Quiz: IT Fundamentals Module 01: Computers and Operating Systems (Module 01 of 06)

Which hardware component is often called the "brain" of the computer because it executes instructions and performs calculations?

What is the primary purpose of RAM (Random Access Memory) in a computer?

True or False: When you shut down a computer, the data stored in RAM is preserved.

Which of the following best describes the difference between an SSD and an HDD?

A computer has 16 GB of RAM and a 512 GB SSD. Which statement is correct?

What is the smallest unit of data a computer can store?

How many bits are in one byte?

Which of the following correctly orders data sizes from smallest to largest?

A high-resolution photo is approximately 5 MB. Approximately how many of these photos could you store on a 10 GB drive?

True or False: A bit can have one of two values: 0 or 1.

Which of the following is an example of something that is approximately 1 Terabyte (TB) in size?

In your own words, explain why understanding data sizes (KB, MB, GB, TB) matters in cloud computing.

What does an operating system do? (Select THREE.)Select multiple

Which of the following is NOT a function of an operating system?

True or False: An operating system sits between the hardware and the applications you run.

What is process management in the context of an operating system?

A user opens a web browser, a text editor, and a music player at the same time. Which OS function allows all three programs to share the CPU?

What is memory management in the context of an operating system?

What is the purpose of a device driver?

True or False: Without device drivers, the operating system would not know how to communicate with hardware devices like printers, keyboards, or network adapters.

Which three operating systems are the most commonly used today?

Which operating system is the dominant OS in cloud computing, running the majority of cloud servers, containers, and serverless environments?

Why does Linux dominate cloud computing? (Select THREE.)Select multiple

True or False: macOS is commonly used as a server operating system in cloud computing.

A company is choosing an operating system for its cloud servers. They want to minimize licensing costs, need a lightweight OS that runs without a graphical interface, and require long-term stability. Which OS best fits their requirements?

What is a file system?

In a Linux file system, what does the `/` symbol represent?

Which of the following is the correct path to a user's home directory on a Linux system?

In a Linux file system, what is the purpose of the `/etc/` directory?

True or False: Linux file systems are case-sensitive, meaning `File.txt` and `file.txt` are treated as two different files.

Which of the following is a key difference between Linux/macOS and Windows file systems?

Match the Linux directory to its purpose. Which TWO pairings are correct?

In your own words, describe the basic sequence of events that occurs when you open a program on your computer (from storage to CPU execution).

What is the role of the network interface in a computer?

True or False: An SSD is generally faster than an HDD because it has no moving parts and uses flash memory to read and write data.

A computer is running slowly when multiple programs are open. Which hardware component is most likely the bottleneck if the computer does not have enough temporary working space for all the running programs?

Which of the following statements about binary is correct?

How many bytes are in one Kilobyte (KB)?

A company needs to store 500 GB of data. Which of the following storage options provides enough capacity?

True or False: The operating system is responsible for managing both the graphical user interface (GUI) and the command-line interface (CLI).

Which of the following best describes the relationship between hardware and software?

A system administrator needs to check system configuration files on a Linux server. Which directory should they look in?

Which of the following is stored in the `/var/` directory on a Linux system?

A new IT employee is told: "Linux uses forward slashes and is case-sensitive. Windows uses backslashes and is case-insensitive." Which of the following file paths is valid on a Linux system?

True or False: In cloud computing, when you choose a virtual server (such as a cloud instance), you select the amount of CPU, RAM, and storage, the same hardware components found in a physical computer.

Which of the following scenarios best illustrates why Linux is preferred for cloud servers? (Select TWO.)Select multiple

What happens to data stored on an HDD or SSD when the computer is turned off?

A user saves a document to their computer and then shuts it down. The next day, they turn the computer back on and the document is still there. Which hardware component preserved the document?

True or False: Windows, macOS, and Linux are all examples of operating systems that manage hardware resources and provide services for applications.

In your own words, explain why Linux is the most important operating system to understand for someone pursuing a career in cloud computing. Include at least two reasons.
