Why use anti-static protection?
Working on computer hardware can be a tricky thing. A small mistake could mean the difference between a great computer system and a completely dead piece of hardware. The easiest, least noticeable incident that could happen is electro-static discharge (ESD). ESD is able to happen so easily that most of the time we're unaware of it. It only takes 30 volts or less to destroy most computer components, and a noticeable discharge takes a few thousand volts, so we highly recommend using anti-static accessories when building your system.
How do I use anti-static protection?
Anti-static wrist straps connect are connected to a cable with a metal alligator cli on the end. Clip the cable onto your computer case or other grounded surface and touch that surface right before you handle your computer hardware. Using anti-static mats (which work similary to the wristbands) and gloves are also good options when working with computers and digital hardware.
What are anti-static bags used for?
You can pretty much use an anti-static bag for the safe storage and transport of any electronic device. The reason for doing so is to prevent static build-up or shock to the device (which in a lot of cases can damage or ruin the device, the storage, etc.) Most commonly you'll see anti static bags used with motherboards, hard drives, and RAM / memory as those are some of the most sensitive components on a PC.
