$12.99. 1  Pros Easy-to-use software. 2  Cons Expensive. 3  Bottom Line AnchorFree Hotspot Shield Elite is a fast and capable VPN that throws in antivirus protection along with other extras. But it's still expensive for what you get.
Common electrostatic-sensitive devices include: 1  MOSFET transistors, used to make integrated circuits (ICs). 2  CMOS ICs (chips), integrated circuits built with MOSFETs. 3  Examples are computer CPUs, graphics ICs. 4  Computer cards.
Many of these electronic systems are controlled in some way by semiconductors. Semiconductor devices fail when they encounter an EMP because of the local heating that occurs. Failure of semi-conductive chips could destroy industrial processes, railway networks, power and phone systems, and access to water supplies. Commercial computer equipment is particularly vulnerable to EMP effects.
