difference between hub and switch and router

A switch is a control unit that turns the flow of electricity on or off in a circuit. Hubs, Switches, Routers in a Nutshell. Router vs Switch vs Hub: The Devices Defined. Besides the inherent protection features provided by the NAT, many routers will also have a built-in, configurable, hardware-based firewall. The switch works in the data link layer and network layer of the OSI model. Another advantage of the Routers over Hub and Switch is the Firewall. Hub works in the physical layer of the OSI model. 2. It contains multiple ports so when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets. The Lines Continue to Blur. With modern advancement, the router these days are coming with multiple RJ45 ports for handling large no. Hub vs. Switch. For example, 4 computer systems within a network namely A, B, C, and D. If A intends to send a message to C, then B and D will not be notified and the message will only be accessible for C only. The functions of the three devices the router, switch … Akshay Thapliyal is the Co-founder of TechUntold and mainly looks into the strategic planning at TechUntold. It acts as a pivot point which connects the WAN (Wide Area Network) to the (Local Area Network). It provides a node to node data transfer which enables it to establish and dismiss a connection between 2 computers within a network. So a Firewall is installed in the router to protect the information of the end users from various cyber attacks. So the data only arrives at the intended destination. Whenever we listen to the term network, there are some specific devices that come to our mind like routers, servers etc. Ethernet switches and hubs can be connected to a router with multiple PC ports to expand a LAN. Additionally, a 10/100Mbps hub must share its bandwidth with each and every one of its ports. Hub have maximum 4 ports. The Hub works on the first layer of the OSI model i.e. difference between hub, bridge, switch and router common network environments, connectivity and security issues 07/01/2015 akmalcikmat 2. The crucial difference between router and switch is that a router interconnects various switches with their respective networks. Frames carry your data. For IT students always confused with the word “hub, bridge, switch and router”. It then forwards them to other ports so that they can reach the connected devices. It provides a node to node data transferability to the end users. So regardless of the number of PCs transmitting, users will always have access to the maximum amount of bandwidth. Switches merely pass the data along to the destination; hubs broadcast it to all connected endpoints, while routers read and process the data in order to determine where it needs to go. We need to create separate channels to distinguish the traffic for each specified nodes or devices. Routers, on the other hand, are simplified computers that can control the flow of data that passes through it. As switches become smarter, they are taking on some of the tasks that used to require a router. Integrated routers are blurring the functional lines between routers, switches, and hubs. In networks the switch is the device that filters and forwards packets between LAN segments. Hub A hub is generally a multi port repeater. In addition, they usually include a Dynamic Host Configuration Protocol (DHCP) server, Domain Name Service (DNS) proxy server and a hardware firewall to protect the LAN from malicious intrusion from the Internet. These three are computer networking devices, which are used to connect two or more computers across a single network, or across multiple networks.
