Step by step
Solved in 2 steps
- Describethe two types of data link protocols, i.e., character-based and bit-oriented, and the main differences between them.Write the answer of each of the following questions in brief with respect to OSI layer model: Reliable process-to-process message delivery? Route selection? Defines frames? Transmission of bit stream across physical medium?Give a rundown of the two well-known data transmission protocols that are made available by the Transport Layer.Please provide a brief explanation of each service and identify the kind of applications that might make use of them.
- Write the answer of each of the following questions in brief with respect to OSI layer model: 1. Reliable process-to-process message delivery Answer 2. Route selection Answer 3. Defines frames Answer 4. Transmission of bit stream across physical mediumWrite the answer of each of the following questions in brief with respect to OSI layer model: Transmission of bit stream across physical medium Answer: *This question has already been submitted, but this question remains unansweredA bit string, 0111101111101111110, needs to be transmitted at the data link layer. What is the string actually transmitted after bit stuffng? Write a computer code to do this job.
- What is the primary responsibility of the physical layer? To transmit individual bits across a medium To transmit data between two directly connected network devices To transmit data between two hosts across a network of many interconnected devices To provide end-to-end services such as reliable delivery, flow control, and persistent connection To provide a service to the end user such as delivering a web page or transferring a file Suppose users share a 20 Mbps link. Also suppose each user transmits continuously at 2 Mbps when transmitting, but each user transmits only 30 percent of the time. If circuit switching is used, how many users can be supported? 5 10 2 20 What is the network address of the IP address 207.45.155.108/20? How many host addresses can you have in the following subnet 201.18.23.0/29? Assume that all addresses in this block can be used as a host address. How long does it take to send a 100MB file from host A to host B over a circuit-switched network?…How does "full duplex" communication at the Physical Layer enhance data transfer rates compared to "half duplex"?For what reason does the transport layer offer the network layer the ability to packetize data? What issue exists at the transport layer if segments require datagram encapsulation to be transmitted?
