Internet Security in Your Smartphone

Smartphone and Internet SecurityIf you know the enemy face, consider that half of the battle is already won. Therefore, we suggest you get acquainted with the ten things that can interfere with comfortable walks on the Internet (including, with your smartphone).

Spyware: As the name implies, are scripts that are created specifically to spy on you. They collect information about search queries, logins, passwords, credit card data, address books, etc.

Viruses: These are script or program codes that are capable of self-replication, and unauthorized transfer from one computer to another.

Malware: This is the common name for a variety of computer programs designed specifically to harm your computer, server or network. One of the dangers of malicious programs lies in the fact that they are able to penetrate deep into the files, appearing again, even after their removal.

Trojans: Trojans enter your computer disguised as useful or important updates of the program. They are created specifically to cause damage to computers, destroying or altering information on your hard disk.

Adware: These programs are created to ensure that no consent to display advertisements on the screen of a smartphone or computer. It can be pop-up windows, automatically downloads sites, etc.

Malicious toolbars: They replicate the functionality of known panels (such as Yahoo or Google), but that analyze information stored in the memory of a computer or smartphone.

Theft browser: These scripts change the start page of the web browser without any user consent.

Cookie: This is a legitimate files that store information about your visits to Web sites and designed to make using them easier and more convenient. However, if a hacker gets access to the cookies, he learns about you very much.

Worms: This kind of virus that is able to copy the information for themselves from the PC or smart phone.

Common sense: It is the best protection against various kinds of malicious programs. Just avoid questionable sites, do not insert your flash drive in a public computer, do not open email from strangers, etc.

As for smartphones, these relatively new devices are not so heavily exposed to a virus attack. But over time, will appear more and more programs designed to steal information from your iPhone (iPhone), Android (Android) or Blackberry (Blackberry). Therefore, use your common sense and it will save you and your information. Follow above listed 10 things and their prevention method for securing your vital information.

Internet Security for Your Family

Internet Security for FamilyDoes your computer protected enough, from the unwanted and dangerous intrusions, not to mention keeping your family from stumbling across those dangerous matters on the internet?

Let’s face it, without the proper software to protect your computer, you are at risk every time you connect to the internet. There are the viruses, the Trojans and unwanted spam, not to mention the chat rooms where millions fall victim of online predators, and let’s not forget the biggest problem on the internet, pornography.

You may be saying that you have the best anti-spyware and your internet service provides parental controls. But how exactly effective are they? The truth is that 95% of internet users don’t have the adequate security to prevent attacks or control the content the computer user can access. The average computer is scanned by online intruders on average of 12 times a day.

More and more victims are realizing the importance of these safety devices. The newest trend for identity theft is to steal information and cash out, outside of the country making it impossible to trace and leaving the victims with nothing to replace the funds.

Here are some steps to take into consideration.

Evaluate- There are diagnostic tools to find and identify dangerous threats to your computer. These tools are as simple as popping into your computer and scanning your hard drive. Threats are then identified with the proper recommended course of action to take.

Eliminate- Once the threats have been identified the obvious next step is to eliminate. These security tools help scan, eliminate and block threatening spy ware, annoying ad ware and cookies, damaging worms and Trojan horses.

Protect- Set up a barrier around your computer. This will keep intruders out and create a fire wall. This is the most effective way to defend you against hackers and avoid identity theft.

Control- This final step will create a peace of mind for you, with the knowledge that you can avoid potentially dangerous web sites. You can block undesirable websites as well as avoid ones that try to download spy ware onto your computer.

Action – Find a security device that will cover these four steps and protect you from all of these hazardous things. There are even programs that will do this and automatically update every month to ensure added safety and avoid any new unknown danger.

 

The average cost for these programs, to completely cover your computer, vary from $40- $120 depending on the collection of software you use. The products that will automatically update usually run $5 – $10 a month to give you the essential idea of, get it and forget it. Too many times we forget to update our securities and fall victim of these malicious acts. Don’t wait, don’t become a victim before you take action. What is the price for your safety?

Converting Motion to Energy with Piezoelectric Technology

Piezoelectric CrystalIn 1880, Pierre and Jacques Curie discovered that certain crystals generate a charge when pressed. They deemed them piezo crystals, from the Greek for “press.” Piezoelectric crystals are transducers that turn mechanical energy into electricity. Conversely, they respond to electrical charges by expanding or contracting.

But traditional piezoelectric compounds are bulky, brittle and inefficient. They convert no more than 40 percent of mechanical energy to electricity. When subjected to an electrical field or current, they expand or contract, but only by tiny amounts.

