A file-hosting service, also known as cloud-storage service, online file-storage provider, or cyberlocker is an internet hosting service specifically designed to host user . These services allows users to upload files that can be accessed over the internet after providing a username and password or other authentication. Typically, file hosting services allow HTTP access, and in some cases, . Other related services include content-displaying hosting services (i.e. video and ), virtual storage, and remote backup solutions.
Personal file storage services are designed for private individuals to store and access their files online. Users can upload their files and share them publicly or keep them password-protected.
Document-sharing services allow users to share and collaborate on document files. These services originally targeted files such as PDFs, word processor documents, and spreadsheets. However many remote file storage services are now aimed at allowing users to share and synchronize all types of files across all the devices they use.
and sharing services allow users to create special folders on each of their computers or mobile devices, which are then synchronized across all devices. Files placed in this folder can be accessed through a website or mobile app and easily shared with others for viewing or collaboration.
Consumer products such as OneDrive and Google Drive have made file hosting and sharing more accessible and popular for personal and business use.
Content providers who encounter bandwidth congestion issues may use specialized services for distributing cached or static content. This is especially common for companies with a major internet presence.
Many businesses use file hosting services as part of their backup and disaster recovery strategies. By storing copies of important files offsite in a secure data center, they can quickly recover from data loss due to hardware failure, natural disasters, or other unexpected events.
Some online file storage services offer space on a per-gigabyte basis, and sometimes include a bandwidth cost component as well.

This course focuses on the physical mechanisms at the origin of the transition of a flow from laminar to turbulent using the hydrodynamic instability theory.
Cloud storage is a model of computer data storage in which the digital data is stored in logical pools, said to be on "the cloud". The physical storage spans multiple servers (sometimes in multiple locations), and the physical environment is typically owned and managed by a hosting company. These cloud storage providers are responsible for keeping the data available and accessible, and the physical environment secured, protected, and running. People and organizations buy or lease storage capacity from the providers to store user, organization, or application data.
File synchronization (or syncing) in computing is the process of ensuring that s in two or more locations are updated via certain rules. In one-way file synchronization, also called mirroring, updated files are copied from a source location to one or more target locations, but no files are copied back to the source location. In two-way file synchronization, updated files are copied in both directions, usually with the purpose of keeping the two locations identical to each other.
File sharing is the practice of distributing or providing access to digital media, such as computer programs, multimedia (audio, images and video), documents or electronic books. Common methods of storage, transmission and dispersion include removable media, centralized servers on computer networks, Internet-based hyperlinked documents, and the use of distributed peer-to-peer networking. File sharing technologies, such as BitTorrent, are integral to modern media piracy, as well as the sharing of scientific data and other free content.
