E-mail is a service that lets users send and receive letters using the Internet. It can be divided into web-based e-mail and e-mail that uses POP3.
Web-Based E-Mail
Web-based e-mail includes services such as Gmail and Naver. With this type of mail, users can access the corresponding site on the Internet without a separate program, then manage and receive mail there.
- Advantage: Because no separate program is used, it can be used easily when several people share one computer or in places where installing a separate program is difficult.
- Disadvantage: Users must use the interface provided by the company and must access that website.
POP3
With a POP3 server, users can send and receive mail using a POP3-supported e-mail client such as Outlook Express.
- Advantage: Because it simply delivers letters, any program that supports POP3 can be used, so users can choose a program that is convenient for them.
- Disadvantage: A program must be installed to check e-mail contents.
