Question 1<\/b><\/h3>\n

Which component is primarily responsible for performing arithmetic and logical operations in a computer?<\/b><\/p>\n

    \n
  1. CPU<\/span><\/li>\n
  2. RAM<\/span><\/li>\n
  3. SSD<\/span><\/li>\n
  4. Power supply<\/span><\/li>\n<\/ol>\n

    Correct Answer: 1<\/b><\/p>\n

    Explanation<\/b><\/p>\n

    The Central Processing Unit (CPU) performs arithmetic, logical, control, and other processing operations required to execute instructions. It contains components such as the arithmetic logic unit and control unit that work together to process data and instructions. RAM temporarily stores information that the CPU is actively using, while an SSD provides persistent storage. The power supply converts electrical power into suitable voltages for system components but does not perform computational operations. Therefore, the CPU is the primary component responsible for executing calculations and processing instructions.<\/span><\/p>\n

    Question 2<\/b><\/h3>\n

    A technician needs to install additional memory in a desktop computer. Which specification should be checked first to ensure the new memory is compatible with the motherboard?<\/b><\/p>\n

      \n
    1. Monitor resolution<\/span><\/li>\n
    2. RAM type and supported capacity<\/span><\/li>\n
    3. Keyboard interface<\/span><\/li>\n
    4. Printer speed<\/span><\/li>\n<\/ol>\n

      Correct Answer: 2<\/b><\/p>\n

      Explanation<\/b><\/p>\n

      Before installing additional memory, the technician should verify the RAM type and the maximum memory capacity supported by the motherboard. Different generations of memory, such as DDR4 and DDR5, use different electrical characteristics and physical designs and are generally not interchangeable. The motherboard may also have limits on total supported capacity and individual module sizes. Monitor resolution, keyboard interface, and printer speed have no direct relationship to system memory compatibility. Checking the motherboard specifications prevents installing incompatible modules or exceeding supported memory limits.<\/span><\/p>\n

      Question 3<\/b><\/h3>\n

      Which storage technology generally provides faster access times and better resistance to physical shock than a traditional hard disk drive?<\/b><\/p>\n

        \n
      1. Optical disc<\/span><\/li>\n
      2. Magnetic tape<\/span><\/li>\n
      3. Solid-state drive<\/span><\/li>\n
      4. Floppy disk<\/span><\/li>\n<\/ol>\n

        Correct Answer: 3<\/b><\/p>\n

        Explanation<\/b><\/p>\n

        A solid-state drive (SSD) stores data using flash memory and has no moving mechanical components. This allows SSDs to provide significantly faster access times than traditional hard disk drives, which rely on spinning platters and moving read\/write heads. The lack of moving parts also makes SSDs more resistant to physical shock and vibration. Optical discs, magnetic tape, and floppy disks use different storage technologies and generally provide much lower performance. SSDs are therefore widely used when fast storage performance, durability, and quick system response are important.<\/span><\/p>\n

        Question 4<\/b><\/h3>\n

        Which connector is commonly used to provide both digital video and audio from a computer to a television or monitor?<\/b><\/p>\n

          \n
        1. PS\/2<\/span><\/li>\n
        2. RJ45<\/span><\/li>\n
        3. USB-A<\/span><\/li>\n
        4. HDMI<\/span><\/li>\n<\/ol>\n

          Correct Answer: 4<\/b><\/p>\n

          Explanation<\/b><\/p>\n

          HDMI is a digital interface commonly used to transmit both high-definition video and digital audio through a single cable. It is frequently found on computers, televisions, monitors, projectors, and home theater equipment. PS\/2 connectors are primarily associated with older keyboards and mice, while RJ45 connectors are commonly used for Ethernet networking. USB-A is a general-purpose peripheral connector and can support many devices, but it is not the traditional dedicated interface for connecting a computer directly to a display with audio. HDMI is therefore the appropriate choice.<\/span><\/p>\n

          Question 5<\/b><\/h3>\n

          A user reports that a desktop computer shuts down unexpectedly when running demanding applications. Which component should a technician inspect first for insufficient capacity or failure?<\/b><\/p>\n

            \n
          1. Power supply<\/span><\/li>\n
          2. Keyboard<\/span><\/li>\n
          3. Optical drive<\/span><\/li>\n
          4. Webcam<\/span><\/li>\n<\/ol>\n

            Correct Answer: 1<\/b><\/p>\n

            Explanation<\/b><\/p>\n

            Unexpected shutdowns during demanding workloads can indicate that the power supply is unable to provide sufficient stable power to the system. High-performance processors and graphics cards can significantly increase power consumption when operating under heavy loads. A failing or undersized power supply may cause instability, shutdowns, or rebooting when demand increases. Although overheating can produce similar symptoms, the power supply should be considered when the problem specifically occurs as system power requirements increase. Keyboard, optical drive, and webcam problems would not normally cause this type of system-wide shutdown.<\/span><\/p>\n

