How does a wireless network work?
Wireless networks work similar to how cordless phones work, through radio signals to transmit data from one point A to point B. The sender of the radio signal mixes data into the radio signal in a process called modulation. The receiver can obtain this data by demodulating the received signal.
Wireless technology has restrictions as to how you can access the network. You must be within the wireless network range area to be able to connect your computer. Besides that, a wireless network may be protected by a password.
There are two different types of wireless networks Wireless Local Area Network (WLAN), and Wireless Personal Area Network (WPAN).
Wireless Local Area Network (WLAN)
In a wireless local area network, a device called an Access Point (AP) connects computers to the network. The access point has a small antenna attached to it, which allows it to transmit data back and forth over radio signals. With an indoor access point as seen in the picture, the signal can travel up to 300 feet. With an outdoor access point the signal can reach out up to 30 miles to serve places like manufacturing plants, industrial locations, college and high school campuses, airports, golf courses, and many other outdoor venues.
Wireless Personal Area Network (WPAN)
A WPAN network is a wireless network on a smaller scale than a WLAN network. It also uses radio as a carrier signal, but with a different frequency and wavelength. Bluetooth is the industry standard wireless technology used for WPAN. Bluetooth devices in WPAN operate in a range up to 30 feet away.
Compared to WLAN the speed and wireless operation range are both less than WLAN, but in return it doesn't use nearly as much power which makes it ideal for personal devices, such as mobile phones, PDAs, headphones, laptops, speakers, and other devices that operate on batteries.

The heating element of an electric heater is a "resistor", the cord which conducts the electricity is not.
The resistance of the element of an electric heater is very high. As current flows through the heating element, it becomes red hot and glows. On the other hand, the resistance of the cord is low. It does not become red hot when current flows through it.

Electric Bass = More freedom for guitar to do whatever.
Electric Piano/Synthesizer = More sounds
Multi-track recording = One person able to record a song themselves
High Quality Microphone = much more response on all frequencies with ability to rid of buzzing/hissing
Internet = allowing for people to share their music to everyone possible
Subwoofers = allowing people to feel the music as if they were present

Is CPU retain the information when power to the computer system is turned off?
No. The microprocessor is simply a bunch of tiny switches that when switched a certain way process data according to a program. When you turn the power off all the switches are reset. To get the microprocessor to set the switches again it needs to get instructions from somewhere else, usually the BIOS, this is what it is doing when it boots. Only the BIOS and the hard drive retain data when there is no power.
How do you make your desktop disappear?
1) Right-click the icon you want to make invisible and in the menu that appears choose Properties.
2) Press the Change Icon button.

6) In some versions of Windows you may have a small arrow remaining on the desktop at this point. To hide it, go to the Start menu, click Run and enter regedit.exe. Locate the 'HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Inkfile' registry key, delete the IsShortcut parameter and restart the computer.
Can a 100 mA adapter be substituted with a 200 mA adapter?
A 9V 1A adapter will supply up to 9 Watts of power and a 9V 200mA adapter delivers up to 1.8W of power. The 200mA adaptor may not be able to supply enough power to a device that has been supplied with a 1A adapter. The 1A adaptor should operate equipment that originally used a 200mA adapter.
Before using a different power supply, check that the outputs are both DC or both AC. If they are both DC, it is important to check that the polarity at the connector is the same for both. If AC and DC supplies are swapped or the polarity is swapped there is a risk that the equipment will be damaged.
