Data encryption was first used by the government, mainly to guard military secrets. In today’s world of Internet businesses, this method of protecting your computer data is being used more and more by financial institutions and other businesses as a means to prevent anyone from gaining unauthorized access to money transfers and other financial matters.

There are several different types of encryption methods that are available. Hardware based encryption is considered to be the best by many computer experts. This type of encryption is placed directly on your computers hardware, which allows you to protect your data even if your operating system is not active.

One of the major advantages that a hardware based encryption system has over the other types is the fact that it can be made virtually transparent to software. This factor simply means that this encryption is transparent to the operating system, allowing it to be used with any system that you may have.

Due to this transparency, hardware based encryption may also enhance your operating system’s performance. When integrated with the media itself, this hardware may lead to the media being designed for better integration with other operating systems.

Critics of the hardware based encryption point out that due to its size of its keys (some being as small as 40 bits), this encryption can easily be subjected to brute force attack. This attack is the way that outside sources can systematically try all the possibilities and combinations of the keys to decrypt all of your data. By only implementing 40 bits, the number of possibilities is at a minimum and a person with strong computer knowledge may easily be able to get around this hardware based security.

Another criticism that has been made about these hardware based encryption systems is the fact that the vendors who manufacture this hardware do not publish how the encryption itself is done. This secrecy leads to the potential customer possibly buying hardware that they know literally nothing about, including how well the encryption system performs. This aspect of the manufacturing of these hardware systems can also lead to vendor lock-in, which means that the customer is locked-in to purchasing all products and services from the vendor who designed that hardware. This policy prohibits the customer from comparative shopping for these products and forces him to pay whatever price the vendor is asking.

Vendor lock-in can also affect the compatibility of the hardware based encryption with other equivalent components. For example, your hardware based encryption system may be inoperable with other systems such as the application program or the file format unless these programs are also designed by the same vendor. These hardware systems may not work with other operating systems either. These prohibitions enable one particular vendor to corner the market for the technological needs of your company.

Another problem that a company may have with hardware based encryption is the high cost that is associated with installing and maintaining it. Many companies find that this hardware is just too expensive to be implemented into their computers.

Hardware based encryption is a good way to secure your computer data. However, you will need to decide if the high cost and risks associated with this hardware is worth it.

Surely, everyone has seen movies such as The Fast and The Furious and Torque. What are the two things these films have in common? The answer is speed. It doesn’t matter if one used cars while the other used motorbikes because this still gave the audience the thrill of what its like riding on the wild side.

Is this real? Can this really happen? The answer to both questions is yes and all it takes is calibrating the engine for these vehicles to be able for it to exceed more than an hundred miles per hour on the road.

The driver may not notice how fast the vehicle is going when sitting behind the wheel and the only indicator will be the speedometer located a few inches below the windshield. There are two types of speedometers. The mechanical and the electronic version.

The mechanical speedometer works using a cable, a rotating flexible shaft and a magnet. After calibrating and combining these three components, the speed of the car will continue to increase as one continues to step on the gas.

The electronic version also uses a magnet. The only difference is that in order for this to work, the entire system needs a computer. Once this is calibrated, it will be able to tell how fast the vehicle is moving.

Most of the cars use the electronic version but those who like to drive something like a 1956 Mustang will surely be able to reminisce the good old days when the mechanical speedometer made man and machine work together.

Unfortunately, driving more than a hundred miles per hour in the city or even on the freeway with the calibrated speedometer will only get the driver in trouble. For safety reasons, the police will most likely pull over the driver and issue a ticket.

This should serve as a lesson to the one behind the wheel because most car accidents are caused by over speeding or drinking under the influence that causes damage to property and may take someone’s life.

One ticket is ok but repeated offenses will make it more expensive to get insurance for the vehicle. At worse, no one will want to insure the individual given the reckless history that is a liability to the insurance company.

The best thing to do then with the calibrated speedometer will still be to follow the traffic rules especially the speed limits. This varies on city and highway driving but regardless where one is, the right thing to do will be to abide by it.

