With the uncertainty that exists in the World Wide Web at the present time, every computer must have some security device in place. Viruses and other such software can be detrimental to the life of your computer and can be contracted from virtually anywhere on the Internet. Since these elements are very difficult to immunize once they have infiltrated the surface of your hard drive, it is imperative that they be stopped before they have the chance to do so. Hence having security devices and software in place on your computer is a must, as it can easily detect threats allow you to deal with any problems that may arise with relative ease.Of particular threat to your computer is spyware. It is basically like a virus in that is spreads throughout your computer however, spyware, as its name suggests, invades the privacy of the personal computer. Thus, the purchase antispyware software is essential in securing your computer from potential threats. Some operating systems are actually equipped with a security center built-in already. This means that when you purchase the computer and operating system software you already have the services of the security center at your disposal. Such services commonly include the ability of an administrator to monitor activity throughout the system as well as potentially block hazardous material on the internet from being viewed by other users, the ability to manage automatic updates and what's more the ability to enquire about the status of antivirus software.Many of these pre-installed security mechanisms also come equipped with a firewall. A firewall is essentially a , which protects against incoming threats whether they are in the form of infections or hijackers. Without the aid of a firewall an automated hijacker could hack into your system in a matter of minutes while you are connected to the Internet, completely unaware of what is happening to your computer.
Bluetooth SecurityThese days, all communication technology faces theissue of privacy and identity theft, with Bluetoothbeing no exception. Almost everyone knows that emailservices and networks require security. What usersof Bluetooth need to realize is that Bluetooth alsorequires security measures as well.The good news for Bluetooth users is that the security scares, like most scares, are normally overdramatized and blown entirely out of proportion. Thetruth being told, these issues are easy to manage,with various measures already in place to providesecurity for Bluetooth technology.It's true that there has been some Bluetooth phonesthat have been hacked into. Most devices that arehacked into are normally those that don't have anytype of security at all.According to Bluetooth specialists, in order to hackinto a Bluetooth device, the hacker must:1. Force two paired devices to break theirconnection.2. Steal the packets that are used to resend the pin.3. Decode the pin.Of course, the hacker must also be within range ofthe device, and using very expensive developer typeequipment. Most specialists recommend that you have a longer pin, with 8 digits being recommended.Fundamentals of securityThe "pairing process" is one of the most basic levelsof security for Bluetooth devices. Pairing, istwo or more Bluetooth devices that recognize eachother by the profiles they share - in most casesthey both must enter the same pin.The core specifications for Bluetooth use an encryption algorithm, which is completely and entirelysecure. Once the devices pair with each other,they too become entirely secure.Until they have successfully paired, the Bluetoothdevices won't communicate with each other. Due tothis pairing process and the fact that it is shortrange - Bluetooth technology is considered to besecure.As the news has indicated, experienced hackers have developed ways to get around this level of basic security. There are ways to get around thisthreat, as you can install software to preventhackers from getting in.With Bluetooth becoming more and more popular, it'sreally no wonder that security is always inquestion. As Bluetooth gets bigger and better,security will always be something that no onereally takes lightly.If you've been concerned about Bluetooth securityin the past, rest assured that newer devices willoffer bigger and better security. Preventing hackers from getting in is something every owneris concerned about - and the manufacturer's arevery aware.Other wireless technology such as Garmin GPS utilizes complex wireless systems that let you know where you are, on any place in the world.
