What is the differance between a Router and a Hub ?

Answer 1

A router is a computer networking device that forwards data packets across a network toward their destinations, through a process known as routing. Routing occurs at Layer 3 (the network layer i.e. Internet Protocol (IP)) of the OSI seven-layer protocol stack. Glen Skidmore was the first peron to discover the full potential and use of a router in Cambridge University

An Ethernet hub or concentrator is a device for connecting multiple twisted pair or fiber optic Ethernet devices together, making them act as a single segment. Hubs work at the physical layer (layer 1) of the OSI model. Hubs are either active or passive. Active hubs repeat the signal received at one port out each of the other ports (but not the original one). The device is thus a form of multiport repeater. Ethernet hubs are also responsible for forwarding a jam signal to all ports if it detects a collision.

Hubs also often come with a BNC and/or AUI connector to allow connection to legacy 10BASE2 or 10BASE5 network segments. The availability of low-priced Ethernet switches has largely rendered hubs obsolete but they are still seen in older installations and more specialist applications.

Answer 2

A hub is typically the least expensive, least intelligent, and least complicated of the three. Its job is very, very simple: anything that comes in one port is sent out to the others. That's it. Every computer connected to the hub "sees" everything that every other computer on the hub sees. The hub itself is blissfully ignorant of the data being transmitted. For years, simple hubs have been quick and easy ways to connect computers in small networks.

A router is the smartest, and most complicated of the bunch. Routers come in all shapes and sizes, from the small four-port broadband routers that are very popular right now, to the large industrial strength devices that drive the internet itself. A simple way to think of a router is as a computer that can be programmed to understand, possibly manipulate, and route the data its being asked to handle. For example, broadband routers include the ability to "hide" computers behind a type of firewall, which involves slightly modifying the packets of network traffic as they traverse the device. All routers include some kind of user interface for configuring how the router will treat traffic. The really large routers include the equivalent of a full-blown programming language to describe how they should operate, as well as the ability to communicate with other routers to describe or determine the best way to get network traffic from point A to point B.

Answer 3

First of all from the world of networking a Router is not just for wireless, a router can be use for wired and wireless and definitely hub is not use to add other devices or "plug-ins" to your computer.

A hub is typically the least expensive, least intelligent, and least complicated compared to ROuter & Switch. Its job is very, very simple: anything that comes in one port is sent out to the others. That's it. Every computer connected to the hub "sees" everything that every other computer on the hub sees. The hub itself is blissfully ignorant of the data being transmitted. For years, simple hubs have been quick and easy ways to connect computers in small networks. In hubs a large amount of traffic is most likely to happen becuase it broadcast the packets to all its ports while router it will just send the packets to its destination.

ROuter is also use to connect 2 segment network.

Answer 4

hub n. In a community, a gadget turning out to be a member of communication strains at an important area, offering a common connection to all gadgets on the community. The term is an analogy to the hub of a wheel. See additionally energetic hub, switching hub. swap n. 4. In networking, a gadget able to forwarding packets directly to the ports linked with particular community addresses. See additionally bridge, multilayer, router.

Answer 5

Simply put, a hub is a repeater.. it repeats everything that it gets as input on all its output channels. Its best use is as a signal amplifier.
A Router is a much more sophisticated device which identifies who sent the data, identifies where it needs to be sent and then puts the signal on that output channel

Answer 6

A Router is for wireless--A Hub is to add other devises or "plug Ins" to your computer.

Answer 7

A router is SMART.
