Reconnect Internet Technology Tips

It’s probably not something many people are interested in unless they’re some kind of an electrical engineer or just bored, but understanding how an antenna works can be useful when the one on your TV or radio goes south on you and the reason is beyond your comprehension.

Trying to explain how an antenna works in simple English is not an easy task as there are a lot of technical specifications that need to be explained. But a general understanding is possible without getting into tech speak that would make Einstein cringe.

In order for an antenna to work it has to radiate. Your antenna, whether TV or radio has what is called free electrons running through it. It is these free electrons that vibrate. The question becomes, how do these free electrons vibrate and what causes them to vibrate?

Well, in real life it takes an electric field to move an electron. If you take an isolated straight dipole, the power comes from the combined fields of all the charged particles, both positive and negative, in the antenna. We’ll call this field the antenna’s coulomb field.

In addition to this field, the antenna exhibits a magnetic field that is the sum of the magnetic fields of all the free moving electrons. The antenna also has a dynamic electric field that is the vector sum of the dynamic electric fields of all the free electrons. What we can do is separate the electric field of the antenna at any point in space into two components. One of the components will be in phase with the total magnetic field and the other will be 90 degrees out of phase. The in-phase component is the radiation field of the antenna and the out of phase component is the induction field. At the antenna, both fields are parallel to the metal surface.

What happens is that the coulomb field and the induction field fall off much more quickly than the radiation field as the distance increases from the antenna. When you reach distances greater than a few wavelengths from the antenna, you have what is called the antenna’s far field. This field is pure radiation. As you get closer to the antenna you have what is called the antenna’s near field. This field is a mixture of radiation, coulomb, and induction fields. Still with us? Great, we’re getting to the good part.

A new unique MultiCore AntiVirus & AntiSpyware product reliably defends PC against computer malware and on-line threats at unsurpassed, highest security levels.

A MultiCore AntiVirus & AntiSpyware product ( http://www.nuwavesoft.com ) effectively prevents, stops, and eliminates computer viruses and spyware. The revolutionary underlying software technology enables multiple antivirus and antispyware scan-engines running on the same PC. A MultiCore AntiVirus & AntiSpyware product is truly unique, because it offers unprecedented security benefits of running multiple antivirus and spyware scan-engines simultaneously, in parallel, and without performance degradation! No other computer security product for PC in the world is capable of or offering that to date.

What multi-core antivirus and antispyware solution means? Comparatively speaking, you can imagine all the benefits of having computer processor with more than one CPU core. The modern multi-core computer processors allow smoother performance and much increased speed of computer applications, which translates into better overall experience delivered to the end-users.

Conceptually similar, a multi-core antivirus and antispyware solution runs multiple antivirus and spyware scan-engines simultaneously and in parallel. As result, it delivers exceptional performance while providing the strongest protection against malware and on-line threats. With total four anti-malware scan-engines employed, MultiCore AntiVirus & AntiSpyware product continuously scans PC at the same speed as traditional single-core solutions from competitors, while delivering unprecedented four times the protection! Currently, MultiCore AntiVirus & AntiSpyware product utilizes world’s leading two antivirus and two antispyware scan-engines: Frisk ( http://www.f-prot.com ), Norman ( http://www.norman.com ), Lavasoft (http://www.lavasoft.com ), and Sunbelt (http://www.sunbelt-software.com ).

Why end-users need a multi-core anti-malware solution? Are traditional single-core computer security products not enough? Well, the truth of the matter is that none of the traditional single-core computer security products can provide 100% protection alone. There are at least seven major computer security vendors in the world who claim that precisely their brand is the world’ leading solution. And yet multiple tests performed by credible and independent computer security certification institutions ( such as http://www.virusbtn.com , http://www.westcoastlabs.org , and so forth) do demonstrate year after year that even the very best individual single-core computer security product can only deal with approximately 98% of the existing computer viruses and spyware. Of course, there is no conscious end-user who wants to be unprotected and to face remaining 2% computer viruses and spyware and yet they all do, unfortunately. A MultiCore AntiVirus & AntiSpyware product eliminates this problem! Each and every individual scan-engine differs from the other. And all scan-engines have their own specific pros and cons in certain areas, such as heuristics, scanning speed, dealing with unknown malware, and so forth. So, all end-users inherently tied up with those pros and cons of the underlying single-core scan-engines. A MultiCore AntiVirus & AntiSpyware product eliminates this problem too! Also, concerned computer users sometimes install more than one computer security solution their PCs. Little do they know that the different security products do not live well with each other on one PC – they constantly conflicting and causing instabilities and a sizeable performance hits too. It is not uncommon for end-users to have PC crashes when the two or more antivirus or other security products start fighting for control over PC. By engineering the four security cores together, MultiCore AntiVirus & AntiSpyware product eliminates these problems completely! Read More

IT network managers have to fight the “if it ain’t broke don’t fix it” mindset to win resources. With computer networks, that mindset is dangerously complacent. IT networks will keep pumping data until they die or let in hackers. Here are some winning arguments against “if it ain’t broke…”

IT Network Maintenance: Better Analogies

Don’t let your IT network’s budget get lumped with IT in general–or worse, operations in general. “If it ain’t broke, don’t fix it” sometimes makes sense in IT or operations. Upgrading workstations or desks can cost productivity, making it self-defeating.

You have to stress that IT networks are different from workstations or desks.

• IT networks are harder to repair.
• IT networks cannot be done without until fixed. You depend on them for email, web, file transfers, and in some organizations, printing, fax and telephone. If your network breaks you may be forced to rely on hand-written letters.
• IT network improvements rarely lower productivity on the front line. Instead, a faster, more reliable network can improve front-line productivity.

Here are the analogies you should stress to counter “if it ain’t broke”:

• Plumbing: IT networks will appear to function until they burst. The damage will be more expensive than maintenance ever could have been. In the meantime, you are losing productivity to all the little “leaks.”
• Dams: If a poorly maintained IT network bursts, the eventual flood will harm overall productivity.
• War: There is no such thing as “good enough” when you are in competition. With an IT network, you’re in a quiet arms race with hackers. You are also competing with your business competitors in terms of productivity.
• Health: Your IT network has to be in top physical condition. You can’t make up for bad habits with a week or two of “rejuvenation.” Meanwhile, your day-to-day performance will suffer.
• Cars: Don’t wait for your IT network to conk out. Get a regular tune-up of up-to-date equipment.
