Chapter 7 Lab Exercise 7.1.1 Part of the distinction between LAN and WAN networks is ownership. Why is it impractical for an organization to own the entirety of a WAN? Why is it favorable for an organization to maintain ownership of the entirety of a LAN? Use your textbook and Internet research to compose your answer A) There are no limitations on WANs so they can be custom built for the size of the organization. For the purpose of organizational expansion. Exercise 7.1.2 Given the problems with

The steps 1 to 5 denotes the forward propagation 1. First apply the inputs to the network and work out the output. This initial output could be anything‚ as the initial weights are random numbers. 2. Next work out the error for neuron B. This error is needed actually ErrorB = OutputB (1-OutputB)(TargetB-OutputB) (5.19) Output (1- Output) is necessary in the equation because of the Sigmoid Function (Target – Output) is needed if threshold activation function is used. 3. Change the weight

network we can use a star topology and link all home computers to the ISP and router.Because we have proposed design in which there are two ISPs and routers we can use “Double-star Architecture” 5. In a lot of cases exactly one protocol data unit in layer N is encapsulated in a PDU at layer (N-1). It is also possible to break one N-level PDU into multiple (N-1)-level PDUs (segmentation) or to group multiple N-level PDUs into one (N-1)-level PDU (blocking). a. In the case of segmentation

1) Identify the three IP address classes‚ the default subnet mask used with each‚ and the number of hosts for each. The three IP address classes are class A‚ class B‚ and class C. Default subnet mask for class A = 255.0.0.0 Default subnet mask for class B = 255.255.0.0 Default subnet mask for class C = 255.255.255.0 The number of hosts that class A can have is 16‚777‚214 The number of hosts that class B can have is 65‚534 The number of hosts that class C can have is 254 2) What is the subnet

AODV has pooled properties of both DSR and DSDV. It uses route discovery process for sustaining route information through the basis of routing table. It is a reactive protocol as it doesn’t need to establish or maintain routes to nodes that are not involved in the communication. AODV handles route discovery process with Route Request (RREQ) messages to broadcast to neighbour nodes. The message floods through the network till the desired destination is reached. Sequence number guarantees the loop
