Answer:
D) can access main memory at the same time as the main CPU
Explanation:
DMA is short for Direct Memory Access, these controllers allow the device to transfer data directly to and from the memory modules without interfering with CPU processes. Therefore it can access main memory at the same time as the main CPU. Thus freeing up CPU processing power for other tasks while also retrieving the data necessary.
Options A and C can get you confused. We can choose option A if our argument is based entirely on digital images. The correct answer, however, is C: Number of pixels you see on your computer monitor.
Resolution describes the clarity and sharpness of a picture that can be measured by the number of pixels contained on a display monitor. It can be expressed by the number of horizontal (width) and vertical pixels (height) represented by a screen. The clarity and sharpness are always dependent on the resolution and size of the monitor.
If the pings are successful you are either on the same subnet and everything is configured correctly or ICMP echo is enabled on the router which it should be by default internally. Externally, ICMP can/should be disabled to avoid DOS attacks.
