1.
Which part does 1 represent?
Correct Answer
D. Power Supply
Explanation
Number 1 in the diagram corresponds to the power supply, as it is located in the upper corner of the case, consistent with typical PSU placement. It is a key component that ensures all other parts of the computer receive the necessary power to operate.
2.
Which part does 2 represent?
Correct Answer
D. Video Card
Explanation
Number 2 corresponds to the Video Card (Graphics Card/GPU). This component is responsible for rendering images, videos, and animations to be displayed on your monitor. It's an essential part of any computer that needs to handle graphic-intensive tasks like gaming, video editing, or 3D rendering. The video card typically fits into one of the PCIe (Peripheral Component Interconnect Express) slots on the motherboard, as it does in your diagram.
3.
Which part does 3 represent?
Correct Answer
C. Sound Card
Explanation
Number 3 corresponds to the Sound Card. The sound card is an expansion card or integrated circuit that provides audio input and output capabilities to the computer. It allows you to connect speakers, microphones, and other audio devices to your computer. The sound card converts digital data into audio signals that can be heard through speakers or headphones.
4.
Which part does 4 represent?
Correct Answer
A. Modem
Explanation
Number 4 corresponds to the component located in another expansion slot, similar to the sound card and video card. This placement is consistent with how modems were typically installed in older systems. In modern systems, modems are often external devices connected via USB or Ethernet, or they are integrated into routers, so you might not find an internal modem in many current setups.
5.
Which part does 5 represent?
Correct Answer
B. Motherboard
Explanation
Number 5 corresponds to the motherboard. The motherboard is the main circuit board in a computer, connecting all of the components together. It hosts the CPU, RAM, and expansion slots (for video cards, sound cards, etc.), and provides connectors for storage devices, power supply, and peripherals. The entire background or base of the diagram likely represents the Motherboard. This includes all the slots and ports where other components (like the video card, sound card, modem, etc.) are installed.
6.
Which part does 6 represent?
Correct Answer
A. CD-ROM Drive
Explanation
Number 6 is positioned in the upper right area of the diagram, which aligns with where a CD-ROM drive would typically be located in a desktop computer case. The CD-ROM drive is used to read data from CDs, and in some cases, it may also be a DVD or Blu-ray drive, capable of reading and writing to CDs, DVDs, and Blu-ray discs. This drive allows users to install software, play media, and access other data stored on optical discs.
7.
Which part does 7 represent?
Correct Answer
C. Hard Drive
Explanation
Number 7 corresponds to the Hard Drive in the diagram, especially if it's located in a drive bay within the lower section of the case. The hard drive is usually found in a drive bay located in the lower to middle section of the computer case, often towards the front. This placement is common in both traditional desktop towers and other computer configurations. The hard drive is responsible for storing the computer’s operating system, software, and personal files. It is a crucial component for data storage, whether in the form of a traditional spinning hard disk drive (HDD) or a solid-state drive (SSD).
8.
Which part does 8 represent?
Correct Answer
B. Floppy Disk Drive
Explanation
Number 8 is the floppy disk drive, especially if it is positioned near the front and in a smaller bay compared to other drives like the CD-ROM drive. The floppy drive is used for reading and writing to floppy disks, which were common for data storage and transfer before the advent of CDs, USB drives, and other modern storage solutions. While floppy drives are largely obsolete today, they were a standard feature in older computers.
9.
Which part does 9 represent?
Correct Answer
D. RAM
Explanation
Number 9 corresponds to the RAM, which is located in the dedicated slots on the motherboard, often close to the CPU. RAM is the memory used by your computer to store data temporarily while it's running. It allows the CPU to access data much faster than from the hard drive or other storage devices, making it crucial for multitasking and the overall speed of the computer.
10.
Which part does 10 represent?
Correct Answer
B. CPU
Explanation
Number 10 corresponds to the CPU, which is housed in a socket on the motherboard. The CPU is often covered by a heatsink and fan to manage its temperature, as it generates significant heat during operation. The CPU is the brain of the computer, responsible for executing instructions from programs and processing data. It performs the calculations and operations necessary to run software, manage system resources, and handle user commands.
11.
Which part does 11 represent?
Correct Answer
A. BIOS
Explanation
Number 11 corresponds to the BIOS chip, which is integral to starting up the computer and managing the initial hardware configuration. The BIOS is firmware stored on a small memory chip on the motherboard. It initializes and tests the system hardware components while booting up the computer and provides runtime services for the operating system and programs. The BIOS also includes a setup utility, allowing users to configure hardware settings, such as boot order and system time.
