The survey responses "good, better, best" represent Ordinal data. This is because they represent a ranking or order of preference, without providing a specific numerical value or equal intervals between them.

The survey responses "good, better, best" would be classified as ordinal data. Ordinal data is a type of categorical data that can be ranked or ordered according to a particular characteristic or attribute. In this case, the responses can be ordered from good to better to best, indicating an increasing level of preference or satisfaction. Nominal data, on the other hand, is categorical data that cannot be ordered or ranked, such as colors or types of fruit. Interval data involves continuous numerical values where the differences between values are meaningful, such as temperature in Celsius or Fahrenheit. Ratio data is similar to interval data but has a true zero point, such as height, weight, or time.

The decryption function in the 'textbook' RSA encryption scheme is:

plaintext = ciphertext^d mod n

where d is the private decryption key and n is the product of two large prime numbers.

In RSA encryption, the decryption function involves raising the ciphertext to the power of the private key, d, and taking the result modulo n. The private key, d, is calculated from the two large prime numbers used in the encryption process. The resulting plaintext is the original message that was encrypted using the public key.

This decryption function works because of the mathematical properties of the RSA algorithm, which rely on the fact that it is computationally difficult to factor large numbers into their prime factors. Therefore, an attacker who intercepts the ciphertext would not be able to easily compute the private key and decrypt the message.

For a identifying weak entity, it is necessary to add the key of the parent entity to the weak entity's relation so that this added attribute becomes part of the weak entity's primary key.

An identifying weak entity is a type of entity in a database design that does not have a primary key of its own, but depends on the existence of a parent entity to form a composite primary key. The primary key of the parent entity is used as a foreign key in the weak entity, and is combined with the weak entity's own attributes to form a composite primary key.

This is in contrast to a non-identifying weak entity, which also does not have a primary key of its own, but does not depend on the existence of a parent entity to form a primary key. In this case, a separate table is created for the weak entity, and the primary key of the parent entity is stored as a foreign key in the weak entity table, but is not part of the weak entity's primary key.

The original DES cipher used a 56 bit key  is the strongest option among these would be the Triple DES cipher.

While a 72-bit key encryption would increase the key size, Triple DES provides a more robust encryption method by applying the DES cipher three times, making it significantly more resistant to attacks compared to a single DES cipher or a Caesar cipher, which is a much simpler and weaker encryption technique.

Double digit key encryption is not a well-defined concept and therefore cannot be compared to the other options. Triple Data Encryption Standard (Triple DES) is a symmetric block cipher-based cryptography standard that uses fixed length keys with three passes of the DES algorithm.

As a symmetric cryptographic scheme, DES implementations rely on the same secret keys shared between the sender and the recipient. 3DES is an encryption algorithm widely used in the finance industry.

There are several possible reasons why aggregate processing on arrays is not permitted in C. The two main reasons why aggregate processing on arrays is not permitted in C are type safety and memory management.

1. Type safety: C is a statically typed language, which means that the type of a variable must be specified at compile time. When processing aggregates, such as arrays, the compiler needs to be able to verify that the operations being performed are compatible with the type of the elements in the array. If aggregate processing was allowed on arrays, it would be difficult to maintain type safety since the type of the array would depend on the size and type of the elements it contains. This could lead to runtime errors that are difficult to detect and debug.

2. Memory management: Arrays in C are typically allocated on the stack or the heap. When an array is declared on the stack, it has a fixed size that is determined at compile time. This means that if aggregate processing was allowed on arrays, it would be difficult to allocate and deallocate memory dynamically since the size of the array would change at runtime. On the other hand, if an array is declared on the heap, it can be resized dynamically, but this can be expensive in terms of memory allocation and deallocation.

In summary, by disallowing aggregate processing on arrays, C provides a more reliable and efficient memory management system that helps ensure program stability and safety.

Relationship

The relationship between the life cycle of an AsyncTask and an Activity is that an AsyncTask is often used within an Activity to perform background tasks, such as fetching data from the internet or processing large amounts of data, without blocking the UI thread. However, the AsyncTask's life cycle is not tied to the Activity's life cycle, which can lead to potential problems.

Problems

One common problem is that when an Activity is destroyed (e.g., due to a configuration change, like screen rotation), the AsyncTask may continue to execute in the background and try to update the UI of the destroyed Activity, leading to memory leaks or crashes.

How to avoid problems?

To avoid these problems, you can:

1. Use proper cancellation: Implement proper cancellation for your AsyncTask, so that when the Activity is destroyed, the AsyncTask is also cancelled, preventing it from executing on a non-existent Activity.

2. Use WeakReference: By using a WeakReference to the Activity, you can prevent strong references from causing memory leaks. If the Activity is destroyed, the AsyncTask can detect that the reference is gone and avoid trying to update the UI.

3. Use alternative solutions: Consider using alternative solutions like LiveData and ViewModel from Android Architecture Components or RxJava, which provide better handling of the Activity's life cycle and background processing. These solutions ensure that the background task is automatically managed according to the life cycle of the associated Activity or Fragment.
