Jab baat networking aati hai to ham kaise bhul sakate hain Network Hub ko ab sawal uthta hai kee kya aap janate hain ki Hub ya Network Hub Kya hai ? iska ek Asan sa jawab hai kee yeh ek bhot hi Basic networking device hoti hain. Iske istemaal se multiple computer ko dusre networking device ke sath joda jata hain. hubs aise common network infrastructure device hote hain iska istemaal Lan Connectivity ke liye hota hain, wahi Switchs ab Hubs Ko replace karne laga hain. Hubs Lans ke Central Connection point Ke hisab Se function Karta Hain.

Hubs ko designed kiya jata hain Twisted pair cabling ke sath kaam karne ke liye aur yeh sadharanroop se RJ45 Jack ka istemaal karte hain dusre devices ke sath jod ne ke liye Network device jaise kee ( Servers, Workstations, Printers, Scanners, etc) ko hub ke sath attached kiya jata hain. Individual network cable ke madhyam se, wahi hubs bahot se alag alag shapes main aate hain aur sath main iske alag alag ports hote hain aur in main apna koi routing table nhi hote hain jisse inhe ye nahi pata hota hain kee jab koi data aata hain tab inhe kis node ko bheja jaaye. Yeh sirf data ko multiple ports main broadcast karata hain Hubs OSI Data Model ke Layer-1 ( Physical Layer) main Operate hota hain.

Wahi Hubs ke ware me logo main bahot se doubts hote hain isliye aaj maine socha kee kyun na Hubs Kya hota hain ke ware main sab janakari aapke sath pradan kee jaaye jisse to aapko yeh pata chal sake kee yah networking device kaise kaam karata hain aur iske advantage or disadvantage Kya hote hain to phir chaliye suru karate hain………….

Hubs Kya Hain (What is Hubs in Hindi)

Hub ek aisa device hota hain jo kee ek network connection ko multiple computers me split karata hain yah ek distribution center ke jaisa hota hain. Jab ek computer information ke liye request karata hain kee kisi ek network se ya ek specific computer se, tab yeh us request ko send karata hain. Hub ko ek cable ke madhyam se, tab Hub us request ko receive karati hain aur use poore Network me transmit karati hain us network me moujood sabhi computer ko phir se yeh janana hota hain kee ye jo data broadcast hua hota hain yeh unke liye hain ya phir nahi….

Lakin yeh abhi Hubs bahot hi kam prachalan main hain aur inhe jyada advanced communication devices jaise kee Switched ya Routers ke dhyara replace kiya ja raha hain. Yeh Hub basically ek multiport repeater hota hain is Hub ka istemaal multiple wires ko jadne ke liye hota hain jo kee alag alag branches se aate hain example ke liye connector jiska istemaal Star topology me hota hain aur yeh alag alag stations ko jodne ke liye istemaal kiya jaata hain……..

Hubs data ko filters nahi kiya jaa sakata hain isliye data packets ko sabhi connected device ko bheja jaata hain. Dusre shbdon me kahe tab, sabhi hosts jo kee Hub ke sath jude hote hain unki collision Domain one (1) hoti hain. Inke alawa unki khud kee intelligence bhi nhi hoti Hain. Jisse ki wo Data packets ke liye best path dhudh sake jisse ant me inki wastage aur inefficiencies bhi……

Network Hub kya hain?

Network hub ek aisa networking device hota hain jo ki multiple peripherals se juda hota hain. Ek network main or unhe ek hi single segment ke jaise Kaam karne me madad karata hain. Wahi yeh Switch ya Router ke vipreet ye data ko broadcast karata hain sabhi connection ke across n kee unhe specific device ko route karata hain

Network Hub ki alag alag speeds bhi hote hain jinhe kee network data rate ya bandwidth kaha jata hain jaha pahle ke order network hubs keval 10 Mbps Speed pradan karate the. Wahi abhi ke hubs 100mbps tak ki speeds pradan karata hain. Abhi ke bade Networks me, ye jaruri hota hain ki ek dual speed network hub ka istemaal kiya jaata hai aur ye dono 10 ya 100 Mbps me aata hain jo ki computers aur printers ko connection points pradan karata hain isliye hub ki kharidari ke pahle is baat ka dhyan de kee aapke us network hub ke sath kitne equipment connect kiye jaege….

