Procedures to protect equipment and data

Procedures to protect equipment and data

1. ESD

   • atleast 3000 volts must build up before a person is able to fell electrostatic discharge
     • to prevent against this use antistatic mat and antistatic wristband
   • climate and poor quality source of electricity can cause damange to computer

2. climate

   • if the temperature is too high equipment can overheat
     • can not change the weather but can try to control the tempertaure in the room you are in for example have air conditioning
   • if the humidity is too low ESD increases
   • if humidity is too high equipment can be daqmaged by moisture

3. EMI

   • is the intrusion of outside electromagnetic signal in a transmission media

4. Blackout

   • the loss of Ac power for example when a fuse blows this can cause a blackout

5. Brownout

   • reduced voltage level this happenes when the power line voltage drops below 80% and it also can happen if electrical circuits are overloaded

6. Noise

   • interference from generators and lightning
   • noise results in poor quality power this can cause errors in computer system

7. spike

   • Sudden increase in voltage that doesn't last for a long time
   • they can be caused by lightning or can also happen after a blackout

8. Power surge

   • Dramatic increase in voltage higher than normal flow of electric
   • it will last a couple of nano seconds or one billionth of a second
