Students and children are among the top users who surf the Internet for research. Today, it is almost required that students should use the Internet for research for the purpose of gathering resources. Teachers have started giving assignments that require research on the Internet. Almost every coming day, researches on medical issues become much easier to locate. Numerous web sites available on the net are offering loads of information for people to research diseases and talk to doctors online at sites such as, America’s Doctor. During 1998 over 20 million people reported going online to retrieve health information. Entertainment : Entertainment is another popular raison d'être why many people prefer to surf the Internet.

تقرير عن الانترنت بالانجليزي كامل و جاهز عن اضرار و فوائد الانترنت In the 1950s and early 1960s, before the widespread inter-networking that led to the Internet, most communication networks were limited in that they only allowed communications between the stations on the network. Some networks had gateways or bridges between them, but these bridges were often limited or built specifically for a single use. One prevalent computer networking method was based on the central mainframe method, simply allowing its terminals to be connected via long leased lines. This method was used in the 1950s by Project RAND to support researchers such as Herbert Simon, at Carnegie Mellon University in Pittsburgh, Pennsylvania, when collaborating across the continent with researchers in Sullivan, Illinois, on automated theorem proving and artificial intelligence. A fundamental pioneer in the call for a global network, J.C.R. Licklider, articulated the ideas in his January 1960 paper, Man-Computer Symbiosis. "A network of such [computers], connected to one another by wide-band communication lines [which provided] the functions of present-day libraries together with anticipated advances in information storage and retrieval and [other] symbiotic functions." —J.C.R. Licklider, [1] In August, 1962, Licklider and Welden Clark published the paper "On-Line Man Computer Communication", one of the first de******ions of a networked future. In October, 1962, Licklider was hired by Jack Ruina as Director of the newly established IPTO within DARPA, with a mandate to interconnect the United States Department of Defense's main computers at Cheyenne Mountain, the Pen***on, and SAC HQ. There he formed an informal group within DARPA to further computer research. He began by writing memos describing a distributed network to the IPTO staff, whom he called "Members and Affiliates of the Intergalactic Computer Network". As part of the information processing office's role, three network terminals had been installed: one for System Development Corporation in Santa Monica, one for Project Genie at the University of California, Berkeley and one for the Compatible Time-Sharing System project at the Massachusetts Institute of Technology (MIT). Licklider's identified need for inter-networking would be made obvious by the apparent waste of resources this caused. "For each of these three terminals, I had three different sets of user commands. So if I was talking online with someone at S.D.C. and I wanted to talk to someone I knew at Berkeley or M.I.T. about this, I had to get up from the S.D.C. terminal, go over and log into the other terminal and get in touch with them. [...] I said, it's obvious what to do (But I don't want to do it): If you have these three terminals, there ought to be one terminal that goes anywhere you want to go where you have interactive computing. That idea is the ARPAnet." —Robert W. Taylor, co-writer with Licklider of "The Computer as a Communications Device", in an interview with the New York Times, [2] Although he left the IPTO in 1964, five years before the ARPANET went live, it was his vision of universal networking that provided the impetus that led his successors such as Lawrence Roberts and Robert Taylor to further the ARPANET development. Licklider later returned to lead the IPTO in 1973 for two years.[3 ]
