### Quiz Question: Medium Access Protocols for Ethernet Networks
**Question 4:**
Which of the following medium access protocols are used for Ethernet networks?
**Options:**
- **A.** CSMA/CA
- **B.** ALOHA
- **C.** CSMA/CD
- **D.** TDMA
---
**Explanation:**
Ethernet networks typically use the **CSMA/CD (Carrier Sense Multiple Access with Collision Detection)** protocol. This protocol helps manage how packets of data are transmitted in a shared network to avoid collisions and ensure smooth communication.
- **CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance)** is typically used in wireless networks like WiFi to avoid collisions.
- **ALOHA** is a simple communication scheme used in satellite and wireless data networks.
- **TDMA (Time Division Multiple Access)** divides the channel into time slots assigned to different streams of data, often used in cellular networks.
