Task view is the option that you would not see on a Windows 10 Start menu, whereas if you click the Windows button, you can see tiles with different applications, all of your apps in the form of tiles you can distribute according to your own taste, and power button where you can choose whether you want to shut down your computer, put it to sleep, or log out.
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.
Answer:
Network Interface Card (NIC)
Explanation:
Also called Ethernet Card, the Network Interface Card (NIC) allows a computer or any device to make wired or wireless connections with other devices in a network. This connection made possible by the NIC allows the device to send and receive messages in the network.
An application of this is seen in Internet of Things(IoT) where devices communicate with one another. This is actually possible because all of the devices one way or the other have a network interface card.
