The standard web server services include:

1. HTTP (Hypertext Transfer Protocol): HTTP is the foundation of communication on the World Wide Web. It is the protocol used for transferring hypertext (text with links) and other media such as images, videos, and files between web servers and web browsers. HTTP operates on the default port 80.
2. HTTPS (Hypertext Transfer Protocol Secure): HTTPS is a secure version of HTTP that uses encryption to protect data transmitted between the web server and the client. It ensures secure communication and helps protect against eavesdropping, data tampering, and other security threats. HTTPS operates on port 443.
3. FTP (File Transfer Protocol): FTP is a protocol used for transferring files between a client and a server on a computer network. It allows users to upload and download files to and from a remote server. FTP operates on port 21 for control connection and optionally uses port 20 for data connection.
4. SMTP (Simple Mail Transfer Protocol): SMTP is an Internet standard for sending email messages between servers. It is responsible for the transmission and delivery of email over the Internet. SMTP operates on port 25.
5. POP3 (Post Office Protocol version 3): POP3 is a protocol used by email clients to retrieve email messages from a mail server. It allows users to download their emails to their local devices for offline access. POP3 operates on port 110.
6. IMAP (Internet Message Access Protocol): IMAP is an email retrieval and storage protocol that enables users to access and manage their email messages directly on the mail server. It offers more advanced features than POP3, such as folder management and server-side searching. IMAP operates on port 143.
7. DNS (Domain Name System): DNS is a distributed system that translates domain names (e.g., example.com) into IP addresses. It allows users to access websites using easy-to-remember domain names instead of numeric IP addresses. DNS operates on port 53.

These are some of the standard web server services commonly used on the internet. Different web servers and applications may also provide additional services or use different ports based on specific requirements and configurations.
