HUB NETWORKING DEVICES

Yeh ek NETWORKING DEVICES hota hai jo LAN Network mai use kiya jata hai. HUB ka use apko kisi computer lab mai dekhne ko mil jayga. Jaise ek jagah par 10 computers hai. or veh sabhi HUB se connect hote hai .

Ethernet Wire ke through or ik dusre ke sath Communication kar rahe hote hai. HUB ka use karke agar ek computer kisi dusre computer ke sath file sharing jaise kaam karna chahta hai. Tab veh asani se kar sakte hai

HUB se connected sabhi computer ek dusre ke sath communicate kar sakte hai. Lekin agar HUB ka use kisi network mai kiya jata hai

Jab ek computer ko kisi dusre computer ke sath file transfer karni hoti hai. Tab HUB us file ko sabhi computers par bhej deta hai or jis computer ke liye file bheji jati hai. Veh computer use accept kar leta hai. Isme data packets mai source ka or destination ka IP Address hota hai.

Jis vajah se data apne destination tak pahuch jata hai. Yeh smart NETWORKING DEVICES nahi mana jata hai. HUB do types ke hote hai Active HUB or  Passive HUB. HUB OSI Model ki Physical layer par kaam karta hai

Active Hubs

Active Hubs humare signal ko regenerate or amplify karke signals ko age bhejte hai inme electricity ki jarurt hoti hai

Passive Hubs

Passive Hubs kisi tarah se signals ko regenerate ya amplify nahi karte hai. Yeh bas pahle se a rahe signals ko age forward karne ka kaam karte hai. Inko electricity ki jarurt nahi hoti hai

Intellegent Hub

Yeh Hub signals ko  regenerate nahi karte hai or amplify bhi nahi karte hai. Intellegent Hub ka use karke Monitor kiya jata hai. Baki ke sabhi Hubs or ek Hubs ke sabhi Ports ko administrator ke through configure kiya ja sakta hai. Or inhe managable hubs bhi kaha jata hai

SWITCH NETWORKING DEVICES

Yeh ek Networking device hota hai. Switch ka use HUB ki tarah hi kiya jata hai. Iska use karke kisi Computer lab mai sabhi computers ko ek dusre se communicate karvaya ja sakta hai.

Lekin yeh ek Smart NETWORKING DEVICE hota hai. Kyoki switch ke through jab ek computer se kisi dusre computer ke sath file share ki jati hai. Tab Switch Network se connected kisi dusre computer par file nahi bhejta hai. Veh usi computer par file bhejta hai jis computer ke liye file bheji jati hai.

Yeh data ko forward karne ke sath data ki filtering bhi karta hai. Switch ka use karke agar 10 computers ko connect kiya jata hai tab switch un sabhi computers ke IP Address ko save rakhta hai taki future mai jab communication karna hota hai. Tab veh IP Address ki help se destination computer ko dhund pate hai.

Jise CAM(content address memory) table kaha jata hai. switch ki speed  simultaneously hoti hai. Chaliye ise example ke through smjhte hai. Jaise maan lijiye ek Network mai 4 computer hai. a,b,c,d or agar computer a computer b ko data bhejta hai. Usi time agar computer b bhi computer a ko data bhejta hai tab dono taraf se data sharing ki speed same hoti hai.

Types Of Switch

Store and Forward

cut Through

fragment free

Adaptive switch

Store and Forward

Store and Forward Switch mai ek Buffer lagaya hota hai. Jab yeh frame ko receive karta hai tab yeh buffer mai store karta hai or error checking bhi karta hai.

Agar frame mai kisi tarah ki error ati hai tab yeh frame ko drop kar deta hai or forward nahi karta hai. Store and Forward slow hote hai. Lekin inke through kiya hua data transfer reliable hota hai.

Cut Through Switch

Cut Through switch mai frame ke hardware address ko hi dekha jata hai. Isme kisi tarah ki error checking nahi ki jati hai.

Cut through switch mai fastly data ko transfer kiya jata hai. Lekin iski koi guarantee nahi hoti hai ki data sahi se pahuchega ya nahi

Fragment free

Yeh store and Forward or Cut through switch ka combination hota hai. Kyoki is tarh ke switch mai data packets ko pahle 64 bytes ke data ki error checking ki jati hai.

Agar error ati hai tab data packets ko vahi drop kar diya jata hai. Agar nahi ati hai tab baki ke data ko check kiye bina hi forward kar diya jata hai.

Adaptive Switch

Adaptive Switch mai in teno tarah ke switches mai se jo sahi lagta hai. Unka automatically use ho jata hai. Jis tarah ke data ko bhejen ke liye jis tarah ki switching process better lagti hai uska automatic use ho jata hai.

Router Networking Device

Router ek NETWORKING DEVICE hota hai. Jaise ki naam se hi pata chalta hai route kisi do ya do se jada network ko route karna. Router ki help se ek network ko kisi dusre network ke sath connect kiya ja sakta hai.

Jaise maan lijiye ek network mai 5 computer hai or dusre network mai bhi 5 computer hai or ek network ka IP Address 10 ki series ka hai or dusre network ka IP Address 20 ki series ka hai. Aise mai dono network ko communication karne ke liye Router ki jarurt padti hai.

Router do alag alag tarah ke network ko apas mai Communication karvane ke liye use kiya jata hai. Aap is blog ko bhi kisi na kisi router ke through hi padh pa rahe hai. Router OSI Model ki Network layer par kaam karta hai.

