TCP/IP Model Flashcards
TCP/IP Model
Transmission Control Protocol and Internet Protocol, Set of communication protocols developed by Dod, which is a 4 layer model, top down, 4 to 1, designed specifically for the TCP/IP Stack
TCP
Transmission Control Protocol, connection oriented, ensures information is transmitted accurately by establishing a virtual connection between the sender and receiver.
Layer 4
Application layer, corresponds to the Application layer, presentation layer, and session layer in the OSI model
Lay 4 Protocols
TCP Protocol s like FTP, HTTP
Layer 3
Transport Layer and this directly correlates with Transport layer 4 in the OSI model. Handles data transmission between hosts
Layer 3 Protocols
TCP (Transmission control protocol) and UDP (User Datagram Protocol)
Layer 2
Internet Layer. Corresponds to layer 3, the network layer in the OSI model.
Layer 2 Protocols
IP (Internet Protocol) internet work in general, routing, etc. Delivers data packets from one host to another
Layer 2 Protocol Data Unit
Packet
Layer 3 Protocol Data unit
Segment
Layer 4 Protocol Data Unit
Data
Layer 1 Protocol Data unit
Frame and Bits, this combines those processes but does not define a process for it
Layer 1
Network Interface (Link Layer). Doesn’t perfectly correlate with the Data Link later or the Physical later of the OSI model.
Difference between TCP/IP and OSI model
TCP/IP Model is a representation of the TCP/IP stack of Protocols that already exist, a reference.
OSI Model is intended to be a guide for the creation of networking protocols and standards, a guide.
A TIN
TCP/IP comes in “a tin” Application, Transport, Internet, Network (Link Layer), top down, 4 to 1.
