Switch versus Hub
At present, a lot of people usually do not understand between a hub and a switch. They are the network hardware and have a nearly same look but their functions are not the same. In this article, I will compare and contrast their working and their functions. So, I like to use the switch more than the hub because it has many reasons that the switch has an advantage over the hub.
The first is the hub. It is a type of the network hardware used for connecting between a computer and the other computers. So, it is a central transfer data in a computer network. The hubs are not expensive and are not intelligent so that hub’s job is simple and it cannot manage network system very well.
The other is the switch. It is a type of the network hardware that is used for connecting between the computer and the other computers just like the hub but it has more functions to manage the network systems so it has the high cost. The example functions of switches, they can set up a VLAN to divide the group of network systems and set a bandwidth rate for each port to transfer data. Moreover, the switch can connect with other switches and routers for extending your network system. So that network system is called internetwork system.
While they are the network hardware but they have some similarities and some differences. For their similarities, they are the central transfer data in the computer network systems and they usually have many ports from four ports to twenty-four ports to connect with the computer by using RJ 45 lines by one port per one computer. For their differences, the hub’s working; they are very simply that is all data that comes in one port is sent out to the other ports. For instance, if we have 4 ports for hub, the data comes from the first port and it would send to second port for terminal but the computer on third and fourth port can see that data and can access it as same as computer in second port. This is a weakness for hubs. The working of switches, they do not essentially what the hubs do but they have more efficiently than the hubs. They are paying attention to a traffic that data comes from them. The switches can learn where particular addresses. For example, if the switch sees the data from computer on the first port, it knows that computer is connected to first port by using MAC address and only the traffic to that computer needs to send to the first port and do not any of the other ports. A result of using the switch over the hub is the most network traffic systems which only go where they need to rather than to every ports that as same as the hub. So, the switch can make the network significantly faster.
In conclusion, there are many reasons that the switches are better than the hubs. Even though, the switches are more expensive than the hubs but they have better efficiency. So, it is worth to use because they are very good for manage your network systems.
