Main difference between hub and router

For someone who wants to know about hub and router, he can get quick clarification on that matter:

• The function of the hub is to link all the workstations and computers in to a network.

• Two separate and distinct networks are linked together by the help of router.

As compare to three layers of routers, one layer of hub generally operate in open system interconnection reference model.

A person who possesses a normal back ground with the workings of an OSI reference model, the above explanation is sufficient for him to understand about the hub and router. But this explanation raise more questions when it comes with the person like me i.e. Danish muzaffar who has average knowledge to intricate the world of networking. One can easily get confused devoid of networking knowledge about the difference between a hub and a router.

Computer networking:

A person wants to use the cable and wireless to physically connect the two links of computers together. You can consider it as the most basic form of networking. So if a person wants to connect more than two computers and a few peripherals, will he is opted for buying network cards for every workstation? The answer is simply no. you just need a device which receive the signal that are transmitted from one computer unit to other few machines linked with in the network.

Hub:

There is one tool which can easily answer one's networking.

• A multi porter repeater through which signals travel and conveyed into each and every port simultaneously.

• This is what the main working of the hub, forwarding electric signals to from one port to another port.

• Send a simple packet over a cabled link to a hub; it will be simply transmitted to all other ports.

• Hub doesn't distinguish electric signals.

This device is affordable and easy to use.

Why in need of routers:

Unfortunately networking is not as simple as it looks link all computers using several hubs. Now a day there is a fundamental scheme that is being arranged into networks.

A basic principle:

• At a given time a single machine transfer the data when linked to a network.

So from this, electrical signals flow in a single cable that one cannot have.

Let's imagine the conversation between two people at the exact moment. But at that time no one will understand any information disseminated. In grander and more serious scale, this applies in the field of networking. The consequence rooted is the sequence of collision and corruption of packets by using a hub from a synchronized transmission. But to be fair the computer will inherently back off and halt when they send the file at the same time for transferring of data. This process is unbearable at the big scale of network. How ever at this age hub is now where in the picture because a network received the biggest amount of traffic and it is not possible for the hub to control.

Router:

It is a type of computer which is bearing a couple of network cards, enabling and connecting the two networks to send and share data. It also bounces off the coming unsolicited transmissions. A router is needed, physically and logically to split the networks.

• For detecting a remote network path, a router is needed.

• A routing table is constructed in the internal memory of router where are all the links of networks are housed.

I hope that the information provided above will help you in future and you will surely get a lot of benefits from it.
