Faster response to missing packets

Lower overhead for the receiving system

Better performance when transmitting large files

Reduced overhead for transmissions

QUESTION 3

Why does TCP use a "window" when transmitting?

To make sure the sender produces as much data as the network card will allow

To make sure that the packets are smaller for better performance

To make sure that the sender does not send more data than the receiver can handle at a particular time

To make sure that it gets enough air

QUESTION 4

Network interface speed of the receiver

The class of the IP address of the sender

Network interface speed of the sender

Network delays

QUESTION 5

Which of the following is the TCP feature intended to help improve performance of interactive applications?

urgent mode

delayed acknowledgment

SYN flag

QUESTION 6

Which is a case where the Nagle algorithm would not be a good idea?

interactive applications

bulk data applications

small file transfers

http file downloads

TFTP

FTP

HTTP file downloads

Telnet

Explanation / Answer

Q1

4.  
Telnet

This protocol is used to interactively allow user to transfer data, load programs on remote computers

Q2

3.  
Better performance when transmitting large files

Delayed acknowledgement does not give advantage of better performance

Q3

3.
To make sure that the sender does not send more data than the receiver can handle at a particular time

Since TCP is reliable protocol it uses window for transmission.

Q4

2.  
The class of the IP address of the sender

IP address does have any roll in on the window, it can just inform the kind of network in which the receiver is present.

Q5

3.  
SYN flag

Q6

1.  
interactive applications