Today’s news article on computer forensics is about hacking encrypted Fingerprint USB drives. The encryption being talked about is AES 256 hardware encryption, which til date use to be considered a very reputable and safe standard in the world of digital and computer forensics. You must have seen online advertisements about the most secure hardware based AES 256 bit encrypted Fingerprint USB drives from popular brand names such as Kingston USB and SanDisk USB, these are the ones that have been found to be completely vulnerable by a computer forensic company based off Germany called SySS. Their tests show a major design vulnerability that can decrypt the present information on the thumb drive.

SySS is a German company that specializes in Computer and IT Forensics. In a nutshell how they are able to read encrypted data is very simple, it does not even require to put in your password. When a user enters their correct password on the key to decrypt the information, the hardware algorithm passes through a particular string of information or characters to the device storage system which presents the information to the user in clear text. The flaw however comes in with the fact that this “String” passed through after a valid session for any password, is always the same!

SySS used their computer forensic know how to interpret this “string” and were able to demonstrate how they can pass this on to the hardware device and get decrypted information every time. There are two White Papers published by the company on their website that explains this much in depth. This discovery has major implications on Corporate and Law Enforcement officials which often carry sensitive information on such encrypted devices. As a matter of fact, there is school of thought around which is debating if law courts will now accept hardware encrypted thumb drives as “unaltered” secure evidence.

There are 2 types of tv tuners for laptop computer, one is a hardware based solution and the other a software. Both will work just fine on laptops but they vary in terms of costs, number of channels offered and portability. These will be discussed in this article.

The first solution is to get an external PCTV card for your laptop. External PCTV cards come in the form of USB device. This tv tuner for laptop computer typically comes with its own proprietary software that enables you to stream hundreds of live television channels through wired broadband connection. A device like that costs a few hundred dollars and can be found at any major PC hardware stores.

The other tv tuner is a software known commonly as satellite tv software. This software when installed, gives you access to thousands of channels worldwide in different languages. It streams live satellite channels through internet and works on both wired and wireless broadband connections.

Both solutions only require a one-time cost which is for the purchase of hardware/software. However, it is interesting to note that a good satellite tv software will cost you no more than $50. Furthermore, it can offer more than 3000 channels on a standard package.

In terms of portability, majority of PCTV cards require a wired connection whereas wireless connections work just fine with satellite television software. That means you can be watching a football match or favorite tv serial in a cafe or anywhere in the world with a WIFI connection. Personally, satellite television software is, to me, a preferred tv tuner due to its portability.

Before you purchase a PCTV card or satellite television software, it is good to make sure they are supported by the operating system of your laptop. Windows Vista or Windows XP should be fine but if you are running Mac, it is good to check with the product merchant or read the FAQs before making a purchase.

Microsoft has designated 2 levels of compatibility for the Windows Vista release. These 2 levels refer to hardware that will support Windows Vista to varying degrees. These levels are designated Windows Vista Capable and Windows Vista Premium.

Windows Vista Capable PC

Windows Vista capable, means that your present hardware meets the absolute minimum requirements install and run Windows Vista.

  • A modern processor (at least 800MHz).
  • 512 MB of system memory.
  • A graphics processor that is DirectX 9 capable, with a minimum of 64mb of RAM.

Windows Vista Premium Ready PC

A Windows Vista Premium Ready PC, means your hardware meets the minimum requirements to use most additional features of Windows Vista that enhances the user experience. In other words, the higher minimum requirements will improve the system performance and enhance advanced media such as Windows Aero. These are the recommended minimum requirements.

  • 1 GHz 32-bit (x86) or 64-bit (x64) processor).
  • 1 GB of system memory.
  • Support for DirectX 9 graphics with a WDDM driver, 128 MB of graphics memory (minimum), Pixel Shader 2.0 and 32 bits per pixel.
  • 40 GB of hard drive capacity with 15 GB free space.
  • DVD-ROM Drive.
  • Audio output capability.
  • Internet access capability.

Summary

The biggest difference between Windows Vista and Windows XP are the system memory and video requirements. Windows XP will run well with 128 MB video card and 1 GB of system RAM. Ironically that should be considered the minimum to install Windows Vista.

