The OSI model is a simple framework for categorizing the different layers that make up network communication. There is no direct relation between the OSI model and any network address or protocol.
In fact, most network protocols don't fit neatly in to the OSI model. TCP/IP, for example, spans the data-link, network, and transport layers.

What is the function of the distribution layer in a campus network?
It distributes temporary IP addresses to each node.
How many types of addresses in each network node?
there are two types of addresses: network addresses and physical addresses
How does a network administrator use the osi model to isolate a network problem?
the network administrator uses the OSI model to troubleshoot network problem by verifying functionality of each layer, in many cases, troubleshooting the network problem requires the network administrator to isolate at what layer the network problem occurs. network administrators often describe networking problems by layer number, for example, a physical link problem is described as a layer 1 problem; a router problem is a layer 3.
What is difference between Transport layer and data link layer?
The data link layer handles communication between systems on the same local network. The network layer handles communication between systems on different local networks and allows those packets to be routed between the two. The data link layer would allow two machine on network a to talk to each other or two machines on network b to talk to each other. This communication takes place using the physical/MAC addresses of the machines. The network layer is what allows a machine on network a to talk to a machine on network b using logical address like IP addresses.
How many layer the Internet model consists of?
The Internet model consists of 4 layers: Application layer, Transport layer, Network layer, and Link layer. Each layer is responsible for specific functions in the process of sending data over the Internet.
Which osi layer addresses data messages?
The OSI model has seven layers whereby each layer has its function. The Data Link Layer is responsible for addressing data messages so that they reach their destination correctly.
What is the advantage of using switches rather than hubs?
Switches operate at the data link layer (Layer 2) of the OSI model and make forwarding decisions based on MAC addresses, leading to faster and more efficient data transmission compared to hubs, which operate at the physical layer (Layer 1) and simply broadcast data to all connected devices. Switches provide dedicated bandwidth to each port, reducing collisions and enhancing network performance.
What layer of the OSI model does a switch operate at?
Switches are commonly known as "Layer 2 (Data Link Layer)".3550 Switches: These switches are working under Layer 2 (Data Link Layer) and it is forward the packets through MAC Address, but if we convert these type of switches into Routers it will function in Layer 3 (Network Layer) of OSI model as it's forward the packets based on the IP addresses.2950 Switches: These switches are working under Layer 2 (Data Link Layer) of OSI model only and it is forward the packets through MAC Address.
What is layered network?
A layered network, or a network layer, is the set up of how data is sent over a network. Each layer has it's own responsibility by either capturing the data or routing it to a computer on the network.
What does OSI stand for?
OSI stand s for open system interconnection. It is a networking model given by ISO. It is introduced so that systems can communicate with each other regardless of their underlying architecture.
Devices found in each OSI model?
1. Repeaters (Operate at the OSI Physical Layer).2. Bridges (Operate at the OSI Data Link Layer).3. Routers {and Brouters} (Operate at the OSI Network Layer).
How many addresses has each President given on major network television?
