SharePoint

SharePoint is a web-based collaborative platform that integrates natively with Microsoft Office. Launched in 2001, SharePoint is primarily sold as a document management and storage system, but the product is highly configurable and its usage varies substantially among organizations.
According to Microsoft, SharePoint had 200 million users.
History.
Origins.
SharePoint evolved from projects codenamed "Office Server" and "Tahoe" during the Office XP development cycle.
"Office Server" evolved out of the FrontPage and Office Server Extensions and "Team Pages". It targeted simple, bottom-up collaboration.
"Tahoe", built on shared technology with Exchange and the "Digital Dashboard", targeted top-down portals, search and document management. The searching and indexing capabilities of SharePoint came from the "Tahoe" feature set. The search and indexing features were a combination of the index and crawling features from the Microsoft Site Server family of products and from the query language of Microsoft Index Server.
GAC-(Global Assembly Cache) is used to accommodate the shared assemblies that are specifically designated to be shared by applications executed on a system.
