What different between HTTP protocol and HTTP server?

I just know that HTTP is the protocol that make client using browser like Chrome or Safari to get resource from web server. So HTTP is the 'protocol', But I see somewhere 'HTTP server' what is mean and What is the difference between a normal server and HTTP server?

I learned about OOP and I was thought that client-server both have HTTP method like:

client.HTTP.request(data)
server.HTTP.send(data)

Is that true?
