Final answer:
Collaborative editing software enables multiple users to concurrently create and edit web documents. The correct answer is 4.
Step-by-step explanation:
The technology that enables multiple users to create and edit web documents is collaborative editing software. While HTML, CSS, and JavaScript serve as the building blocks for creating and styling web content, it is the collaborative editing software that allows for real-time cooperation and document management among several users.
Examples of collaborative editing software include cloud storage services like Microsoft's OneDrive and Drive, which provide the ability to access files from any device and share them effortlessly. With these services, all changes to documents are saved automatically, ensuring that the most current version is always available to all collaborators.
Furthermore, word processors such as Microsoft Word and Docs offer review features, including comment boxes, Track Changes, and functions to suggest, accept, or reject changes, facilitating a cooperative editing process. Collaboration platforms offer even more comprehensive tools, integrating file sharing and storage, video conferencing, and task organizing into shared online workspaces. Hence the correct option is 4.
