Flashcards in Chapter 1: Compare the layers of the OSI and TCP/IP Models Deck (11)
Electrical, mechanical, and procedural aspects of communication
-Defines the standard for the "wire" (or fiber optic, or wi-fi)
Layer 2-Data Link
Defines how we put data (1s and 0s) on the wire.
The Data Link Layer is split into two parts
-Logical Link Control (LLC)
-Media Access Control (MAC)
Defines Logical addressing of computers and devices on the network.
-Logical addresses at the network layer are translated to physical at the Data Link Layer
-Primarily IP, but other protocols operate here
Defines the connection methods for communication.
-Some protocols established a guaranteed communication link, while others just whip their dick out for any devices "listening" on the wire
Mostly for the establishment, maintenance, and termination of computer sessions
-Generally just establishes a communication link.
Translating the stream of 1s and 0s on the wire
-Places information in a data stream the computer can understand
-Formats, encrypts, and compresses data
The protocol that your application uses to begin to put data on the system
-Common example would be HTTP
Network Interface Layer
Loosely aligns itself to the Physical and Data Link Layers (1 and 2)
Defines the wire and how data is put onto it
Loosely aligns itself with the Network Layer
-Logical communication links between computers, such as IPs
Largest example would be the Internet
Aligns itself to... The Transport Layer!
-TCP and UDP
