Answer:
B. Application programming interface
Explanation:
An application programming interface (API) is an interface or communication protocol between different parts of a computer program intended to simplify the implementation and maintenance of software. An API may be for a web-based system, operating system, database system, computer hardware, or software library.
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: I'm Not sure what kind of quiz this is
Explanation:
can you send another screenshot of the name of the quiz and what is the question asking for the quiz?
Answer:
The answer is "Option b".
Explanation:
Phishing is used by hackers to get sensitive data. It is a software tool, that offers online mail to use we can track the users. It also known as a state, in which clients will have to re-enter id and pass codes to validate themselves due to some changes to the system, and incorrect option can be defined as follows:
- In option a, It is used to attack on user system.
- In option c, It is used to provides unauthorized access.
- In option d, It is also known as malware, which is installed in user smartphones.
The largest dimensions we can make in an image with a pixelation which it is to 255×255. The largest image we can make with the pixelation widget would be 65,041 bits
