WHAT IS THE DIFFERENCE BETWEEN HUB, SWITCH AND, ROUTER ?

NETWORK COMMUNICATION DEVICES HUB, SWITCH AND ROUTER

•  Network basics required devices to provide connectivity and functionally. learning this network devices and how they operate our essential in setting up your own network. routers hubs and switches are network device terms that tend to be used interchangeably.
• The functions of the three devices of quite different from one another even though at times they are all integrated into a single device.                                                              
• Each device serves as a central connection for all of your network equipment and handles a data type known as frames a frame carries your data when a frame is received it is amplified and then transmitted onto the port of the destination pc the big difference between frames is in the method in which frames are being delivered.

                             WHAT IS HUB, SWITCH AND ROUTER?

                                    

   WHAT IS A HUB?

 a hub is a simple device that directs data packets to all devices connected to it. Basically I have does nothing except provide a pathway for the electrical signals and regenerate signal before it forwards it to all connected devices.

A message is forwarded along or broadcast to all of the hub's ports. It doesn't matter if the message is only for one port. The hub has no way of determining which port a message should be delivered to. Passing it along to each port guarantees that it reaches its proper destination. These add a lot of traffic to the network, which might lead to slow network response times.

It's 10 or 100 mbps have must share its bond with rich data transfer rate with each and every one of its ports. so when only one pc is broadcasting it will have access to the maximum available bandwidth.b however if multiple pieces are broadcasting that bandwidth will need to be divided among all of those systems which will degrade performance.

                                                                                     WHAT IS A SWITCH?

It is a similar to hubs, switches are the connectivity point of a wired network. Devicesare connected via twisted pair cabling one cable for each device. The difference between the two is on how the devices deal with the data that they receive. If a hub forwards the data it receives to all parts on the device as which forwards the data it receives only to the port that connects to the destination device. 

A switch keeps a record of the mac addresses or the   unique identity of the client devices connected to it. With this information stored in a switch it can identify which system is sitting on which port. Thus, when a message is received it knows exactly which port to send it the different from a hub, 10 or 100 mbps is which will allocate a full 10 or 100 mbps to each of its ports so it does not matter how many pieces transmitting users will always have access to the maximum amount of bandwidth. This is why switch is most considered to be much better choice than a hub. The network result of this measures is that switches can offer significant performance improvements over hub base networks particularly when network use is high.

                   WHAT IS A ROUTER?

Router are completely different devices. If a hub or switch is concerned with transmitting frames, the job of a router, as its name implies, is to route pockets to other networks until that packet ultimately reaches its destination. It can transmit through wired and wireless network. A router is typically connected to at least two networks commonly two local area networks or wide area networks or a LAN and its network internet the service providers network. 

Routers have a WAN port that connects to an internet connection provided by your Internet Service, Provider, the integrated switch allows users to easily create a LAN. This allows all the PCs on the land to have access to the internet windows file, and printer sharing services. Routers might have a single WAN port and a single LAN port and are designed to connect an existing LAN hub or switch to a WAN.  Switches and hubs can be connected to a router with multiple Pc ports to expand a LAN. When a router receives a packet of data it reads the header of the pocket to determine the destination address. Once it has determined the address it looks in its routing table to determine whether it knows how to reach the destination; does it forwards the pocket to the next hop on the route. the next hop might be the final destination or it might be another router. 

WHAT IS THE DIFFERENCE BETWEEN

 HUB, SWITCH, AND ROUTER? 

  

- The difference between the three main network communication devices a hub glues together a wired network segment.
- A switch can connect multiple wired segments more efficiently while a router can do those functions, plus route pockets between multiple LANs and/or so much more.
- Hubs simply broadcast data to all connected devices.
- Switches intelligently forward data packets to specific devices based on their MAC addresses.
- Routers forward data packets between different networks based on their IP addresses and make decisions about the best path for routing traffic.
