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
Application of a new technology and is much superior to rival products
B.) is what most employers are looking for
Answer:
C. Bell and LaPadula
Explanation:
The first mathematical models of multilevel security computer system was developed by Bell and Lapadula. Their full names are David Elliot Bell and Leonard J. Lapadula. Their model used to define the concept of modes of access,secure state machine and outlined the rules of access.
Answer:
When myMethod is invoked by a method in the same class as myMethod.
Explanation:
When you are in a class, it is like a different enviroment and within that class you can call a method without using the dot notation because you are still within the class.
Outside the class and despite the type of method, public, private or static, the dot notation will be required.
