Zigbee

Well you all guys have seen the movie Robot by Mr. Rajnikant , and have noticed the technology he uses in movie for the wireless data transfer i.e. zigbee ,so lets have a look What this Zigbee is?

ZigBee is a new low-power wireless communications technology for wireless networks looking for lower cost, limited functionality, reduced data size, and  protocol simplification.

Applications:

1.mobile handsets

2.local area networks

3.wide area networks

4.pc and tabs

5.high tech electronics

6.portable devices

Softwares required:

1.Bee stack

2.SMAC

Soon zigbee will replace the positions of bluetooth in your pc's and cells.

Well technology is imerging with a great upsurge and really these gadgets are the boon for us...

Which one is secure GSM or CDMA?

There is always a question in my mind whenever the thing is to choose a mobile network that wheather i take the gsm or the cdma?

But the real question is what the difference is,which one is prior??

So i just wanna enlighten some common but unnoticeable points regarding both by this article:

1.CDMA is much secured as compared to GSM as it uses code multeplexing.

2.CDMA sets uses much power than the gsm sets and this got a increase when we leave the home region,and it is due to the same code multeplexing.

3.GSm can be tapped but not the CDMA.

4.By the use of JAMMERS gsm networks can be jammed in a locality but it doesnt works on cdma.

5.CDMA is faster than GSM in data transfer,but both services are growing or we should say developing to overleap each other.

6.CDMA uses  R-UIM cards which are only compatible to their handsets while in GSM it uses SIM cards thus providing a variedness.

Well all these were just a tech difference between the two , its upon you what you choose....enjoy!!

Recognize your mail is a spam i.e. fake or not

Now a days due to the increasing passion towards the hacking and technology geeks the white hackers are in the lime light.

Spam has been a very common part now a days ,but the thing is how can we recognize that the mail we received is a fake one or not??but don wry there is an easy way in itself,just the thing is we know it:

1.For gmail users,open your inbox and then your mail you wanna check,then click on the drop down button present at reply option at top of the mail..there you will find a "show original" button click there..and then click on show header...a new window will get open and you will be able to see the original sender its i.p. and everything.

2.For yahoo users..at the end of the mail body you will see a button with name "Full Header"...just click there and you will get what you want.
