Star Topology Simulator

Is topology mein har device seedha ek central Hub ya Switch se apni alag cable ke zariye connect hota hai — bilkul ek sitaray ki kirnon ki tarah. Agar center mein Hub ho to wo ek "dumb" device hai: aane wala packet har connected device tak broadcast kar deta hai, aur sirf sahi receiver hi use accept karta hai, baqi sab discard kar dete hain. Agar center mein Switch ho to wo "smart" hai: apni address table dekh kar packet seedha sirf sahi receiver ki port par bhejta hai. Sabse bari khoobi: agar kisi ek device ki cable kat jaye to sirf wahi device disconnect hoti hai, baqi network chalti rehti hai — lekin agar Hub/Switch khud fail ho jaye to puri network down ho jati hai (single point of failure).
