In email, which of the following mode(s) is/are included in the Post Office Protocol (POP)?
I. Delete Mode
II. Keep Mode

Correct option is D

The Post Office Protocol (POP) includes both Delete Mode and Keep Mode. Delete Mode removes messages from the server after download, while Keep Mode leaves a copy on the server. This flexibility allows users to manage messages based on their needs for storage and access.
Important Key Points:
1. Delete Mode: Deletes messages from the server after they are downloaded to a device, freeing server space.
2. Keep Mode: Retains a copy of downloaded messages on the server, allowing access from multiple devices.
3. User Control: POP modes provide users with control over message storage and retrieval based on device usage.
Knowledge Booster:
· IMAP Protocol: Unlike POP, the Internet Message Access Protocol (IMAP) synchronizes messages across multiple devices, allowing more dynamic access.
· SMTP Protocol: Used for sending email rather than retrieving, unlike POP which focuses on message retrieval.
· Email Storage Options: With advancements, users also have cloud-based storage that provides real-time access and storage without deleting messages.
