1. Multiple choice questions:

• a. Which layer is the Address Resolution Protocol in?
• i. Layer 2, the Internet Layer
• b. Which layer is the User Datagram Protocol in?
• iv. Layer 3, the Transport Layer
• c. Which layer includes network mediums such as Ethernet?
• iv. Layer 1, the Network Interface Layer

2. The TCP/IP model provides a framework including a set of communication protocols for the internet and computer networks. These protocols specify how data is transferred from one system to another. This includes how data should be packetized, addressed, transmitted, routed, and received, into 4 layers of abstraction. It enables easier worldwide networking communication.

3. Some differences between the TCP/IP Model and the OSI Model include: that the TCP/IP Model has 4 layers and the OSI Model has 7 layers, the OSI model is not protocol dependent, and the OSI Transport layer guarantees delivery of packets whereas the TCP/IP Transport layer doesn't. The OSI Model is used to help you understand how your network operates whereas the TCP/IP Model is used as a standard governed by the IETF.
