Data Link Control (internet) :: essays research papers

Society has become based exclusively on the ability to move large comes of information across long distances quickly. The natural evolution of computers and this need for ultra-fast communications has caused a global mesh of interconnected computers to develop. This global network exclusivelyows a person to send netmail across the world in mere fractions of a second, and enables even the greenness person to access information world-wide. With the new advancements in technology at that place must be a set of rules or better cognise as protocols that must be established and utilized at all eons. In this short ten page paper I give be demonstrating the advancements in these protocols and there uses today.To properly show the significant advancement, it entrust be best to show why Data Link check over was established. In the early 1970s, the U.S. Defense Advanced Research Projects Agency (DARPA) started a research program interlinking computer to share information. While d irect information from one site to the other many problems arose with loosing information (Society). To drop-off the amount of corrupted data cosmos transmitted, protocols were established. These protocols were a drawn step to the fore process that was very slow but was able to transfer data all across the world. By 1986, the US National Science nates Started the NSFNET which today provides one of the biggest backbones for the mesh. This supercomputer was able to send packets on its 45 MBps proboscis to different locations. Once this was in place the internet was born with transmission control protocol/IP Protocols of TCP/IP protocol suite became available in the 1980s. . By 1991-93 Home computers were starting to take advantage of the vast amount of information that is available. By this time the OSI protocol was created and by the end of 1991 the internet has grown to include 5,000 networks in three countries, serving over 700,000 troops computers used by over 4,000,000 p eople. This was all possible due to strict sets of protocols that were followed (Society). By the mid to late 1990s society was using 56K modems in the residential areas and companies were purchasing faster dedicated connections. At this period of time flow control, error control, and High-level Data link Control (HDLC) were being implemented. The control of the data being processed is referred to as flow control. tend control was needed to be established to regulate the speed of data being transmitted. Regulating the speed of the transmission evens out the data so that very little errors will occur.
