### Networking Efficiency Question

**Problem Statement:**

200 nodes are connected to a 1,500-meter length of coaxial cable. Using a certain protocol, each node can transmit 50 frames per second, with each frame averaging 2,000 bits in length. The transmission rate at each node is 100 Mbps (where 1 Mbps = 1,000,000 bps). What is the efficiency of this protocol?

---

To determine the efficiency of the protocol described, follow these steps:

1. **Calculate the total bits transmitted by all nodes per second:**
   
   Each node transmits 50 frames/second, and each frame is 2,000 bits long.
   
   So, total bits per node per second = 50 frames/second * 2,000 bits/frame = 100,000 bits/second.

2. **Calculate the total bits transmitted by all 200 nodes per second:**
   
   Total bits per second for all nodes = 100,000 bits/second * 200 nodes = 20,000,000 bits/second = 20 Mbps.

3. **Find the transmission rate at each node:**
   
   The given transmission rate is 100 Mbps.

4. **Calculate the efficiency of the protocol:**
   
   Efficiency = (Total bits transmitted by all nodes per second) / (Transmission rate at each node * Number of nodes).
   
   Substituting in the values:
   Efficiency = 20 Mbps / (100 Mbps * 200) = 20 Mbps / 20,000 Mbps = 0.001 or 0.1%.

Therefore, the efficiency of the protocol is 0.1%.

This calculation illustrates how efficiently the protocol utilizes the available bandwidth on the network.
