TLS is the new name for SSL. Namely, SSL protocol got to version 3.0;
TLS 1.0 is "SSL 3.1". TLS versions currently defined include TLS 1.1
and 1.2. Each new version adds a few features and modifies some internal
details. We sometimes say "SSL/TLS".
HTTPS is HTTP-within-SSL/TLS.
SSL (TLS) establishes a secured, bidirectional tunnel for arbitrary binary data between two hosts.
HTTP is a protocol for sending requests and receiving answers, each request and answer consisting of detailed headers and (possibly) some content. HTTP is meant to run over a bidirectional tunnel for arbitrary binary data; when that tunnel is an SSL/TLS connection, then the whole is called "HTTPS".
