PING Command

Loopback test

a signal that tests the network interface card to ensure it is functioning properly

The PING command works with the IP address of a host that could be

any network device (computer, server, router, printer)

PING can be combined with other sub commands called

switches

If you PING a host and get the message "Request timed out," this could mean:

the host is powered down; the host is up and running, but it's using a firewall to block PING requests

After the 4 data packets are sent to the host device, hopefully,

the host will send data packets back to the original device

Echo reply request

the reply that the host device will send to the home device after the PING command

If you PING a host and get the message "Destination host unreachable," this could mean:

the router doesn't have information on how to route data to the destination; the remote host is down; home device is not connected to network

If there is an echo reply request, this means that

there is a network connectivity between the home device and the host

If there is no echo reply request after the PING command,

there is no connectivity between the home device and the host

(T/F) Using the PING command should be the first step when a network connectivity isn't working

true

PING command

used to test network connectivity, network interface card, and DNS name resolution issues

The reasons for packet lost include:

network congestion, faulty hardware

If you PING a host and get only 3 packets back instead of 4, this is known as

packet loss

Switches are used to alter the

parameters of the PING utility

In the Command Prompt, the code for checking out the PING switches is

ping /?

In order to start PING, you open up the Window's Command Prompt and type in

ping along with IP address of host

In order to perform the loopback test, in the Command Prompt you type in

ping localhost

If you wanted to test the connectivity between your device and Yahoo, you would type in the Command Prompt

ping yahoo.com

After typing PING and the IP address of the Command Prompt, the PING utility will

send out 4 data packets to the IP address of the host
