Answer:
The data-link layer
Explanation:
The physical layer and data-link layer are often confused a lot especially in terms of what they do in the TCP/IP 7 layer protocol. The physical layer as the name suggests represents the physical devices like the cables and the connectors that join or interconnect computers together. This layer is also responsible for sending the signals over to other connections of a network. The data-link, on the other hand, translates and interprets these sent binary signals so that network devices can communicate. This layer is responsible in adding mac addresses to data packets and encapsulating these packets into frames before being placed on the media for transmission. Since it resides in between the network layer and the physical layer, it connects the upper layers of the TCP/IP model to the physical layer.
Most common PC operating systems
Answer:
C is the answer!
Explanation:
A hard drive contains your operating system which can include your settings and preferences that you included in your device. But it mostly is a storage device so we know it WOULD NOT BE (B.
WOULD NOT BE D beacause powering it back on wouldnt do anything but bring you back to the start.
WOULD NOT BE A beacuse when taking out the battery then putting it back in would just be like turning it off then back on beacuse that just hold the power to a device.
IT WOULD BE C, C IS THE ANSWER beacuse a CMOS batttery contains the main system settings and also contains information so i think C would be the best answer for this choice.
Hope this helps!
