Question
**Question:** Which of the following medium access protocol are used for Ethernet network? **Options:** A. ALOHA B. CSMA/CA C. TDMA D. CSMA/CD **Explanation:** Ethernet networks commonly utilize the Carrier Sense Multiple Access with Collision Detection (CSMA/CD) protocol. This protocol helps manage data transmission and avoid collisions in a wired network environment. - **ALOHA:** An early networking protocol used in wireless communications, not typically used in Ethernet networks. - **CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance):** Mostly used in wireless networks, such as Wi-Fi. - **TDMA (Time Division Multiple Access):** A channel access method for shared-medium networks, often used in cellular networks. - **CSMA/CD (Carrier Sense Multiple Access with Collision Detection):** Used in Ethernet networks to manage data packet transmission and avoid collisions. The correct answer is **D. CSMA/CD**.

### Networking Protocols Quiz #### Question 1: The protocol used when we translate a local IP address into a global IP address is: - **A. DNS** - **B. IP** - **C. ARP** - **D. NAT** For more detailed explanations on each option: - **DNS (Domain Name System):** Translates human-readable domain names to IP addresses. - **IP (Internet Protocol):** Responsible for addressing and routing packets of data so they can travel across networks and arrive at the correct destination. - **ARP (Address Resolution Protocol):** Maps IP network addresses to the hardware (MAC) addresses used by a data link protocol. - **NAT (Network Address Translation):** Used to remap one IP address space into another by modifying network address information in the IP header of packets while they are in transit. **Correct Answer:** D. NAT This information is essential for understanding how different protocols operate in network communication and their specific roles.