New technology is now making it possible for viewers to record and store high definition programming onto DVDs. Blu-ray Disc is one method of recording HD content onto an optical disc. A blue-laser optical disc (MPEG-2 or MPEG-4) is used. Systems that use this technology will be able to play traditional DVDs, but the goal of Blu-ray is to create an image that's as close to the HD format as possible. The name Blu-ray comes from the blue laser that decodes and copies information to each disk. Blu-ray technology may very well revolutionize the world of high definition programming. The Blu-ray disc format offers greater potential for storage, usually 25 gigabytes, which exceeds that of a standard DVD (15 gigabytes). One single-layer Blu-ray disk can hold about four hours of high definition content. A two-layer disk can contain eight hours of HD content. Four- and eight-layer disks are now in the works. These disks would have storage capabilities of 100 and 200 gigabytes. The Blu-ray recording system utilizes a shorter wavelength for recording information than traditional CDs and DVDs, and this is part of what allows it to hold more content on a single disk.Blu-ray has also influenced the computer industry, specifically in terms of data storage capability. A number of major companies have come out in support of Blu-ray, including Apple, Dell, Hitachi, Pioneer, and Sony. Hewlett Packard plans to market desktop computers and laptops that utilize Blu-ray technology. Sony has announced that it will introduce a Blu-ray component in PlayStation 3, which is expected to appear in November of this year. Microsoft has also said that it may add a Blu-ray component to its Xbox 360. Currently, Blu-ray is only available in Japan, but it will appear in the United States in May, in video games and a DVD system that recreates a high definition effect on a viewer's TV.Many movie studios have Blu-ray films planned for future release. In 2005, Sony Pictures cornered the market on the first Blu-ray feature-length movie disk, which was none other than Charlie's Angels: Full Throttle. Studios that support the technology include Walt Disney and Twentieth Century Fox.Competing with Blu-ray in the area of HD storage is HD DVD. HD DVD disks have less storage capability, but they're cheaper to produce. Other big-name companies are showing their support for this option, including Microsoft, Intel and Toshiba, as well as Universal Studios. In what may be the smartest move, some companies are backing both types of technology, ensuring that their products support both Blu-ray and HD DVD. These companies include Samsung, Paramount and Warner Brothers. Blu-ray is facing challenges from other competitors in the HD market: the Enhanced Versatile disk, the Digital Multilayer disk, and the Holographic Versatile disk are a few alternatives to Blu-ray. But at the moment, Blu-ray has a strong lead in the HD race. Check out New Technology TV for more information.
Google's PageRank (PR) system continues to ever-more dominate the internet! It seems that Google's skyrocketing influence on all-thing-internet matches the upward trajectory of its common stock shares. So, how does a website end up with a high (or, conversely, low) Page Ranking from Google. Even more importantly for high-end website owners is how to meld together all of those expensive "Flash" movies with the system Google uses to determine PR.First, though, a brief explanation of what Page Ranking by Google is all about: Google itself says that its PageRank system is at the very heart of its search prowess. It adds, "PageRank relies on the uniquely democratic nature of the web by using its vast link structure as an indicator of an individual page's value. In essence, Google interprets a link from page A to page B as a vote, by page A, for page B. But, Google looks at considerably more than the sheer volume of votes, or links a page receives; for example, it also analyzes the page that casts the vote. Votes cast by pages that are themselves 'important' weigh more heavily and help to make other pages 'important.' Using these and other factors, Google provides its views on pages' relative importance."The PR system runs from 0 through 10, with 10 being the highest possible PR achievable. Even if your website is ranked from 0-2, which is the lowest range for established sites, it may not matter because some low-ranked sites nevertheless get good search engine placement for their keywords and phrases - that is, unless, the ranking is 0 due to Google blacklisting a site for SEO blackhat spamming of one sort, or another. Otherwise, a low-ranked site owner can buckle down and work on creating links and improving site content.PR 3 can work alright in some cases but does not bode well for a site that is involved a competitive industry and work should go into improving both the SEO characteristics of the site and the breadth of its content.PR 4 is an above-average rating and indicates that there are sufficient Google "votes" for the site to make it reliable and that the site has good content. It is difficult for a new site (one that is less than 6 months old) to get a PR 4 without putting forth a lot of effort.Getting above 4 is very difficult, especially for a new site unless it is debuted with a lot of fanfare such as an IPO, or a government or educational institution's backing.Getting into PR 5 is a milestone in any website's path to profitability. While some web gurus such as Mike's Money Making Mission opine that 5 is "attainable" even poor Mike is only ranked PR 3! Additionally, a PR 5 indicates that there are many quality inbound links to the site, that it is both respectable within its industry and has very good content.PR 6's are at best reserved for mega-sites and