क्या आप Network के बारे में जानते है. Network काम कैसे करता है और Network के Type क्या है. Network में Use होने वाली डिवाइस क्या है. LAN, MAN, WAN क्या है. Friends Aaj ki Iss post me Hum Apko Network or uske Type ke baare me batayenge.

What is Network|नेटवर्क क्या है?

Jab do ya usse Adhik device ko aapas me kisi source ke jariye connect kiya jata hai. Wo ek Network hota hai. Network ka ye source wire ya Wireless ho sakta hai. jiske through ek device se dusre device par Data Share kiya jata hai. Network agar wire based hai tab connecting ke liye Twisted Pair Cable, Coaxial Cable & Fiber Optics Cable ka use hota hai. Agar Networking source Wireless hai tab ye work Radio wave, Bluetooth, infrared, Satellite ke through hota hai.

Friends Computing Network ek ya Usse Adhik Device ka group hai. Jo bahut saare component jaise Computers, Server, Mainframe, Network device se connect hai Jisse hum ek group kah sakte hain. Jiska Use Data sharing ke liye kiya jata hai. Friends Aab Aasan sabdo me Aaj Har ek Computer & Mobile User Internet ka Use karta hai Jo ek worldwide Network hai. Jahan par Millions User ek dusre se connect rahte hai or Data Sharing jaise (Images, File, Audio, Video, Document etc. karte hai. Samjhate hain ek example ke jariye.

Example:- Friends hum Internet Cafe ka example le sakte hai. Kyoki Internet Cafe ke baare me maximum log jante hi honge. Aapne dekha hi hoga ke Internet Cafe par bahut sare computer hai. Wo device switch ya router ke jariye Server se connect rahte hai. Or printer bhi connect rahta hai. tab ye ek network hua. Ab baat karte hain ye kaise kaam karta hai. Friends user kisi bhi Computer par Internet ya koi bhi work kar rha hai tab wo kuch Important data ka Print dena chahata hai. Tab wo apni command se print de sakta hai us printer par jo Internet Cafe ke Network se connect hai.

A Brief History of Network|नेटवर्क का एक संक्षिप्त इतिहास

Friends Agar Network ki History ki baat kare too Iska Develop Computer ke develop ke sath hi start hua. Starting me America ke defense department ke liye 1969 me ARPANET ke naam se ek Network develop kiya. Jisko starting me 4 computer se Connect kiya gya tha. ARPANET (Advanced Research Project Agency Network) ko dheere dheere develop kiya or Isme Bahut saare Improvement kiye jiske karan Aaj ye Network World ka Sabase Bada Network Ban chuka hai. Jisko Hum Internet ke naam se jante hai.

Devices of Network|नेटवर्क के उपकरण?

Network ki devices ke baare me Baat karte hai kyoki computer ke sath sath Inn Device ke Bina Network complete nhi hai. In Device ke Hone se hi aap ek Computer Network creat kar payenge. Ye hain Network devices-

  • Hub:- Hub ek Networking device hai jo Physical Layer par work karti hai. ye Multiple Ethernet ke through Device ko Apas me connect karti hai jiske through data ka transfer kiya ja sake. Isme Multiport hone ke karan isko hum Multiport Repeater bhi kahte hai. Hub two types ki hoti hai. Active Hubs & Passive Hubs.
  • Switch:- Switch bhi Hub ki tarah hota hai jo Physical Layer par work karta hai. Switch ka use Local Area Networking ke liye kiya jata hai. Ye Hub ke muqable Fast hota hai. Isliye ye Hub se Jyada Intelligence hota hai.
  • Modem:- Modem ke baare me Apne suna hi hoga or Maximum user iska use bhi karte hai. Iska Use Internet ke liye kiya jata hai. Jiske thorugh hum Internet se Data Access karte hai.

