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.

Difference between: Hub, Bridge,Switch and Router?

A most common question asked by interviewer in a interview of desktop support, IT support, System admin and Network admin is difference between Hub and Bridge, Difference between Switch and router and vice versa. Hub — A hub works is to connect our network devices such as computer, printer etc. When Hub receives data from one system it broadcast to every connected port except the one from which receiving data. Hub has many demerit- It uses more bandwidth of the network due to unnecessary network broadcast. Due to this data collision may occur which may corrupt your data or may need to send again.

A network bridge is a computer networking device that creates a single, aggregate network from multiple communication networks or network segments. This function is called network bridging. Routing allows multiple networks to communicate independently and yet remain separate, whereas bridging connects two separate networks as if they were a single network. The main types of network bridging technologies are simple bridging, multiport bridging, and learning or transparent bridging. Transparent bridging uses a table called the forwarding information base to control the forwarding of frames between network segments. The table starts empty and entries are added as the bridge receives frames.

Tutorial of Differences between Hub, Bridge, Switch and Router

A network switch also called switching hub , bridging hub , and, by the IEEE , MAC bridge [1] is networking hardware that connects devices on a computer network by using packet switching to receive and forward data to the destination device. 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.

A Hub is the simplest of these devices. In general, a hub is the central part of a wheel where the spokes come together. This leads to inefficiencies and wastage.

Network switch

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.

Institutions — including, companies, universities and high schools — typically consist of many departments, with each department having and managing its own Ethernet LAN. Naturally, an institution will want its departments to interconnect their departmental LAN segments. In this section, we consider a number of different approaches in which LANs can be connected together. We'll cover three approaches, hubs, bridges, and switches in the following subsections. All three of these approaches are in widespread use today.
