Multitier architecture. In software engineering, multitier architecture (often referred to as n-tier architecture) is a client–server architecture in which presentation, application processing and data management functions are physically separated. The most widespread use of multitier architecture is the three-tier architecture.
Multitier programming. Multitier programming (or tierless programming) is a programming paradigm for distributed software, which typically follows a multitier architecture, physically separating different functional aspects of the software into different tiers (e.g., the client, the server and the database in a Web application [ 1] ). Multitier ...
Data center network architectures. A data center is a pool of resources (computational, storage, network) interconnected using a communication network. [1][2] A data center network (DCN) holds a pivotal role in a data center, as it interconnects all of the data center resources together. DCNs need to be scalable and efficient to connect tens or ...
Hierarchical internetworking model. The Hierarchical internetworking model is a three-layer model for network design first proposed by Cisco in 1998. [1] The hierarchical design model divides enterprise networks into three layers: core, distribution, and access.
A computer network diagram of clients communicating with a server via the Internet. The client–server model is a distributed application structure that partitions tasks or workloads between the providers of a resource or service, called servers, and service requesters, called clients. [ 1 ] Often clients and servers communicate over a ...
The ANSI-SPARC three-level architecture. The ANSI-SPARC Architecture (American National Standards Institute, Standards Planning And Requirements Committee), is an abstract design standard for a database management system (DBMS), first proposed in 1975. [1] The ANSI-SPARC model however, never became a formal standard.
Clos network. In the field of telecommunications, a Clos network is a kind of multistage circuit-switching network which represents a theoretical idealization of practical, multistage switching systems. It was invented by Edson Erwin [1] in 1938 and first formalized by the American [2] engineer Charles Clos [3] in 1952.
Distributed computing. Distributed computing is a field of computer science that studies distributed systems, defined as computer systems whose inter-communicating components are located on different networked computers. [1][2] The components of a distributed system communicate and coordinate their actions by passing messages to one another in ...
