Wired LAN Cables and Connectors

Wired LAN CablesLAN(s) or Local Area Networks are the small-sized sets of connections to which various users of home and office computers primarily connect. LAN networks facilitate the sharing of printers, drives and files at the same time regulating interchange to and from the internet.

Despite the fact that “Wi-Fi” connections are becoming so prevalent, the utilization of LAN cables is still applied specifically for large size networks with combined wireless and wired networks. This type of network system has a very significant part in the general operation of large networks. Thus, before you build up a large networking system, you have to know and understand how to manage a cable network well.

It is required to set up a speedy LAN network to sustain the current and future needs of your network services and applications. By tradition, UTP or Unshielded Twisted Pair structured cabling system provides fast and reliable connections using the high-speed technology – the Ethernet or Gigabit Ethernet (GE). For the potential development of your wired network, the GE for backbone LAN wiring is suggested. Using GE or even faster Ethernet together with the optical fiber backbone is mandatory in diffusing fast inter LANs.

In order to have a high performance and unfailing wire connection, a perfectly designed system for cabling is necessary. There are sets of standards and requirements in setting up a system for computer network. LAN cables commonly utilized in the network are classified into Coaxial LAN Cable, Shielded Twisted Pair (STP) and Unshielded Twisted Pair (“UTP”) Cables. On the other hand, the coaxial type is no longer employed in the current time because of the era of fast Ethernet where the UTP cables are the most in demand.

Furthermore, users of networks may be linking with one of the many classes of LAN connectors based on the type and age of device. No matter what kind of connector is being used, LAN connectors perform a similar function that is transmitting data between the connected network and computer. Sending data by means of the LAN connector, the computer can share and exchange information with the other computer units.

They can also get data on devices situated all over the world, as long it has an access to the internet. The connector uses protocol depending on the network type to which the device is linked. However, majority of the up to date connectors break up data into packets or small segments. Also, they designate an IP or Internet Protocol address matching the destination of the packet and send it out over the linked up system cable.

Regardless of the type of LAN connector, be it wired or wireless type, coaxial or Ethernet, they are the major crossing point of the internet, local network connections and computer equipment. Computers are still the main channel to access the Internet and the foremost means for operating and designing Internet services, and these connectors play an important part in the advances of computer technology.

Many users enjoy the application of LAN cables and connectors because they are the principal link between a computer device and local area networks as well as the internet. Users can exchange and share information, music, movies and files with users either on local or any connected equipment around the globe. Nonetheless, aside from the benefits and importance of LAN, using the system also involves risk. The user may produce the chances of electronic infringement; also any computer networked may encounter hacking threats from the other users.

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.

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.
