Ports & Protocols

Ports & Protocols Welcome to the Cybrary IT A+ Certification course for the CompTIA Exam, in today’s lesson we are going to explore computer Ports and Protocols. Ports are defined as communication endpoints which are more 65,000 possible ports a network communication device can connect with. You’ll learn how ports are used, why they are reserved for specific use, what the “5-Layer Diagram” is, how to construct it, and what happens at each level of this layer, specifically the Transport layer. FYI:  HOMEWORK Google Master Port List, and you’ll find a variety of standardized list of TCP and UDP Ports.  You should note however, that the IANA site (www.IANA.org) should always be your go-to resource for port assignments.  This is an invaluable reference tool to have at the ready. Known officially as the Service Name and Transport Protocol Port Number Registry, it was last updated as of July 8, 2015. http://www.iana.org/assignments/service-names-port-numbers/service-names-port-numbers.xhtml