            Question 6<\/b><\/h3>\n

            Which memory characteristic determines the amount of data that a RAM module can store?<\/b><\/p>\n

              \n
            1. Clock speed<\/span><\/li>\n
            2. Capacity<\/span><\/li>\n
            3. CAS latency<\/span><\/li>\n
            4. Channel configuration<\/span><\/li>\n<\/ol>\n

              Correct Answer: 2<\/b><\/p>\n

              Explanation<\/b><\/p>\n

              Memory capacity describes the total amount of data that a RAM module can hold, commonly measured in gigabytes (GB). For example, an 8 GB module can store twice as much data as a 4 GB module under the same conditions. Clock speed describes the rate at which memory operates, while CAS latency represents the delay between a memory request and the availability of data. Channel configuration describes how memory modules communicate with the memory controller. These characteristics affect performance, but capacity specifically determines how much information the RAM can store.<\/span><\/p>\n

              Question 7<\/b><\/h3>\n

              Which CPU feature allows a processor to execute instructions from multiple threads concurrently?<\/b><\/p>\n

                \n
              1. Hyper-threading or simultaneous multithreading<\/span><\/li>\n
              2. ECC memory<\/span><\/li>\n
              3. RAID<\/span><\/li>\n
              4. Virtual memory<\/span><\/li>\n<\/ol>\n

                Correct Answer: 1<\/b><\/p>\n

                Explanation<\/b><\/p>\n

                Hyper-threading, or simultaneous multithreading on supported processors, allows a physical CPU core to handle multiple instruction threads concurrently. This can improve processor utilization and performance when applications are designed to benefit from multiple threads. ECC is a memory technology designed to detect and correct certain memory errors. RAID combines storage devices to provide performance, redundancy, or both. Virtual memory uses storage space to supplement physical RAM. These technologies serve different purposes and do not provide the CPU multithreading capability described in the question.<\/span><\/p>\n

                Question 8<\/b><\/h3>\n

                Which port is most commonly associated with wired Ethernet networking on a desktop computer?<\/b><\/p>\n

                  \n
                1. HDMI<\/span><\/li>\n
                2. RJ45<\/span><\/li>\n
                3. DisplayPort<\/span><\/li>\n
                4. 3.5 mm audio<\/span><\/li>\n<\/ol>\n

                  Correct Answer: 2<\/b><\/p>\n

                  Explanation<\/b><\/p>\n

                  An RJ45-style Ethernet port is commonly used to connect a computer to a wired network using twisted-pair Ethernet cabling. The connector is typically found on desktop computers, laptops, switches, routers, and other networking equipment. HDMI and DisplayPort are primarily used for digital video and, depending on the interface, audio transmission. A 3.5 mm connector is generally used for analog audio devices such as headphones, microphones, and speakers. Therefore, RJ45 is the appropriate connector when establishing a conventional wired Ethernet connection.<\/span><\/p>\n

                  Question 9<\/b><\/h3>\n

                  Which type of firmware is commonly stored on a motherboard and initializes hardware before the operating system loads?<\/b><\/p>\n

                    \n
                  1. BIOS or UEFI<\/span><\/li>\n
                  2. Application software<\/span><\/li>\n
                  3. Device driver<\/span><\/li>\n
                  4. Word processor<\/span><\/li>\n<\/ol>\n

                    Correct Answer: 1<\/b><\/p>\n

                    Explanation<\/b><\/p>\n

                    BIOS and UEFI are motherboard firmware technologies responsible for initializing and testing hardware during the startup process before handing control to the operating system. UEFI is the modern successor to traditional BIOS and provides additional capabilities, including support for modern boot methods and larger storage devices. A device driver allows an operating system to communicate with hardware after the operating system has loaded. Application software performs user-oriented tasks, while a word processor is a specific type of application. Therefore, BIOS or UEFI performs the required pre-boot hardware initialization.<\/span><\/p>\n

                    Question 10<\/b><\/h3>\n

                    A laptop user wants to connect a wireless headset without using a cable. Which technology is most appropriate?<\/b><\/p>\n

                      \n
                    1. SATA<\/span><\/li>\n
                    2. Bluetooth<\/span><\/li>\n
                    3. VGA<\/span><\/li>\n
                    4. Ethernet<\/span><\/li>\n<\/ol>\n

