+- TCP (Transport Control Protocol), breaks data up into packets that lets them be sent, with a checksum and other info (like sending a book over many letters)
+- UDP (User Datagram Protocol), no checking of messages, faster
+
+- IP (Internet Protocol), decides how to send data between systems (like a mail man)
+
+- HTTP codes
+    1xx Ongoing
+    2xx Ok
+    3xx Redirection
+    4xx Client error
+    5xx Server error
+
+- HTTP methods
+    GET
+    POST
