   Components of an Email: An email message typically consists of several components:
   
   • 
     Header: Contains information such as the sender's and recipient's email addresses, subject line, date, and other metadata.
     
   • 
     Body: The main content of the email, which can include text, images, attachments, or hyperlinks.
     
   • 
     Attachments: Files, such as documents, images, or videos, that can be included with the email.

   Email Protocols: Email communication relies on specific protocols for sending, receiving, and storing messages. The most commonly used protocols are:
   
   • 
     SMTP (Simple Mail Transfer Protocol): Used for sending emails from the sender's email server to the recipient's email server.
     
   • 
     POP (Post Office Protocol): Used for retrieving emails from an email server to the recipient's device.
     
   • 
     IMAP (Internet Message Access Protocol): Similar to POP, but it allows users to access and manage their emails on the server while synchronizing with multiple devices.
