ping

A common method for troubleshooting the accessibility of devices.

A ping tests an ICMP echo message and its reply. Because ping is the simplest 

test for a device, it is the first to be used. If ping fails, try using traceroute.

Run ping to view the packets transmitted, packets received, percentage of packet 

loss, and round trip time in milliseconds.

port

1. An interface on an internetworking device (such as a router); a physical entity.

2. In IP terminology, an upper layer process that receives information from 

lower layers. Ports are numbered, and each numbered port is associated with a 

specific process. For example, SMTP is associated with port 25. A port number 

is also called a well known address.

3. To rewrite software or microcode so that it will run on a different hardware 

platform or in a different software environment than that for which it was 

originally designed.
