communications‚ switching communication network is a communication network which uses switching for connection of two non-adjacent nodes. Switching Communication Networks are divided into circuit switching networks‚ message switching networks‚ and packet switching networks. Communication is the most popular use of the Internet‚ with email topping the list of all the technologies used. Some of the types of communication technologies used also include email discussion groups‚ and chat groups. These

Chapter 4 Network Layer and Routing 1) What are the two main functions of a datagram-based network layer? What additional functions does a VC-based network layer have? 2) List and describe the ATM network service models. 3) Compare and contrast link-state and distance-vector routing algorithms. 4) Discuss how a hierarchical organization of the Internet has helped to scale to millions of users. 5) It is necessary that every autonomous system use the same intra autonomous routing algorithm? Why

CHAPTER 1 INTRIDUCTION TO WAN 1.1.1 Introducing Wide Area Networks (WANs) Which statement is true about the differences between a WAN and a LAN? ← WANs generally support higher bandwidth than LANs support. ← A WAN link typically traverses shorter geographic distances than a LAN link traverses. ← A WAN often relies on the services of carriers‚ such as telephone or cable companies‚ but a LAN does not. ← All WAN implementations generally use the same Layer 2 protocol but there

Frame Relay is a fast packet –switching protocol used for transmitting data packets in high-speed bursts across a digital network. It is based on the standards of previous switching protocols ISDN and X.25. (Micom‚ 2000) It provides a method for routing frames of information across a wide area network. The packet

Mandatory Detention of Child refugees in Australia The mandatory detention of children is one of the most cruel and inhumane rules of modern day Australia. It is unfair and cruel for the children that have to undergo through this kind of trauma as it mentally and physically affects them in a way that cannot be reversed. It handicaps them‚ and when they finally do get released‚ they will find that life is much harder for them. Mandatory detention is an acceptable and well established rule‚ but
