Answer:

C. Device Manager

Explanation:

Assuming you CAN access Windows Desktop from the PC, the first thing you would do is verify your Display Driver in Device Manager to see if the appropriate driver is installed, if not, install the drivers from the manufacturer's website, or use a software that does that. Other options would be to revert the driver to an older version.

The IPv4 address scheme has enough IP addresses to give every blade of glass in the world its own unique IP. True False
Andrew [12]

Answer:

False

Explanation:

IPv4 address are composed of four octets (8 bit numbers), ranging from <em>0.0.0.0 to 255.255.255.255</em>

All those 32 bits, in decimal notation, can form a total of

2^{32} = 4,294,967,296 different addresses.

Being more than 4 billion addresses and ignoring that some addressesare reserved for special uses, even present human population almost doubles that number.

So it is safe to state that IPv4 addresses is <u>not </u>enough to give every blade of grass its own IP.
