TCP/IP Hours 5 and 6

TCP/IP Teach Yourself TCP/IP in 24 Hours - Hours 5 and 6 Terms

QuestionAnswer
CIDR Classless Internet Domain Routing. A technique that allows a block of network IDs to be treated as a single entity.
Subnet A logical subdivision of the address space defined by a TCP/IP network ID
Subnet Mask A 32-bit binary value used to assign some of the bits of an IP address to a subnet ID. It identifies the network ID in a regular class address. All 1’s in the subnet mask = network / subnet ID
Supernet Mask A 32-bit value used to aggregate multiple consecutive network IDs into a single entity.
ACK A control flag specifying that the Acknowledgment Number field in the TCP header is significant
Acknowledgment Number field A field in the TCP header specifying the next sequence number the computer is expecting to receive. The acknowledgement number, in effect, acknowledges the receipt of all sequenced bytes prior to the byte specified in the ack number.
Active open A state in which TCP is attempting to initiate a connection
Checksum A 16-bit calculated field used to ensure detection of corrupted datagrams
Connection-oriented protocol A protocol that manages communications by establishing a connection between the communicating computers. TCP is an example.
Connectionless protocol A protocol that transmits data without establishing a connection with the remote computer. UDP is an example.
Control flag A 1-bit flag with special information about a TCP segment
Demultiplexing Directing a single input to several outputs
Destination port The TCP or UDP port number of the application on the destination machine that will be the recipient of the data in the TCP segment or UDP datagram
FIN A control flag used in the process of closing a TCP connection
Firewall A device that protects a network from unauthorized Internet access
Initial sequence number (ISN) A number that marks the beginning of the range of numbers a computer will use for sequencing bytes transmitted through TCP
Multiplexing Combining several inputs into a single output.
Passive open A state in which the TCP port is ready to receive incoming connections
Port An internal address that provides an interface from an application to a Transport layer protocol
Pseudo-header A structure derived from fields from the IP header that is used to calculate the TCP/UDP checksum and to verify that the datagram has not been delivered to the wrong destination due to changes in the IP header.
Resequencing Assembling incoming TCP segments so that they are in the order in which they were actually sent
Segment A package of TCP data and header information
Sequence number A unique number associated with a byte transmitted through TCP
Sliding Window A window of sequence numbers that the receiving computer has authorized the sending computer to send. The sliding window flow control method is used by TCP.
Socket The network address for a particular application on a particular computer, consisting of the computers IP address followed by the port number of the application. Ex. 192.168.5.4:80
Source port The TCP or UDP port number of the application sending a TCP segment or UDP datagram
Stream-oriented input Continuous (byte-by-byte) input, rather than input in predefined blocks of data
SYN A control flag signifying that sequence number synchronization is taking place. The SYN flag is used at the beginning of a TCP connection as part of the 3-way handshake
TCP A reliable connection-oriented Transport layer protocol in the TCP/IP suite.
3-Way Handshake A three step procedure that synchronizes sequence numbers and starts a TCP connection
UDP A non-reliable connectionless transport protocol in the TCP/IP suite.
Well-know port Predefined standard port numbers for common applications. Well-known ports are specified by IANA.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
