2024年8月13日 · Network Switch works on Layer 2 of the OSI Model. The router is primarily a device of Layer 3 of the OSI Model. The resource is shared among multiple devices with the help of a single LAN using a network switch.

2025年1月20日 · The OSI Model is a seven-layer framework that standardizes how different computer systems communicate over a network, facilitating data transmission and troubleshooting by defining specific functions for each layer.

A network switch is a device that operates at Layer 2 (Data Link layer) of the OSI model. It connects devices on a LAN and forwards data packets only to the intended recipients, unlike a hub...

A network switch is a multiport network bridge that uses MAC addresses to forward data at the data link layer (layer 2) of the OSI model. Some switches can also forward data at the network layer (layer 3) by additionally incorporating routing functionality.

2023年12月23日 · Within the OSI (Open Systems Interconnection) model, the network switch operates primarily at the data link layer (Layer 2). This layer is pivotal in ensuring reliable node-to-node communication and serves as a bridge between the physical layer and the network layer.

2020年12月21日 · 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. In plain English, the OSI model helped standardize the way computer systems send information to each other.

2024年10月23日 · The difference between a switch being a “Layer 2” switch and a “Layer 3” switch is whether it facilitates a routing function (routing happens at the “Internet Protocol” layer, or Layer 3 on the OSI model).

A network switch is a Layer 2 device on the OSI model. A router is primarily a Layer 3 device. A router moves data between two or more computer networks, while a switch facilitates the sharing of resources by connecting multiple devices on a single LAN.

Network switches can operate at either OSI layer 2 (the data link layer) or layer 3 (the network layer). Layer 2 switches forward data based on the destination MAC address (see below for definition), while layer 3 switches forward data based on the destination IP address. Some switches can do both. Most switches, however, are layer 2 switches.

2023年12月21日 · In this article, we will explore the typical operations of a network switch across the layers of the OSI model. By examining the functionalities of the switch at each layer, we can gain a comprehensive understanding of its role in network communication and data transmission.
