| Well known port range | 0 to 1023 |
| Network Topology: All devices logically configured in a single circle or ring. Data travels around the rung to different devices. | Ring |
| Command Line Tool: Shows network statistics, including a list of inbound and outbound connections for a system. | Netstat |
| A type of token ring topology that uses fiber optic cable and two rings. The second ring provides a redundant path that can be used if the first path fails. | Fiber Distributed Data Interface (FDDI) |
| Registered port range | 1024 to 49,151 |
| Wireless Protocols: Max Speed, Frequency and Range for 802.11n | 600 Mbps (300 Mbps common) 2.4 Ghz or 5.0 GHz, highest range (70m / 230ft) |
| Wireless Protocols: Max Speed, Frequency, and Range for 802.11g | 54 Mbps, 2.4 GHz, medium range (38m / 125ft) |
| This protocol is used to receive e-mail from a mail server. When this protocol is used, e-mail is generally deleted from the server as it is downloaded. | POP3 (Post Office Protocol) - Think of messages popping off the e-mail server. |
