In a CAN bus, there are three computers: Computer A, Computer B, and Computer C. The messages being sent are 1 millisecond long. Computer A starts sending a message on the bus; 500 microseconds later, Computer B starts to sends a message, and 500 microseconds after that, Computer C starts to send a message. When does Computer A retransmit its message?
Homework Answers
Solution:
The CAN bus are used for communication of computers without any host machine.
The CAN bus can transmit the data a machine at any particular time. It can transmit data from other machine along with the present data being transmission.
Data from A takes 500us to transmit then B transmit which take also 500us and at the end C transmits at a interval to 500us.
The total process takes T=1ms + 500us +500us =2ms time to complete the data transmitted form C.
Hence A can retransmit 1ms after the first transmission.

(TCO 4) The distance between two stations in a 10 Mbps LAN using CSM/CD multiple access method is 2,000 meters. Station A sends a long frame first and three micro seconds later, C starts sending a long frame. Notice that when C begins sending, the signal due to the frame from A has not reached station C yet. If it reached, station C would not send it. How many bits from station C have already been sent when it hears...

Helpp: Make an application Protocol Application log for text messages In this task, an application protocol for sending and retrieving text messages is to be developed. A client (eg app on a smartphone) communicates with an application on a web server running a database of user data (username and password) and messages (user name of the sender, user name of the recipient, message text). The client should be able to perform the following actions: Register a new user Log in...

Tig. 1 2. Consider the scenario shown below where (from the bottom up), you notice three hosts and a local logging server (that stores information that is sent to it) are connected to a router and to each other by a 100 Mbps link, with a near-zero ms propagation delay. That router in turn is connected to another router over a 30 Mbps link with a 50 ms propagation delay, and that latter router is connected to two remote logging...

PING: Finding Other Computers The PING sends a small packet to any computer on the Internet to show you how long it takes the packet to travel from your computer to the target computer and back again. You can ping a computer using its IP address or Web URL Not all computers respond to ping commands, so not every computer you ping will answer.

A computer store sells three types of microcomputers, brand A, brand B, and brand C. Of the computers they sell, 60% are brand A, 20% are brand B, and 20% are brand C. They have found that 15% of the brand A computers, 15% of the brand B computers, and 10% of brand C computers are returned for service during the warranty period. If a computer is returned for service during the warranty period, what is the probability that it...
