The devices Hub Y Switch They are common among technicians who are dedicated to managing ethernet networks, as well as routers are something common that you have heard of since today all internet services use it to distribute the service in your home.
These devices compete in the market offering similar conditions of use, but the big question is What is the difference between Switch, Router and Hub?
We know that Hubs Y Switches are used to mount local networks, while Routers they are capable of doing that and much more. But don’t worry! Next, we will show you which is the best, naming its advantages and disadvantages.
What is a hub?
The role of the Hub is interconnect computers within a local network, transmitting data to the rest of the computers that are within said local network. Allowing to create local networks in which the computers are only kept connected to said network and not to others.
The internet connection in the Hub devices It is not allowed like sending data to other computers or devices, it only makes a copy of what a computer receives and sends it to the rest of the network.
Advantage
- Relatively inexpensive price.
- This device does not add no delay in network connections no internal messages.
- It is a simple device that allows computers to be easily interconnected.
Disadvantages
- The device allows us to send information to computers that are not interested since there is only one recipient of the information, but this device sends said information to all computers that are connected at the same time.
- The traffic generated by this device increases the chances of a collision. A collision is called the process that a computer performs when sending information to a computer simultaneously that is performing the same task.
- When the messages collide, a loss is made and it is necessary to return to send the information in the hope that another collision will not take place, this is very likely when we add many computers to a single local network.
What is a switch?
The switch They are devices that are also used for the creation of local networks, but the most notable difference that makes Switch better than Hub is that the data sent by the computer is sent directly to a destination computer without being distributed, that is, without sending the same information to the rest of the teams that are connected to the same local network, so its most common use is to configure it to share the Internet with more computers and establish an ethernet network.
Advantage
- Possibility of working in a network with a greater number of connected computers.
- Smoother experience that reduces errors in local networks.
- It works by MAC addresses and thus allows us to identify each team.
Disadvantages
- You get more users a high latency that becomes annoying if you use real-time services, such as Voice over IP or video conferencing.
What is a router?
This device is responsible for the task of forwarding data packets between several networks, which can be local or lan and an external one with WAN port used to connect to a ADSL or fiber optic network and from there supply internet.
Routers fulfill the functions that it offers us Switch Y Hub that allows us to carry out the same activities, but with the difference that it has no limits in local networks and that it also allows us to connect to external networks and configure it as a repeater to improve your wifi.
Advantage
- Configurable and easy to maintain such settings.
- Effective against the presence of intruders.
- It is not topologically limited.
Disadvantages
- It takes a great deal of time to install and configure, always depending on the topology of our network and the protocols used.
- They have a higher cost and are more complex.
- They have a slowness in the process of packages than in the rest of the devices.
