Study Notes
Wireless Networking Technologies
- Bluetooth devices communicate using a personal area network (PAN), similar to an ad hoc wireless network.
- Bluetooth uses 2.4 GHz radio waves, which can go through walls, unlike infrared that requires line-of-sight transmission.
- Infrared uses red spectrum light waves and is limited to line-of-sight transmissions.
Laser Printers
- The primary corona prepares the photosensitive drum for writing by causing the drum to receive a negative electrostatic charge.
- The transfer roller charges the paper to attract the toner.
- The toner sticks to the charged areas on the drum.
- Fusing rollers attach the toner to the paper by pressing and melting the paper.
Network Troubleshooting
- If the network card stops working, you can use an ExpressCard wireless network card, a wireless USB network card, or other alternatives to connect to the wireless network.
- To troubleshoot weak wireless connections, you can try moving the wireless access point, adding a network extender, or moving your workstation closer to the wireless access point.
PC Cards and Devices
- Hot swappable refers to inserting and removing PC cards without rebooting the computer, also known as dynamic reconfiguration.
- Plug-and-play devices are automatically detected by the system, and the driver is automatically loaded.
- AT attachment (ATA) is the standard interface for transferring data from storage devices such as hard disk drives and optical drives.
Printer Troubleshooting
- The most likely cause of print problems, such as printing random characters, is the wrong printer driver being selected.
