All Flashcards
What is a module?
A pre-written block of code containing functions and procedures that can be imported into a program.
What is a software library?
A collection of pre-built procedures and functions that perform specific tasks, saving development time and effort.
What is an API?
Application Program Interface. A set of rules and specifications that define how software components should interact, providing instructions on how to use a library's procedures.
What is data abstraction?
Hiding complex implementation details and exposing only essential information to the user, simplifying interaction with complex systems.
What is the digital divide?
The unequal access to technology and the internet based on socioeconomic factors, geography, or other demographic variables.
What is cybersecurity?
The practice of protecting computer systems and networks from unauthorized access, theft, damage, or disruption.
What is an integer data type?
A data type that represents whole numbers without any fractional or decimal parts.
What is a float data type?
A data type that represents numbers with fractional or decimal parts.
What is a string data type?
A data type that represents a sequence of characters, typically used to store text.
What is a boolean data type?
A data type that represents logical values, either true or false.
What is modularity in programming?
Breaking down a program into smaller, independent modules or functions to improve code organization, reusability, and maintainability.
Why is code reuse important?
It reduces development time, improves code reliability, and promotes collaboration among developers.
Explain the benefits of using libraries.
Libraries provide pre-tested and optimized code, saving time and effort. They also enhance reliability and promote code sharing.
What is the purpose of control structures?
Control structures (sequence, selection, iteration) determine the order in which instructions are executed in a program, guiding the flow of execution.
Explain the concept of algorithm design.
Algorithm design involves breaking down a problem into smaller, manageable steps and creating a logical sequence of instructions to solve it.
What is the importance of program testing and debugging?
Testing and debugging ensure that a program functions correctly, identifies and fixes errors, and improves overall code quality and reliability.
Describe the positive impacts of computing innovations.
Computing innovations have led to advancements in communication, healthcare, education, and various other fields, improving quality of life and efficiency.
Describe the negative impacts of computing innovations.
Negative impacts include job displacement, privacy concerns, cybersecurity threats, and the digital divide, which can exacerbate social inequalities.
What is the importance of data representation in computing?
Data representation defines how data is stored and manipulated within a computer, influencing efficiency, accuracy, and the types of operations that can be performed.
Explain the benefits of using APIs.
APIs allow developers to easily integrate pre-built functionalities into their applications, promoting code reuse and saving development time.
What does the following code output?
python
from math import ceil
number = 4.2
result = ceil(number)
print(result)
5
Identify the error in the following code:
python
import random
number = random.randit(1, 10)
print(number)
The function randint is misspelled as randit. It should be corrected to randint.
What does the following code output?
python
from math import pi
print(pi)
3.141592653589793
Identify the error in the following code:
python
from math import log
number = -5
result = log(number)
print(result)
The math.log() function will raise a ValueError because it is being called with a negative number, which is not allowed for natural logarithms.
What does the following code output?
python
from math import pow
result = pow(2, 3)
print(result)
8.0
Identify the error in the following code:
python
import statistics
data = [1, 2, '3', 4, 5]
result = statistics.mean(data)
print(result)
The statistics.mean() function will raise a TypeError because the list data contains a string element ('3') while it expects numerical values.
What does the following code output?
python
from random import random
print(random())
A pseudo-random floating point number between 0.0 and 1.0.
Identify the error in the following code:
python
from math import factorial
number = 5.5
result = factorial(number)
print(result)
The math.factorial() function will raise a ValueError because it only accepts non-negative integer arguments, not floats.
What does the following code output?
python
from math import floor
number = 5.9
result = floor(number)
print(result)
5
Identify the error in the following code:
python
from math import exp
number = 'ten'
result = exp(number)
print(result)
The math.exp() function will raise a TypeError because it expects a numerical argument, not a string.
