What is volatile memory
Correct Answer
E. Both 2 and 3
Explanation
Volatile memory refers to a type of computer memory that requires power to retain stored data. It is non-permanent and loses its data when the power is turned off or disrupted. ROM (Read-Only Memory) is a type of non-volatile memory that retains data even without power. On the other hand, RAM (Random Access Memory) is a type of volatile memory that requires power to function and stores data temporarily while the computer is running. Therefore, the correct answer is both 2 (RAM) and 3 (needs power to work).
2.
The hard drive is
Correct Answer
B. Non-volatile
Explanation
A hard drive is considered non-volatile because it retains data even when the power is turned off. Unlike volatile storage devices such as RAM, which lose all data when power is lost, a hard drive uses magnetic or flash memory to permanently store data. This allows for long-term storage of files and programs, making it an essential component of a computer system.
3.
The operating system is stored in the
Correct Answer
C. Hard drive
Explanation
The operating system is stored in the hard drive. The hard drive is a non-volatile storage device that retains data even when the computer is turned off. It is where all the files and software, including the operating system, are stored for long-term use. The CPU and motherboard are essential components of a computer, but they do not store the operating system. The CPU is responsible for executing instructions, and the motherboard connects all the components of the computer. However, the operating system is primarily stored in the hard drive for easy access and retrieval.

When checking the status of the internet on a MAC computer the
Correct Answer
A. Yellow means not connected
Explanation
The correct answer is that yellow means not connected. This means that when checking the status of the internet on a MAC computer, if the color indicator is yellow, it indicates that there is no connection to the internet.
5.
Speakers are an example of an
Correct Answer
B. Output device
Explanation
Speakers are an example of an output device because they are used to produce sound or audio output from a computer or electronic device. They receive electrical signals from the device and convert them into audible sound waves that can be heard by the user. Output devices are used to display or present information to the user, and in the case of speakers, they provide audio output for listening to music, watching videos, or hearing system sounds.
6.
The hardware that is responsible for processing information and processing instructions given to it is
Correct Answer
B. The CPU
Explanation
The CPU, or Central Processing Unit, is the hardware component responsible for processing information and executing instructions in a computer system. It is often referred to as the "brain" of the computer, as it performs all the necessary calculations and operations required for the system to function. The motherboard is a circuit board that connects various components of the computer, including the CPU, but it does not directly process information. The hard drive, on the other hand, is a storage device used for long-term data storage, and it does not handle processing instructions. Therefore, the correct answer is the CPU.
7.
Controls all of the hardware and software on a computer
Correct Answer
A. CPU
Explanation
The CPU (Central Processing Unit) is responsible for controlling all of the hardware and software on a computer. It is often referred to as the "brain" of the computer because it carries out instructions and performs calculations. The CPU is responsible for executing the instructions of the operating system and managing the hardware components, such as memory, storage, and input/output devices. Without the CPU, the computer would not be able to function properly and carry out tasks.
8.
Linux is
Correct Answer
A. Open source
Explanation
Linux is an open source operating system, meaning that its source code is freely available and can be modified and distributed by anyone. This openness allows users to customize and adapt Linux to their specific needs, making it highly flexible and customizable. Additionally, Linux is a cross-platform operating system, meaning it can run on various hardware architectures and is not limited to a specific type of computer. While some may argue that Linux is not as user-friendly as other operating systems, its open source nature allows for a wide range of user interfaces and distributions that cater to different levels of user experience.
