Technology in terms you understand.
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.
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.

Bridge- -Bridge is a layer 2 device which means it can learn and understand physical address to send data. Switch- A switch is a layer 2 device. 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.

Tutorial of Differences between Hub, Bridge, Switch and Router
Institutions — including, companies, universities and high schools — typically consist of many departments, with each department having and managing its own Ethernet LAN. Naturally, an institution will want its departments to interconnect their departmental LAN segments. In this section, we consider a number of different approaches in which LANs can be connected together. We'll cover three approaches, hubs, bridges, and switches in the following subsections. All three of these approaches are in widespread use today. The simplest way to interconnect LANs is to use a hub. A hub is a simple device that takes an input i.
A network switch also called switching hub , bridging hub , and, by the IEEE , MAC bridge  is networking hardware that connects devices on a computer network by using packet switching to receive and forward data to the destination device. A network switch is a multiport network bridge that uses MAC addresses to forward data at the data link layer layer 2 of the OSI model. Some switches can also forward data at the network layer layer 3 by additionally incorporating routing functionality. Such switches are commonly known as layer-3 switches or multilayer switches. Switches for Ethernet are the most common form of network switch.

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. Collisions remain an issue as well, so hubs do not help improve the performance of the network.

Repeater — A repeater operates at the physical layer. Its job is to regenerate the signal over the same network before the signal becomes too weak or corrupted so as to extend the length to which the signal can be transmitted over the same network. An important point to be noted about repeaters is that they do not amplify the signal. When the signal becomes weak, they copy the signal bit by bit and regenerate it at the original strength.

Беккер оглянулся и, увидев, как Халохот бежит по залу аэропорта с пистолетом в руке, бросил взгляд на свою стоящую на тротуаре веспу. Я погиб. Халохот вырвался из вращающейся двери в тот момент, когда Беккер попытался завести мотоцикл. Убийца улыбнулся и начал поднимать пистолет.
Ему казалось, что с него сорваны все внешние покровы. Не было ни страха, ни ощущения своей значимости - исчезло. Он остался нагим - лишь плоть и кости перед лицом Господа.
Отпусти. - Чтобы вы меня убили. - Я не собираюсь тебя убивать.
Очень хорошенькие? - повторил он с нарочитым немецким акцентом. - Рыженькие. - Да, а как зовут вашего брата.
Может быть, американка? - предположил. - Не думаю, - сказала Росио. - На ней была майка с британским флагом. Беккер рассеянно кивнул: - Хорошо. Бело-красно-синие волосы, майка, серьга с черепом в ухе.
Беккер поморщился. - Предпочитаю вид спорта, в котором я могу выиграть. - Победа любой ценой? - улыбнулась Сьюзан. Защитник Джорджтауна перехватил опасную передачу, и по трибунам пронесся одобрительный гул.
