I would start by checking the switches on the doors, one or more may be non functional and that is why the lights are staying on, secondly there are switches inside the seatbelt receptors that can tell whether your seatbelts are connected, it would appear that one is not recognizing that you have connected it.
It is dependant on whether the switches are in wired in a parallel or series configuration. If the switches are wires in parallel then both switches would have to be off to turn the light bulb off. Either switch could turn the light bulb on. If the switches are wired in series then both switches would have to be on to turn the light bulb on. Either switch could turn the light bulb off.
When switches or any circuit opening devices are in series with each other, they all have to be in the closed position to energize the load.When switches or any circuit opening devices are in parallel with each other, any one of the switches or circuit opening devices in the closed position will energize the load.
To test whether your computer has connectivity to the network, you can use the ping command followed by a known IP address or domain name. For example, you can type ping 8.8.8.8 (which is a Google DNS server) or ping www.google.com in the command prompt. This command sends packets to the specified address and displays the response time, indicating whether the network connection is functioning properly. If you receive replies, your computer is connected to the network; if not, there may be connectivity issues.
Yes. Some switches have, in any case - I know that the Cisco switches do. A switch needs both a MAC address and an IP address, if it is to be the endpoint of data communication; for example, if you want to test whether you can access the switch with the "ping" command, or if you want to configure it remotely.
ifconfig -a
The answer will depend on how they are connected: on only one side or more, whether they are nested, whether or not they form a convex tessellated area.
There are many reasons why communication may fail. For example (assuming a cabled network), there may be no connected cable, the network card may be damaged, or there may be a communication problem at higher levels. First, check to see whether the computer detects the cable. Then you might try a PING command, to see whether low-level communication works.
mdelete is a command to delete files over FTP. Whether or not it's a valid script command would depend on the scripting language.
chkcd
iptable in Linux
it will help you find out whether it is fully operational.
