Exploring Computer Science and Python

What is the primary function of an operating system?

• To increase battery life

• The primary function of an operating system is to manage computer hardware and software resources.

• To enhance graphics performance

• To provide internet connectivity

Explain the difference between a process and a thread.

• A process is always faster than a thread.

• Threads cannot communicate with each other within a process.

• A process is an independent execution unit with its own memory, while a thread is a lightweight unit of a process that shares memory with other threads.

• A process is a lightweight unit that shares memory with other processes.

What is Python's built-in function to read a file?

• open()

• fetchFile()

• readFile()

• loadFile()

Describe the role of the kernel in an operating system.

• The kernel stores all user data and files on the disk.

• The kernel is a type of application that runs on the operating system.

• The kernel manages system resources and facilitates communication between hardware and software in an operating system.

• The kernel is responsible for user interface design.

What is the purpose of a virtual memory?

• To store permanent data on the hard drive.

• To increase the processing speed of the CPU.

• To manage network connections efficiently.

• The purpose of virtual memory is to extend the available memory of a computer by using disk space to simulate additional RAM.

How do you create a function in Python?

• create function_name(parameters) { function body }

• function_name(parameters) => function body

• function function_name(parameters) { return function body }

• def function_name(parameters): # function body

What is the difference between a list and a tuple in Python?

• Lists are mutable; tuples are immutable.

• Tuples are mutable; lists are immutable.

• Lists are faster than tuples in all cases.

• Lists can contain only numbers; tuples can contain any data type.

Explain the concept of multitasking in operating systems.

• Multitasking refers to the process of managing hardware resources exclusively.

• Multitasking allows only one process to run at a time.

• Multitasking allows multiple processes to run concurrently by rapidly switching between them, managed by the operating system.

• Multitasking is the ability to run multiple operating systems simultaneously.

What command is used to install packages in Python?

• pip install

• python install

• install package

• pip get

What is the significance of the 'main' function in a Python script?

• The 'main' function is used to define global variables only.

• The 'main' function is a built-in function that cannot be modified.

• The 'main' function is only necessary for GUI applications.

• The 'main' function is the entry point for execution and organizes code for standalone or module use.
