Coaxial cable in computer network in hindi

Coaxial cable (co-axial cable) ek prakar ka transmission medium hai jo high-frequency signals, audio, video, aur data ko transmit karne ke liye istemal hota hai. Isme central conductor, insulation layer, shielding, aur outer protective covering se bana hota hai. Coaxial cables commonly television networks, cable TV, internet service providers, aur surveillance systems mein istemal hote hain.

Coaxial cable ka structure is tarah hota hai:

  1. Central Conductor: Coaxial cable ka central conductor ek solid copper wire ya copper-plated steel wire hota hai. Isme electrical signals ko transmit karne ke liye current flow hota hai.

  2. Insulation Layer: Central conductor ke aas-pass ek insulation layer hoti hai jo conductor ko outer shielding se separate rakhti hai. Is insulation layer ka role electrical isolation aur interference protection hota hai.

  3. Shielding: Insulation layer ke bahar ek metallic shielding layer hoti hai, jisse cable ko electromagnetic interference (EMI) se bachaya jata hai. Shielding typically braided copper wire mesh ya foil hoti hai.

  4. Outer Protective Covering: Metallic shielding layer ke upar ek outer protective covering hoti hai, jo cable ko physical damage, moisture, aur environmental factors se protect karti hai. Ye covering usually plastic, PVC (Polyvinyl Chloride), ya rubber material ki hoti hai.

Coaxial cable ke kuch important characteristics hain:

  1. Bandwidth: Coaxial cables high bandwidth support karte hain, jisse high-frequency signals aur data transmission possible hoti hai. Isliye, ye cable high-speed internet aur high-quality video transmission ke liye bhi istemal hote hain.

  2. Impedance: Coaxial cables ka characteristic impedance specific hota hai, jaise 50 ohms aur 75 ohms. Impedance matching important hota hai reliable signal transmission ke liye.

  3. Signal Loss: Coaxial cables mein signal loss (attenuation) frequency aur cable length par depend karti hai. Higher frequencies aur longer cable lengths par signal loss ki value badh sakti hai.

  4. Types: Coaxial cables different types aur categories mein aate hain, jaise RG-6, RG-11, aur RG-59. Ye categories cable ke construction, impedance, aur specific applications ke basis par differ karte hain.

Coaxial cables high-quality signal transmission aur interference protection provide karte hain. Iske through high-frequency signals, audio, video, aur data ko long distances tak transmit kiya ja sakta hai. Coaxial cables robustness, low signal loss, aur noise immunity ki wajah se television networks, cable TV distribution, broadband internet connectivity, aur CCTV surveillance systems mein widely istemal hote hain.
