Question 241.<\/b><\/p>\n

Which computer component is primarily responsible for providing short-term working memory for currently running applications?<\/b><\/p>\n

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

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

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

    RAM provides temporary working memory for the operating system, running applications, and active data. It is much faster than long-term storage and allows the CPU to access information quickly while programs are running. RAM is volatile, which means its contents are normally lost when power is removed. SSDs provide persistent storage, while power supplies and optical drives serve different hardware functions. Systems with more RAM can often keep more applications and data readily available without relying as heavily on slower virtual memory.<\/span><\/p>\n

    Question 242.<\/b><\/p>\n

    Which component stores files and applications even after the computer is powered off?<\/b><\/p>\n

      \n
    1. <\/b> CPU cache<\/span>
      \n<\/span>2.<\/b> SSD<\/span>
      \n<\/span>3.<\/b> RAM<\/span>
      \n<\/span>4.<\/b> Register<\/span><\/li>\n<\/ol>\n

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

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

      An SSD provides nonvolatile storage, so the information stored on it remains available after power is removed. Operating systems, applications, documents, and other files are commonly stored on SSDs. RAM, CPU cache, and processor registers are volatile memory technologies and are used primarily while the system is running. SSDs are generally faster than traditional mechanical hard drives because they do not rely on moving parts, making them popular for modern computers.<\/span><\/p>\n

      Question 243.<\/b><\/p>\n

      Which internal component provides slots and connectors for the CPU, memory, storage devices, and expansion cards?<\/b><\/p>\n

        \n
      1. <\/b> Cooling fan<\/span>
        \n<\/span>2.<\/b> Power supply<\/span>
        \n<\/span>3.<\/b> Motherboard<\/span>

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

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

        The motherboard is the primary circuit board inside a computer. It connects major components such as the CPU, memory, storage interfaces, expansion cards, firmware, and external ports. Different motherboards support different processor sockets, memory types, form factors, and expansion standards. The cooling fan removes heat, the power supply delivers electrical power, and the monitor provides visual output. Compatibility must therefore be considered when replacing or upgrading motherboard-connected components.<\/span><\/p>\n

        Question 244.<\/b><\/p>\n

        Which device converts electrical power from a wall outlet into voltages used by internal computer components?<\/b><\/p>\n

        1. <\/b> CPU<\/span>
          \n<\/span>2.<\/b> Motherboard<\/span>
          \n<\/span>3.<\/b> Heat sink<\/span>
          \n<\/span>4.<\/b> Power supply**<\/span><\/li>\n<\/ol>\n

          Correct Answer: 4. Power supply<\/b><\/p>\n

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

          A power supply unit converts incoming electrical power into regulated voltages required by internal computer components. It supplies power to the motherboard, processor, storage devices, graphics hardware, fans, and other components. The CPU processes instructions, the motherboard connects components, and a heat sink helps remove heat. A failing or inadequate power supply can cause instability, startup failures, random shutdowns, or other hardware problems.<\/span><\/p>\n

          Question 245.<\/b><\/p>\n

          Which display resolution contains more pixels than 1920 \u00d7 1080?<\/b><\/p>\n

            \n<\/span>2.<\/b> 1280 \u00d7 720<\/span>
            \n<\/span>3.<\/b> 1024 \u00d7 768<\/span>
            \n<\/span>4.<\/b> 800 \u00d7 600<\/span><\/li>\n<\/ol>\n

            Correct Answer: 1. 2560 \u00d7 1440<\/b><\/p>\n

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

            A 2560 \u00d7 1440 display contains more pixels than a 1920 \u00d7 1080 display, which can provide additional screen space and finer image detail when supported by the display and graphics hardware. The other listed resolutions contain fewer pixels. Higher resolution can improve image clarity but may also require more graphics-processing capability. Users may need to adjust operating-system scaling so text and interface elements remain comfortable to read.<\/span><\/p>\n

            Question 246.<\/b><\/p>\n

            Which metric describes how many times per second a display can update its image?<\/b><\/p>\n

              \n
            1. <\/b> Brightness<\/span>
              \n<\/span>2.<\/b> Refresh rate<\/span>
              \n<\/span>3.<\/b> Storage capacity<\/span>
              \n<\/span>4.<\/b> Color depth only<\/span><\/li>\n<\/ol>\n

              Correct Answer: 2. Refresh rate<\/b><\/p>\n

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

              Refresh rate describes how often a display updates its image each second and is measured in hertz. For example, a 60 Hz display can refresh up to 60 times per second. Higher refresh rates can make motion appear smoother, especially in gaming and other fast-moving visual content. Brightness describes light output, while storage capacity and color depth measure different characteristics. The actual experience also depends on the graphics system’s ability to produce frames at an appropriate rate.<\/span><\/p>\n

