Systems development methodology created to radically decrease the time needed to design and implement information systems. RAD relies on extensive user involvement, Joint Application Design sessions, prototyping, integrated CASE tools, and code generators.\n\n(or)\n\nPart of a methodology that specifies incremental development with constant feedback from the customers. The point is to keep projects focused on delivering value and to keep clear and open lines of communication. Oral and written communication is not completely adequate for specification of computer systems. RAD overcomes the limitations of language by minimizing the time between concept and implementation.

Define the possible scope of the public library system. A single library location that allows a registered library user (card holder) to browse through books, periodicals, and misc multimedia. It would be able rent out those items to the user as well as collect outstanding items from the user.\n\nSimple set of important features:\n\n1) Ability to sign up for a library card (register)\n2) Loan out a book\n3) Inventory a book\n4) Notify a user that a book is overdue.\n\nA more narrow scope based on the features above. (Level 1 decomposition)\n\nA library system would have a:\n\n1) Register a user subsystem - Collect User information from user, create an account, issue a card.\n\n2) Loan out a book subsystem - Determine if the book is in stock, determine if the book is on hold, determine if the book is meant to be checked out, set book/item to a "rented" status.\n\n3) Inventory a book subsystem - Get book from user, set book/items status to "available"\n\n4) Notify user book is overdue subsystem - Check if all books are accounted, issue overdue notice, look up users information, send notice to user.\n\nThe two techniques that can be employed in such a system is decomposition (breaking down a system into its smaller subsystems like we just did) and loose coupling (one subystem is not dependent on another one to function)\n\nTo get the idea of a multi-layer architecture, use the idea of decomposition. The further you break a system down into its parts, the deeper in the layers you go.\n\nCheck out articles on UML and decomposition. Together you should get an idea about this architecture.

Internet : \n\n                        The Internet is the worldwide, publicly accessible network of interconnected computer networks that transmit data by packet switching using the standard Internet Protocol (IP). It is a "network of networks" that consists of millions of smaller domestic, academic, business, and government networks, which together carry various information and services, such as electronic mail, online chat, file transfer, and the interlinked Web pages and other documents of the World Wide Web.\n\nContrary to some common usage, the Internet and the World Wide Web are not synonymous: the Internet is a collection of interconnected computer networks, linked by copper wires, fiber-optic cables, wireless connections, etc.; the Web is a collection of interconnected documents and other resources, linked by hyperlinks and URLs. The World Wide Web is accessible via the Internet, as are many other services including e-mail, file sharing, and others described below.\n\n\nCreation of the Internet :\n\nThe Internet is the worldwide, publicly accessible network of interconnected computer networks that transmit data by packet switching using the standard Internet Protocol (IP). It is a "network of networks" that consists of millions of smaller domestic, academic, business, and government networks, which together carry various information and services, such as electronic mail, online chat, file transfer, and the interlinked Web pages and other documents of the World Wide Web.\n\nThe USSR's launch of Sputnik spurred the United States to create the Advanced Research Projects Agency (ARPA, later known as the Defense Advanced Research Projects Agency, or DARPA) in February 1958 to regain a technological lead. ARPA created the Information Processing Technology Office (IPTO) to further the research of the Semi Automatic Ground Environment (SAGE) program, which had networked country-wide radar systems together for the first time. J. C. R. Licklider was selected to head the IPTO, and saw universal networking as a potential unifying human revolution.\n\nIn 1950, Licklider moved from the Psycho-Acoustic Laboratory at Harvard University to MIT where he served on a committee that established MIT Lincoln Laboratory. He worked on the SAGE project. In 1957 he became a Vice President at BBN, where he bought the first production PDP-1 computer and conducted the first public demonstration of time-sharing.\n\nLicklider recruited Lawrence Roberts to head a project to implement a network, and Roberts based the technology on the work of Paul Baran who had written an exhaustive study for the U.S. Air Force that recommended packet switching (as opposed to Circuit switching) to make a network highly robust and survivable. After much work, the first node went live at UCLA on October 29, 1969 on what would be called the ARPANET, one of the "eve" networks of today's Internet. Following on from this, the British Post Office, Western Union International and Tymnet collaborated to create the first international packet switched network, referred to as the International Packet Switched Service (IPSS), in 1978. This network grew from Europe and the US to cover Canada, Hong Kong and Australia by 1981.\n\nThe first TCP/IP wide area network was operational by 1 January 1983, when the United States' National Science Foundation (NSF) constructed a university network backbone that would later become the NSFNet. (This date is held by some to be technically that of the birth of the Internet.) It was then followed by the opening of the network to commercial interests in 1985. Important, separate networks that offered gateways into, then later merged with, the NSFNet include Usenet, Bitnet and the various commercial and educational X.25 Compuserve and JANET. Telenet (later called Sprintnet), was a large privately-funded national computer network with free dialup access in cities throughout the U.S. that had been in operation

