Fibre optic cabling, for example, operates at speeds that hubs are not designed to handle. However, the hub works on physical layer whereas switch operates on the data link layer. How switch statement is different from if else statement? All devices on a 10BASE2, 10BASE5, or any network using a hub risk collisions between the frames that they send, so all devices on one of these types of Ethernet networks are in the same collision domain and use CSMA/CD to detect and resolve collisions. Which was not possible earlier. It's very much possible to create a computer network based only on hubs, but there are a few reasons why this is not recommended, despite the fact they're cheaper than switches. Here, are cons/drawbacks of using Switch: Not as good as a router for limiting Broadcasts 1 mark for switch/hub/router 1 mark for server or workstation labelled correctly Workstation 3 m a rk s 3 4. An image of switch – Advantages of Switch. Hubs operate at the Physical Layer---Layer 1 of the Open Systems Interconnect (OSI) Reference Model. If the network is limited to a single building or group of buildings then it is described as a Local Area Network (LAN). 2. The 10/100Mbps available with a network switch allows devices on the network to reach their full capacity. Repeating hubs are considered part of the collision domain and for reliable operation of a shared Ethernet network, the network diameter must not exceed the collision domain (see Figure 1). Using hub save money because switches are costly then hub. What advantage does a switch have over a hub? Like hub, a switch never broadcast the packet to all the connected devices instead it forwards the packet to the specific device only. 5. Hope counts are unlimited.
