TCP (Transmission Control Protocol) Flashcards

Front

TCP (Transmission Control Protocol) is used in networking and is similar to the OSI model.

Back

TCP/IP protocol consists of four layers: Application, Transport, Internet, Network Interface.

Front

TCP is connection-based.

Back

TCP requires establishing a connection between a client and a server before data is sent.

Front

Three-way handshake

Back

A process in TCP that ensures data sent will be received on the other end.

Advantages of TCP

Back

1. Guarantees the integrity of data. 2. Capable of synchronizing two devices to prevent data flooding. 3. Performs more processes for reliability.

Front

Disadvantages of TCP

Back

1. Requires a reliable connection; data must be re-sent if not received. 2. A slow connection can bottleneck devices. 3. Slower than UDP due to more computing work.

Front

Source Port

Back

The port opened by the sender to send the TCP packet, chosen randomly from available ports (0-65535).

Front

Destination Port

Back

The port number an application or service is running on the remote host, not chosen at random.

Front

Source IP

Back

The IP address of the device sending the packet.

Front

Destination IP

Back

The IP address of the device the packet is destined for.

Front

Sequence Number

Back

The random number given to the first piece of data transmitted when a connection occurs.
