Expert Solution & Answer
Chapter 1, Problem P31P
a.
Explanation of Solution
Given,
The length of the message is 8 × 106 bits
The transmission rate of the link is 2 Mbps
Note:
Substitute, “8 × 106” for “Length” and “2 × 106” for “Transmission rate” is given below:
The time required to send the message from source host to first packet switch is
b.
Explanation of Solution
Note:
Substitute, “1 × 104” for “Length” and “2 × 106” for “Transmission rate” is given below:
The time required to move the first packet from source host to the first switch is,
c.
Explanation of Solution
Note:
Substitute, “1 × 104” for “Length” and “2 × 106” for “Transmission rate” is given below:
The time required to move the first packet from source host to the first switch is,
d.
Explanation of Solution
Reasons to use message segmentation:
- In case of bit errors and single bit errors, the entire message must be retransmitted. Hence, message segmentation is used to eliminate retransmission...
e.
Explanation of Solution
Drawbacks of message segmentation:
- Packets present in the link must be kept in a specified sequence at the destination...

(Short-answer) b. Continue from the previous question. Suppose part of the data you extracted from the data warehouse is the following. Identify the missing values you think exist in the dataset. Use Column letter and Row number to refer to each missing value in the dataset. Please write down how you want to address each particular missing value (you can group them if they receive same treatment). For imputation, you do not need to calculate the exact imputed values but just describe what kind of value you want to use to impute.
