Consider the Go-back N scheme with window size N = 2 and assume that 2 bits are used for the sequence number field. The sender has four packets (labeled A, B, C and D) to send to the receiver. Suppose that packet C is lost the first time that the sender tries to transmit it. Other than this event, all other packets are transmitted successfully over the channel. Draw two parallel timelines showing the sequence of events that at occur at the sender and receiver, respectively, beginning with the transmission of packet A and ending with the successful reception of packets A through D. Show the state of the sender's window (i.e., indicate ‘base' and ‘nextseqnum') after each event at the sender, assuming that initially
Assume that we try to predict this sequence with a BHT using one-bit counters. The counters in the BHT are initialized to the N state. Which of the branches in this sequence would be mis-predicted?
1. ) calculate the consumption of energy , taken from WAPDA, solar panels etc. 2. ) Transfer this data wirelessly to the grid station Please provide some ideas to implement this and list of components.
The circuit will have as inputs a minimum of two inputs; the binary equivalent of two decimal numbers of not greater than (10,000)10. The circuit will also produce a minimum of two outputs, the quotient and the remainder.
Compare GBN, SR, and TCP(no delayed ACK). Assume that the timeout values for all three protocols are sufficiently long such that 5 consecutive data segments and their corresponding ACKs can be received (if not lost in the channel)
Look up the Bell 103 modem and answer the following questions: (a) What year was the modem introduced(b) What baud rate did the modem operate at (c) What is baud rate How is it different than bit rate
Find the largest allowable signal swing (peak-to-peak) at the collector to satisfy the two conditions: BJT remains active , and vbe limited to 5 mV . What is the corresponding allowable peak-to-peak input voltage vi
(a) Determine the steady state error for a unit step input R(s) = 1 / s. (b) Assume that the complex poles dominate, and determine the overshoot and settling time to within 2% of the final value.
The voltage on bus 1 is 1.0 per unit (pu) at 30 degrees; the voltage on bus 2 is 0.95 per unit at 5 degrees. The reactance connecting bus 1 to bus 2 is 0.5 per unit Ohms, and the resistance is negligible. a)How much real power (pu) is flowing from ..
If I have a resistor that is 10 Ohms and has a voltage drop of 4.2 V, how much current is flowing through the resistor?
If the resistance path from the wall outlet end of the neutral wire to ground is 23ohm. what is the voltage of that point (relative to ground) if a 26 W compact fluorescent bulb is connected to the outlet
