This Concept Map, created with IHMC CmapTools, has information related to: ch2 arch sys, Client Server The simple structure in which client processes interact with individual server processes in separate host computers in order to access the shared resources that they manage. The client/server model is organized around clients that request services and servers that provide services. Services might include information (such as the current weather) or computational services (such as complex calculations). Some Client/Server Architectural Patterns Thin-Client model: All application processing and data management by server only. Fat-Client model : Server only responsible for data management. The client machine implements application logic and interactions with user. Three-tier client-server: There is a layer between client and server that may provide data and/or application processing., System Architectures consists of Client Server The simple structure in which client processes interact with individual server processes in separate host computers in order to access the shared resources that they manage. The client/server model is organized around clients that request services and servers that provide services. Services might include information (such as the current weather) or computational services (such as complex calculations)., System Architectures includes Peer to Peer which interacting cooperatively as peers without any distinction between client and server processes or the computers that they run on. Peer to peer applications and systems have been successfully constructed that enable tens or hundreds of thousands of computers to provide access to data and other resources that they collectively store and manage. More scalable than client server., Client Server The simple structure in which client processes interact with individual server processes in separate host computers in order to access the shared resources that they manage. The client/server model is organized around clients that request services and servers that provide services. Services might include information (such as the current weather) or computational services (such as complex calculations). Client/Server Configurations Client-Server configurations are generally categorized in two types: Two-tier Configurations: consisting of a client and a server. Three-tier Configurations: includes another server that offloads certain functions from either the client and/or the server. Since there can be many intermediate servers, this may also be called n-tier. N-Tier Configurations: a type of three-tier set up that includes multiple intermediate servers.
