  Explanation

  An impact printer is a type of printer that uses a ribbon to produce text and images on paper. If an impact printer is producing faded text and images when printing, it could be due to a worn-out ribbon that needs to be replaced. The technician would need to replace the ribbon on the impact printer to resolve the issue. A ribbon is a consumable component used in impact printers that uses a cloth or plastic strip coated with ink to produce text and images on paper. Examples of impact printers include dot matrix printers and line printers.

• Question 1026:

  A user, who is attempting to give a presentation via a projector in a conference room, reports the projector has video but no audio. Which of the following will MOST likely resolve the issue?

  A. Changing the input on the projector to VGA

  The issue of video but no audio on a projector in a conference room can be resolved by utilizing an HDMI connection between the PC and the projector. HDMI supports both video and audio signals and is commonly used to connect a PC to a projector for presentations. Changing the input on the projector to VGA, changing the output on the PC to DVI, or modifying the projector's refresh rate will not resolve the issue.

A high-end graphics card can draw up to 300 watts of power or more when running games or other graphics-intensive applications24. https://www.buildcomputers.net/power-consumption-of-pc-components.html

• Question 1030:

  A user is reporting that a computer has been very slow in recent days. The technician looks into the problem and finds pop-ups are randomly appearing on the screen. Which of the following is the next step the technician must take?

  A. Establish a knowledge base.

The sudden appearance of pop-ups and the computer's slow performance could be indicative of malware or potentially unwanted programs (PUPs) running in the background. By identifying this as a possible cause, the technician can then proceed with a plan of action to diagnose and address the issue, which may involve running antivirus or antimalware scans, removing suspicious software, or performing other remediation steps as necessary.
