Zoho is a cloud-based productivity suite that offers applications like word processing, spreadsheets, presentations, and collaboration tools. It integrates with Google, Microsoft, and Yahoo services and allows syncing of contacts. While it provides many basic functions for free, it has some limitations like limited fonts and no full spreadsheet support. Google and Microsoft Live also offer similar cloud-based productivity and collaboration suites. The adoption of cloud computing provides benefits like high scalability, low costs, and access from anywhere, but also raises concerns about data control, privacy, and security. Overall, Zoho provides a very user-friendly experience with many free features and high security integration.
