Compare GBN, SR, and TCP (no delayed ACK). Assume that the timeout values for all three protocols are sufficiently long such tha

kvv77 [185]

Answer and Explanation:

For Go-Back-N:

Host A sent total number of segments is 9.The initial segment numbers are 1,2,3,4,5 and re-sent the segemnts 2,3,4 and 5 because 2nd segment was lost.

Host B sent the number of ACKs are 8.Host B sent ACKs 1 by four times because 2nd segment was lost and sent 4ACKs with sequence numbers 2,3,4 and 5

selective repeat:

Host A sent total number of segments is 6.The initial segment numbers are 1,2,3,4,5 and re-sent the segemnts 2 because 2nd segment was lost.

Host B sent the number of ACKs are 5.Host B sent four ACKs with sequence numbers 1,3,4,5 and re-sent ACK2 with sequence number 2 because 2nd segment was lost.

TCP :

Host A sent total number of segments is 6.The initial segment numbers are 1,2,3,4,5 and re-sent the segemnts 2 because 2nd segment was lost.

Host B sent the number of ACKs are 5.Host B sent four ACKs with sequence number 2 and There is one ACK with sequence number 6.TCP always send an ACK with expected sequence number

b) If the timeout values for all three protocol are much longer than 5*RTT,then TCP protocol successfully delivers all five data segments in shortest time interval.

Try making a character (string) variable and a logical variable . Try creating a variable with a "missing" value NA. You can cal

quester [9]

Answer:

The solution code is written in R script.

#string variable
character_str<- "Hello World"
#logical variable
logic <- a > b
#Missing value
myVec <-c(1, 2, 3, NA)
#Use class to check data type
class(character_str)
class(logic)
class(myVec)

Explanation:

A string variable is a variable that hold a string (the letters enclosed within quotation marks) (Line 2)

A logical variable is a variable that hold a logical value (either True or False). The logical value is created by comparing two variables (Line 5).

In R, missing value is an unknown value which is represented by NA symbol (Line 8).

We can use in-built method class  to check for the variable type in R (Line 11-13). For example, the output of class(character_str) is "character"
