What holds permanent instructions that cannot be changed.Contains basic start up information.Checks OS prior to loading .
Correct Answer
C. ROM
Explanation
ROM stands for Read-Only Memory and it holds permanent instructions that cannot be changed. It contains basic start-up information and checks the operating system (OS) prior to loading. Unlike RAM (Random Access Memory) which can be read from and written to, ROM is non-volatile and retains its data even when the computer is turned off. Therefore, ROM is the correct answer for this question.
4.
The printed circuit board on which the CPU, RAM modules and other electronic circuit elements of a computer are installed on is called the ?
Correct Answer
C. Mother Board
Explanation
The correct answer is Mother Board. The motherboard is the main circuit board of a computer that houses the CPU, RAM modules, and other electronic circuit elements. It provides connections for all the other components and allows them to communicate with each other. The motherboard is essential for the computer to function properly as it acts as the central hub for all the hardware components.
5.
The motherboard’s battery is used for low-level system functions like storing a computer’s login settings.
Correct Answer
B. False
Explanation
The motherboard's battery is not used for storing a computer's login settings. Instead, it is used to provide power to the CMOS (Complementary Metal-Oxide-Semiconductor) chip, which is responsible for storing the computer's BIOS (Basic Input/Output System) settings. These settings include information about the hardware configuration, date, and time, but not login settings. Therefore, the statement is false.
6.
An MP3/IPod would be considered what kind of device?
Correct Answer
D. Input
Explanation
An MP3/iPod would be considered an input device because it is used to input audio files into a computer or other device. It allows the user to transfer and play music or other audio files from the device to a computer or other storage device.
7.
This device is a Network Interface Card
Correct Answer
B. False
Explanation
The given statement is "This device is a Network Interface Card" and the correct answer is "False". This means that the device in question is not a Network Interface Card.
8.
What devices are examples of Optical Storage
Correct Answer(s)
B. CD-R
D. BD-R
Explanation
CD-R and BD-R are examples of optical storage devices because they use laser technology to read and write data on optical discs. CD-R (Compact Disc-Recordable) is a type of optical disc that can be written to once and then read multiple times. BD-R (Blu-ray Disc-Recordable) is a high-capacity optical disc format that can store large amounts of data, such as high-definition video. Both CD-R and BD-R rely on the reflection and refraction of laser beams to read and write data, making them examples of optical storage devices.
9.
An open source operating system used primarily for handheld devices
Correct Answer
C. Android
Explanation
Android is an open source operating system primarily used for handheld devices. It was developed by Google and is known for its flexibility, customization options, and wide range of available apps. Android is used by various manufacturers and is compatible with different types of devices, including smartphones, tablets, and smartwatches. It offers a user-friendly interface and provides a seamless experience for users with its efficient performance and regular updates.

CNC stands for cellular network communication
Correct Answer
B. False
Explanation
The correct answer is False because CNC stands for Computer Numerical Control, not cellular network communication. CNC is a manufacturing process that involves the use of computers to control machine tools. It is commonly used in industries such as automotive, aerospace, and electronics for precision machining.

A VR Headset would be best categorised as
Correct Answer
A. An Output Device
Explanation
A VR headset is best categorized as an output device because it primarily provides visual and auditory output to the user. It displays virtual reality content through its built-in screens and speakers, allowing the user to experience a virtual environment. While some VR headsets may also have input capabilities such as motion tracking or hand controllers, their primary function is to deliver output to the user's senses. Therefore, classifying a VR headset as an output device is the most appropriate categorization.

What are the four (4) categories of components in a computer system
Correct Answer(s)
A. Input
C. Processing - System
E. Storage
J. Output
Explanation
The four categories of components in a computer system are input, output, processing - system, and storage. Input components include the keyboard and any other devices used to input data into the computer. Output components include the visual display unit and any other devices used to display or output information from the computer. Processing - system components refer to the central processing unit (CPU) and other components responsible for processing and executing instructions. Lastly, storage components include devices such as RAM and optical drives, which are used to store and retrieve data in the computer system.

A Portable Game Console uses what category of Operating System?
Correct Answer
C. Mobile
Explanation
A portable game console uses a mobile operating system. This is because a mobile operating system is designed to run on smaller, handheld devices such as smartphones and tablets, which are similar in size and functionality to portable game consoles. Mobile operating systems are optimized for touchscreens, have a wide range of apps and games available, and offer features such as wireless connectivity, multimedia capabilities, and efficient power management, all of which are essential for a portable gaming experience.
15.
Which of the following hardware components is least necessary in order for a computer to function?
Correct Answer
B. HDD
Explanation
The CPU (Central Processing Unit), RAM (Random Access Memory), and motherboard are all essential hardware components for a computer to function properly. The CPU is responsible for executing instructions, RAM provides temporary storage for data and programs, and the motherboard connects and allows communication between all the other components. On the other hand, the HDD (Hard Disk Drive) is not necessary for a computer to function, as it is primarily used for long-term storage of data. A computer can still operate without an HDD, using alternative storage options like solid-state drives or cloud storage.
