What is file storage and synchronization? Distinguish between one way and two-way synchronization

File storage and synchronization are processes related to managing and maintaining files across multiple devices or locations to ensure data consistency and accessibility.

Synchronization involves updating files on one device or location to match the changes made on another. There are two main types of synchronization: one-way and two-way synchronization.

1. One-Way Synchronization:

   – In one-way synchronization, changes are propagated from one source (e.g., a master device or central server) to one or more target devices or locations.

   – It ensures that the target devices or locations mirror the content of the source. Any changes made on the source are replicated to the target devices.

   – This is often used in scenarios where one central repository contains the authoritative copy of the data, and other devices or locations are meant to have identical copies.

2. Two-Way Synchronization:

   – Two-way synchronization, also known as bidirectional synchronization, allows changes to flow in both directions between devices or locations.

   – It ensures that changes made on either the source or target are reflected on the other. If a file is modified on one device, the change is updated on the other device, and vice versa.

   – Two-way synchronization is useful in scenarios where multiple users or devices need to collaborate and update the same set of files, and changes should be harmonized across all locations.

In summary, file storage and synchronization involve managing files across multiple devices or locations, and the key distinction lies in how changes are handled. One-way synchronization pushes changes from a single source to one or more targets, while two-way synchronization allows changes to flow bidirectionally between devices or locations, ensuring that all copies are up to date.