Web 2.0 generally refers to a second generation of services available on the World Wide Web that let people collaborate, and share information online. In contrast to the first generation, Web 2.0 gives users an experience closer to desktop applications than the traditional static Web pages. The term was popularized by O'Reilly Media and MediaLive International as the name for a series of web development conferences that started in October 2004. Web 2.0 applications often use a combination of techniques devised in the late 1990s, including public web service APIs (dating from 1998), Ajax (1998), and web syndication (1997). They often allow for mass publishing (web-based social software). The term may include blogs and wikis. To some extent Web 2.0 is a buzzword, incorporating whatever is newly popular on the Web (such as tags and podcasts), and its meaning is still in flux.

In the true meaning, information technology is anything (from a paper form to a cell phone or computer) that allows people to organize and share information.\n\nIt is the media that we use to store and communicate ideas.\n\nIn the usual meaning, it refers to electronic devices that do the above.  In this instance the organization of information can be quite advanced and includes the ability to search and otherwise process information.\n\nThe detailed part of your question sounds like a homework question.  You should be able to imagine how writing implements first changed the world and how cell phones and computing is currently doing so.

nternet, the \n \nADVERTISEMENT\n \n Paper cups should be:  \n \n   \n Durable \n Cute \n Recyclable \n \n \n \n  \n \n \n \nInternet, the, international computer network linking together thousands of individual networks at military and government agencies, educational institutions, nonprofit organizations, industrial and financial corporations of all sizes, and commercial enterprises (called gateways or service providers) that enable individuals to access the network. The most popular features of the Internet include electronic mail (e-mail), discussion groups (called newsgroups or bulletin boards, where users can post messages and look for responses on a system called Usenet), on-line conversations (called chats), adventure and role-playing games, information retrieval, and electronic commerce (e-commerce).\n\nThe public information stored in the multitude of computer networks connected to the Internet forms a huge electronic library, but the enormous quantity of data and number of linked computer networks also make it difficult to find where the desired information resides and then to retrieve it. A number of progressively easier-to-use interfaces and tools have been developed to facilitate searching. Among these are search engines, such as Archie, Gopher, and WAIS (Wide Area Information Server), and a number of commercial indexes, such as Google or Yahoo, which are programs that use a proprietary algorithm or other means to search a large collection of documents for keywords and return a list of documents containing one or more of the keywords. Telnet is a program that allows users of one computer to connect with another, distant computer in a different network. The File Transfer Protocol (FTP) is used to transfer information between computers in different networks. The greatest impetus to the popularization of the Internet came with the introduction of the World Wide Web (WWW), a hypertext system that makes browsing the Internet both fast and intuitive. Most e-commerce occurs over the Web.\n\nEach computer that is directly connected to the Internet is uniquely identified by a 32-bit binary number called its IP address. This address is usually seen as a four-part decimal number, each part equating to 8 bits of the 32-bit address in the decimal range 0—255. Because an address of the form 4.33.222.111 could be difficult to remember, a system of Internet addresses, or domain names, was developed in the 1980s. Reading from left to right, the parts of a domain name go from specific to general. For example, www.irs.ustreas.gov is a World Wide Web site at the Internal Revenue Service, which is part of the U.S. Treasury Dept., which is a government agency. The rightmost part, or top-level domain (or suffix or zone), can be a two-letter abbreviation of the country in which the computer is in operation; more than 250 abbreviations, such as "ca" for Canada and "uk" for United Kingdom, have been assigned. Although such an abbreviation exists for the United States (us), it is more common for a site in the United States to use a specialized top-level domain such as edu (educational institution), gov (government), or mil (military) or one of the four domains designated for open registration worldwide, com (commercial), int (international), net (network), or org (organization). In 2000 seven additional top-level domains (aero, biz, coop, info, museum, name, and pro) were approved for worldwide use, and other domains have since been added. An Internet address is translated into an IP address by a domain-name server, a program running on an Internet-connected computer.\n\nThe Internet evolved from a secret feasibility study conceived by the U.S. Dept. of Defense in 1969 to test methods of enabling computer networks to survive military attacks, by means of the dynamic rerouting of messages. As the ARPAnet (Advanced Research Projects Agency network), it began by connecting three networks in California with one in Utah–

