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

QUESTION1 Power Problems Alternating current (AC)‚ which is “food” to PCs and other network devices‚ is normally 110 volts and changes polarity 60 times a second (or 60 Hertz). These values are referred to as line voltage. Any deviation from these values can create problems for a PC or other network device. Power problems fall into three categories: * Overage * Underage * Quality Power Overage Problems During a power overage‚ too much power is coming into the computer. Power overage

and pirating in the networks is very easy and it can lead to information damage or robbery and also if one compute is affected by a virus it can spread to the other easily. 3. What technology allows computer networks without wires? Wireless networking allows computer networks without wires. 4. Describe the difference between a LAN and a WAN. LAN is local area network‚ it consists of a group of networked computers that all located in one building. But WLAN is wide area network‚ it is a group of

communicate successfully. IEEE 802.11 is a set of standards for implementing wireless local area network (WLAN) computer communication in the 2.4‚ 3.6‚ 5 and 60 GHz frequency bands. They are created and maintained by the IEEE LAN/MAN Standards Committee (IEEE 802). The base version of the standard was released in 1997 and has had subsequent amendments. These standards provide the basis for wireless network products using the Wi-Fi brand. The most prevalent is 802.11b. Equipment using

Network security Security has moved to the forefront of network management and implementation. The overall security challenge is to find a balance between two important requirements: the need to open networks to support evolving business opportunities‚ and the need to protect private‚ personal‚ and strategic business information. The application of an effective security policy is the most important step that an organization can take to protect its network. It provides guidelines about the activities
