Trivia Quiz On Computer And Its Parts!

Explanation
The correct name for this part of a PC/Workstation is the system unit. The system unit is the main component of a computer that houses the motherboard, CPU, memory, and other essential hardware components. It is responsible for providing power, storage, and connectivity to all the other components of the computer. The system unit is typically a large rectangular box-like structure that holds all the internal components of the computer.

Explanation
The correct name for the part of a PC referred to in the question is CPU, which stands for Central Processing Unit. The CPU is the primary component responsible for executing instructions and performing calculations in a computer system. It acts as the brain of the computer, processing data and controlling the overall operation of the system.

Explanation
RAM, or Random Access Memory, is the correct name for this part of a PC. RAM is a type of computer memory that is used to store data that is being actively used by the computer's operating system, software applications, and processes. It is a volatile memory, meaning that its contents are lost when the computer is turned off or restarted. RAM plays a crucial role in the overall performance of a computer, as it allows for faster access to data compared to other types of storage devices like hard drives or solid-state drives.

Explanation
The correct name for this part of a PC/Workstation is a mouse. The mouse is a peripheral device that allows the user to control the cursor on the screen by moving it around on a flat surface. It typically has two or more buttons that can be clicked to perform various actions. The term "cursor" refers to the graphical representation of the mouse pointer on the screen, not the physical device itself.

Explanation
The correct name for this part of a PC/Workstation is a monitor. A monitor is a display device that visually presents information generated by the computer's graphics card. It allows users to view images, videos, and other visual content. A graphics card, on the other hand, is a separate component inside a PC/Workstation that is responsible for rendering and displaying images on the monitor. TV and speaker are unrelated to this specific part of a PC/Workstation.

Explanation
The correct name for this device is a USB stick, also commonly known as a pen drive. It is a portable storage device that uses flash memory to store and transfer data. It is often used to conveniently carry and transfer files between computers.

Explanation
This device is called a printer as it is used to produce hard copies of documents or images from a computer or other digital devices. It works by transferring text or graphics onto paper using ink or toner. Printers are commonly used in offices, homes, and various industries for printing documents, photos, and other visual materials. They come in different types such as inkjet printers, laser printers, and 3D printers, each with its own method of printing and capabilities.

Explanation
The correct answer is "Hard disk drive." A hard disk drive is a component of a computer that is used for long-term storage of data. It consists of one or more spinning disks, which are coated with a magnetic material, and a read/write head that can access and modify the data on the disks. Unlike floppy disk drives, DVD drives, and pen drives, which are used for portable storage, a hard disk drive is typically installed inside the computer case and provides much larger storage capacity.

Explanation
The correct name for the part of a PC described in the question is a DVD drive. A DVD drive is a device that allows a computer to read and write data to DVDs. It is a common component found in desktop and laptop computers, and it is used for various purposes such as playing DVDs, installing software, and burning data onto DVDs.

Explanation
The power supply unit is a vital component inside a PC as it provides electrical power to all the other components. Without a power supply unit, the PC would not be able to function as it needs a steady supply of power to operate. The power supply unit converts the AC power from the wall outlet into DC power that is required by the PC's components. It also regulates the voltage and current to ensure that the components receive the appropriate amount of power. Overall, the power supply unit is essential for the proper functioning of a PC.

Explanation
The motherboard is the main circuit board of a computer and is responsible for controlling many aspects of the PC. It houses the CPU, memory, and other essential components, and provides connections for various peripherals and expansion cards. It acts as a central hub, allowing communication between different hardware components and facilitating the smooth operation of the computer system.

Explanation
A webcam is a device that is useful for communicating with others over the Internet. It allows users to transmit live video and audio in real-time, making it an essential tool for video conferencing, online meetings, and live streaming. With a webcam, users can see and interact with others remotely, making it an effective communication device for both personal and professional use.

Explanation
The given answer is false because CPU stands for Central Processing Unit, not Computer Professional Unit. The CPU is the primary component of a computer that performs most of the processing inside the computer, including executing instructions, performing calculations, and managing data flow between different parts of the computer.

Explanation
The CPU, or Central Processing Unit, is often referred to as the "brains" of the computer because it is responsible for executing instructions, performing calculations, and controlling the overall operation of the computer system. It is the main component that carries out the majority of the processing tasks, making it a vital part of the computer's functionality.

Explanation
RAM (Random Access Memory) is a type of computer memory that is used to temporarily store data and instructions that the computer is actively using. It is a volatile memory, meaning that its contents are lost when the computer is powered off. While RAM is an essential component for running programs and applications, it is not where you store your work permanently. Documents and presentations are typically stored on a hard drive or other storage devices like solid-state drives or cloud storage. Therefore, the statement that RAM is where you store your work is false.

Explanation
Hard drives are slower but cheaper than solid state drives (SSDs). This statement is true because hard drives use mechanical components to read and write data, which makes them slower compared to SSDs that use flash memory. However, hard drives are generally more affordable than SSDs, making them a popular choice for storing large amounts of data where speed is not a critical factor.

Explanation
Expansion slots are a feature found on motherboards that allow users to add additional hardware components to their computer. These slots provide the ability to upgrade a computer by adding new devices such as graphics cards, sound cards, or network cards. By inserting these expansion cards into the slots, users can enhance the performance and functionality of their computer system. Therefore, the statement that expansion slots can be used to upgrade a computer is true.
