What is an example of a client-based email system?

An example of a client-based email system is Outlook because it is primarily a software application installed on a user's device. Outlook allows users to manage their emails offline and connects to email servers to send and receive messages. This means that the email client itself processes emails directly on the user's machine, providing functionalities such as organizing messages, managing calendars, and facilitating contact management without requiring a constant internet connection.

In contrast, the other options, like Yahoo Mail, Gmail, and Hotmail, function as web-based email services. These services rely on a web browser to access the email interface and require an internet connection for sending and receiving messages. They leverage cloud storage to keep emails accessible from any device with internet connectivity, differing fundamentally from a client-based approach.
