do thus question for me

2. A client is trying to connect to a web server on an overloaded machine that only accepts an average of one in 10 connections. What is the probability the client gets a connection on the 4th attempt? Performance Measurements Definitions: Bandwidth(potential data rate), Transmission Rate(data rate), Transmission Delay, Propagation delay, Throughput, Latency. Packet Length: # of bits in a Packet Link Length: is the length of a link between the two ends of the link in meters. Data(bit) Rate: is the rate at which bits can be sent in bits per second bits/sec) Propagation delay: is the time it takes one bit to travel from one end of the link to the other. Propagation delay =d's where d is the distance and s is the speed(i.e., data travels with speeds on the link) Propagation time: Same as Propagation delay. Transmission Delay: is the time it takes to get all the bits of the packet onto the wire = packet_length/data_rate(rate of transmission)
