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.
Answer:
-3874₁₀ = 1111 1111 1111 1111 1111 1111 1101 1110₂
Explanation:
2's complement is a way for us to represent negative numbers in binary.
To get 2's complement:
1. Invert all the bits
2. Add 1 to the inverted bits
Summary: 2's complement = -N = ~N + 1
1. Inverting the number
3874₁₀ = 1111 0010 0010₂
~3874₁₀ = 0000 1101 1101₂
2. Add 1 to your inverted bits
~3874₁₀ + 1 = 0000 1101 1101₂ + 1
= 0000 1101 1110₂
You can pad the most signigicant bits with 1's if you're planning on using more bits.
so,
12 bits 16 bits
0000 1101 1110₂ = 1111 0000 1101 1110₂
They asked for double word-length (a fancy term for 32-bits), so pad the left-most side with 1s' until you get a total of 32 bits.
32 bits
= 1111 1111 1111 1111 1111 1111 1101 1110
Explanation:
