Media Access Method (MAAM) ek aisi set of rules aur protocols hai jo computer networks mein istemal hoti hai jisse devices shared communication medium par data access aur transmission ko control karte hain. MAAM yeh tay karta hai ki devices medium ke liye access ke liye kaise contend karenge aur unki transmissions ko kaise coordinate karenge taki collision avoid ho sake aur communication efficient aur reliable ho sake. Alag-alag network technologies mein MAAM ke liye alag-alag media access methods istemal kiye jate hain, jaise:

- Carrier Sense Multiple Access/Collision Detection (CSMA/CD): CSMA/CD ek media access method hai jise Ethernet technology mein istemal kiya jata hai. Is method mein, device apne data transmission se pahle carrier (communication medium) ko sense karta hai (carrier sense), yani check karta hai ki koi dusra device already medium ko istemal kar raha hai ya nahi. Agar medium khali hai, tab device data transmit karti hai. Lekin agar do ya multiple devices carrier ko sense karte hai aur unka transmission overlap hota hai (collision), toh un devices ko collision detect karna hota hai (collision detection). Iske baad devices wait karte hai aur fir se randomly retry karte hai apni transmissions ko bhejne ke liye.
- Carrier Sense Multiple Access/Collision Avoidance (CSMA/CA): CSMA/CA ek media access method hai jo wireless networks, jaise Wi-Fi, mein istemal kiya jata hai. Is method mein, device carrier ko sense karta hai (carrier sense) aur agar medium khali hai, tab device data transmit karta hai. Lekin collision avoid karne ke liye, device apne transmissions ke liye contention window ka istemal karta hai. Contention window ek time interval hota hai jisme device randomly wait karta hai aur apni transmission ka samay chunta hai. Isse collisions kam ho jate hai.
- Time Division Multiple Access (TDMA): TDMA ek media access method hai jo time-division multiplexing par adharit hota hai. Is method mein, time slots ka istemal kiya jata hai jisme har device apni transmissions ko bhejti hai. Har device ke liye specific time slot hota hai jisme woh apna data transmit karta hai. Is tarike se devices ko dedicated time slots milte hain aur collisions avoid ho jate hain.
- Frequency Division Multiple Access (FDMA): FDMA ek media access method hai jo frequency-division multiplexing par adharit hota hai. Is method mein, frequency bands ko alag-alag devices ke liye allocate kiya jata hai. Har device specific frequency band ko istemal karke apna data transmit karta hai. Isse devices alag-alag frequency bands par operate karte hain aur interference aur collisions avoid ho jate hain.
Yeh kuch common media access methods hain jo network technologies mein istemal hote hain. In methods ka istemal network efficiency, throughput, aur reliability ko ensure karne ke liye hota hai.
