4.2 Flashcards
What are the three main characteristics of TCP
Connection oriented
Sequencing and check Sims
Flow control
Before TCP transmits data ensures that a connection or session established similar to making sure someone is listening at the other end of the phone. TCP uses a three-step process called a three-way handshake to establish a TCB connection
This is an example of what TCP characteristic
Connection oriented
TCP send a character strain called a check some TCP on the destination host that generates a similar strain is the two checks and failed to match the definition host asking stores to retransmit the data
This is example of what TCP characteristic
Sequencing and check sums
This is the process of gauging the Appropriate rate of transmission based on how quickly the recipient can accept data
This is example of what TCP characteristic
Flow control
Indicates the port at the sore host . Support allows a process to be available for incoming or outgoing data
16bits
Source port
Indicates the port at the destination host
16 bits
Destinations Port
Identifies daily segments position in the stream of data segments being sent
32 bitch
Sequence number
Confirm receipt of data via return message to the sender
32 bits
Acknowledgment number
Indicates the lines of the TCP header invites the header give me a minimum 20 bites to maximize the 60 in fort bite increments it also called the data offset field because it indicates the offset from the beginning of the segment until the start of the data carried by the segment
Four bit
TCP header length
Indicates to field reserve for later use
Six bits
Reserved
Indicates a collection of 61 bit fields or or flags at signal special conditions about other fields in the matter
Flags
Indicate how many bytes center can issue to a receiver before acknowledgment is received this field performs flow control preventing the receiver buffer from being deluged with bites
16 bits
Sliding window size
Allows receiving note Termine whether the TCP segment became corrupted during
16 bits
Check some
Indicates a location in the data field where urgent data resides
16 bits
Urgent pointer
Specialize special conditions such as the maximum segment size a network and handle
Between zero and 32 bits
