It illustrates that each layer, from Layer 1 (Physical) up to Layer 5 (Application or higher), communicates with its corresponding layer on the other host using a specific layer protocol. The diagram emphasizes the interfaces between adjacent layers, such as the Layer 4/5 interface, Layer 3/4 interface, and so on, which define how data is passed up and down the stack. This layered approach allows for modularity and standardization, where each layer performs a specific set of functions without needing to know the intricate details of other layers. The physical medium serves as the ultimate transport for data between Host 1 and Host 2, with Layer 1 protocols managing the raw bit transmission. The representation is abstract, using generic \"Layer n\" labels and \"Layer n protocol\" to represent generalized networking concepts applicable across various network models like TCP/IP or OSI. The dashed arrows indicate the logical communication between peer layers, while the solid arrows within each host represent the flow of data between adjacent layers. This structure is fundamental to understanding how data traverses a network from its origin to its destination.",{"@graph":14,"@context":73},[15,34,56],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/template/","Template",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/template/general/","General",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/template/protocols-and-interfaces-in-network-layers/193728/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":49,"encodingFormat":47,"isAccessibleForFree":50,"interactionStatistic":51},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/protocols-and-interfaces-in-network-layers/193728.png","ImageObject",442,249,{"name":42,"@type":43},"วิน","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-09-28","2026-09-03",true,{"@type":52,"interactionType":53,"userInteractionCount":55},"InteractionCounter",{"@type":54},"ViewAction",9,{"@type":57,"mainEntity":58},"FAQPage",[59,65,69],{"name":60,"@type":61,"acceptedAnswer":62},"What is the purpose of the layered architecture shown in the diagram?","Question",{"text":63,"@type":64},"The layered architecture compartmentalizes network communication functions, allowing each layer to handle specific tasks and communicate with its peer layer on another host using defined protocols.