  • Router:- Router ek electronics Device hai jiska use Computer ko network or Internet se connect karne ke liy kiya jata hai. Aajkal Market me bahut saare HiSpeed Router ate hain jisko through Data Packet ko Fastly Transfer kiya jata hai. Router Network Layer par work karta hai. Router two types ke hote hai- Broadband Router & Wireless Router.
  • Bridge:- Iss Electronic device ka use Alag Alag Network ko connect karne ke liye kiya jata hai. Example ke liye jaise Kisi Computer center par 2 Lab hai. Ek ground Floor par or Ek First Floor par tab Dono Lab ke Network ko connect karne ke liye Bridge ka use kiya jata hai.
  • Repeater:- Repeater ek network device hai jiska use Network Signal Strength ko badane ke liye kiya jata hai. Jab kisi Network ko kafi dur tak le jate hai tab signal week hone ki problem ko door karne ke liye Repeater ka use kiya jata hai.

Types of Network |नेटवर्क के प्रकार-

Computer Networking me Network ko 3 types me divid kiya gaya hai. Basically computer ke 3 Network ye hai-

  • LAN (Local Area Network)
  • MAN (Metropolitan Area Network)
  • WAN (Wide Area Network)

Local Area Network ( LAN )-

Local Area Network ka use 2 ya 2 se jayada computer ko connect karne ke liye kiya jata hai. Ye Local Area par work karne wala Network hai. Jaise Home, Office, Building. LAN ko wire ya Wireless connection ke jariye connect kar sakte hai. Basically Local Area Network ka use ek office me file document, Printer sharing ke liye kiya jata hai.

  • Ye Network local area (Office, Home, Building) tak hi simit hai.
  • Local Area Network ko Ashaani se Creat kiya ja sakta hai.
  • Iss Network ki data Transmission speed high hoti hai.
  • Local Area Network par Data Safe rahta hai.
  • Iss Network ki Ownership Private hai.

Metropolitan Area Network ( MAN )-

Metropolitan Area Network ko hum kah sakte hai ki wo Network ka jiska use Ek City ko dusre City ke liye kiya jata hai. Jisse hum Metropolitan Area Network Kahte hai. Ye High-Speed wala Network hai. Iss Network se 2 ya 2 se Adhik Local Area Network Connect rahte hai. Jo Router Switch & Hub ke jariye connect hota hai. Iss Type ke Network ko Metropolitan Area Network kahte hain.

  • Metropolitan Area Network ki speed moderate hoti hai.
  • Yahan par LAN se jyada kharcha ata hai.
  • Metropolitan Area Network city tak hi simit hai.
  • Iss Network ki Ownership Public ya Private ho sakti hai.

Wide Area Network ( WAN )-

Ye Netwrok Kafi bada hota hai ye ek Building se lekar city or city se lekar world ke computer ko Connect karta hai. Iska Data Rate Kam hota hai. Kyoki ye jyada distence ko cover karta hai. Internet Wide Area Network ka Sabse Achcha Example hai. Ye Network 2 types ke hote hai. Jo Wide Area Network service ko provide karata hai. Usse Network Service Provider kaha jata hai. Ye LAN & MAN se kafi Costly hota hai.

  • Globel WAN
  • Enterprise WAN

Friends Kuch Wide Area Network hain jo iss prakar hai jaise Public Packet Network, Banking Networks, Railway Reservation Network, Airline Reservation Network & Military Networks etc.

Other Type of Network |अन्य प्रकार का नेटवर्क

Ye the main Network jinke baare me humne apko upar bataya. Ab baat karte hain Kuch Aise Network ki LAN or WAN ki through develop kiye gaye hain.

  • Personal Area Network ( PAN )
  • Wireless Local Area Network ( WLAN )
  • Campus Area Network ( CAN )
  • Storage Area Network ( SAN )
  • Enterprises Area Network ( EAP )
  • Virtual Private Network ( VPN )

Frineds Aaj ki Iss post me humne Apko Networks or uske Types ke baare me details me bataya umeed hai apko ye Post Achchi lagi hogi. Agar Apko ye Post achchi lagi tab aap humari post ko apne friends ko share kar sakte hai. Kuch new Technical Updates ke liye bane rhe On Online Tech Updates. Thanks For Reading……
