Episode 24: Common Ports and Protocols — FTP, HTTP, DNS, RDP
from Certified - The CompTIA A+ Audio Course Hosted by Dr. Jason Edwards
Understanding common network ports and protocols is essential for both the A Plus exam and real-world troubleshooting. This episode dives deep into the most important ones—such as File Transfer Protocol on port 21, Hypertext Transfer Protocol on port 80, Domain Name System on port 53, and Remote Desktop Protocol on port 3389. You’ll hear clear, repeated pronunciation and definitions of each protocol, their port numbers, and how they operate in a networked environment. We also explore how these protocols are used together and how failure in one service can affect overall network functionality. Exam questions often ask you to match a port number to a service or troubleshoot connectivity issues by identifying the blocked or misconfigured protocol. This episode is crafted to make that recall fast and accurate, even under pressure. Brought to you by BareMetalCyber.com.
