Then you can implement the fix as needed.
Which is a common factor that might cause a CPU to fail prematurely?
ESD (electrostatic discharge)
Fused deposition modeling (FDM) is a 3D printing method that is often used in entry-level desktop 3D printing. Which of the following components does the FDM method use to create a three-dimensional object? (Select two.) Vat with moveable platform Filament thread Extruder assembly Ultraviolet light Liquid resin
Fused deposition modeling (FDM) is a 3D printing method that uses an extruder assembly and filament that is threaded into a moveable printhead. The 3D printing method that is called stereolithography (SLA) uses a laser beam of ultraviolet light to build a 3D object on a moveable build platform that is submerged in a vat of liquid resin.
ou are building an HTPC (home theater PC) that will be connected to an HDTV. You want to be able to play Blu-ray movies on the HTPC. Which of the following features should your video card and HDTV MOST likely support? HDTV HDCP OpenGL DirectX
HDCP High-bandwidth digital content protection (HDCP) is a method for protecting digital media, such as Blu-ray movies, from being intercepted and copied. When playing protected content from a PC, the optical device, video card, and external display must all support HDCP. Both DirectX and OpenGL are API collections that are used to improve graphic, animation, and multimedia creations. HDTV is a high-definition signal used to broadcast digital TV signals.
Which of the following protocols is often combined with TCP to send data across the internet? answer FTP ICMP UDP IP
IP - TCP is most often combined with Internet Protocol (IP) to send data across the internet. IP is responsible for determining how to deliver the data between two hosts, and TCP is responsible for the segmenting and sequencing of the data packets. - User Datagram Protocol (UDP) is also used alongside Internet Protocol as an alternative to TCP to send data across a network. UDP is a connectionless protocol.
You are putting together a gaming system and need to make sure that you find a display that meets your needs. The display needs to have a very good response time, and you would prefer that it be affordable and power-efficient. Which of the following display types will MOST likely meet these needs?
LCD TN - LCD displays with TN panels are the most common technology used by LCDs. TN panels have very good response times (1 to 5 ms) and refresh rates (60 to 144 Hz), so they are great for PC gaming. They are more affordable and have faster response times than LCDs with IPS panels, use far less power than a plasma display, and are far more affordable than OLED displays.
For several years, your laptop's monitor has worked perfectly. However, shortly after turning on your laptop today, you notice that the dimness has increased on the screen. Which of the following is the MOST likely cause? (Select two.) The power adapter was accidently unplugged The brightness level was automatically reset to the default settings. The monitor's resolution was automatically reset to the default settings. The monitor's inverter has gone bad. The monitor's hertz rate is set too high.
The monitor's inverter has gone bad. The power adapter was accidently unplugged - Since you know that you haven't changed the brightness settings, it is very unlikely that these settings would be changed automatically.
Your Windows 11 system powers on, but there is no image on your display. You have already checked to make sure that the monitor is connected properly to the computer, is plugged in, and is turned on. Which of the following is the BEST next step you should take to try to resolve the issue?
Verify that the BIOS/UEFI is configured to use the correct video adapter.
Which of the following is another name for the paging file?
