# 7. Application Layer
The application Layer provides services to the end user. So this is the layer the user actually interacts with. 

These services are usually protocols that interact with the data that the user uses.

**Examples of services (protocols):**
- HTTP
- FTP
- IRC
- SSH
- DNS
- SMTP

For example a web browser like Google Chrome uses the HTTP protocol to browse files on the internet. And the mail client Outlook uses the SMTP protocol to send mail via the internet.
