Difference Hub, Switch, Bridge, Repeater, and Router

Difference Hub, Switch, Bridge, Repeater, and Router

In studying the science of computer networks, we certainly have heard of the device Hub, a Switch, Repeater, Bridge, and the Router. Perhaps the laity about computer networks and new learning, wondering, what is the function of the device? It is what? How does it work? on the occasion of ali, I will explain the function of the device Hub, a Switch, Repeater, Bridge, and the Router.

1. The Hub

The hub serves as a place to receive data files from your computer and then continue to your computer or elsewhere on a network, the Hub is typically used on a topological star.

How it works: copy a package arriving subjected to one port to another port on the Hub. In addition, the Hub also serves to divide the bandwidth to each port, where when 1 computer used, it will get access to bandwidth available for maximum. If more than 1 computer is used, then the bandwidth will be divided to all existing computer.

2. Switch

Before the Switch, the Hub was the one who first used to connect multiple computers, but from the explanation above, we have seen the kekurang owned by the Hub, one of which is on performance. For that the Switch was made to conduct a transparent bridging as a liaison segmentation of many network with memforward based on MAC address Address.

How it works: the Switch has two basic architecture used i.e. Cut Through and Store and Forward, Cut Through Switch has advantages in terms of speed because when a package comes only switches focus to the destination address before being forwarded to the tujuanya segment. Store and Forward Switch while the opposite of Trough Cut Switch that receives and analyzes the entire contents of the package before forwarding it to the destination and to check a package requires time. The switch can also be used as a repeater or signal booster. Specifications 10/100mbps will allocate 10/100mbps full for all ports, so regardless of the number of computers connected, the user always has the full bandwidth. Because the switch offers the performance of transfers and better data access, some people prefer to use switches rather than hubs.

3. Repeater

A Repeater is a useful tool to strengthen the signal, receives the digital signal andstrengthen it to be forwarded again, and be in the distance data transmission. In general the task of the repeater receives signals from the LAN cable and radiates back into the LAN cable to the other.

Not only work on cable but repeaterjuga work on wireless.

How it works: Continue and amplify the signal, does not have the knowledge of thedestination address segingga delivery data are broadcast, only have one domaincolision segingga when one of the busy port then the other ports will have to wait.

4. Bridge

The bridge serves to connect two LANS are similar, so that it can have a single LAN which is much larger than a LAN configuration without a Bridge. Bridge can connect to the same or different networks such as Ethernet and Fast Ethernet. The bridge is also useful for linking two LANS that use the method of transmission of the baseband or broadband.

How it works: Bridge ethernet address mapping from any node or an existing point on each network segment and allow only the necessary data traffic crossing the bridge. When a Bridge receives a packet, the Bridge determines the source and the destination segment. If the segment

same time, the package will be refused and if the rest of the different packages will be forwarded to the destination segment, in order to prevent corrupted messages, so as not to spread out from one segment.

5. The Router

Router serves as a liaison between the network to forward data

from one network to another network through the routing process. The router can be used to connect the local network to the internet, one example is the Mikrotik Router in the settings of its configuration can serve as a bridge or a switch.

How it works: how it works similar to a router switch and bridge. It processes data and filtering routers divide the network into multiple subnets so that only processes that are shown for a particular IP address that can be run from one segment toanother segment. In a Hub, Switch, Bridge, and is a networking device, then the router is an internetworking device.
