OSI LAYERS Flashcards
Is an abstract description for layered communications and computer network protocol design.
OSI Model
(Open System Interconnection Reference Model)
is the user interface that internet users interact with to send or receive data through email, online games, peer to peer file transfer, and other applications.
Application Layer
It translates the commands received from the application layer into universal, well-known networking formats. Think of it as a more effective version of Google Translate but for networks. This is the layer where data encrýption and character set Conversion OCCur.
Presentation Layer
In order for a packet to reach its destination, the ______ establishes a“mechanism for opening, closing and managing a session between end-user application processes and Tesponses”.The sessio layer nakes it possible to establish an open communication line to send the requested packets.
Session Layer
It does not only defines how data is sent, but also provides validation and firewall security.
Transportation Layer
It seeks for the best-known path to route information to reach its destination similar to searching for an address on a GPS.
Network Layer
It ensures that a transmission occurs without any errors. The One of the major _____consists of two sub-layers, functions of the data link Logical Link Control (LLC) and the Media layer 1s to provide a Access Control (MAC), that ensure a successful physical MAC address so transmission across different mediums.
Data Link Layer
The ____ consists of the physical hardware components in a components in a Local Area Network (LAN) network. In this final step, our now such as networking hardware and Ethernet starving customer will receive her cables. Cabling issues in the physical layer delivery. Sometimes emerge due to the wrong types of cables (straight through vs. cross over cables) Common protocols: Fast used or faulty cables.