                      Correct Answer: 2<\/b><\/p>\n

                      Explanation<\/b><\/p>\n

                      Bluetooth is a short-range wireless technology commonly used to connect peripherals such as headsets, keyboards, mice, speakers, and smartphones. A Bluetooth headset can communicate wirelessly with a compatible laptop without requiring a physical audio cable. SATA is primarily an internal storage interface, while VGA is an older analog video interface. Ethernet provides wired network connectivity through a physical cable. Bluetooth is therefore the appropriate technology for connecting a wireless headset when the laptop and headset support compatible Bluetooth functionality.<\/span><\/p>\n

                      Question 11<\/b><\/h3>\n

                      Which device is primarily used to convert AC power from a wall outlet into the DC voltages required by internal computer components?<\/b><\/p>\n

                        \n
                      1. Network switch<\/span><\/li>\n
                      2. Power supply unit<\/span><\/li>\n
                      3. Heat sink<\/span><\/li>\n
                      4. Motherboard chipset<\/span><\/li>\n<\/ol>\n

                        Correct Answer: 2<\/b><\/p>\n

                        Explanation<\/b><\/p>\n

                        A power supply unit (PSU) converts alternating current from an electrical outlet into the direct-current voltages required by components such as the motherboard, CPU, storage devices, and graphics hardware. The PSU also distributes power through appropriate connectors and provides protections against certain electrical conditions. A network switch connects network devices, a heat sink removes heat from components, and a motherboard chipset manages communication between selected system components. Because its primary purpose is electrical power conversion and distribution, the PSU is the correct answer.<\/span><\/p>\n

                        Question 12<\/b><\/h3>\n

                        Which display technology uses individual pixels that emit their own light without requiring a separate backlight?<\/b><\/p>\n

                          \n
                        1. OLED<\/span><\/li>\n
                        2. LCD<\/span><\/li>\n
                        3. CRT<\/span><\/li>\n
                        4. Projector<\/span><\/li>\n<\/ol>\n

                          Correct Answer: 1<\/b><\/p>\n

                          Explanation<\/b><\/p>\n

                          OLED displays use organic light-emitting diodes in which individual pixels generate their own light. Because each pixel can be independently controlled, OLED technology can produce deep blacks and high contrast without requiring a separate backlight. Traditional LCD displays generally rely on a backlight that passes through liquid crystal elements to produce the image. CRT displays use electron beams and phosphors, while projectors use separate light sources and optical systems to project an image. OLED is therefore the display technology described in the question.<\/span><\/p>\n

                          Question 13<\/b><\/h3>\n

                          A technician wants to protect a computer from static electricity while replacing internal components. Which item should be used?<\/b><\/p>\n

                            \n
                          1. Thermal paste<\/span><\/li>\n
                          2. Cable tester<\/span><\/li>\n
                          3. Antistatic wrist strap<\/span><\/li>\n
                          4. Loopback plug<\/span><\/li>\n<\/ol>\n

                            Correct Answer: 3<\/b><\/p>\n

                            Explanation<\/b><\/p>\n

                            An antistatic wrist strap helps safely discharge electrostatic electricity from the technician while working with sensitive computer components. Electrostatic discharge can damage semiconductor components such as RAM, CPUs, motherboards, and expansion cards even when the damage is not immediately visible. Thermal paste is used to improve heat transfer between a processor and its cooling solution. A cable tester checks cable connectivity, while a loopback plug is used for certain diagnostic testing. Proper ESD protection is therefore essential when handling internal computer hardware.<\/span><\/p>\n

                            Question 14<\/b><\/h3>\n

                            Which interface is commonly used to connect an internal 2.5-inch SATA SSD to a compatible motherboard?<\/b><\/p>\n

                              \n
                            1. SATA<\/span><\/li>\n
                            2. HDMI<\/span><\/li>\n
                            3. Bluetooth<\/span><\/li>\n
                            4. RJ11<\/span><\/li>\n<\/ol>\n

                              Correct Answer: 1<\/b><\/p>\n

                              Explanation<\/b><\/p>\n

                              SATA is a common interface for connecting internal storage devices such as SATA SSDs and traditional SATA hard drives to a compatible motherboard. A SATA data cable connects the drive to the motherboard, while a separate power connection supplies electrical power to the drive. HDMI is primarily a display interface, Bluetooth provides short-range wireless communication, and RJ11 is commonly associated with telephone connections. Therefore, SATA is the appropriate interface for connecting a conventional internal SATA SSD to a motherboard.<\/span><\/p>\n

                              Question 15<\/b><\/h3>\n

                              Which RAID level provides disk mirroring by maintaining an identical copy of data on two drives?<\/b><\/p>\n

                                \n
                              1. RAID 0<\/span><\/li>\n
                              2. RAID 5<\/span><\/li>\n
                              3. RAID 1<\/span><\/li>\n
                              4. RAID 10 only<\/span><\/li>\n<\/ol>\n

