question about TCP/IP?

Question

TCP stands for Transmission Control Protocol, while IP stands for Internet Protocol.

Why does it always combine the name TCP/IP?

Answer 1

IP runs at layer 3 of the OSI Model

TCP runs at layer 4 of the OSI Model



Layer 3 connects two different computers across a network or the Internet



Layer 4 provides error detection and sequencing of data packets. It puts all the bits of information together in the proper order and retransmits data if any piece gets lost or corrupted along the way to its destination.



You cannot have TCP without IP, but you can have IP without TCP (e.g., UDP over IP).



See Wikipedia OSI Model for a more detailed explanation.

Answer 2

It is a protocol stack. You need them both to be able to access the internet.



TCP - gets data from a network to another.

IP - It allows the internet to actually work.



Together the two make the internet. You cant go from go from network to another without giving an address to the network (ip). The TCP standard allows the communication to actually function so one IP can communicate with another IP. You have your mac address to specify which computer, hub, router is what. You have your private IPs to allow delivery of packets from a router to internal hosts. TCP/IP is a very important set of protocols and without them you and I would not be talking.

Answer 3

Those two are part of a subset of communications protocols used for the Internet. The entire communications suite is known as TCP/IP because those were the first two defined as part of the standard.

Answer 4

Tcp handles the transmission and decoding of the message, while Ip handles the addressing of the message. These two are combined because if they weren't the message portion wouldn't know where it was supposed to go.

Answer 5

it means that u can either have 1 of da 2 or both
