CompTIA Network+: Registered Ports

With a range from 0 to 65535 split across three groups (those reserved for TCP/IP applications registered ports and dynamic ports) differentiating port numbers can be confusing. In this course you;ll learn how to identify and use the most common registered ports
You;ll examine port 1433 reserved for Structured Query Language (SQL) Server and when to use SQLnet port 1521 Remote Desktop Protocol (RDP) port 3306 and port 5060/5061 reserved for the Session Initiation Protocol (SIP).
You;ll then outline how IP protocols are used to facilitate Internet Protocol (IP) communication such as Transmission Control Protocol (TCP) User Datagram Protocol (UDP) Internet Control Message Protocol (ICMP) and Gateway Routing Encapsulation (GRE).
Lastly you;ll examine connectionless and connection-oriented services two data transmission services used to establish and terminate connections exploring how they behave at the network and transport layers of the OSI model.
