Describe the relevance of the 7-layer OSI protocol stack and the TCP/IP protocol stack. Add a diagram that places the two stacks next to each other so they show how the two can be related to each other.

2. IP datagrams may arrive in a seemingly random order of chunks that the receiving IP entity must continuously collect until it can reconstruct the original datagram. If the receiving IP entity possesses a buffer that assembles the original datagram's data field, the buffer will collect chunks of data with "holes" between them that correspond to data not yet received. Describe an algorithm in pseudocode, prose, graphical, or any other representation to collect and reconstruct the original datagram's data field based on this concept. Describe a simple mechanism for the tracking, management, and manipulation of the "holes" between data chunks.
4. What features are provided by a User Datagram Protocol (UDP) that are not provided by an Internet protocol (IP)? Describe a scenario when a UDP should be used. Describe a scenario when a UDP should not be used.
6. Think about a situation where you must setup a remote office for an organization. Describe and justify the network topology you would use, including any infrastructure and services. Discuss the network protocols you would use throughout the implementation assuming a proprietary collaborative system, which includes file-sharing and video conferencing capabilities.
