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

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
