Technology has certainly come a long way in the past few decades. Gone are the huge contraptions that used to characterize computers. Nowadays, you can easily purchase a notebook computer that weighs in at less than 6 pounds. However, one thing hasn’t changed. Hard drives still occasionally crash and frustrated users are left trying to figure out just how to do hard drive data recovery on their own.

Hard drives aren’t perfect, although they’re amazing examples of mechanical engineering. Physical damage can easily occur since these disks are spinning at such high speeds. The smallest interference while in use can cause damage in certain areas. Various features have been put into place to reduce the likelihood of a critical hard drive failure, but these are not 100% effective. Sadly, physical damage isn’t the only reason why you may need to attempt hard drive data recovery. Many people accidentally wipe out their hard drives because they’re not sure what they’re doing.

Passing the BCMSN exam and getting one step closer to the CCNP certification means learning and noticing details that you were not presented with in your CCNA studies. (Yes, I know – you had more than enough details then, right?) One protocol you’ve got to learn more details about is VTP, which seemed simple enough in your CCNA studies! Part of learning the details is mastering the fundamentals, so in this tutorial we’ll review the basics of VTP.

In show vtp status readouts, the “VTP Operating Mode” is set to “Server” by default. The more familiar term for VTP Operating Mode is simply VTP Mode, and Server is the default. It’s through the usage of VTP modes that we can place limits on which switches can delete and create VLANs.

In Server mode, a VTP switch can be used to create, modify, and delete VLANs. This means that a VTP deployment has to have at least one switch in Server mode, or VLAN creation will not be possible. Again, this is the default setting for Cisco switches.

Switches running in Client mode cannot be used to create, modify, or delete VLANs. Clients do listen for VTP advertisements and act accordingly when VTP advertisements notify the Client of VLAN changes.

VTP Transparent mode actually means that the switch isn’t participating in the VTP domain as Servers and Clients do. (Bear with me here.) Transparent VTP switches don’t synchronize their VTP databases with other VTP speakers. They don’t even advertise their own VLAN information! Therefore, any VLANs created on a Transparent VTP switch will not be advertised to other VTP speakers in the domain, making them locally significant only. (I know you remember that phrase from your CCNA studies!)

Devices running VTP Transparent mode do have a little something to do with the other switches in the VTP domain, though. When a switch running in Transparent mode receives a VTP advertisement, that switch will forward that advertisement to other switches in that VTP domain. Read More

Spyphone is a 100% software based solution which users can download and convert any latest Nokia phone into a sophisticated spy device within a minute. Such device may have several spy features.

If you call a spy phone from a predefined number, it makes no visible or audible indication that it is in operation, and you can listen to any conversations or discussions in progress around the spy phone. Conversations within 5 to 10 metres of the spy phone are completely audible. The software can be activated or deactivated by sending a silent sms to the converted phone and works on GSM networks only.

Yet another interesting spy feature is called sms forwarding. Upon installation of the spy software on the target phone, it enables to receive duplicate copies of all incoming and outgoing text messages that will be forwarded directly to the predefined number.

The spyphone software controls the basic functions of the cell phone such as incoming call handling, backlight, log engine and installation logs. No hardware tweaking of any kind has to be made and that there are no special steps for customising the cell phone. The software is also invisible to the end user. Moreover, no parts of the software can be traced to be installed on the phone or logs of incoming calls.

Nine times out of ten you’re thinking of dunking your cellphone into the fire or mixing it in the blender because everyone else seems to be sporting a snazzy, sexy cell phone, while you are stuck with one that’s snarky, ugly, obsolete and so unhip that it’s started to look like a pig’s behind. Chances are that you are planning to call it an antique and shove it down the throat of some wacko buyer on eBay.

Let’s move on to the next step – your new cellphone. Now you need to pick up something and jazz it up so much, that you can show it off and make your buddies go green with envy. So, here are the latest ways using which, you can pimp up your cellphone:

1. Turn your cellphone into an ecosystem: In other words, convert your cellphone into an environmental-friendly product and check out the “oohs” and the “aahs” you get when you gently explain, to the opposite sex, how your cellphone actually protects the ozone layer. Don’t buy cellphones that use non-biodegradable plastics; don’t go near cellphones that coat their phones with flame retardant chemicals such as bromine-based flame retardants; conserve electricity by charging your phone as much as is required – better still, there’s a new kind of phone that’s made using bamboo and is powered by solar cells. Go for that. Our planet is getting hotter by the day; at least make your cellphone look cool!

2. Go for total convergence: First, get your cellphone hooked into a mobile radio service – there are many mobile services available and many, many more are on the way. Next, get a mobile TV service going – it’s about 10 bucks a month, but that’s nothing if you want to really pimp your buddy up. Now, get mobile VOIP (Voice over Internet Protocol) going – make calls to anyone in the world using your local connection! Bang, that’s gonna get you some cool eyeballs! Now – here’s the sucker punch – build all these features into a full screen phone! Mobile companies are coming out with full screen phones where everything is touch operated and the screen lights up when touched! Imagine a full screen phone with radio, TV and Mobile VOIP! Cool!
