The correct answer is D. Power supply wattage rating.

The power supply wattage rating is the most important factor to consider before building a gaming computer, as it determines how much power the system can draw from the wall and how much power the components can consume. A power supply with a low wattage rating may not be able to support the high-end graphics card, processor, and other devices, resulting in poor performance, instability, or damage12.

To find the optimal power supply wattage rating for a gaming computer, the technician should calculate the total power consumption of all the components and add some headroom for future upgrades or overclocking. The technician can use online calculators such as Cooler Master Power Calculator or Seasonic Wattage Calculator to estimate the power requirements of the system3.

Running the printer’s alignment process is the first step that a technician should do to fix the shadowing problem on the printouts. Shadowing is a print quality issue that occurs when the printer prints a faint duplicate image of the original text or graphics, usually slightly offset from the original position. This can be caused by a misalignment of the printhead, which is the part of the printer that sprays ink onto the paper. The printer’s alignment process is a procedure that adjusts the position and angle of the printhead to ensure that the ink is applied accurately and evenly on the paper. The printer’s alignment process can be performed from the printer’s menu, the printer’s software, or the printer’s maintenance tool, depending on the model and type of the printer.

The other options are not the best solutions for this problem. Reseating the new ink cartridges may not solve the shadowing issue, unless the cartridges are not properly installed or recognized by the printer. However, this is unlikely to be the case, as the printer would usually display an error message or refuse to print if the cartridges are not compatible or inserted correctly. Replacing the fuser assembly or installing the maintenance kit are more drastic and expensive measures that are usually done when the printer has more serious problems, such as paper jams, smearing, streaking, or fading. The fuser assembly is the part of the printer that heats and melts the toner onto the paper, and the maintenance kit is a set of components that need to be replaced periodically to keep the printer in good condition. These parts are not directly related to the shadowing issue, and replacing them may not fix the problem.

Fixing A Printer That Creates Shadow Images On Printouts4

The most likely reason for this issue is A. The webcam is not on a level surface.

A webcam is a device that captures and transmits video and audio signals over the internet. A webcam can be integrated or external, depending on whether it is built-in or attached to the computer. A webcam can be used for various purposes, such as videoconferencing, streaming, or recording.

An integrated webcam is a webcam that is embedded in the monitor or the bezel of the laptop. An integrated webcam usually has a fixed position and angle, and it can be adjusted by tilting or rotating the laptop screen. An integrated webcam may have advantages such as convenience, portability, and compatibility, but it may also have disadvantages such as low quality, limited features, or vulnerability to damage.

An external webcam is a webcam that is connected to the computer via a cable or a wireless connection. An external webcam usually has a clip or a stand that allows it to be placed on a level surface or attached to the monitor or the laptop. An external webcam may have advantages such as high quality, advanced features, or flexibility, but it may also have disadvantages such as inconvenience, cost, or compatibility issues.

In this scenario, an integrated webcam on a user’s laptop broke, so a technician installed a temporary, external webcam. Since the external webcam installation, other users can only see part of the user’s face during videoconferences. This could indicate that the external webcam is not properly positioned or aligned to capture the user’s full face. The most likely cause of this issue is that the webcam is not on a level surface, and it is either too high or too low, or too far or too close to the user.

To resolve this issue, the user should adjust the position and angle of the external webcam until it captures their full face clearly and accurately. The user should also check the settings and features of the external webcam, such as zoom, focus, resolution, or brightness, and modify them if necessary. The user should also test the video and audio quality of the external webcam before joining a videoconference .

The other options are not the most likely causes of this issue, because they are not related to the partial face problem. A webcam driver should be updated (option B) if the webcam is not recognized or functioning properly by the computer. A webcam driver is a software component that enables the communication and interaction between the webcam and the operating system. A webcam is plugged into the wrong USB port (option C) if the webcam does not receive enough power or bandwidth from the computer. A USB port is a physical interface that allows data and power transmission between devices. A webcam is not compatible with the OS (option D) if the webcam does not work with the operating system installed on the computer. An operating system is a software program that manages the hardware and software resources of the computer.

Optical media, such as CDs, DVDs, or Blu-ray discs, are a suitable choice for backing up a large collection of DVDs and photos in the most economical way. Optical media are inexpensive, widely available, and have a long shelf life. They can store large amounts of data, up to 50GB on a dual-layer Blu-ray disc, and can be easily labeled and organized. Optical media are also less prone to mechanical failure, data corruption, or accidental deletion than hard disk drives (HDDs) or solid state drives (SSDs).

The other options are not as economical or suitable for this purpose. A 5,400rpm HDD is a slow and noisy type of HDD that has moving parts that can wear out or break. A HDD also consumes more power and generates more heat than an SSD. A M.2 NVMe SSD is a fast and compact type of SSD that uses a PCIe interface to transfer data. However, an SSD is more expensive than an HDD or optical media, and has a limited number of write cycles before it degrades. A SAS RAID array is a complex and costly system that uses multiple HDDs or SSDs connected by a Serial Attached SCSI (SAS) interface to provide redundancy, performance, or both. A RAID array requires a RAID controller, a compatible motherboard, and a dedicated power supply.

The correct answer is C. The battery.

The battery is the component that stores and provides electrical power to the phone. The battery can degrade over time and lose its capacity to hold a full charge. This can cause the phone to stop charging at a certain percentage and run out of power faster. To resolve this issue, the battery should be replaced with a new one that is compatible with the phone model and manufacturer.

To replace the battery, the customer may need to follow different steps depending on the type of phone and battery. Some phones have removable batteries that can be easily accessed by opening the back cover of the phone and sliding out the old battery. Other phones have non-removable batteries that are sealed inside the phone and require special tools and skills to open the phone and disconnect the old battery. In this case, the customer may need to contact the phone manufacturer or a professional service center for assistance.

A patch panel is a device that connects multiple network cables in an organized and convenient way. A patch panel has a number of ports that correspond to different cables, such as Ethernet, coaxial, or fiber-optic cables. A patch panel can help simplify the wiring and management of a network, as well as provide flexibility and scalability for adding or changing network devices.

A punchdown tool is a tool that can be used to terminate network cables into a patch panel. A punchdown tool has a blade that cuts and pushes the wires into the slots or contacts of the patch panel. A punchdown tool can help create a secure and reliable connection between the network cables and the patch panel.

DNS stands for Domain Name System, which is a network service that translates hostnames to IP addresses. Hostnames are human-readable names that identify devices or services on the Internet, such as www.google.com or mail.yahoo.com. IP addresses are numerical identifiers that specify the location of devices or services on the Internet, such as 172.217.14.206 or 98.137.11.163. DNS allows users to access websites or services by using hostnames instead of IP addresses, which are easier to remember and type. DNS also allows hostnames to change their IP addresses without affecting the users, which can improve performance and security.