              Question 247.<\/b><\/p>\n

              Which component is primarily responsible for generating images sent to a display?<\/b><\/p>\n

                \n
              1. <\/b> RAM only<\/span>
                \n<\/span>2.<\/b> PSU<\/span>
                \n<\/span>3.<\/b> GPU<\/span>
                \n<\/span>4.<\/b> NIC<\/span><\/li>\n<\/ol>\n

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

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

                The graphics processing unit, or GPU, performs many calculations required to render images, video, animations, and 3D graphics. It then provides display output through supported interfaces. Some CPUs include integrated graphics, while higher-performance systems may use dedicated graphics cards. RAM supports applications, the PSU provides power, and the NIC provides network connectivity. GPUs can also accelerate certain non-graphics workloads that benefit from highly parallel processing.<\/span><\/p>\n

                Question 248.<\/b><\/p>\n

                Which connection is commonly used to transmit digital video and audio to a monitor or television?<\/b><\/p>\n

                  \n
                1. <\/b> RJ-11<\/span>
                  \n<\/span>2.<\/b> PS\/2<\/span>
                  \n<\/span>3.<\/b> SATA<\/span>
                  \n<\/span>4.<\/b> HDMI**<\/span><\/li>\n<\/ol>\n

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

                    \n<\/span>2.<\/b> Speaker<\/span>
                    \n<\/span>3.<\/b> Monitor<\/span>
                    \n<\/span>4.<\/b> Projector<\/span><\/li>\n<\/ol>\n

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

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

                    A microphone is an input device that captures sound and converts it into a signal the computer can process. It can be used for voice calls, recordings, speech recognition, gaming, and conferencing. Speakers provide audio output, while monitors and projectors provide visual output. Many laptops and mobile devices include built-in microphones, though external microphones may provide better quality for professional or specialized use.<\/span><\/p>\n

                    Question 250.<\/b><\/p>\n

                    Which peripheral primarily produces audio output?<\/b><\/p>\n

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

                      A speaker is an output device that converts electrical or digital audio signals into audible sound. Speakers are used for music, calls, notifications, videos, and other audio content. Microphones capture audio input, scanners capture documents, and webcams capture video. Some devices combine multiple input and output functions, such as headsets that include both headphones and a microphone.<\/span><\/p>\n

                      Question 251.<\/b><\/p>\n

                      Which device is primarily used to capture video input for conferencing or recording?<\/b><\/p>\n

                        \n
                      1. <\/b> Printer<\/span>
                        \n<\/span>2.<\/b> Speaker<\/span>

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

                        A webcam captures video and sends it to the computer for use in video calls, streaming, recording, or monitoring. Many webcams also include microphones, but their primary function is video input. Printers produce physical output, speakers produce audio output, and UPS devices provide temporary electrical power. Webcam performance may depend on resolution, frame rate, lighting, network bandwidth, and application settings.<\/span><\/p>\n

                        Question 252.<\/b><\/p>\n

                        Which device provides temporary power during an electrical outage so a computer can remain running briefly or shut down safely?<\/b><\/p>\n

                          \n
                        1. <\/b> Switch<\/span>

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

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

                          An uninterruptible power supply, or UPS, contains a battery that can provide temporary power when normal utility power fails. This can allow a computer to continue operating through a short outage or shut down safely during a longer one. A surge protector helps reduce damage from voltage spikes but usually does not provide battery backup. Routers and switches are network devices. UPS systems are especially valuable for servers and critical networking equipment.<\/span><\/p>\n

                          Question 253.<\/b><\/p>\n

                          Which type of network device forwards Ethernet frames primarily using destination MAC addresses?<\/b><\/p>\n

                            \n
                          1. <\/b> Switch<\/span>
                            \n<\/span>2.<\/b> Router<\/span>

                            \n<\/span>4.<\/b> Firewall only<\/span><\/li>\n<\/ol>\n

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

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

                            A switch forwards Ethernet frames within a LAN by learning which MAC addresses are associated with its ports. When a frame arrives, the switch can direct it toward the correct destination port rather than sending it everywhere. Routers forward packets between IP networks, while modems terminate certain service-provider connections. Firewalls enforce network-security policies. Switches are therefore fundamental components of wired local area networks.<\/span><\/p>\n

                            Question 254.<\/b><\/p>\n

                            Which network device primarily forwards packets between different IP networks?<\/b><\/p>\n

                              \n
                            1. <\/b> Hub<\/span>

                              \n<\/span>4.<\/b> Printer<\/span><\/li>\n<\/ol>\n

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

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

                              A router forwards IP packets between different networks using routing information and destination addresses. For example, a home router commonly forwards traffic between a private LAN and the internet. A hub operates at a lower layer and does not route IP traffic, while keyboards and printers are peripherals. Many modern home devices combine routing, switching, wireless access, firewall, and DHCP functions in one unit.<\/span><\/p>\n