Advanced Cerametrics piezoelectric fibers, on the other hand, are flexible. They weigh as little as two grams for a transducer that can generate 40 volts. They pick up a wider range of vibration frequencies, and generate 75 percent more power from those vibrations. And Advanced Cerametrics piezoelectric fibers outperform bulk piezos as electricity-to-motion transducers. They exert a stronger mechanical force over a larger range of motion at just 35 percent the weight. A two-gram active fiber composite strip can produce a blocking authority of 60 pounds!

Applications range

Converting motion to energyAdvanced Cerametrics manufactures is piezoelectric fibers of lead zirconate titanate, or PZT. Applications for PZT fibers fall into the two broad categories, energy harvesting or actuation. Specifically, a few opportunities stand out.

Wireless sensing

Most sensors are in environments were ambient waste mechanical energy is abundant, whether it’s inside an air duct or mounted on a motorized system. Advanced Cerametrics PZT fibers harvest that mechanical energy to recharge the batteries or power the sensors directly, without batteries.

Applications for auto-powered monitoring range from aerospace to automotive to home appliances to biomedicine.

Lighting

The higher output power of Advanced Cerametrics piezoelectric fibers opens many opportunities to power electroluminescent lighting on bridge decks, signage and buoys, among other applications.

Vibration damping

Piezoelectric Characteristics

Advanced Cerametrics PZT composites turn motion into power and power into motion. Vibration damping uses both characteristics. When vibrations generate power, built-in circuitry relays the charge to a microprocessor, which measures the magnitude of the vibration and returns an amplified signal that either stiffens or relaxes the fiber actuators. They qualify as “smart systems” for their self-adjusting nature.

In one of the best-known applications of vibration damping is by Head Sport AG of Kennelbach, Austria. Head uses Advanced Cerametrics PZT fiber composites to reduce tennis racket vibration and ski chatter.

General actuation

Advanced Cerametrics PZT fiber composites have a range of motion that opens entirely new vistas for energy-to-motion actuation. For example, piezoelectric fibers have been used to bend small aircraft wing flaps as much as 22 degrees without hydraulics.

Conventional bulk piezos move such tiny amounts that, when used as actuators, they typically require intermediating mechanisms that amplify movement. The greater range of motion of fiber piezos may allow engineers to skip these intermediating devices.

The technology is advancing fast. In our energy-hungry, battery-powered world, the19th-century piezoelectric materials have had little to contribute. But flexible piezoelectric fibers from Advanced Cerametrics offer 10 times the power output of older forms. They can be shaped in ways the user defines. They’re lighter, more sensitive and have greater actuation potential.

With these new fibers in the picture, we’re sure to see a rush of technologies that capitalize on their properties.

Internet Phone Service for Cheaper Calls Worldwide

Internet PhoneThese days we will find several Internet phone service providers across the world that provide this service at little or no cost and can help you reduce your phone bills drastically. Over the last decade, we have seen that the Internet and computer technology have changed the way people live, work and communicate. An Internet phone is one such revolution that has changed the way people talk with each other.

How does an Internet Phone work?

An Internet Phone uses Voice over Internet Protocol (VoIP), which converts the voice signal from the telephone to a digital signal. This digital signal travels over the Internet and is converted back at the other end to voice so that you can speak to anyone with a regular phone number. VoIP sends voice information in digital form in discrete packets rather than in the traditional circuit based protocols of the public switched telephone network (PSTN) and helps you use your standard Internet connection to make phone calls worldwide at a very low or no cost.

How to make a call using the Internet Phone?

To make a call using an Internet Phone, you can subscribe to an Internet Phone Service. Besides this, you need to have a good speed Internet connection in place. Some Internet Phone services allow you to use a regular telephone, as long as you connect it to an adaptor while others allow you to make calls from a computer or a special VoIP phone that doesn’t require an additional adapter.

Depending upon the service that you choose, one way to make a call is to pick up your phone and dial the number, using an adaptor that connects to your Internet connection. Another way is to use a microphone headset plugged into your computer. In this case, the number is dialed using the keyboard and is routed through the cable modem.

In fact your computer need not even be turned on in case you are making calls with a phone and adaptor or special VoIP phone. It’s just that your Internet connection needs to be active. You can even use your computer while you are talking on the phone.

Choosing an Internet Phone Service

Depending upon the Internet Phone service that you choose, you might be limited only to other subscribers to the service, or you may be able to call any phone number, anywhere in the world. The call may be made to a local number, a mobile phone, a long distance number, or an international number. You can even utilize the service for a conference call, that is, to speak with more than one person at a time.

Different Internet Phone Service providers offer various plans for making calls. Some providers offer their service for free, normally only for calls to other subscribers to the service. While others charge for a long distance call to a number outside your calling area, similar to the existing, traditional telephone service. Still some other providers permit you to call anywhere at a flat rate for a fixed number of minutes.

Before choosing an Internet Service Provider you have to carefully look at his offering and balance it with your needs.
