| Layering involves separating the system or programs based on technical responsibilities, usually using an [[dido:public:ra:xapend:xapend.a_glossary:n:n-tier]]. Generally, these tiers are referred to as the //presentation tier//, //processing tier// and //data management tier//. Often the tiers are both logically and physically separated, with each tier running on its own dedicated platforms. In a [[dido:public:ra:xapend:xapend.a_glossary:d:distsystem|distributed system]], the tiers do not follow the [[dido:public:ra:xapend:xapend.a_glossary:c:client-server|client-server]] architecture but use a [[dido:public:ra:xapend:xapend.a_glossary:p:p2p]] architecture.
