b) A function definition provides the function name, return type,and arguments.

A function definition in a class typically includes the function name, return type, and arguments.  However, it does not necessarily provide the class name or the function statements. Therefore, statement (b) is the correct option. In a class, the programmer usually first declares the member functions and then defines them separately. The function definition contains the implementation of the function, including the statements that define its behavior. It does not involve a modulus operator preceding the function name.

The authentication method that provides non-repudiation is the use of digital signatures.

Digital signatures are cryptographic mechanisms used to verify the authenticity and integrity of electronic documents or messages. They provide non-repudiation by ensuring that the sender of the message cannot deny sending it. Digital signatures use a combination of public and private keys to encrypt and decrypt the message. The sender signs the message with their private key, and the recipient can verify the signature using the sender's public key. This process ensures that the message came from the claimed sender and has not been altered during transmission.

Structured Query Language (SQL) is a database management system that allows analysts to extract data from a relational database. Relational databases organize data into tables, rows, and columns. SQL helps to simplify the management of Big Data by reducing the complexity of traditional data management techniques.

What is Big Data?

Big Data is a term that refers to large volumes of structured and unstructured data that are difficult to process using traditional data processing methods. It includes a wide range of data types, including text, images, and video. The scale of Big Data makes it difficult to manage and analyze without specialized tools and techniques.

Big Data management is challenging because it involves processing large volumes of data from different sources, often in real-time. SQL provides a way to manage Big Data more efficiently by providing a flexible and scalable platform for data analysis and management.An analyst can most effectively manage Big Data with SQL. SQL allows analysts to extract, manipulate, and analyze data from large, complex data sets in real-time.

With SQL, analysts can quickly and easily find patterns, relationships, and insights in Big Data that might otherwise go unnoticed. Therefore, an analyst can most effectively manage Big Data with SQL.

The digital signaling rate that has a frame containing a framing bit and 24 channels where each channel holds a single 8-bit DS0 data sample is DS1.

DS1, also known as T1, is a digital transmission format that uses pulse code modulation (PCM) to encode voice or data signals into a 1.544 Mbps digital signal.

The DS1 frame is composed of 24 time slots or channels, where each channel is 8 bits long and can carry a single DS0 signal. One of the channels is reserved for framing and signaling information, and the remaining 23 channels carry user data.

DS1 is widely used in telecommunications networks and is commonly used to transmit voice and data traffic between central offices and customer premises.

Data is stored in binary on computers. In addition to being a trustworthy method of storing data, binary is the only system that computers can comprehend. Transistors in a computer's primary memory alternate between high and low voltage levels, sometimes at 5V and other times at 0.

The binary number system uses two distinctive digits to represent numerical values (0 and 1). The majority of computing systems employ binary numbering, which interprets a voltage input of 0 as off and a voltage input of 1 as on, to represent the on/off state of electronic circuits (i.e., switches).

The binary number system, often known as the base-2 number system, is a way of expressing numbers that uses just two permutations of the digits zero (0) and one (1) to denote counting (1). All of the data that computers process and store, including numbers, words, films, pictures, and music, is done so using the binary number system.

The value of the variable all_different is: all_different = No

Does each box at the fruit stand contain a different fruit? Set all_different to True if each box contains a different fruit or to False if multiple boxes contain the same fruit.

Hint: You don't have to write code to calculate the True/False value for all_different. Just look at the inventory table and assign all_different to either True or False according to what you can see from the table in answering the question.

box ID  fruit name     count

53686   kiwi             45

57181   strawberry     123

25274   apple            20

48800   orange          35

26187   strawberry     255

57930   grape          517

52357   strawberry     102

43566   peach       40

all_different = ...

From the hint given, we can see that writing a code is not necessary.

All we need to do is to scan through the table.

From the given table, we can see that there are several fruits on the table.

These include peach, kiwi, grape, strawberry, etc.

Since the fruits are different, then the value of the variable all_different is:

all_different = No