Windows Vista is much more graphic intensive than Windows XP and creates a richer media experience. Of course these requirements increase the cost of hardware needed to run Windows Vista. For those who have been dragging there feet on the video and RAM front have the media creators and PC gamers to blame for the extra cost.

If you have read some of my other computer articles or guides you will already know that I never recommend using advertised minimum hardware requirements. When you read the words “minimum requirements”, the bare minimum is what you get. Any time you upgrade a PC to the minimum recommended requirements the results will always be a disappointing.

With that in mind, my recommendations for installing Windows Vista are the following.

Recomended

  • 2 GHz +, 64 bit or Duel Core processor (Intel Duo Core or AMD X2 for Gaming)
  • 2 GB +, of matching system RAM
  • 256 MB +, ATI or nVidia graphics card (not integrated on board)
  • 40 GB +, Hard Disk (15 GB free space required for Vista install)
  • CD-DVD ROM
  • Other required hardware should be obvious.

Take note that video integrated on to the motherboard is NOT recommended. Integrated video uses system RAM which robs your system of resources and increases your memory requirements. Also there are add-on video cards that use system RAM and have very little memory of there own. When buying an add-on video card read the memory specifications very carefully.

Windows Vista will run smoothly on a PC meeting these recommendations. Most users will only need to upgrade their video card and add system RAM. Windows Vista supports most of the same hardware that Windows XP supports. Motherboards, Modems, Ethernet, Hard Disks and other common hardware in use today are supported.

Remodeling kitchens often involves upgrading kitchen cabinets. Don’t overlook an important, although small, feature that will really give your new kitchen cabinets a finished look – the hardware.

Cabinet door hardware is a necessary item when installing kitchen cabinets, but more than being just necessary, it can also be very decorative. And after all, as long as it is being done anyway, shouldn’t it look as nice as it possibly can?

There are several types of cabinet hardware available. Hinges, door pulls, door knobs, and drawer pulls are the items that can be readily seen and can add that decorative touch when installed.

Keeping in mind your overall theme for the room, you have many choices in color and design of cabinet door hardware. Black, gold, silver and pewter are common colors for cabinet hardware although many other colors like blue and white are available for more colorful choices. Designs are even more varied, from plain and unobtrusive to ornamental and showy. With some careful consideration, you can choose hardware including hinges, pulls or knobs for both doors and drawers that will match each other and be complementary to your kitchen cabinets.

Let’s start with hinges. The hinges on your cabinet doors can be invisible if you wish, or seen in part by using half surface hinges. The type of hinge you choose may depend in large part on the type of cabinet doors that are being installed. For wood doors, the choices of hinge are many. Strap hinges, dummy hinges, butterfly and colonial hinges are just a few options that will make your search interesting.

Door pulls and drawer pulls bring a bit more of your creativity into the selection. Do you have a theme in your kitchen? Or do you have a passion for a particular item or design? Door pulls and drawer pulls are one area where you can bring a truly personalized look to your kitchen cabinet hardware. For a rustic cabin look, choose pulls that look like twigs or evergreen trees; or maybe you’d like to bring moose, wolves, or bears into the kitchen for a touch of wildlife décor. Celtic, shaker, and California styles add different looks that can accent the style throughout your room. Maybe you wish to stay in a kitchen minded theme, and want to add door pulls and drawer pulls resembling silverware or teapots.

Door knobs are the truly fun part of choosing new cabinet hardware for your home. With designs and patterns that will truly exhibit your personality and tastes, door knobs are extremely visible and of high use on your kitchen cabinets. Coordinating with your overall theme in the kitchen, your possibilities are seemingly endless, with countless choices of food, animals, objects, shapes, and designs at your disposal. Simply choose your style, and have fun!!

Decorating with cabinet hardware is not limited to your kitchen. Every room in your home has some type of cabinet, and every room may have a theme or design that you can carry through to display on the cabinets. Use cabinet hardware to add a finished look to the cabinets in every room of your home.

