What happens when you are using non volatile storage? Where does it go?
Non volatile storage is stored in a memory chip that retains its data even when the power is turned off.
What is non-volatile storage?
Non-volatile storage is indeed a type of computer memory that can preserve data even after the power is turned off. In contrast, volatile memory requires constant power to maintain data. Non-volatile memory is commonly used to describe storage in semiconductor memory chips that store data in floating-gate memory cells made up of floating-gate MOSFETs (metal-oxide-semiconductor field-effect transistors), including flash memory storage including such NAND flash as well as solid-state drives (SSD).
Non volatile storage is used to store data that needs to be persistent, even when the power is turned off. This could be data like the operating system files on a computer, or user data like documents or photos. Non volatile storage can be either internal, like a hard drive, or external, like a USB flash drive.

______ is a disk storage technique that improves performance and fault tolerance.
The disk storage technique that improves performance and fault tolerance is called Redundant Array of Independent Disks (RAID).
RAID is a technology used to improve the storage system's performance, reliability, and availability by grouping two or more hard drives to work as a single logical unit. RAID can be used to store the same data in different places, which is called redundancy.RAID has several levels, each with its own configuration and fault-tolerance characteristics. These include RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, and RAID 50.RAID 0 is the simplest type of RAID that improves the system's performance by distributing data across two or more disks, allowing for faster data access. However, RAID 0 does not provide fault tolerance since there is no redundancy.RAID 1 uses disk mirroring, which involves duplicating data on two or more disks, ensuring data is always available even if one disk fails. However, RAID 1 is expensive because it requires twice the amount of storage.RAID 5 uses striping and parity data across multiple disks to improve performance and provide fault tolerance. In this level, parity data is used to rebuild data in case one disk fails. RAID 5 can survive the failure of one disk, and it requires at least three disks.RAID 6 is an extension of RAID 5 that can survive the failure of two disks. It uses striping with double parity, which ensures data can be rebuilt even if two disks fail. RAID 6 requires at least four disks.RAID 10, also known as RAID 1+0, combines disk mirroring and striping to provide both performance and fault tolerance. It requires at least four disks.RAID 50, also known as RAID 5+0, combines the block-level striping of RAID 0 with the distributed parity of RAID 5. It provides high performance and fault tolerance and requires at least six disks.RAID technology is widely used in modern storage systems and is an essential tool in ensuring data availability, integrity, and performance.

Analyze the following code:
class Circle {
private double radius;
public Circle(double radius) {
radius = radius;
} }
A. The program has a compilation error because it does not have a main method.
B. The program will compile, but you cannot create an object of Circle with a specified radius. The object will always have radius 0.
C. The program has a compilation error because you cannot assign radius to radius.
D. The program does not compile because Circle does not have a default constructor.
The following code is defining a Circle class with a private radius field and a constructor that takes a double value as a parameter and assigns it to the radius field:
class Circle {
private double radius;
public Circle(double radius) {
radius = radius;
}
}
However, this code has a problem with the constructor. Specifically, it is not assigning the constructor parameter to the class variable.
Option C is the correct answer: the program has a compilation error because you cannot assign radius to radius. To fix the issue, the constructor should refer to the class variable using the 'this' keyword:
public Circle(double radius) {
this.radius = radius;
}
This ensures that the parameter value is assigned to the class variable, rather than just assigning the parameter value to itself.
Option A is incorrect because a main method is not required for every class, especially for classes that are intended to be used as objects in a larger program. Option B is also incorrect because you can create an object of Circle with a specified radius, but the current code will not assign the specified radius to the object's radius field. Option D is also incorrect because a default constructor is not needed if a constructor with parameters is provided.

Which of these is a valid byte? Check all that apply. A) 00000000. B) 1011011. C) 10022011. D) 11100.
The valid bytes are A, B, and D. A valid byte is a sequence of 8 binary digits (bits) representing an integer (0-255) in the binary (base 2) numeral system. The valid bytes in this case are 00000000, 1011011, and 11100, as they are all sequences of 8 binary digits.
What is bytes?Bytes are units of digital information that are most commonly used to measure computer storage and memory. A single byte is composed of 8 bits, and is the smallest unit of memory that can be addressed in modern computer systems. A byte contains enough data to represent one character of information, such as a letter, number or symbol. The storage capacity of a computer is measured in bytes, and the size of a file or program is also measured in bytes. For example, a typical text document might contain 500 bytes of data.

