I need help on my technology homework?

Question

I need help my college professor went over things with the ESD strap and I didn't catch all of his lecture so I missed some of the things he talked about now I am at a loss with this question can anyone help me? Here it is ......


Discuss why it is important to wear an ESD wrist strap while working on most computer components. Use three examples of repairs where the ESD strap should be worn? Be specific with your details.

Can anyone please help my professor will not help me with this!!!!!!!!!

Thanks for the answer just one more.

List 2 situations where an ESD strap should be worn

Answer 1

ESD is electrostatic discharge. Use it when removing expansion boards, touching the motherboard, or removing drives. Any static you carry in your body will be discharged onto the components, causing damage. You don't have to feel the shock to damage something.

Your body is a big electric battery. Any amount of friction causes electricity to be stored. Touch something metal and it discharges. The ESD is like a lightening rod directing your electricity to the grounded computer case.

Answer 2

ESD, or ElectroStatic Discharge, is one of the few things an individual can do to damage or destroy his or her computer or hardware components. Much like the shock you receive when rubbing your feet on the carpet and touching something metal, ESD can occur when working in your computer and will cause components you touch to no longer work properly. ESD can occur without the user feeling a shock and will only occur while working on the inside of the computer or handling an expansion card.

HOW TO HELP PREVENT ESD

The best method of preventing ESD is to use an ESD wrist strap and/or use a grounding mat or table. However, because most users do not have access to such items, we have included the below steps to help reduce the chances of ESD as much as possible.

Zero Potential - Most importantly, make sure you and the computer are at Zero Potential by continuously touching an un-painted metal surface of the chassis or the computer power supply case.
Standing - It is also very important that you are standing at all times when working on the computer.
Cords - Make sure everything is removed from the back of the computer (power cord, mouse, keyboard, etc).
Clothes - Make sure not to wear any clothing that conducts a lot of Electrical Charge, such as a wool sweater.
Weather - Electrical storms can increase the ESD risk; unless absolutely necessary, try not to work on a computer during an electrical storm.
Accessories - To help reduce ESD and help prevent other problem, it is also a good idea to remove all jewelry.

DAMAGED HARDWARE

If after working inside your computer and/or adding additional hardware your computer no longer boots properly, please try the below recommendations.

If you have added a new component, remove it and try booting the computer. If the computer boots, it is likely an incompatibility between the computer and that hardware device. Try it again just to make sure.

If the computer still does not boot properly after removing the new hardware or you did not add any new hardware, make sure that all the cables are firmly connected to their devices. It is possible that a cable may have become loose. This also includes the cables going to the back of your computer; make sure your power, monitor, mouse, keyboard are connected.

Make sure each of the expansion cards in your computer are firmly seated into the slots and not partially seated.

Unfortunately, if your computer still does not properly boot, it is very possible that you may have mistakenly damaged your computer or a component within the computer causing it not to work. If the computer is beeping abnormally, refer to our beep code page for recommendations and beep code listings.

Answer 3

An Anti-static wrist strap or ESD wrist strap is a device used to prevent electrostatic discharge (ESD) by safely grounding a person working on electronic equipment.

Basically the strap is to prevent static electricity in the body from damaging electronic equipment. A technician would want to wear one when removing or installing RAM, a CPU, or any other sensative component.

Answer 4

ESD is electro-static discharge. Basically what happens when, for example, you scuffle your feet over the carpet and touch someone and it shocks them. It is the transmission of a very minor amount of electricity, but even this minor amount is sufficient to screw up the sensitive innards of computers.

The ESD strap effectively grounds you and prevents the transmission of the current from your body to the PC.

Times you should wear it when doing repairs? Well, honestly you can't go wrong if you always do, but for the sensitive areas you want to be 100% sure you are grounded (though there are other methods of doing so). If you are replacing a CPU, adding ram, replacing a motherboard, heck even upgrading your video card, you just Dont want to be transmitting any static through your body. These pulses of electricity are minor and harmlesss to us as humans, but to the sensitive, tiny (think etched layers of circuits in the mobo - so so so small but so critical) parts in your pc, even a minor pulse of static can cause damage from minor to major levels.

good luck.

Answer 5

Esd stands for electro static discharge. It is a good Idea to use one if you are touching anything inside of the case. The static spark that you sometimes get in the wintertime when you walk accross a carpet and touch a metal object or another person can run somewhere in the 30 volt range which is more that most internal pc components can bear. If you are changing any of the cards,memory,modems etc. you should use one.

Answer 6

ESD= Electric Static Discharge

The strap or pad is used when repairing a pc, it is vitally important to use this strap or mat when working on the motherboard, any electrical parts of the pc or when servicing the pc... This wrist strap or floor mat will prevent you from shorting out the vital electrical parts of a computer when installing, upgrading or basic servicing..

Answer 7

I work on computers, I don't wear one, I have never fried a single component. I'd tell this professor he was outdated. Modern electronics are far more resistant to electrostatic shock than they were say back in the 90s. Just make sure you discharge yourself BEFORE you start working on a computer, don't work on carpet and you won't need to wear one of those bands, because honestly, if anyone is looking, I feel like a geek if I wear one of those things. There are arguments for both. I would only wear one if I was working directly with the components while standing on a carpet which has happened all of never.

So, it's not really useful to wear one if:

You have already been grounded and discharged yourself
You ARE NOT working on any type of carpet

Wear one if:
You are working on carpet or in a very dry environment (I'm talking Mojave dry).

I've never found it useful to wear one, I've never fried a component and if your professor has a problem with that, you tell him to contact me. He either sounds like a dinosaur or sounds like someone who doesn't know what he is talking about or just sounds like he wants to play it safe all the time, none are personalities I tolerate very well.

Answer 8

Well a ESD strap is used to deflect static discharges. Your examples would all be situations where you would be handling components that could be damaged by the discharge.

Answer 9

yOU NEED THAT STRAP to ground yourself to Earth because you could cause an electrical(static electricity) discharge to the electronic components . CMOS (C omplementry M etall O xide S emiconductor) chips especially and damage them.
Because when your body is charge staticly it discarges to ground wherever it finds a way (just like LIGHtening) so if you weare the band and ground it to the Computer chassis (or whatever electronic component) best is a Desktop or the chassis, your Body static goes via the grounded cable straight to earth.
Take care!.

Answer 10

It grounds static electricity that could fry a component.

Three examples are replacing a CCD chip in a camera, replacing memory in a laptop, and replacing a CMOS processor in a handheld computer.