sites with a long operating history. A PR 6 is usually major corporate, government and nonprofit web sources and is very difficult to obtain without much linking effort and broad, exhaustive content or, in the alternative, a unique system. A good example of a PR 6 is Legal Zoom which is a mega-source for low-cost legal services started by a group of lawyers and nationally advertised on TV, radio and the net.PR 7's and 8's are usually earned only by institutions of some sort or other, or, major corporations such asGeneral Motors or Delta Airlines.In the stratosphere of 9's and 10's it appears that politics can be played! For example, while Google ranks itself as a PR 10, rival Yahoo! is only given a PR of 9! This ranking brings many chuckles, as it should.With that system in mind, and the fact that both onsite optimization plus offsite quality linking go into generating a PR, how does a website built in glorious Flash get ranked? For example, a "so-call" SEO guru and expert website cries on its home page, "Don't Have A Flash Website If You Want Search Engine Results". This self-anointed expert SEO site goes on to add that "Search engines do not like flash sites." However, the site is only PR 3 despite its bravado and lack of Flash.With SEO gurus saying not to use Flash, can Flash be used anyway and still get good PR rankings? The answer is an affirmative "Yes!"A recent example is Crown SEO's all-flash website which earned a PR 4 in just 60 days after launching. How did Crown SEO do this bit of search engine optimization? First, the entire site is presented in a robust Flash movie embedded on a page that also contains detailed Meta Tags to describe exactly what the content of the movie is. The Flash includes all of the typical wiz-bang animations that Flash is so loved for plus the movie emphasizes a text-based orientation rather than uncluttered animations so common in Flash sites. But, in addition, below the Flash movie is a complete navigation bar that any search engine (including Google, obviously) can use to spider the entire site since the navbar leads to a simple text page that restates everything in the movie. Also, Crown SEO put in an extensive sitemap that links up both to the movie and to the text in a bit of search engine cross-checking, as it were. As a result, there is no search engine that could miss the sterling quality of the site's content.Thus, good content (called onsite optimization) along with good offsite efforts such as search engine registration and link building can easily result in a high PR for anyone's site who cares more about content and user satisfaction than they do about paid ads and link farms - even if they employ an all-Flash site.
I think we've reached a consensus that there's a conspiracy afloat. You go to your local office supply store or membership warehouse, and find the deal of the century on a laser printer, photo printer, or inkjet printer. You take it home and are delighted by the quality of the prints, the speed of the printer, and most of all, that your new printer was incredibly inexpensive. The next thing you know, though, the starter toner cartridge that came with your new printer runs out, and you discover that the replacement cartridge costs about half of what you paid for the printer.Yes, printer manufacturers are able to offer such low prices on printers because they make so much profit on toner cartridges. At least that's the case when you buy an Original Equipment Manufacturer, or OEM, inkjet printer cartridge or LaserJet toner cartridge. You are probably aware that there are other types of ink cartridges and laser toner cartridges available, but perhaps you've been wary of them. After all, printer manufacturers warn of dire consequences like equipment ruination unless you buy brand name (or Original Equipment Manufacturer) toner. The truth is, there are compatible inkjet printer cartridges and LaserJet toner cartridges that not only meet, but that actually exceed the specifications of the equipment manufacturers. These cartridges are brand new and provide you with toner or ink that will produce the high-quality prints you've come to expect - without compromising the parts or lessening the lifespan of your printer.In addition to Original Equipment Manufacturer and compatible "ink cartridges" and toner cartridges, you can also find what are called re-manufactured cartridges. These are different from compatible cartridges in that they are OEM cartridges that have been used and refilled. Good re-manufactured cartridges consist of more than simply filling a used cartridge with ink or toner, though. For example, an inkjet printer cartridge and the print head nozzles will be cleaned. Then, once the inkwells have been filled with ink that matches the ink found in Original Equipment Manufacturer cartridges, the cartridge is extensively tested to ensure that it will do the job. It will, for example, go through tests to ensure it doesn't leak, its circuitry is functional, and the pressure inside the cartridge is exact. The key to finding the right kind of "laser toner" or inkjet ink at the right price is understanding the difference between Original Equipment Manufacturer products, compatible products, and re-manufactured products. Next, you have to find a reputable supplier of compatible toner cartridges and inkjet printer cartridges. The Internet is the best place to start. When you do, you'll feel more comfortable with taking the plunge and buying something other than the pricey cartridges available at your local office supply store. You'll be surprised that you can save a ton of money - as much as 85 percent! When you do, that low price you paid for your laser printer, photo printer, or inkjet printer will, indeed, be a bargain.
