Internetworking What Is an Internetwork? An internetwork is a collection of individual networks‚ connected by intermediate networking devices‚ that functions as a single large network. Internetworking refers to the industry‚ products‚ and procedures that meet the challenge of creating and administering internetworks. History of Internetworking The first networks were time-sharing networks that used mainframes and attached terminals. Such environments were implemented by both IBM’s Systems

4. The Medium Access Sub Layer Broadcast channels [or multi-access channels] are a category of networks and the key issue is how to determine who gets to use the channel when there is competition for it. The protocols which define these factors belong to a sub layer of data link layer called the MAC(medium access control)sub layer. ALOHA: Norman Abramson devised a new and elegant method to solve the channel allocation problem called the “ALOHA” system which used ground-based Radio broad

Computer Networks Does anyone really know what networking is? “In the world of computers‚ networking is the practice of linking two or more computing devices together for the purpose of sharing data” (Networking Fundamentals). Now this is a great explanation but does this really help us understand? Networking has grown over many years. Where did networking come from? Lets go back to the beginning and find out how far we have come. Network research can be traced back to around the 1960’s.

Abstract In telecommunication systems‚ a generic access network (GAN) is used by cellular device users to connect and interact with other types of communication devices. GAN protocols primarily evolved for wireless communication systems‚ allowing mobile phones to perform functions seamlessly between wireless local area networks (WLANs) and wide area networks (WANs) without interrupting the communication session. Modern GAN technology permits a subscriber to interact via voice‚ data‚ IP multimedia