Restrict Broadcast to the Network

Broadcast ka matlab ek data ko sabhi devices par send karna hota hai bina Broadcast ke communication karna bahut hi mushkil hota hai. Bahut tarah ke Protocols Broadcast ke through ik dusre se communicate karte hai.

Jaise AAP , RRP or dhcp etc Broadcast ko router ki help se puri tarah se khatam to nahi kiya ja sakta hai. Lekin kam kiya ja sakta hai

Chote Network mai Broadcast karne se jada Problem nahi ati hai. Lekin kisi bade network mai Broadcast hota hai. Agar tab data ko problem a sakti hai

Jada Broadcast hone par data loss hone jaise or speed kam hone jaisi Problems dekhne ko mil jati hai. Lekin do network mai router hota hai. Tab veh router ke through network ko chote chote parts mai bant diya jata hai.

Acts as a default gateway

Router as act default gateway bhi apna kaam karte hai. Jaise agar ek network mai kuch computers hai. Tab bina network ke veh ik dusre se communication kar sakte hai.

Agar unhe internet access karna hota hai tab bina router ke aisa nahi kiya ja sakta. Aise mai router default gateway apna kaam karta hai. Aise mai sabhi computers ko internet access karne ke liye gateway mai router ka IP Address configure karna hota hai.

Route Between Networks

Router do alag alag tarh ke networks ko apas mai communication karne ke liye help karta hai. Jaise network mai computers ka IP Address 10 ki series ka hai or use kisi dusre network se connect hona hota hai.

Yeh kaam router ki help se kiya jata hai. Router ki help se wired or wireless dono tarah ke connections se connected devices ko ik dusre se connect bhi karta hai

Learn and Advertise Loop free paths

Jab hum  internet ka use karte hai. Tab humare pass connections kisi ek router ke through nahi banta hai. bahut sare routers ko ek sath connect hote hai. Jinki help se hum internet par kuch bhi research kar pate hai.

Jaise hum agar browser mai google.com ko open karte hai tab google.com tak humara computer se connection bane ke liye bahut sare routers ka use hota hai.

Sabhi routers mai routing table configure hote hai. Jinki help se routers ik dusre se connect ho pate hai or user routers ki help se internet se connect ho pata hai

Bridge NETWORKING DEVICES

BRIDGE ek Networking Device hai. Jis trh router ka use karke do alag alag trh ke Network ko connect kiya jata hai. Aise hi Bridge ka use Sub network ko connect karne ke liye kiya jata hai.

Jaise ek computer lab 1st floor par hai or dusri computer lab 2nd floor par hai. Aise mai dono floor ki computer labs ko connect karne ke liye Bridge ka use kiya jata hai.

jaise maan lijiye ek traf 5 computer hai or dusri tarf bhi 5 computer hai. Dono ke bich mai Bridge ko lgaya jata hai. Aise mai agar no 2 computer ko agar no 7 computer ke sath communication karna hota hai.

NETWORKING DEVICES

Tabhi Bridge data ko dusri taraf bhejta hai. Lekin agar no 2 computer ko no 4 computer ke sath communication karna hota hai. Tab Bridge data ko dusri taraf nahi bhejta hai.

Bridge OSI Model ki data link layer par kaam karta hai. Yeh source or destination mac address ki help se data ko sahi jagah par bhejta hai

Modem NETWORKING DEVICES

Iska use aaj ke time mai bahut jgh kiya jata hai. Jab ghar mai internet lagvaya jata hai tab vaha par bhi MODEM ka use kiya jata hai. MODEM data ko Modulator or Demodulator karta hai.

Jaise agar data signals hai tab Modulator kaam karta hai. Agar data analog signal mai hai tab demodulator kaam karta hai. COMPUTERS data ko Digital Form mai smjhta hai

NETWORKING DEVICES

Cables ke through signals analog form mai ate hai. Modem mai Router , Switch  ke bhi features diye gye hote hai. Jis vjh se computers ko ethernet ke through modem se connect kiya ja sakta hai .   

Modem (ADSL) Asymmetric digital subscriber line technique ka use karta hai routing karne ke liye ADSL or Modem ki help se hum internet ko access kar sakte hai.

Repeater NETWORKING DEVICES

Repeater ek aisa Device hai jo signals ki strength ko bdhane ka kaam karta hai. Iski vjh se data ko dur tak pahuchaya ja sakta hai. Jaise agar signals kisi jgh kam ate hai.

Aise mai repeater ka use karke signal ki strength ko bdha diya jata hai. Repeater piche se arhe signals ko receive karke unhe retransmit karke age forward karta hai. Repeater ka use karne se data Loss bhi nahi hota hai.

Jaise do buildings hai or ek building mai signal ache se ate hai. Lekin dusri building tak signals nahi ate hai. Tab aise mai repeater ka use karke signal ki strength ko bdhaya ja sakta hai. Taki dusri building tak signals ache se phuch sake Analog repeaters signals ko amplify karke age forward karte hai. Jab ki Digital Repeaters signals ko pure karke regenerate karke hi signals ko age Forward karte hai.

The Conclusion

Main umeed karta hu ki apko NETWORKING DEVICES ke bare mai ache se para chal gaya hoga. Or sath hi NETWORKING DEVICES ke types ke bare mai bhi pata chal gya hoga.

NETWORKING DEVICES ke bina Communication  karne ka socha bhi nahi ja sakta hai. Hum puri tarah se NETWORKING DEVICES se ghire rehte hai/

Kyoki inka use hum daily kisi na kisi tarah se karte hai. Agar aapka NETWORKING DEVICES ya kisi bhi tarah ka koi question hai tab aap humse comment box mai puch sakte hai is post ko jarur share karen.
