Ring Topology Simulator — Token Ring

Sab computers ek band ring (loop) mein juray hote hain, aur data hamesha ek hi direction (clockwise) mein safar karta hai. Is topology ki khaas baat Token hai: ek khaali "Free Token" hamesha ring mein ghoomta rehta hai. Koi bhi computer tab tak data nahi bhej sakta jab tak uske paas Token na aa jaye — isi wajah se Ring topology mein collision kabhi nahi hota (Bus topology ke bar-aks). Token milte hi woh use Data Frame mein badal deta hai, jo poori ring ka chakkar laga kar wapas sender tak aata hai, phir sender ise hata kar naya Free Token chhor deta hai.
