Computer Networks NETWORKING CONCEPTS Network A network is basically an interconnection of various points to make a connected system e.g Road‚ Telephone‚ Social Data Network A computer network therefore refers to an interconnection of computers and other peripherals by use of a communication link Peer to Peer Networks In a peer-to-peer network‚ all computers are considered equal; they all have the same abilities to use the resources available on the network. Peer-to-peer networks are designed

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

NETWORK Computer Network also called Network is a group of computers and other devices connected to each other to share resources electronically. Networks can be as small as two computers or many thousand computers that are connected to one another. These computers are usually connected to one another through wires‚ satellite‚ and modems. Each device connected to the network is called a “node”‚ and the computer that is connected to the network is called a workstation. There are several ways
