6.4-6. Self Learning Switches (c). Consider the network below with six nodes, star-connected into an Ethernet switch. Suppose that A sends a frame to A', A’ replies to A, then B sends a message to B’ and B’ replies to B, and then A sends to B and B replies to A. In this sequence of frame transmissions, how many frames have appeared at the interface at C'? Assume that the switch's table is initially empty. [Note: You can find more examples of problems similar to this here.]
Suppose that a disk drive has 5,000 cylinders, numbered 0 to 4,999. The drive is currently serving a request at cylinder 2,150, and the previous request was at cylinder 1,805.

The language for coding must be in python Neural Network Units Implement a single sigmoid neural network unit with weights of [-1.2, -1.1, 3.3, -2.1] Calculate the outputs for two training examples:Example 1: [0.9, 10.0, 3.1, 1]Example 2: [0.9, 2.1, 3.7, 1] Note that you don't have to explicitly include a threshold or bias since the examples include a last element of 1 which means that the last weight effectively operates as a threshold. Assuming that a sigmoid unit response >0.5 denotes a positive class and <0.5 is negative class, is example 1 positive or negative? is example 2 positive or negative?

Define the neural network a fully connected network with two hidden layers with Nh1 and Nh2 features, respectively. The hidden layers should use relu activation and the final layer should not have any activation. a linear network with no hidden layer. We will use this network to study the benefit of depth, or equivalently using a non-linear network instead of a linear network. The final layer should not have any activation class NeuralNet(N.Module): # YOUR CODE HERE class LinearNet(N.Module): #YOUR CODE HERE
Consider the neural network shown below. The network consists of 2 input values (x1, x2) with their associated weights (0.3, 0.4, 0.3) and (0.2, 0.7, 0.1), 3 nodes in the hidden layer (h1, h2, h3) with associated weights (0.3, 0.5, 0.2) for target output. Assume all neurons have the same bias b = 0.2, and the same sigmoid activation function. If we input (x1, x2) = [1, 2], what will be the network’s output?

Q3) Consider weighted queueing scheme with three queues at the output port. The weights assigned to queues are w = 4, w = 2, and w = 1. The contents of each queue at time t1 are shown in below Figure. Assume packets are all the same size and that transmission time for each is 1 micro-second. Answer the following: c) Has queuing created jitter for each class?

Consider a system that handles railway connections as it associates (source) cities to all their corresponding destinations. The requirements of the system are as follows: 1. A source city may have connections to possibly multiple destination cities. 2. Multiple source cities may share the same group of destination cities. We introduce type CITY . A possible state of the system is shown below as it is captured by variable connections:connections ={Montreal → {Ottawa, Kingston, Quebec, Halifax},Ottawa → {Montreal, Toronto},Toronto → {Montreal, Ottawa},Halifax → {Montreal, Quebec},Quebec → {Montreal, Halifax},Kingston → {Montreal}} 1. Is connections a binary relation? Explain why, and if so express this formally. 2. In the expression connections ∈ (...), what would the RHS be? 3. Is connections a function?
