File Name: difference between switch and router and hub ppt to .zip
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 switch can use Full- Duplex. Multiple Collision Domains. Save Bandwidth in comparison of Bridge. Increased security. Router- A router used to connect two network, Internal and external networks. Layer 3 device. Few ports in compare of witch. More security we can define by using it to secure our network. How to activate windows 10 OS step by step? How to create a new Ad unit in AdSense.

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. As a network product, a hub may include a group of modem cards for dial-in users, a gateway card for connections to a local area network for example, an Ethernet or a token ring , and a connection to a line. Hubs are used on small networks where data transmission is not very high. In telecommunication networks, a bridge is a product that connects a local area network LAN to another local area network that uses the same protocol. Having a single incoming and outgoing port and filters traffic on the LAN by looking at the MAC address, bridge is more complex than hub.

When computers, network devices or other networks are required to be connected, hubs, switches and routers are the bridges to link them together. All the three.
Router and switch both are the connecting devices in networking. A router is used to choose the smallest path for a packet to reach its destination. A switch stores the arrived packet, process it to determine its destination address and forwards the packet to a specific destination. The basic difference between a router and a switch is that a router connects different networks together whereas, a switch connect multiple devices together to create a network.
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.
Understand the different types of switches available so you can make the right choices for your small business. Understanding the types of network switches will help you find the right solution to keep up with your changing business requirements. Think about the categories of switches as well as specific switch benefits as you explore your options.
Data center evolution. The data center is at the foundation of modern software technology, serving a critical role in expanding capabilities for enterprises. The traditional data center uses a three-tier architecture, with servers segmented into pods based on location, as shown in Figure 1. The architecture consists of core routers, aggregation routers sometimes called distribution routers , and access switches.
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.
In the list of the networking devices, NIC stands on the first place.

Hubs do not differentiate between frame types, and thus will always forward unicasts, multicasts, and broadcasts out every port but the originating port. Ethernet.Febes C. 16.05.2021 at 20:05
