What is a Layer 3 PDU?
What layer is responsible for routing messages through an internetwork in the TCP/IP model Explanation:The TCP/IP model consists of four layers: application, transport, internet, and network access. Of these four layers, it is the internet layer that is responsible for routing messages.Internet Layer – The Internet Layer provides logical addressing. More specifically, the internet layer relates physical addresses from the network access layer to logical addresses.application layer

Question Answer
At which OSI layer is a destination port number added to a PDU during the encapsulation process transport layer
At which OSI layer is data added to a PDU during the encapsulation process application layer

Which layer provides routing : Network layer

3. Network layer: Handles the routing and sending of data between different networks. The most important protocols at this layer are IP and ICMP.

What are layer 3 logical addresses

Logical Addressing: Layer 3 uses IP (Internet Protocol) addresses to uniquely identify devices. These are logical addresses, and addressing schemes are set up to maximize the network topology and ensure secure and efficient data transfer.

What is layer 1 vs Layer 2 vs layer 3 : Layer 1 is the core architecture, Layer 2 adds functionalities, and Layer 3 hosts applications built on these functionalities. These layers differ in key aspects, such as consensus mechanisms, scalability solutions, transaction speed & price, and security features.

The Layer 4: transport layer PDU is the segment or the datagram. The Layer 3: network layer PDU is the packet. The Layer 2: data link layer PDU is the frame. The Layer 1: physical layer PDU is the bit or, more generally, symbol.

Is routing a Layer 2 or 3

Traditionally, the network device most associated with Layer 3 has been the router, which allows you to connect devices to different IP networks.Layer 3, known as the Network Layer routes data packets to specific nodes identified by IP addresses. Visibility amongst nodes is point-to-point. As its function suggests, routers are a common layer 3 example.A Layer 3 switch is basically a switch that can perform routing functions in addition to switching. A client computer requires a default gateway for layer 3 connectivity to remote subnets. When the computer sends traffic to another subnet, the destination MAC address in the packet is for the default gateway.

High throughput, high port density, and high traffic speed is enabled by layer 3 switches' hardware configurations and the ability to combine switching and routing capabilities. Routers typically use software-based routing, which can be slower but offers more advanced routing.

Is wifi a Layer 2 or 3 : Layer 1 Equipment

The physical transmission aspects of Wi-Fi, Bluetooth, Microwave, and other over-the-air technologies fall under this layer.

How does the Layer 3 PDU relate to the Layer 2 PDU : So, in the above case, person 2 should know about the packet (layer 3 PDU), in order to reach person 3 and can it pass the data to person 1 using frame (layer 2 PDU). So, on the whole, data is encapsulated in each layer. So, both packets and frames are encapsulated and used for within or outside the network.

What is the PDU of Layer 2

A protocol data unit (PDU) is and open-system interconnection (OSI) term used in telecommunications. PDU relates to the initial four layers of the OSI model as follows: Layer 1 (Physical Layer) = Bit | Layer 2 (Data Link Layer) = Frame | Layer 3 (Network Layer) = Packet | Layer 4 (Transport Layer) = Segment.

segment

For example, in Layer 4, the PDU of the Transport Layer is referred to as a segment based on TCP (Transmission Control Protocol) and with UDP (User Datagram Protocol) PDU is referred to as a datagram. Layer 3, the PDU of the Network Layer is referred to as a packet.Layer 2 switches offer limited to no routing capabilities within network segments such as VLANs. Layer 3 switches offer routing between different network segments. Limited scalability.

What is layer 3 also known as : The most significant protocol at layer 3 (also called the network layer) is the Internet Protocol, or IP.
