A Hub is a networking device that allows you to connect multiple PCs to a single network. It is used to connect segments of a LAN.
A Hub is a networking device that allows one to connect multiple PCs to a single network.
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.
How Does a Switch Work?
The reason for the confusion is understandable. Besides looking similar, all three devices pass along data traffic through connectors called ports. Plus, as these devices become more sophisticated, the functional differences between them continue to blur.
To understand the differences between hubs, switches, and routers, it helps to look at their fundamental roles as well as their levels of intelligence. A hub is the least intelligent of the three hardware devices.
It serves as a connection point for the computers and other devices such as printers in a network. A hub simply passes along the traffic it receives to the computers connected to it. Any traffic that goes in one port comes out of the other ports. As a result, all the computers receive the traffic, even if it is not for them. A switch is more intelligent than a hub. As a hub, a switch is the connection point for the computers and other devices in a network.
However, a switch is more efficient at passing along traffic. It records the addresses of the computers connected to it in a table.
When traffic comes through, the switch reads the destination address and sends that traffic to the appropriate computer rather than sending it to all the connected computers. If the destination address is not in the table, the switch sends the traffic to all the connected computers.
A router is the most intelligent of the three hardware devices. It is typically a small computing device designed specifically to understand, manipulate, and direct traffic. Routers include a user interface so that you can tell them where to direct the traffic.
The primary function of a traditional router is to connect two or more networks or network segments in a very large network and direct traffic between them. For instance, a business might use a router to manage the connection between its local network and the Internet. To distribute the traffic to the computers in the local network, the business could connect the router to a switch or hub. While traditional routers are still available, most small business and home office routers today combine the functionality of a router and the functionality of a switch or hub in a single unit.
These integrated routers often include additional software that lets businesses set up features such as network firewalls and virtual private networks. There are two main types of integrated routers: wired e.
Integrated routers are blurring the functional lines between routers, switches, and hubs. But they are not the only devices doing so. As switches become smarter, they are taking on some of the tasks that used to require a router. Even hubs are becoming more intelligent.

What's the Difference? Hub vs Switch vs Router
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. Switch: Switch is a network device which is used to enable the connection establishment and connection termination on the basis of need.
Learn how switches form a key networking building block that connect your devices to each other. Our world is facing an acceleration in the frequency, diversity, and impact of disruptions. Planning your network to help your organization respond to the unexpected is now more important than ever. Switches are key building blocks for any network. They connect multiple devices, such as computers, wireless access points , printers, and servers; on the same network within a building or campus. A switch enables connected devices to share information and talk to each other. An unmanaged network switch is designed so that you can simply plug them in and they work, no configuration required.
For example, my computer is plugged in to an A switch typically is multiples of the same type of connection. It is only possible because of networking devices that regulate data traffic over the whole network, providing connectivity and control. This leads to inefficiencies and wastage. Pretty much repeat signal on one end to another. Hubs are used on small netwo… The bridge being a data link layer device identifies theThis is all about the bridges now let us move to the Switches which are similar to the bridges. Whenever we talk about the switches we must specify the level at which the switch operates. A bridge is a networking device used to interconnect two or more networks together so that it looks like a single network.

In an Ethernet network, there are some networking devices that play their roles at various levels such as hubs, switches and routers. The functions of the three devices are all quite different from one another, even if sometimes they are all integrated into a single device. The following part will focus on the topic—hub vs switch vs router, aiming to clarify differences among them. A hub contains multiple ports.
Где оно? - не отставал Беккер. - Понятия не имею. - Парень хмыкнул.

- Фонтейн, как обычно, говорил спокойно и деловито. Глаза Джаббы по-прежнему выражали шок и растерянность, когда сзади раздался душераздирающий крик: - Джабба. Джабба. Это кричала Соши Кута, его технический ассистент, подбегая к платформе с длиннющей распечаткой в руке. У нее был такой вид, словно она только что увидела призрак. - Джабба! - Соши задыхалась. - Червь… я знаю, на что он запрограммирован! - Она сунула распечатку Джаббе.
Стратмор нахмурился: - В этом вся проблема. - Офицер полиции этого не знает. - Не имеет понятия. Рассказ канадца показался ему полным абсурдом, и он подумал, что старик еще не отошел от шока или страдает слабоумием. Тогда он посадил его на заднее сиденье своего мотоцикла, чтобы отвезти в гостиницу, где тот остановился.
Нет проблем. А как же проваливай и умри. ГЛАВА 36 Ручное отключение. Сьюзан отказывалась что-либо понимать. Она была абсолютно уверена, что не вводила такой команды - во всяком случае, намеренно.
Стратмор… он… - Мы знаем, - не дал ей договорить Бринкерхофф. - Он обошел систему Сквозь строй. - Да… и… - слова застревали у нее в горле. Он убил Дэвида. Бринкерхофф положил руку ей на плечо.
То была моль, севшая на одну из плат, в результате чего произошло короткое замыкание. Тогда-то виновников компьютерных сбоев и стали называть вирусами. У меня нет на это времени, - сказала себе Сьюзан. На поиски вируса может уйти несколько дней. Придется проверить тысячи строк программы, чтобы обнаружить крохотную ошибку, - это все равно что найти единственную опечатку в толстенной энциклопедии.
