that particular engine. It does not use any other engine?s information to help with your search. Then there are the meta-searchers which do not have their own databases. They use a combination of individual search engine?s information simultaneously, from a single site and using the same interface. Meta-searchers provide a quick way of finding out which engines are retrieving the best results for you in your search. There are two ways that Meta-searchers show their results. Most use a single list which display multiple-engine search results in a single merged list and had removed all the duplicate entries from the list. The second way that they display their results is through multiple lists. These are separate lists in which are displayed as they are received from each engine leaving the duplicate entries on the list.
“A search engine is a tool that enables users to locate information on the World Wide Web. Search engines use key words or phrases entered by users to find Web sites which contain the information sought” (www.getnetwise.org/glossary.php). It can be considered a modernized library card catalogue. Search engines are the primary use for the internet. It's important to understand that search engines do not search the internet itself. They rely on spiders or robots to search databases of information through the internet which the company hosting the search engine has developed (http://www.cln.org/searching_faqs.html). The most popular search engines are Google, Yahoo, Excite, HotBot, AltaVista, Lycos and LookSmart.

Google is the favored search engine because of the fact that it is exceptionally user-friendly. In just a few letters typed into the search bar, Google can guess what you’re about to type and if you’re “feeling lucky” the site will bring you right to the information that you’re longing for. Google also has numerous add-ons such as Images, News, Maps, and Calendar, but a great deal of those add-ons are not only helpful and educational but interesting including, Google Wedding Planner, SkyMaps or Translate. Using Translate you can type any word in English, choose whatever language you’d like to transform it to and Google will do all the work by giving you the translation within seconds. These extras open a whole world that without Google would be much more difficult. All the add-ons that Google has developed to compliment their site, spark the imagination. It gives people ideas that range anywhere between learning a foreign language using Google Translate to learning about our solar system through Google
Computers are helpful because they offer a wide range of functions and services that are not available anywhere else. There are four main uses: word processing, internet/communications, digital video/audio composition, and desktop publishing.