Network Hub ke Features Kya Hote Hain

Kya aapko pata hain ek big hub se adhiktam kitne computer jud sakate hain? Agar ham ek USB Hub kee baat Kare to ham isme ham 127 devices connect kar sakate hain aur network hub main 32. To chaliye ab janate hain Network Hub ke Features Kya hote hain.

  • Ye half duplex mode me operate hoti hain
  • Ye 4 see lekar 24 Port sizes me available hoti hain
  • Isme Host hi Responsible hote hain agar koi Collision detection aur retransmission of packets hota hain tab.
  • Inki mukhy roop se three type ke hote hain – Active hub , passive hub, Intelligent hub

Hub kaise kaam karata hain

Yadi ham sahi Mai ne main dekhe tab ek network hub jyada ek Variable Port Repeater hota hain aur n kee keval ek common Link hota hain. Cluster of Computers ke Liye iska Jo bahot hi common operation hota hain wo yeh kee ise jo bhi information prapt hoti hain. Unhe ye aage sabhi PC Terminals jo kee attached hote hain unhe ye forward kar deta hain ismain Jo ek big disadvantage hain wo yeh ki ismain data kee repetition hoti hain jisse kee unnecessary data traffic ko network main sent kiya jaata hai. Isliye isme data ko sent kiya jaata hain bulk main bina uske destination ko identify kiye hi….

Network hub kaise kaam karta hai

Wahi agar ham iski tulna kare Switchs se tab wo jyada efficient tarike se kaam karta hai Switchs Data traffic ke flow ko control karta hain ek organized tarike se, ek Switchs bahot hi intelligent device hota hain. Ye aasani se ye identify kar leta hain kee kise data send kiya jaye sahi data packets ka appropriate units main transfer karne se network bandwidth main badhotari hoti hain isliye ham kahe sakte hain ki hub ke jagah me Switch ka istemaal karne se network mai unnecessary data load nhi hota hain. Ye unnecessary data flow se wahi saman matra ki information ko sabhi units Tak bheja jaata hain chahe waha unki jarurat ho ya n ho……

Hub ka istemaal chhote networks mai jyada hota hain wahi Switch ka istemaal Large network hota hain ye network hubs aise device hote hain Jo kee OSI Model ke Layer one (physical Layer) me operate karte hain. Wahi Switches Layer 2 (Data Link Layer) me operate karte hai OSI Model ke. Aksar ek Switch aur ek hub ko combined Kar istemaal kiya jaata hai ek Switching hub ke hisab Se, aur ye sahi data packets ko sahi jagah tak pahuchane me madad karta hain…

Hubs ke Uses Kya hote hain?

In Network Hub ko Switchs ke jagah me istemaal kiya jaata sakata hain. Kyonki jyda expensive nahi hote hain saste hone ke sath sath bhot se kaam me hi istemaal kiye jaate hain…..

  1. Kuch special cases main hub ko network taps ke sthan me istemaal kiya jaata hai. Jisse kee protocol analyzer ka effective installation ho sake
  2. Network Hub bahot hi jyada efficient hota hain bahot hi bade traffic load ko receive karne ke Liye Jo kee cluster of Computers ke liye aata hain…
  3. Ye bahot hi asan hote hain istemaal karne ke liye wahi agar hame switch ka istemaal karna pada hub ke sthan par tab hame Switch Settings ko pahle configure karna hoga.
  4. Inhe istemaal kiya ja sakta hai ek Loop ko establish karne ke liye, jaha par ye jaroori ho kee end users ko ek connection pradan kiya jaye ek presentation hall me…
  5. Hubs ko network extension ke liye istemaal kiya ja sakta hai kyunki network hubs sabhi data packets ko aage repeat karte hain unhe jo bhi bheja jaaye…
  6. Wahi hubs ko jyada specifically small networks me jyda istemaal kiya jata hain….

At leastAt least muje umeed hai kee aapko meri yah article Network hub kya hain ( what is network hub in hindi) jaroor pasand aayi hogi meri hamesa yahi kosish rahti Hain kee hubs kaise kaam karta hai kee poori janakari ki jaaye jisse unhe kisi dusre Sites ya Internet par us article ke ware khoj ne kee jarurat nahi hain iske wajah se samay kee bachat bhi hogi aur ek hi jagah me unhe sabhi information bhi mil jayeaga.
