This assignment delves into network protocols, focusing on the OSI model, TCP/IP, and Address Resolution Protocol (ARP). It explains the OSI model's layered approach to network communication, contrasting it with TCP/IP's horizontal structure. The role of ARP in mapping IP addresses to hardware addresses is detailed, along with the function of ARP caches. A significant portion of the assignment is dedicated to network design, discussing the importance of a well-planned network infrastructure and the selection of appropriate network devices like computers, routers, hubs, and switches. It addresses IP addressing, subnetting, and the impact of exceeding host limits on network performance, proposing solutions like implementing additional networks. Star topology is mentioned as the implemented network design. The assignment concludes by referencing APA style, though there are no in-text citations in the main body.
