Answer:

It may be that the amount of ram is not compatible with that computer, it may not support ram that is over 8 GB or higher, it may not be properly installed in the hardware, or the motherboard may not be able to read it.

Explanation:

Hardware and software is very unbalanced when it comes to new RAM being installed, as people complain about this exact same issue many times.

Which one of these is NOT a physical security feature you should check when inspecting your hotel room? (Antiterrorism Scenario

Lostsunrise [7]

Answer:

D. Lockbox or safe

Explanation:

Anti- terrorism is a disastrous event, planned by insurgents to take lifes. They can attack any unsecure environment.

When a guest lodges in a hotel, for security reasons (Anti-terrorism training), he/she must consider the distance of the room to an emergency exit, also the quality of the door mounted and then the functionality of the door and window locks.

Safes or lock-box are used to secure money and other material valuables, but not life.