Write a program that accepts three decimal numbers as input and outputs their sum.
Answer:
void sum(float a, float b, float c){
printf("%0.3f", (a + b + c));
}
Explanation:
The answer given is written in C, but the same function can be reimplemented easily in whatever language this is required in.
Recall that a floating-point number can be expressed as (−1)s(1+f)2e where s,f and e are binary numbers. Recall that s is the sign indicator, f the mantissa (or fractional part), and e the (signed) exponent. Suppose the sign is 1 bit long, the mantissa 24 bits long, and the exponent has 9 bits. What are the largest and smallest positive numbers in this computer system? Provide the theoretical expressions for the decimal version of the largest and smallest numbers, and also use Matlab to evaluate the expressions.
The largest positive number is 3.4028 x \(10^{38\) and the smallest positive number is 1.1755 x \(10^{-38\).
A floating-point number can be expressed as (-1)^s * (1+f) * 2^e, where s, f and e are binary numbers. Here, s is the sign indicator, f is the mantissa (or fractional part), and e is the (signed) exponent. If the sign is 1 bit long, the mantissa is 24 bits long, and the exponent has 9 bits, then the largest and smallest positive numbers in this computer system are as follows:Largest positive number: When all the bits are used for the mantissa and exponent, the value of f and e will be 2^24-1 and 2^9-1 respectively. This will give us the largest possible number in this computer system, which can be expressed as: (theoretical expression). Using Matlab, the expression can be evaluated as follows:>>ans = 3.4028e+38Smallest positive number: When all the bits are used for the mantissa and exponent, the value of f will be 1 and e will be -126 (the smallest possible exponent value). This will give us the smallest possible number in this computer system, which can be expressed as: (theoretical expression). Using Matlab, the expression can be evaluated as follows:>>ans = 1.1755e-38
Therefore, The largest positive number is 3.4028 x \(10^{38\) and the smallest positive number is 1.1755 x \(10^{-38\).

What is the mistake in this python code
emotion = input("How are you feeling today?")
print(f"Im feeling {emotion} too!")
if == sad:
print("I hope you have a good day")
if == happy:
print("Me too")
You will need to set the if statements to:
if emotion == "sad":
print("I hope you have a good day")
if emotion == "happy":
print("Me too")
Make sure to indent the print code, and the first part of your code is correct!
The mistake in this Python code is that the if statements are missing the variable name that they should be checking. The correct syntax for an if statement is `if condition:` where `condition` is some expression that evaluates to either True or False.
Also, the values `sad` and `happy` are not defined as strings in the code, so the comparison with these values will result in a NameError.
Here's the corrected code:
emotion = input("How are you feeling today?")
print(f"I'm feeling {emotion} too!")
if emotion == "sad":
print("I hope you have a good day.")
if emotion == "happy":
print("Me too.")
Note that I've added the variable name `emotion` to the if statements, and defined the comparison values as strings. Also, I've added indentation to the print statements so they are executed only when the condition is true.

All programming languages require Function Prototypes to be coded by the developer. Group of answer choices True False
False. Not all programming languages require function prototypes to be coded by the developer. Some programming languages, like Python, do not require function prototypes.
1. Function prototypes are declarations that specify the name, return type, and parameters of a function. They provide information about the function to the compiler before the function is defined.
2. While some programming languages, like C, require function prototypes to be coded by the developer before the function definition, not all programming languages have this requirement.
3. For example, in Python, function prototypes are not needed. The function can be defined and used directly without any prior declaration or prototype.
Function prototypes are declarations that specify the name, return type, and parameters of a function. They provide information about the function to the compiler before the function is defined. This allows the compiler to check the function calls and ensure that the arguments passed to the function match the expected types and number.
However, not all programming languages require function prototypes to be coded by the developer. Some programming languages, like C, require function prototypes to be coded before the function definition. In C, the function prototype is usually placed at the beginning of the code or in a header file. It serves as a forward declaration of the function, providing information about its name, return type, and parameters.
On the other hand, in languages like Python, function prototypes are not needed. Python is an interpreted language, and its runtime environment is able to dynamically resolve function calls based on the arguments provided. In Python, the function can be defined and used directly without any prior declaration or prototype.
This flexibility can make Python code more concise and easier to read, but it also means that the compiler cannot perform static type checking on function calls.
