Where a hub or switch is concerned with transmitting frames, a router’s job, as its name implies, is to route packets to other networks until that packet ultimately reaches its destination. 7. A Computer Network is a system of connected computers, peripherals and communication devices that can exchange data and share resources. What advantage does a switch have over a hub? This means that messages have to be transmitted out of every port of the hub, greatly degrading the efficiency of the network. Also called as intelligent hub as it stores the MAC and IP address both of the packet in the arp table. We can operate a network on Full Duplex because of switch. Supports VLAN's that can help in Logical segmentation of ports; Switches can make use of CAM table for Port to MAC mapping; Disadvantages of Switch. Each vlan is a separate broadcast domain. Both the Ethernet hub and the Ethernet switch are used for computer networking, but understanding how they differ in their message-passing will help you understand when to prefer a hub over a switch. Simple to troubleshoot because only one device is affected by a cable break between the switch and the device. 3. A hub operates in half-duplex, meaning that it cannot send and receive data at the same time. A hub also can modulate signal of the cable, if needed. Faster Read-write Speed Than HDD. The tree seems to share all the disadvantages of the bus and the star. Ethernet switches and hubs are both used to network file servers, printers and workstations together. C. it recognizes frame boundaries and destination MAC addresses of incoming frames D. Any two or more devices the switch connects are capable of causing a collision with each other. This maximizes security and efficiency of the network. In a hub, there was just one domain and no intelligence about what devices were connected to each port. 2. However, for this to happen, a switch must be used rather than a hub. For interoperatibilty between different links Auto negotiation should be enabled. As a hub, a switch is the connection point for the computers (and other devices) in a network. A switch is more intelligent than a hub. Monkey Business Images Ltd/Valueline/Getty Images. A hub allows you connect clients to share and conversations with a network protocol analyser. In computer networking, the most important essential thing that every student must know is the OSI model. If one VLAN is compromised, e.g with a virus, because the others are partitioned they will not be affected. Hub.

Bridge. • Broadcast Control: Broadcasts are required for the normal function of a network. One of the key features of a packet is that it not only contains data, but the destination address of where it’s going. A network switch connects devices together on a single computer network. 2. This maximizes security and efficiency of the network. 2. Like hub, a switch never broadcast the packet to all the connected devices instead it forwards the packet to the specific device only. THEORY. 5. The main advantage of a switch over a hub is that it can allow multiple simultaneous packet deliveries from different sources to different receivers. However, a switch is more efficient at passing along traffic. It helps you to reduce the number of broadcast domains. It's very much possible to create a computer network based only on hubs, but there are a few reasons why this is not recommended, despite the fact they're cheaper than switches. Decreased packet collisions. A hub is a generic connection device used to tie several networking cables together to create a link between different stations on a network. 1 mark for switch/hub/router 1 mark for server or workstation labelled correctly Workstation 3 m a rk s 3 4.

Amanda Rumble has been writing for online publications since 2000, primarily in the fields of computing and technology. You can sever cables to it without compromising the rest of the network, but it must remain functional for data movement to occur. So if you purchase an '8 port hub', you will be able to connect up to eight computers together. Its does by using the VLANs. A switch performs a similar role to a hub and a bridge but is more powerful. To know about switching, you first need to know why you needed Switches. ➨They help in reducing workload on individual host PCs. A hub sends every packet of data to every device, whereas a switch only sends a packet of data to the destination device. Cost: Because hubs are less complicated, they tend to cost less per port than switches. It is easy to turn ON. switch : A compound statement. It does not affect performance of the network seriously. When a house with different family members want to interconnect their computers to exchange information, an office wants to set up a network to provide internet access to all its computers or exchange files between its different branch offices, then networking is the way to go. Using ethernet you can easily achieve the speed of 10Gbps, especially with the latest twisted pairs. 2. It is cheaper. A collision domain is a set of devices whose frames could collide. It has a much better range than a 5 GHz wireless network. A collision domain is a set of devices whose frames could collide. The primary difference between a hub and switch is how the nodes communicate with the network. Also called as intelligent hub as it stores the MAC and IP address both of the packet in the arp table. High-speed applications, such as streaming audio and video, also require a fast speed to operate without performance or quality differences.
