Hai Friend,
There is a easy way to remember the color coding of resistors which i have been told in my college:
BB ROY Great Britain Very Good Wife.
The capital letters indicate the colors with a value from 0 to 9. Black(0), Brown(1), red(2), Orange(3),yellow(4), Green(5), Blue(6), Voilet(7), Grey(8) and White(9).
The first two colours represent the direct numbers and third digit indicate the value to which this number has to be raised to the 10th power.The last color indicate the accuracy of the resistance.
Probably I'm dating myself, but I learned it in the "Bad Boys...." version.
Here's one for the seven-layer OSI model:
Please (Physical)
Do (Data Link)
Not (Network)
Take (Transport)
Sales (Session)
People's (Presentation)
Advice (Application)
No offense intended for, nor directed toward, the vendor/service provider community, from whose professionalism, expert judgement, and hard work I have benefited greatly throughout my career.