                                Correct Answer: 3<\/b><\/p>\n

                                Explanation<\/b><\/p>\n

                                RAID 1 provides disk mirroring by writing the same data to two drives. If one drive fails, the mirrored copy on the other drive can continue providing access to the stored information. RAID 0 uses striping without providing redundancy, while RAID 5 uses striping with distributed parity and requires multiple drives. RAID 10 combines mirroring and striping and requires a larger number of drives. RAID 1 is therefore the RAID level specifically associated with straightforward two-drive mirroring.<\/span><\/p>\n

                                Question 16<\/b><\/h3>\n

                                A technician needs to troubleshoot a computer that has no video output. The system powers on and the monitor is known to work. Which action should be performed next?<\/b><\/p>\n

                                  \n
                                1. Replace the keyboard<\/span><\/li>\n
                                2. Check the video cable and display connection<\/span><\/li>\n
                                3. Format the storage drive<\/span><\/li>\n
                                4. Replace the printer<\/span><\/li>\n<\/ol>\n

                                  Correct Answer: 2<\/b><\/p>\n

                                  Explanation<\/b><\/p>\n

                                  When a computer powers on but produces no video, the technician should first verify the physical display connection, including the video cable, correct input source, and connection to the appropriate graphics output. Simple physical or configuration issues can cause a no-display condition without indicating a major hardware failure. Formatting the storage drive would not normally resolve a basic video-output problem, and replacing unrelated peripherals such as a keyboard or printer is unnecessary. Starting with physical connections follows a logical troubleshooting process and avoids replacing components without sufficient evidence.<\/span><\/p>\n

                                  Question 17<\/b><\/h3>\n

                                  Which connector is commonly used for analog headphones or speakers on a personal computer?<\/b><\/p>\n

                                  3. 3.5 mm audio connector<\/span><\/li>\n
                                  4. SATA<\/span><\/li>\n<\/ol>\n

                                    Correct Answer: 3<\/b><\/p>\n

                                    Explanation<\/b><\/p>\n

                                    A 3.5 mm audio connector is commonly used for analog headphones, speakers, and microphones on personal computers. Desktop systems may provide separate ports for line-out, microphone input, and other audio functions. RJ45 is associated with Ethernet networking, DisplayPort is primarily a digital display interface, and SATA connects internal storage devices. Although modern computers increasingly support USB and wireless audio devices, the 3.5 mm connector remains a common physical interface for analog audio equipment. Therefore, the 3.5 mm audio connector is the appropriate choice.<\/span><\/p>\n

                                    Question 18<\/b><\/h3>\n

                                    Which troubleshooting step should generally be performed before replacing a suspected failed hardware component?<\/b><\/p>\n

                                      \n
                                    1. Verify the problem and gather information<\/span><\/li>\n

                                      Correct Answer: 1<\/b><\/p>\n

                                      Explanation<\/b><\/p>\n

                                      A technician should first identify and verify the problem before replacing hardware. Gathering information about symptoms, recent changes, error messages, and environmental conditions helps establish a clear problem description. The technician can then develop and test a likely cause rather than replacing components based on assumptions. Deleting user files, replacing every cable, or reinstalling every application can create additional problems and wastes time when the actual cause may be unrelated. A methodical troubleshooting process reduces unnecessary component replacement and helps produce a reliable solution.<\/span><\/p>\n

                                        Correct Answer: 2<\/b><\/p>\n

                                        Explanation<\/b><\/p>\n

                                        The Graphics Processing Unit (GPU) is designed to perform highly parallel calculations required for rendering images, video, and other graphics-intensive workloads. A dedicated GPU can significantly accelerate applications such as gaming, 3D modeling, video production, and certain computational workloads. RAM provides temporary system memory, the PSU supplies electrical power, and a Network Interface Card provides network connectivity. While the CPU can also perform graphics-related calculations, the GPU is specifically optimized for large numbers of parallel operations associated with graphics processing.<\/span><\/p>\n

                                        3. Verify full system functionality and document the results<\/span><\/li>\n
                                        4. Disable system security controls<\/span><\/li>\n<\/ol>\n

                                          Correct Answer: 3<\/b><\/p>\n

                                          Explanation<\/b><\/p>\n

                                          After completing a repair, the technician should verify that the original problem has been resolved and that the system’s relevant functions operate correctly. Testing may include restarting the computer, checking affected hardware, running appropriate diagnostics, and confirming that normal user functionality has been restored. The technician should then document the troubleshooting steps, repair performed, and verification results. Closing the ticket without testing can leave unresolved problems, while removing working components or disabling security controls introduces unnecessary risk. Proper verification and documentation complete the troubleshooting process.<\/span><\/p>\n
