Why Switch Better?

In the hub there anything in the process of handling network traffic. Hubs simply repeat the incoming signal to all ports on the hub. It will be very different from the switch, the switch in each port also serves as a bridge. If a port is connected to a device then the principal of each device will be independent of other devices. Another difference is that the 10/100 Ethernet hub only works in half-duplex, this means a device can only send or receive data at any given time. Switch is able to work in full-duplex, which means able to receive and transmit data at the same time. For instance, there is a switch on its port installed some of the following devices: - Computer 1 - Computer 2 - 3 Computer - Printer - File Server - Uplink to the internet Another difference is that the 10/100 Ethernet hub only work halfduplex, This means a device can only send or receive data at any given time. Switch is able to work in full-duplex, which means able to receive and transmit data at the same time. In this case, Computer 1 can perform the print process (print) the document, while the Computer 2 can access the file server, and while it is also the Computer 3 can access to the Internet. This all can be done because the switch can intelligently forward traffic only to the particular data packet peripheral devices involved only. It is also called the relationship between devices that simultaneous and independent. So the conclusion in the switch there is a mechanism for filtering and forwarding to the network traffic passing through it. Switch Working at the data link layer (OSI Layer Read about the post) but has the advantage that each port has its own collision domain (Port has its own data path) Switch also adopts a mac address learning where he will have a central pernerjemah table have a list of translators for all ports. Switch also can create a VPN between the sender and receiver ports. This switch uses full duplex transmission which has a path between the receive and transmit data separately. in data processing switches can be classified into three types: 1. Store and Forward - the switch will forward the frame after the data is received in full 2. Cut-Through Switch Forward Frame without waiting to receive the complete frame 3. Fragment Free (Hybrid) represents a compromise of The second type of switch over Switch also reinforced by the technology VLAN (Virtual LAN) where he is able to logically segmenting a LAN network without having to comply with the physical location of equipment. Switch also can serve as Spanning Tree protocol is redundant if he considers that a path was busy so he (the switch) will choose the other path is not busy.
