Question: Why Switch Is Called An Intelligent Hub?

What is an intelligent switch?

An intelligent switch is a high-level storage area network (SAN) routing switch that provides features such as storage virtualization, quality of service (QoS), remote mirroring, data sharing, protocol conversion, and advanced security..

Can a router act as a switch?

By simply running an Ethernet cable between your old router to your current one (run a wire from one of the available LAN ports on your active router to the WAN-in LAN ports on the old router), you can repurpose it as a network hub/switch.

What is the purpose of a hub?

A hub, also called a network hub, is a common connection point for devices in a network. Hubs are devices commonly used to connect segments of a LAN. The hub contains multiple ports. 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.

What is the purpose of network switch?

Multiple data cables are plugged into a switch to enable communication between different networked devices. Switches manage the flow of data across a network by transmitting a received network packet only to the one or more devices for which the packet is intended.

What is the difference between switch hub and router?

Unlike an Ethernet hub or switch that is concerned with transmitting frames, a router is to route packets to other networks until that packet ultimately reaches its destination….Hub vs Switch vs Router.templatePortHub4/12 portsSwitchmulti-port, usually between 4 and 48Router2/4/5/8 ports9 more columns

Why switch is called more intelligent than hub?

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.

Which is called an intelligent hub?

intelligent hub – Computer Definition A network device that performs a variety of processing functions, including network management, bridging, routing and switching. Contrast with passive hub and active hub. See hub. Intelligent Hub.

Should I use a hub or switch?

Switch is more efficient than the hub. A switch can join multiple computers within one LAN, and a hub just connects multiple Ethernet devices together as a single segment. Switch is smarter than hub to determine the target of the forwarding data.

What is difference between router and bridge?

Router and Bridge are both network connecting devices. Router works at network layer and is responsibe to find the shortest path for a packet whereas Bridge connects various devices in a network. Router connects devices across multiple networks.

Why Switch is an intelligent device?

Switches operate on hardware addresses to transfer data across devices connected to them. The reason switches are known as intelligent hubs is because they build address table in hardware to keep track of different hardware addresses and the port to which each hardware address is associated.

What is more secure a hub or a switch?

Why are switches more secure than hubs? Switches don’t require port mirroring for a network analyst to monitor traffic. … Switches will transmit data only to specific network devices, rather than broadcasting the same data to all of the devices in a network.

Are hubs still used today?

The purpose of a hub is to form a single network segment on which all devices can communicate directly with each other. Until the early 2000s, Ethernet hubs were widely used for home networking due to their simplicity and low cost. While broadband routers have replaced them in homes, hubs still serve a useful purpose.

What is the difference between hub switch router and bridge?

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.

Why is hub not intelligent?

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. … As a result, all the computers receive the traffic, even if it is not for them. For that reason, they have been rendered obsolete by switches.

What are two main differences between a hub and a switch?

A Hub is a networking device that allows you to connect multiple PCs to a single network, whereas a Switch connects various devices together on a single computer network. A Hub operates on the physical layer, whereas Switch operates on the data link layer.

Which one has more overhead a switch or a router?

A router has more overhead than a switch because of the following reasons: A router operates on three layers i.e. the physical layer, the data link layer and the network layer, whereas a switch operates on two layers, the physical layer and the data link layer.

What is the use of repeater?

In telecommunications, a repeater is an electronic device that receives a signal and retransmits it. Repeaters are used to extend transmissions so that the signal can cover longer distances or be received on the other side of an obstruction.

What is a disadvantage of a computer network?

Purchasing the network cabling and file servers can be expensive. Managing a large network is complicated, requires training and a network manager usually needs to be employed. … Viruses can spread to other computers throughout a computer network. There is a danger of hacking , particularly with wide area networks.
