Slotted Aloha is a random access protocol used in wireless communication systems to handle multiple users accessing the channel simultaneously. It divides time into slots and assigns each user a specific slot to transmit their data. The maximum efficiency of Slotted Aloha can be calculated by considering the efficiency of successful transmissions.

1. Understanding Slotted Aloha:
- Slotted Aloha divides time into equal slots.
- Each user can transmit their data in a specific slot.
- If multiple users try to transmit in the same slot, a collision occurs, and none of the transmissions are successful.
- The probability of a successful transmission depends on the number of users and the slot duration.

2. Efficiency Calculation:
- The efficiency of Slotted Aloha is defined as the ratio of successful transmissions to the total number of slots.
- Let's assume there are 'N' users and 'G' is the offered load (average number of transmissions per slot).
- The probability of a successful transmission is given by:
P_success = G * (1-G)^(N-1)

3. Maximum Efficiency at G = 1:
- To find the maximum efficiency, we need to maximize the value of P_success.
- When G = 1, the probability of a successful transmission becomes:
P_success = 1 * (1-1)^(N-1) = 0

- At G = 1, the probability of a successful transmission is zero because all slots are filled, causing collisions in every slot.
- Therefore, the maximum efficiency of Slotted Aloha at G = 1 is 0%.

4. Answer:
- The correct answer is option 'A' - 0%.

To summarize, the maximum efficiency of Slotted Aloha at G = 1 is 0%. At this point, all slots are filled, causing collisions in every slot and resulting in zero successful transmissions.

What is the maximum efficiency and stronger the slot of 1.23 log and desire the line appreciate and tall g = 12.33
