16 Questions
What is the primary function of input devices in a computer system?
To allow users to enter commands and data
Secondary memory is volatile, which means its contents are lost when the computer is turned off.
False
What is the principle of abstraction used for?
To hide the internal functionality of a function from the users.

Secondary Memory (ROM)
Python is a low-level language.
False
What is the role of output devices in a computer system?
Output devices are hardware components of a computer system that are used to show or send data from the pc to the user or any other device.
According to the language hierarchy, Python is a _______________ language.
high-level
What is the purpose of abstraction in computer science?
To hide the internal functionality of a function
Python is an interpreted language.
True

Study Notes
Knowing the Computer
- A computer consists of basic parts: Central Processing Unit, Input, and Output devices
- Input devices (e.g., Keyboards, mice, scanners) allow users to enter commands and data
- Output devices are hardware components that show or send data from the computer to the user or other devices
Memory Hierarchy
- Primary Memory (RAM):
- Stores data and instructions currently being processed
- Volatile, meaning its contents are lost when the computer is turned off
- Secondary Memory (ROM):
- Non-volatile, meaning its contents are not lost when the computer is turned off
- Stores data and programs permanently
Principle of Abstraction
- Hides the internal functionality of a function from users
- Users only interact with the basic implementation of the function, while the inner workings are hidden
Language Hierarchy
- High-Level Language:
- Python is an example of a high-level language
- Uses a compiler or interpreter to execute code
- Interpreter (Python):
- Executes code directly, without the need for compilation
What is Python?
- Python is a popular programming language
- Characteristics:
- High-level
- Interpreted
- Dynamically-typed
- Simple
- Readable
- Versatile
Applications of Python
- Used for:
- Web development (server-side)
- Software development
- Machine Learning
- And many more
Why Python?
- Simple syntax
- Easy to learn
- Suitable for Software Development, Web Development, and Machine Learning
- Can be used for many projects
- Can lead to job readiness
