With SMTP, it is possible to send multiple mail messages over the same TCP connection.
True or False
With SMTP, it is possible to send multiple mail messages over the same TCP connection. True...
SMTP is used to ? a, transfer messages from one mail server to another b, transfer messages from mail server to a user agent c, to transfer messages from mail server to a user agent d, all of the above
Host A and B are directly connected with a 100Mbps link. There is one TCP connection between the two hosts, and Host A is sending to Host B an enormous file over this connection. Host A can send its application data into its TCP socket at a rate as high as 140 Mbps but Host B can readout of its TCP receive buffer at a maximum rate of 70 Mbps. Describe the effect of TCP flow control.
3.) (a) How is a TCP connection established? (b) What functions are performed by TCP? (c) How does congestion control affect message delay? (d) TCP is used at the Network Layer- True or False?
True or false. TCP provides a one-to-one, connection-oriented, reliable communication service. In contrast, UDP provides a one-to-one or one-to-many, connectionless, unreliable communication services.
How does a tcp server deal with identical messages arriving simultaneously on the same socket?
. Consider a TCP connection between Host A and Host B. Suppose that the TCP segments traveling from Host A to Host B have source port number 37 and destination port number 61. What are the source and destination port numbers for the segments traveling from Host B to Host A? . Suppose a process in Host C has a UDP socket with port number 6789. Sup- pose both Host A and Host B each send a UDP segment to...
suppose host A sends two TCP segments back to host B over a TCP connection. the first segment has sequence number 30; the second has sequence number 50. how much data is in the first segment? suppose that the first segment is lost but the second segment is lost but the second segment arrives at B. in the acknowledgment that host B sends to host A, what will be the acknowledgment number? (5 marks) in TCP/IP
1) In a typical TCP connection
establishment, the two flags used in the core handshake are the
_____ and _____ flags.
2) TCP uses _____ to manage the transmission between
senders and receivers that can send or receive differing rates to
make sure not to overwhelm machines that may be slower.
3) The transport layer protocol used by the TCP /
IP suite that does not provide guarantees on ordering or
confirmation of receipt of packets is called .
4)...
TCP headers and segmentation (B) 10. Which of the following flelds in the UDP header Is NOT found in the TCP header? source port destination port checksum length 11. The value of the acknowledgement field in a TCP segment defines Number of bytes to retransmit Number of bytes to receive Starting point of next bytes to receive in sequence Total number of bytes left 12. Suppose Host A sends one segment with sequence number 38 and 4 bytes of data...
It is not possible to send data to an API, only to receive it. True or False
