Transmission Media and channels in network in hindi

Transmission Media: Transmission media ek physical medium hai jiska istemal kiya jata hai data transmission ke liye. Ye medium data ko ek jagah se dusre jagah tak transmit karne ka madhyam banata hai. Kuch pramukh transmission media hai:

  1. Twisted Pair Cable: Twisted pair cables ek common transmission medium hai jo copper wires ka istemal karta hai. Isme copper wires ko tightly twist kiya jata hai, jisse electromagnetic interference kam hoti hai. Twisted pair cables telephone lines, Ethernet networks, aur DSL (Digital Subscriber Line) connections mein istemal hote hain.

  2. Coaxial Cable: Coaxial cables ek central conductor aur uske charon taraf insulation aur shielding wale layers se bane hote hain. Ye cables broadband internet, cable TV, aur video surveillance systems mein istemal hote hain. Coaxial cables higher bandwidth aur better noise immunity provide karte hain twisted pair cables ke comparison mein.

  3. Optical Fiber: Optical fibers light signals ka istemal karte hain data transmission ke liye. Ye cables glass fibers se bane hote hain, jisme light signals ko total internal reflection ka upyog karke transmit kiya jata hai. Optical fibers high data transfer rates, long-distance transmission capabilities, aur strong immunity to electromagnetic interference provide karte hain. Isliye, ye cables long-distance communication networks, high-speed internet, aur telecommunication systems mein use hote hain.

  4. Wireless Transmission: Wireless transmission media electromagnetic waves ka istemal karti hai data transmit karne ke liye. Isme radio waves, microwaves, aur infrared light ka upyog hota hai. Wireless transmission media, jaise ki Wi-Fi, Bluetooth, satellite communication, aur cellular networks, mein data ko airwaves ke through transmit kiya jata hai.

Transmission Channels: Transmission channels, transmission media ke through data transmission ke liye specific paths provide karte hain. Ye channels data ko source se destination tak transmit karte hain. Kuch pramukh transmission channels hai:

  1. Point-to-Point: Point-to-point channel mein data transmission ek source se ek specific destination tak hoti hai. Isme direct connection establish kiya jata hai source aur destination ke beech.

  2. Broadcast: Broadcast channel mein data transmission ek source se multiple destinations tak hoti hai. Isme source ek sath multiple receivers ko data transmit karta hai.

  3. Multipoint: Multipoint channel mein data transmission multiple sources se multiple destinations tak hoti hai. Isme multiple sources aur receivers ko ek common transmission medium ka istemal kiya jata hai.

  4. Simplex, Half-Duplex, aur Full-Duplex Channels: Jaisa ki pehle discuss kiya gaya, ye channels specific communication modes (simplex, half-duplex, aur full-duplex) ko support karte hain, jisse data transmit kiya ja sakta hai.

Transmission media aur channels, data transmission ke liye crucial elements hai. Transmission media physical medium provide karte hain data ko transmit karne ke liye, jabki channels specific paths create karte hain jiske through data transmit hota hai. Iske through, communication systems information exchange kar sakte hain.
