They support virtual Local Area Networks (LANs) and thus help in logical segmentation.They increase the network’s available bandwidth and can improve the network’s performance.The following are the advantages of network switches: Then, the switch sends the data packet through the appropriate ports that lead to the destination device. When a data packet enters a network switch, the switch reads its header to find its media access control (MAC) address and determine its destination. A switch sends data only to the single device it is intended for. It receives data packets and sends them to the correct device by switching packets. It works at layer 2 of the Open Systems Interconnection (OSI) model, which is the data link layer. See More: How Does an Edge Network Work and What Does Its Future Hold? AT&T’s Theresa Lanowitz Answers What is a network switch?Ī network switch is an appliance that lets the many devices on a computer network connect to each other. They operate on routable network protocols.They are relatively slow as they process data packets at three layers.Their firmware contains several vulnerabilities that cyber attackers can easily exploit.They are more expensive than other networking devices.However, the following are the disadvantages of routers: Since they are interoperable with other networking devices, such as modems, one may use routers in conjunction with those other devices.They provide sophisticated routing, traffic isolation, and flow control.They use dynamic routing algorithms to determine the best path across the internetwork, thus minimizing traffic load.They reduce network traffic by creating collision and broadcast domains.They allow communication between different networking architectures, such as Ethernet and token rings.The following are some of the benefits that routers offer: The device then consults the information stored in its routing table to route the data packet along the route to get it to its final destination as quickly and effectively as possible before sending it on to the subsequent network. When a router receives a data packet, the router scans the network address data inside the packet header to identify where the data packet is headed. It also manages traffic between the computer networks by forwarding data packets to their specified internet protocol (IP) addresses.
A router operates at layer-3 of the open systems interconnection (OSI) stack and allows several devices to use the same internet connection. The term “router” refers to networking equipment moving data packets from one computer network to another.
Before we compare and contrast the two, let’s first have a basic understanding of switches and routers and the benefits and drawbacks associated with each. Switches and routers are both networking hardware that form an essential part of IT infrastructure.
