Hint

When a mobile device cannot connect to a Bluetooth device, a user should check to verify that Bluetooth is turned on, that the Bluetooth device is paired with the mobile device, and that the mobile device is within range.

Hint

A swollen smartphone battery could have several causes, including being overcharged, being charged with an incompatible charger, or the battery itself could be defective.

Hint

The computer sharing the printer uses its own resources to manage the print jobs coming to the printer. If the computer user on the desktop is working at the same time as a user on the network is printing, the desktop computer user might notice a performance slowdown. In addition, the printer is not available to others if the user reboots or powers off the computer connected to the shared printer.

Hint

A hardware print server allows many users to print to the same printer without using the resources of any computer. A computer-shared printer uses a computer to manage all of the print jobs. There is no software print server. Installing a second printer would reduce the print jobs on any one computer, but would still use computer resources.

Hint

A digitizer is a special glass piece attached to the front of the screen on a laptop. The digitizer converts the touch actions (press, swipe, etc.) into a digital signal that is processed by the laptop so that the displayed content will change accordingly.

Hint

Near Field Communication (NFC) enables mobile devices to establish radio communications with other devices by placing the devices close together or by touching them together.

Hint

The print spooler error message indicates that the printer service has stopped or is not working properly. The user can either try to start the print spooler or reboot the computer, which will restart the printer service.

Hint

The problem is caused by a wrong or outdated print driver installed in the computer. A print driver is a piece of software on a computer that converts the data to be printed to a format that a printer can understand.

Hint

The problem is that the user account does not have administrative privileges on the computer.

Hint

A dot matrix printer is a type of impact printer. Impact printers have print heads that strike an inked ribbon, causing characters to be imprinted on the paper. The striking force will make characters imprint on multiple sheets of paper.

Hint

When several apps will not open, the apps might have been moved between storage options or installed to a flash memory card that has been removed. Reinstall the apps or reinsert the memory card.
