Answer:
mknod
Explanation:
When the user wants to configure a camera device on his Linux computer and the user recognizes that his device does not have a device-specific file. Thus, the user could use the mknod command on his computer to set up an equipment file because it is the command that is used to create a fresh file and these files are not the same as the normal file.
So, the following answer is correct according to the following scenario.
I would hold down the power button for about 10 seconds, and then try pressing the power button again.
If you are using a desktop, try unplugging it and then plugging it and plugging it back in again. Then try pressing the power button again. If this does not work, then unplug your computer again, but now plug in something else into the same spot, like a lamp, or a phone charger, and see if they work. If they do not work, then it is the power outlet that is broken, not your computer. If they do work, then there is most likely something wrong with your computer or your power cord. Try powering on your computer using a different power cord. If this does not work, you should take your computer some where to get it checked, and fixed, if necessary.
If you are using a laptop, try charging it, and then hold down the power button for about 10 seconds, and then try pressing the power button again. if this does not work, you should take your computer some where to get it checked, and fixed, if necessary.
Since java.util.PriorityQueue doesn't use the Cloneable interface, I think it's safe to say that Serializable interfaces are implemented in all instances.
Answer:
There could be a collision if a hidden node problem occurs.
Explanation:
CSMA/CA(carrier sense multiple access/ collision avoidance) is a multiple access method in wireless networking, that allows multiple node to transmit. Collision avoidance of this method is based on preventing signal loss or downtime as a result of collision of transmitting multi signals.
If a node at step 4(transmit frame) sends the first frame, the node still needs to send a RTS(request to send) and to receive a Clear to send (CTS) from the WAP, the is to mitigate the issue of hidden node problem as all frame are treated as unit, so other listening nodes, not detected would seek to connect and transmit as well.
