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
Answer:
Task manager
Explanation:
Allows you to force quit applications.
We interact with products of graphic design every day. Graphic design is used to make the billboards we drive by on our way to school, the pleasing layout of our favorite website, the covers of our most loved book, even the traffic signs we pass. The evolution of graphic design has only improved our visual world. Designers are constantly seeking to find the best and most effective ways of presentation, which means that the traffic signs you see are in a bold, large font so that you don't have to squint to read them. This is a result of designer's constant process of seeking out the most effective tools of visual communication that will make our lives easier, whether we're aware of it or not.
Answer: High cohesion
Explanation: Cohesion in general refers to make a couple of the functions or characteristics to share the functions and content . In the field of computer science , cohesion is the best characteristic that can be included in the design because it connect the various software so that they can share the responsibilities , function and can achieve better output through this. Thus high cohesion is the most preferred factor.