In a nutshell the internet is a massive network of computers with the main players having servers holding stored data. When you download a video from a website it is like retrieving a video from your cd or harddrive except you are downloading it from someone else's cd or harddrive on their server.\n\nSeveral factors keep "things online" online. The server computer holding stored data, telephone or cable companies, and associated electronic gadgets. The server computer needs to on and connected to the internet, the telephone lines need to be open or cable internet operating, and modems and nodes and all the other gadgets need to be in good working order.\n\nThat's it in a nutshell!

There really isn't any difference in describing what you need to a web developer or a software developer. They will both be looking for (if they are worth describing the problem to) in no particular order:\n1. context diagrams that define how the external interfaces interact with your system,\n2. what the requirements (functional, non-functional, constraints) of the system,\n3. a flow chart describing how the user interacts with your front-end,\n4. how you want the data to be stored,\n5. a set of well defined business rules have always helped me,\n6. describe what your vision of the application is, the goals and what you hope to accomplish in the future with it (this will help the developer make strong decisions may affect any future modifications and extensibility of the application).\n\nMy best recommendation to you is to just lay everything and anything you can think of down on the table. Obviously, do it after you've deemed them worthy of the job.

Management information system\n\n\nAs an area of study it is commonly referred to as information technology management. The study of information systems is usually a commerce and business administration discipline, and frequently involves software engineering, but also distinguishes itself by concentrating on the integration of computer systems with the aims of the organization. The area of study should not be confused with computer science which is more theoretical in nature and deals mainly with software creation, or computer engineering, which focuses more on the design of computer hardware.\n\nIn business, information systems support business processes and operations, decision-making, and competitive strategies.\n\nThe functional support role\nIt can also be called Data Base Management System wherein maximum utilization in an efficient manner based on the organisational needs is obtained by analyzing, processing and referenceing of Data Base. Not only for the business, but for all kinds of organisations such as Disaster Management Organisation for using it as Disaster Management Information System.\n\nBusiness processes and operations support function are the most basic. They involve collecting, recording, storing, and basic processing of data. Information systems support business processes and operations by:\n\nrecording and storing accounting records including sales data, purchase data, investment data, and payroll data. \nprocessing such records into financial statements such as income statements, balance sheets, ledgers, and management reports, etc. \nrecording and storing inventory data, work in process data, equipment repair and maintenance data, supply chain data, and other production/operations records \nprocessing these operations records into production schedules, production controllers, inventory systems, and production monitoring systems \nrecording and storing such human resource records as personnel data, salary data, and employment histories, \nprocessing these human resources records into employee expense reports, and performance based reports \nrecording and storing market data, customer profiles, customer purchase histories, marketing research data, advertising data, and other marketing records \nprocessing these marketing records into advertising elasticity reports, marketing plans, and sales activity reports \nrecording and storing business intelligence data, competitor analysis data, industry data, corporate objectives, and other strategic management records \nprocessing these strategic management records into industry trends reports, market share reports, mission statements, and portfolio models \nThe bottom line is that the information systems use all of the above to implement, control, and monitor plans, strategies, tactics, new products, new business models or new business ventures.\n\nThe decision support role\nThe business decision-making support function goes one step further. It becomes an integral part -- even a vital part -- of decision -making. It allows users to ask very powerful "What if…?" questions: What if we increase the price by 5%? What if we increase price by 10%? What if we decrease price by 5%? What if we increase price by 10% now, then decrease it by 5% in three months? It also allows users to deal with contingencies: If inflation increases by 5% (instead of 2% as we are assuming), then what do we do? What do we do if we are faced with a strike or a new competitive threat? An organization succeeds or fails based on the quality of its decisions. The enhanced ability to explore "what if" questions is central to analyzing the likely results of possible decisions and choosing those most likely to shape the future as desired. "Business decision-making support function" is a phrase likely to quicken the pulse of no one but an accountant, but, in fact, it is all about turning wonderful dreams into solid realities.\n\nTetova ...\n\nThe communication decisi
