Which layer of the OSI model is responsible for logical addressing and routing?

Which layer of the OSI model is responsible for logical addressing and routing?

the Network Layer
Layer 3 is responsible for routing network messages through the network. An important function of the Network Layer is logical addressing.

Which layer in the Open Systems Interconnection OSI model is responsible for adding a logical address to a packet?

Data Link Layer
Data Link Layer: It is IP address understandable layer, which helps you to define logical addressing so that any endpoint should be identified. The layer also helps you implement routing of packets through a network. It helps you to define the best path, which allows you to take data from the source to the destination.

Which layer is responsible for establishing end end connection?

transport layer Layer 4
The transport layer Layer 4 is responsible for end-to-end communication between the two devices.

Which OSI layer is responsible for logical addressing?

The network layer
The network layer implements logical addressing for data packets to distinguish between the source and destination networks.

Which layer is called a port layer in Open Systems Interconnection OSI model?

Transport layer
At sender’s side: Transport layer receives the formatted data from the upper layers, performs Segmentation, and also implements Flow & Error control to ensure proper data transmission. It also adds Source and Destination port numbers in its header and forwards the segmented data to the Network Layer.

Which layer of the Open Systems Interconnection OSI model utilizes addresses that uniquely identify a physical device?

There are two distinct sublayers within Layer 2: Media Access Control (MAC): the MAC sublayer handles the assignment of a hardware identification number, called a MAC address, that uniquely identifies each device on a network. No two devices should have the same MAC address.

Which layer is responsible for creating and terminating connections between the client application and the host computer?

Explanation: The role of Transport layer (Layer 4) is to establish a logical end to end connection between two systems in a network. The protocols used in Transport layer is TCP and UDP.

What is logical address in operating system?

In computing, a logical address is the address at which an item (memory cell, storage element, network host) appears to reside from the perspective of an executing application program. A logical address may be different from the physical address due to the operation of an address translator or mapping function.

What does the Open Systems Interconnection model mean?

This article explains the Open Systems Interconnection (OSI) model and the 7 layers of networking, in plain English. The OSI model is a conceptual framework that is used to describe how a network functions.

Which is the second layer of the OSI model?

The second layer of the seven layers of Open Systems Interconnection (OSI) network model is called the Datalink layer. The Data Link layer resides above the Physical layer and below the Network layer.

How does the OSI model help network operators?

The OSI model helps users and operators of computer networks: 1 Determine the required hardware and software to build their network. 2 Understand and communicate the process followed by components communicating across a network. 3 Perform troubleshooting, by identifying which network layer is causing an issue and focusing efforts on that layer.

Which is a part of the Logical Link Control layer?

This layer is composed of two parts—Logical Link Control (LLC), which identifies network protocols, performs error checking and synchronizes frames, and Media Access Control (MAC) which uses MAC addresses to connect devices and define permissions to transmit and receive data.
