The statement given "once a class has inherited from another class, all the instance variables and methods of the parent class are available to the child class. " is true because hen a class inherits from another class, it gains access to all the instance variables and methods of the parent class.

This is one of the fundamental principles of inheritance in object-oriented programming. The child class, also known as the subclass or derived class, can use and modify the inherited variables and methods, as well as add its own unique variables and methods.

Inheritance allows for code reuse and promotes a hierarchical relationship between classes. It enables the child class to inherit the behavior and attributes of the parent class, while still maintaining its own specialized functionality. Therefore, the statement that "once a class has inherited from another class, all the instance variables and methods of the parent class are available to the child class" is true.

The computer's BIOS (Basic Input/Output System) is responsible for getting the system up and running and finding an operating system to load.

When a computer is turned on, the first piece of software that runs is the BIOS. The BIOS is a small program stored on a chip on the motherboard that initializes and tests the computer's hardware components, such as the CPU, memory, and storage devices. Once the hardware is tested and initialized, the BIOS searches for an operating system to load.

It does this by looking for a bootable device, such as a hard drive or CD-ROM, that contains a valid operating system. If the BIOS finds a bootable device, it loads the first sector of the device into memory and transfers control to that code, which then loads the rest of the operating system. If the BIOS cannot find a bootable device, it will display an error message or beep code indicating that there is no operating system to load.

Here's a Python program that reads text data from a file and generates a printed list of up to the 10 most frequent words in the file, along with each word's count in the file, in descending order of frequency (separated by a tab). It also generates a log-log plot of word count versus word rank using Matplotlib.

```python

import matplotlib.pyplot as plt

from collections import Counter

# Read text data from file

with open('filename.txt', 'r') as f:

   text = f.read()

# Split text into words and count their occurrences

word_counts = Counter(text.split())

# Print the top 10 most frequent words

for i, (word, count) in enumerate(word_counts.most_common(10)):

   print(f"{i+1}. {word}\t{count}")

# Generate log-log plot of word count versus word rank

counts = list(word_counts.values())

counts.sort(reverse=True)

plt.loglog(range(1, len(counts)+1), counts)

plt.xlabel('Rank')

plt.ylabel('Count')

plt.show()

```

First, the program reads in the text data from a file named `filename.txt`. It then uses the `Counter` module from Python's standard library to count the occurrences of each word in the text. The program prints out the top 10 most frequent words, along with their counts, in descending order of frequency. Finally, the program generates a log-log plot of word count versus word rank using Matplotlib. The x-axis represents the rank of each word (i.e., the most frequent word has rank 1, the second most frequent word has rank 2, and so on), and the y-axis represents the count of each word. The resulting plot can help to visualize the distribution of word frequencies in the text.

The required program that generates the output described above is

```python

import matplotlib.pyplot as plt

from collections import Counter

# Read text data from file

with open('filename.txt', 'r') as f:

  text = f.read()

# Split text into words and count their occurrences

word_counts = Counter(text.split())

# Print the top 10 most frequent words

for i, (word, count) in enumerate(word_counts.most_common(10)):

  print(f"{i+1}. {word}\t{count}")

# Generate log-log plot of word count versus word rank

counts = list(word_counts.values())

counts.sort(reverse=True)

plt.loglog(range(1, len(counts)+1), counts)

plt.xlabel('Rank')

plt.ylabel('Count')

plt.show()

```

The code  begins by reading text data from a file called  'filename.txt '. The 'Counter' module from Python's standard library is then used to count the occurrences of each word in the text.

In descending order of frequency, the software publishes the top ten most frequent terms, along with their counts. Finally, the program employs Matplotlib to build a log-log plot of word count vs word rank.
