File Name: what is difference between hub and switch .zip
A Hub is a networking device that allows one to connect multiple PCs to a single network. A switch is a control unit that turns the flow of electricity on or off in a circuit.
The key difference between hubs, switches and bridges is that hubs operate at Layer 1 of the OSI model, while bridges and switches work with MAC addresses at Layer 2. Hubs broadcast incoming traffic on all ports, whereas bridges and switches only route traffic towards their addressed destinations. Hubs provide a dedicated physical connection for every device, which helps reduce the possibility that a failure of one computer will cause all computers to lose connectivity. However, because a hub is still a shared bandwidth device, connectivity is limited to half-duplex. Collisions remain an issue as well, so hubs do not help improve the performance of the network.
Hubs and switches are different types of network equipment that connect devices. They differ in the way that they pass on the network traffic that they receive. This type of device simply passes on repeats all the information it receives, so that all devices connected to its ports receive that information. Hubs repeat everything they receive and can be used to extend the network. However, this can result in a lot of unnecessary traffic being sent to all devices on the network.
The Hub and Switch are the networking devices which appear to be similar and physically used as a star topology. However, there are several differences between Hub and switch. The prior difference is that logically the hub works like a bus where the same signal is transmitted to all the connections. On the other hand, the switch can provide the communication between any pair of ports. As a result, all the ports in the hub belong to the same collision domain while in switch the ports are operated on the separate collision domain. Number of ports 4 more or less 24 - 28 depending on the type of switch.

The hub itself is blissfully ignorant of the data being transmitted. For many years, hubs were quick and easy ways to connect computers in small networks.
Hub is operated on Physical layer. In this packet filtering is not available. It is of two types: Active Hub, Passive Hub. Switch: Switch is a network.
A Hub is a networking device that allows you to connect multiple PCs to a single network. It is used to connect segments of a LAN. A hub stores various ports, so when a packet arrives at one port, it is copied to various other ports. Hub works as a common connection point for devices in a network.
Hub and Switch A hub in networking allows users to connect more than one PC to a singular network. On the other hand, a switch forms the control unit responsible for keeping the flow of electricity. A hub in the computer network is also referred to as a multiport repeater.
Prerequisite — Network Devices Hub: Hub is a networking devices which is used to transmit the signal to each port except one port to respond from which the signal was received. Hub is operated on Physical layer. In this packet filtering is not available. It is of two types: Active Hub, Passive Hub. Switch: Switch is a network device which is used to enable the connection establishment and connection termination on the basis of need.
- Идем, - сказала она, вставая. - Выясним, права ли. Бринкерхофф проследовал за Мидж в ее кабинет.
Стратмор пожал плечами. - Танкадо выехал из Японии. Он собирался следить за ходом аукциона по телефону. Но нам известно, где. - И вы не хотите ничего предпринять.