                              Question 255.<\/b><\/p>\n

                              Which network service provides automatic IP addresses, default gateway information, and DNS settings to clients?<\/b><\/p>\n

                                \n
                              1. <\/b> HTTP<\/span>
                                \n<\/span>2.<\/b> SMTP<\/span>
                                \n<\/span>3.<\/b> DHCP<\/span>
                                \n<\/span>4.<\/b> FTP<\/span><\/li>\n<\/ol>\n

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

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

                                DHCP automatically provides clients with network configuration information such as IP addresses, subnet information, default gateways, and DNS server addresses. This makes network administration much easier than configuring every device manually. HTTP is used for web traffic, SMTP sends email, and FTP transfers files. When DHCP fails, a client may receive a link-local address and be unable to access normal network resources.<\/span><\/p>\n

                                Question 256.<\/b><\/p>\n

                                Which service converts domain names such as example.com into IP addresses?<\/b><\/p>\n

                                  \n
                                1. <\/b> DHCP<\/span>
                                  \n<\/span>2.<\/b> SSH<\/span>

                                  \n<\/span>4.<\/b> DNS**<\/span><\/li>\n<\/ol>\n

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

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

                                  DNS, or Domain Name System, translates human-readable names into IP addresses that computers use for network communication. Without DNS, users would often need to remember numerical addresses. DHCP provides network configuration, SSH provides secure remote access, and NTP synchronizes time. A DNS failure can make websites appear unavailable by name even when direct IP connectivity still functions.<\/span><\/p>\n

                                  Question 257.<\/b><\/p>\n

                                  Which protocol is commonly used to securely access websites?<\/b><\/p>\n

                                    \n
                                  1. <\/b> HTTPS<\/span>

                                    \n<\/span>3.<\/b> TFTP<\/span>
                                    \n<\/span>4.<\/b> FTP<\/span><\/li>\n<\/ol>\n

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

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

                                    HTTPS secures web traffic by using encryption, commonly TLS, between a browser and web server. This helps protect passwords, payment details, and other sensitive information from interception or modification in transit. Telnet is an insecure remote-access protocol, while FTP and TFTP are file-transfer protocols. HTTPS improves transport security, though users must still confirm that they are visiting the correct and trustworthy website.<\/span><\/p>\n

                                    Question 258.<\/b><\/p>\n

                                      \n<\/span>3.<\/b> FTP<\/span>
                                      \n<\/span>4.<\/b> SMTP<\/span><\/li>\n<\/ol>\n

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

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

                                      SSH, or Secure Shell, provides encrypted remote command-line access to systems such as servers and network devices. It protects authentication credentials and transmitted commands from easy interception. HTTP is used for web traffic, FTP for file transfers, and SMTP for email transmission. SSH is preferred over older insecure remote-access protocols such as Telnet when managing systems across networks.<\/span><\/p>\n

                                      Question 259.<\/b><\/p>\n

                                      Which security practice most directly protects an unattended workstation from casual unauthorized access?<\/b><\/p>\n

                                        \n
                                      1. <\/b> Disable updates<\/span>
                                        \n<\/span>2.<\/b> Share the password<\/span>
                                        \n<\/span>3.<\/b> Lock the screen<\/span>
                                        \n<\/span>4.<\/b> Lower the display brightness<\/span><\/li>\n<\/ol>\n

                                        Correct Answer: 3. Lock the screen<\/b><\/p>\n

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

                                        Locking the screen prevents another person from accessing an active user session without authentication. It is a simple but important security practice whenever a user steps away from a workstation. Sharing passwords and disabling updates weaken security, while adjusting brightness does not control access. Organizations often configure automatic screen locking after a period of inactivity to reduce the chance that unattended systems remain exposed.<\/span><\/p>\n

                                        Question 260.<\/b><\/p>\n

                                        A user reports that a wired computer suddenly has no network connection. Which troubleshooting action should be performed first?<\/b><\/p>\n

                                          \n
                                        1. <\/b> Replace the motherboard immediately<\/span>
                                          \n<\/span>2.<\/b> Reinstall the operating system<\/span>
                                          \n<\/span>3.<\/b> Reset every network device<\/span>
                                          \n<\/span>4.<\/b> Check the Ethernet cable and link status**<\/span><\/li>\n<\/ol>\n

                                          Correct Answer: 4. Check the Ethernet cable and link status<\/b><\/p>\n

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

                                          Basic physical connectivity should be checked early when a wired network connection suddenly fails. The technician should confirm that the Ethernet cable is securely connected, inspect the cable for damage, and check link indicators on the computer and switch. If physical connectivity appears normal, the investigation can proceed to IP configuration, DHCP, drivers, and other network settings. Replacing hardware or reinstalling the operating system before checking simple causes would be inefficient.<\/span><\/p>\n
