Say Goodbye to Traditional Telephone Lines

Written by Michelle Lehoux

Like old, dusty books onrepparttar shelves of public libraries, regular home telephone lines have been plummeting in popularity. Some experts even foresee that traditional LAN telephone lines will eventually reach extinction- but before you start to chuckle at this forecast, it may be less farfetched than you actually think.

“Many people don’t leave home without their cell phones nowadays,” says Larry Lehoux,repparttar 140869 CEO ofrepparttar 140870 Data Corp., a world leader inrepparttar 140871 development of digital communications software. “Cell phones have really revolutionizedrepparttar 140872 way we live; people no longer need to sit and wait around for important phone calls. Cell phones have given us freedom.”

It’s true. Most of us carry our cell phones around everywhere;repparttar 140873 grocery store,repparttar 140874 mall, in our cars and even atrepparttar 140875 gym. Cell phone use has been steadily increasing aroundrepparttar 140876 world and people are not just using their cell phones to talk, there are now a variety of other activities that are keeping their interest.

“Mobile phone technology is becoming so sophisticated that people use their handsets for tasks other than just talking. These new activities include text messaging, download ringtones and wallpaper, playing games and even surfingrepparttar 140877 Internet” says expert Lehoux.

How to read Zener Diode Code

Written by Jestine Yong

Many technicians are confused on how to really read a zener diode code. There are many types of code number indicated on it's body. The look and shape of a zener diode sometimes can be mistaken to be a normal signal diode. To differentiate it, is by looking atrepparttar code number on it's body- whether it is a normal diode or zener diode. Thanks torepparttar 140730 manufacturers where their main boards are printed withrepparttar 140731 word 'ZD' which referred to zener diode and 'D' means a diode. However, from my experienced some printed circuit boardrepparttar 140732 marking of 'D' also can represent zener diode. This will misled a technician into believing a zener diode is actually a diode. We as a technician or engineer must know or be sensitive aboutrepparttar 140733 marking. The only way to find out is by referringrepparttar 140734 code number printed onrepparttar 140735 component's body from a semiconductor data book. Without data book it is quite difficult to knowrepparttar 140736 actual zener diode voltage. If you do not haverepparttar 140737 data book you may go to google search engine and typerepparttar 140738 following code and hope you can findrepparttar 140739 answer there! A wrong substitution of zener diode may caused your equipment to malfunction and sometimes will even blow your equipment. Time and money are loss due to that we lack of knowledge of identifyrepparttar 140740 right zener diode voltage. If you are unable to identifyrepparttar 140741 code, do not worry as this newsletter are here to guide you to successfully on how to readrepparttar 140742 zener diode code.
