esituskihti

Esituskihti is a Finnish term that translates to "presentation layer" in English. It refers to the top-most layer in a layered network architecture or a software system's design. The primary function of the esituskihti is to handle the way data is presented to the user or another application. This involves tasks such as data formatting, encryption/decryption, and compression/decompression.

In the context of network protocols, the esituskihti is often associated with the presentation layer of the OSI (Open Systems Interconnection) model. This layer acts as a translator between the application layer and the session layer. It ensures that data is transmitted in a format that the receiving system can understand, regardless of differences in data representation between the two systems. For example, it might handle character encoding conversions or the translation of data structures.

Within software architecture, the esituskihti is commonly found in the user interface (UI) or presentation tier of a multi-tiered application. This tier is responsible for all aspects of the user's interaction with the system. It displays information to the user and captures user input, which is then passed down to lower layers for processing. The separation of concerns provided by the esituskihti allows for independent development and modification of the user interface without affecting the underlying business logic or data management components. This promotes modularity, maintainability, and reusability of code.
