How do 3D printers work? What sort of applications do these printers have?
Initially, a 3D model is created on a computer using special software. When it is transferred to the printer, a nozzle will heat special plastic material until it melts. This nozzle will expel the liquid in a series of layers, which quickly hardens into solid form. There are countless applications for 3D printing that range from the creation of plastic toys at home to producing equipment and parts for astronauts that are stationed on another planet.
List three common uses for computer microphones.
Internet voice calling, capturing the audio portion of a video recording or conversation, and speech recognition for commands and dictation.
List four common uses for digital video cameras.
Online conversations, security and surveillance, recording video, and capturing body movements and facial expressions.
T/F A computer's sound card is a circuit board that converts sound from analog to digital form, and vice versa, for recording or playback.
T
T/F Add-on circuit boards that can improve the performance of a computer's video or sound are known as expansion cards.
T
T/F Apple's Siri and Google's Search app both employ speech recognition, allowing users to issue voice commands on their mobile devices.
T
T/F Because solid state storage does not use moving parts, this technology can perform read, write, and erase operations at much quicker speeds.
T
T/F Having a higher quantity of RAM will allow you to have more open programs and quickly switch between them.
T
T/F Many computers do not need a video card because the video-processing circuitry is built directly into the motherboard.
T
T/F Many modern game controllers include internal sensors that can detect subtle movements of the device.
T
T/F Many of the components inside a computer generate a great deal of heat. Without proper cooling, a computer could overheat and malfunction.
T
T/F Tape drives, which use magnetic tape to store data, are popular for organizations that have large quantities of information to backup or archive.
T
T/F The CTRL, ALT, FN, and WINDOWS keys are commonly used for keyboard shortcuts, which are keystrokes that can quickly perform an operation within software.
T
T/F The motherboard is the largest circuit board in a personal computer.
T
T/F When you plug a power cable into the back of your tower-based computer system, you are essentially connecting it to the power supply.
