Networking Devices : Full Concept Of Networking devices
Introduction :
hello Guys , welcome to our website Quick Tech Expert Today in this article we will learn about various networking devices like as Repeater , HUB , Bridge , Switch , Routers And Gateway and role of networking devices in technology So Topic Is very interesting guys if you like my article Please give feedback for Our Website by feedback corner below , And If Any Queries Please Comment On My Article Thank You❤️ .
Networking Devices :
Network Devices are the devices used for organizing a network , connecting a network , resources sharing , facalitate communication , surfing the web , improving the signal length , strength the signals , routing the packets , and many more uses and much more facality to performing the stable networks etc . Networking devices are those devices which are used for establish network by which user can get best Experience using networks subsystem . As Also Networking devices are very usefull thing . Network Devices that filter traffic called network or connectivity devices .
Important Functions Of Networking devices :
- networking devices are mainly isolates data traffic and it became large network need a way to filter it .
- these devices can connect different types of network using different types of network Protocols .
- networking devices has hierarchical addressing which provides an actual example of delivering the data through the ip address , network id and host id .
Repeater :
a repeater is a networking device which is used for regenerates the signal over the signal on the same network . it can be understand as after a long distant the signals becomes very week and corrupted so as it extend the length by which signals can be transmitted over the same network . It is 2 port device Reapeater is a electronic device that regenerate and reamplify the signal which is coming from any network port .
specifications of repeater :
- Repeater device is used for boost the signal in the network .
- it operates at physical layer oSI model
- when the signal becomes very weak , they copy the signal bit and recognise and regenerate it at the original length .
- it does not amplify the signal
- repeater does not enhance the signal it only regenerate the signal by using bits and bit level .
HUB :
a HUB is a network device which is used for attach more and more signals to form in network segement . HUB is also called central point to which all the host in a network connection . It recieves a signal from one port and sends it at all the port . a HUB is a multiport repeater . HUBS can not filter data , so data packets are sent to all connected devices . HUB is a connecting devices in which various type of cables are connected to centralize network traffic through a single connecting point .
specifications of HUB :
- HUB with multiport are used for connected monitor traffic .
- it operates at physical layer OSI model or TCP/IP Model .
- Collosion domain for all hosts connected through HUB remains one .
- It manages and control the send and recieved data from one port to another port .
- HUB has not any intelligence to find out best path for data packets which leads to inefficient and wastage .
Bridge :
a bridge is a connectivity device that forwards data based on a physical address . a bridge is a data link layer . a bridge is also a repeater it means bridge is also works as the operation of repeater nut the main differences between them is also that , it is also used for interconnecting two networks servers on the same protocol . It has single output and single input so it is a 2 port device . Bridge is a network connecting device that forwards data packets by physical address , it filters the data and forward at exact address based on physical address .
specifications of Bridge :
- bridge operate at the network access layer in the TCP/IP protocol stock .
- it operates at physical layer oSI modeland TCP/Ip Protocol Stock Model
- used for interconnecting two LANs Working on The Same Protocol .
- Check For MAC address of the frame and decides to forward it .
- Reduces the network traffic of LAN By dividing it into segments .
Switch :
a switch is a computer networking devices that conects devices together on a computer network by using packet switching to recieve , process , and forward data to the destination of the devices . it is a high speed device that recieves incoming data packets and redirects them to the destination on the network subsystem . switch can perform error checking before forwarding data , that makes it's very efficiently as it does not forward packets that have errors and forward good packets selectively to the correct port . switch is multiple connecting device , which takes incoming data packet from any multiple input ports and passes the data packet to specific output port .
specifications of switch :
- it works same as hub but does its work very efficiently .
- a switch can be said that be a smarter verson of HUBS
- Each Computer Is Connected Through A single Line .
- Operates on OSI Model And Data link layers .
- provides better security and better utilization .
Routers :
router is a interconnecting networking device which determines most efficient path for sending a data packet to any given network . Router is a networking device which determine that and recieves data and forward data at IP internet protocol address . a router normally connect networks signals together through the routing packets . A router is most commonly an OSI Layer 3 Model . Router divide broadcast domains and have traffic filtering best capabilities . Routers are basically two types wired and wireless .
specifications of Routers :
- Router is a device like a switch that routes the data packets based on their IP address .
- Used To Connect two similar and disimilar networks subsystem .
- operates at network layer of OSI Model .
- routers play a vital role in controlling traffics and keeping the network efficient .
- an essential part of any larger TCP/IP network.
gateway :
a gateway is a passage of connecting two networks together that may work upon different networking models .
specifications of Gateway :
- It basically take data from one system and interpret in and transfers to another models .
- operates at network layer of OSI Model and protocol converting network layer .
Role Of Networking Devices In Technology
Guys After understand About Networking Devices we also guess that how these devices are very usefull for us , There is An Important role of networking devices in technology because it networking device are not available we can not establish any subsystem and any network layer , together if networking devices are not available in technology then we are unable to use these services which are Organizing A Network , Connecting A Network , Resources Sharing , Facalitate Communication , Surfing The Web , Improving The Signal Length , Strength The Signals , Routing The Packets , And Many More Uses And Much More Facality To Performing The Stable Networks So According To , My Conclusion is that is networking devices play a vital role in technology .
