The connection establishment process actually accomplishes
several things as it creates a connection suitable for data
exchange:
o Contact and Communication: The client and server make
contact with each other and establish communication by
sending each other messages. The server usually doesn't even
know what client it will be talking to before this point, so
it discovers this during connection establishment.
o Sequence Number Synchronization: Each device lets the
other know what initial sequence number it wants to use for
its first transmission.
o Parameter Exchange: Certain parameters that control the
operation of the TCP connection are exchanged by the two
devices.

What is a 1-bit flag in the TCP header used to indicate the initial value of the sequence number?
The SYN flag is a 1-bit flag in the TCP header used to indicate the initial value of the sequence number. It is only set in the first two segments of the three-way TCP connection establishment sequence.
What type of connection does http use?
HTTP works over a TCP connection.HTTP works over a TCP connection.HTTP works over a TCP connection.HTTP works over a TCP connection.
Why tcpip is clubbed together despite working in different osi layers?
TCP/IP is just used to show the whole group of protocals used in sequence. Different protocals on different layers work together to send data over a network connection. It if wasn't for the TCP/IP sequence, you would not be seeing this message right now. TCP/IP is just used to show the whole group of protocals used in sequence.

What is the function of the tcp three-way-handshake?
It synchronizes both ends of a connection by allowing both sides to agree upon initial sequence numbers.
What do network hosts send to each other to create a tcp connection?
syn segments containing initial sequence numbers ack confirmations of syn receipt
What is TCP subprotocol?
Connection-oriented
When is UDP preferred to TCP?
UDP and TCP both are transport layer protocols. UDP is connection less and TCP is connection oriented. UDP is preferred over TCP when large amount data is to be sent like on skype or video conferencing .
How many TCP segments flow between two computers to establish a TCP connection?
Three
Difference TCP and UDP?
TCP is the protocol of network layer, It is connection oriented protocol. UDP is the protocol of network layer, It is connection less protocol.
What protocols are supported by TCP wrappers?
tcp based protocols,internet protocol,sometimes file transfer protocol also supported by tcp wrappers. tcp is reliable and connection oriented.
Why should telnet to UDP port fail?
A single port can be configured to listen for UDP or TCP inbound connection requests (or both). Telnet uses TCP. So when you telnet to a specific IP:port, telnet will attempt to make a TCP connection. If there is no TCP listener on the port you specify, then the connection request will be refused. It matters not if you have a UDP listener on the port. Telnet will not be able to establish a connection to a UDP port.
Why does the TCP use a sequence number in the header?
To reassemble the segments into data.
