network layers :(
Karten in diesem Stapel (9)
- 1physical layerthe actual hardware
- 2data link layerdata transfer method (802x ethernet). Puts data in frames and ensures error free transmission. Also controls the timing of the network transmission. Adds frame type, address, and error control information. IEEE divided this layer into the two following sublayers
- 3network layerIP network protocol. Routes messages using the best path available
- 4transport layerTCP, UDP. Ensures properly sequenced and error free transmission
- 5session layerthe user's interface to the network. Determines when the session is begun or opened, how long it is used, and when it is closed. Controls the transmission of data during the session. Supports security and name lookup enabling computers to locate each other
- 6presentation layerASCII or EBCDEC data syntax. Makes the type of data transparent to the layers around it. Used to translate date to computer specific format such as byte ordering. It may include compression. It prepares the data, either for the network or the application depending on the direction it is going
- 7application layerprovides services software applications need. Provides the ability for user applications to interact with the network
- 8logical link control (LLC)maintains the Link between two computers by establishing Service Access Points (SAPs) which are a series of interface points
- 9media access control (MAC)used to coordinate the sending of data between computers (hardware)
