ge. The amount of charge in MOSFET transistor does not vary -- it either holds a charge 1 or it does not 0. The memory sto rage of a flash drive is created by millions of MOSFET transistors. MOSFET is an abbreviation for metal-oxide-semiconductor field -effect transistor. Threshold Voltage and Floating Gate Inside the MOSFET is what Nadre and Simon call a floating gate. Because the MOSFET's gate is an electrically isolated area an area surrounded by non-conducting insulation, the MOSFET can store an ele 3d model ctrical charge without needing to be connected to a power supply. When the floating gate is charged, the MOSFET is in an on, or 1 state. When the floating gate has no charge, the MOSFET is in an off, or 0 state. Read, Write and Erase Computers can rea PurplePixie d the memory in a USB flash drive by detecting 1 or 0. It does this by applying a threshold voltage e.g., 3V to the floating ga .
te, the threshold voltage applied to the gate will not result in a current flowing through a silicon substrate below the gate. Thi s represents 0. In short, if the computer reads a 1, the floating gate is actually is in a zero charge or 0 state. If the computer reads a 0, the floating gate is actually in a charge or 1 state.Before a computer can write information to a USB flash drive, it must first erase the flash drive's memory. This can be a bit confusing. It does this by applying an above-thresh 7 Day Diet old voltage e.g., 20V, not to the floating gate, but to the substrate of the MOSFET, which is separated from the gate by the ins ulating material. By doing this, any charge in the floating gate is pulled through the insulation into the substrate where it is PurplePixie discharged. This empties the floating gate of any charge.The computer writes information to the USB flash drive by applying an .

Sing le-band routers use the 2.4 GHz band and are limited to one wireless signal. Dual-band routers use two bands -- 2.4 and 5 GHz -- w hich means that they are broadcasting two simultaneous wireless signals, providing better performance. Speed Single-band routers u se 2.4 GHz only and are limited in speed to the Internet connection and speed of the router itself. Dual-band band routers support 3d model both 2.4 GHz and 5 GHz bands and provide faster speeds. Performance Dual-band routers have longer range and better signal strengt h, and despite their broadcasting on two different bands, there is no need to switch between bands manually, as they switch automa PurplePixie tically when needed. Single-band routers have shorter range and their signal strength is not as strong. Compatibility Single-band .
