The most widespread use of multitier architecture is the three-tier architecture (for example, Cisco's Hierarchical internetworking model). N-tier application architecture provides a model by which developers can create flexible and reusable applications. By segregating an application into tiers, developers acquire the option of modifying or ...
In multitier programming, the different tiers are implemented using a single programming language. Different compilation backends take into account the destination tier (e.g., Java for a server and JavaScript for a web browser). Consequently, a functionality that is spread over tiers can be implemented in a single compilation unit of a ...
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.
Cache hierarchy, or multi-level cache, is a memory architecture that uses a hierarchy of memory stores based on varying access speeds to cache data. Highly requested data is cached in high-speed access memory stores, allowing swifter access by central processing unit (CPU) cores.
The three-tier is the common network architecture used in data centers. [10] However, three-tier architecture is unable to handle the growing demand of cloud computing. [11] The higher layers of the three-tier DCN are highly oversubscribed. [3] Moreover, scalability is another major issue in three-tier DCN.
In software engineering, a monolithic application is a single unified software application that is self-contained and independent from other applications, but typically lacks flexibility. [1] There are advantages and disadvantages of building applications in a monolithic style of software architecture , depending on requirements. [ 2 ]

The notion of a three-schema model was first introduced in 1975 by the ANSI/X3/SPARC three level architecture, which determined three levels to model data. [1]The three-schema approach, or three-schema concept, in software engineering is an approach to building information systems and systems information management that originated in the 1970s.
