What is the 7th layer of the OSI networking model called?
The Application Layer
This layer supports Applications and end user processes.
What is the 6th layer of the OSI networking model called?
The 6th layer of the OSI networking model is called the Presentation Layer.
This layer formats and encrypts data to be sent across the network.
What is the 5th layer of the OSI networking model called?
The 5th layer of the OSI networking model is called the Session Layer.
This layer establishes, manages, and terminates connections between applications. It deals with session and connection coordination.
What is the 4th layer of the OSI networking model called?
The 4th layer of the OSI networking model is called the Transport Layer.
This layer is responsible for end to end error recovery and flow control.
What is the 3rd layer of the OSI networking model called?
The 3rd layer of the OSI networking model is called the Network Layer.
This layer provides for data transmission, routing, and forwarding as well as error handling, congestion control and packet sequencing.
What is the 2nd layer of the OSI networking model called?
The 2nd layer of the OSI networking model is called the Data Link Layer.
Data packets at this layer are encoded and decoded into bits. It handles errors in the physical layer, flow control, and frame synchronization. It has 2 sublayers: LLC and MAC
What is the 1st layer of the OSI networking model called?
The 1st layer of the OSI networking model is called the Physical Layer.
This layer provides the hardware means of sending the data in a stream of electrical impulses via cables, radio waves, etc.
What does MAC stand for? And what Layer on the OSI networking model does it reside in?
MAC stands for Media Access Control and it resides in the 2nd (Data Link) layer of the OSI networking model.
This sublayer on the Data Link (2nd) layer of the OSI networking model controls how a computer gains access to data and permission to transmit it.
What does LLC stand for? And what layer on the OSI networking model does it reside in?
LLC stands for Logical Link Control and it resides in the 2nd (Data Link) layer of the OSI networking model.
This sublayer on the 2nd (Data Link) layer of the OSI networking model controls frame synchronization, flow control, and error checking.
What does the acronym OSI stand for? And what is its definiton?
The acronym OSI stands for Open System Interconnection and is a model defining a networking framework for implementing internet communication protocols in 7 layers.