Author Jennifer Akre is an owner of a wide variety of online specialty shops like http://www.eknobsandpulls.com/ that offer both items and information on how you can easily furnish and decorate your space. Whether it’s your living, bedroom, or even your deck or patio, there are many tips you can use to make those spots both functional and beautiful. Today, she offers advice on how to create a fabulous living area by using charming cabinet hardware to define your cabinets.

Computer hardware software are two opposing components that make up desktop computers and notebooks. They work together in harmony to allow the user to operate his or her electronic device. However, they are completely opposite in their functions and abilities. It is essential that you understand the difference if you want to operate any such electronic device.

These two must work together and work properly or the machine will be nothing more than an expensive paperweight sitting on your desk. In this article we will discuss the differences between the two and how they function together as a cohesive team.

Computer software is different than hardware in that these are the programs, procedures and documentation that cause the machine to be operated by the user. The software is classified into three different categories. The first is system software.

The system software helps the machine run. The second class is the programming software which allows the programmer to write new programs. The final category is the application software. The application software is any non computer related tasks.

Desktop computers and notebooks consist of tangible products that cause the machine to run. These include any memory modules such as RAM (Random Access Memory), mouse, keyboards, and all circuitry components within the machine such as mother boards, sound cards and video cards.

Even your power source is a vital asset that makes the machine run. The term “software” can be attributed to John W. Turkey in 1958, though there were earlier essays and theories dating back to the 1930s.

Computer hardware software works together. The software is loaded onto the hardware so you see how vital each system is and how they must work together for the computer to operate. This is especially important in the case of memory modules. Without both components you would have a machine that could not run or a machine that could not access memory.

Computer hardware software works together and you must know that your computer memory software is loaded directly onto the RAM chips. How much information is stored and how fast the computer can access the information is determined by the software working in tandem to store the information onto the hardware.

Most users never have to worry about the software outside of installing certain programs onto their computer. The same goes for the hardware. Outside of the keyboards and mouse, you really will only need to worry about system requirements and storage.

Last One Home Rock on. Chill out. Get funky. All on the one, great album. – Doyle Smith – Brisbane, Qld, Australia
Nothing but absolute praise for Andy Spence’s fine work on Last One Home. I first heard “Play to the Music” and couldnt stop rocking (it has a small part in the movie Swordfish) and then I heard “Nurega” on the movie the Fast and the Furious and when I realized they were by the same creator, I knew the album would be magic. Like electronica that can be funky and chilled? You’ll love this effort.
Warm, immaculate, moving forward, and funky as all heck, Organic Audio (a.k.a., Andy Spence) raises the Tummy Touch label (Groove Armada, Tim “Love” Lee, Mescalito, Tutto Matto to name a few) and its banner ever higher in the sky for all to see. “Last One Home” is brilliant funk for the 21st Century. If you haven’t been turned on to this outfit, hit the buy button and let the hip-shaking begin. It will be a shame if this release doesn’t find its way into the ears and pants of as many listeners as possible. It is undoubtedly one of the brightest, fun grooves to happen in some time, beginning to end. Have faith, my dancing brethren, you will not go wrong with this or any of the Tummy Touch releases. Purchase with bottom-shaking confidence. : Last One Home by Organic Audio

This product is manufactured on demand using CD-R recordable media. Amazon.com’s standard return policy will apply.

Are you looking for a computer monitor? Monitors are your window into the computer – everything that happens in your software and applications happens via the monitor. It is hence very important to choose a good monitor to go along with your new PC.

Traditionally, CRT (cathode ray tube) monitors have been used for desktop computers. However, these days, LCD (liquid crystal display) monitors are selling like hotcakes. It’s easy to see why: LCD monitors are easier on the eyes, have very crisp image quality and yes, they’re sexy and cool. Laptops also use LCD screens – so we’re slowly beginning to see CRT monitors being phased out.

Which type you choose depends on your requirements. If you’re a graphics professional, you may prefer a CRT monitor because they are said to show more realistic colors. However, the latest high-end LCDs can also give equal color quality. If you with text most of the time, a LCD is a good choice because the various pixels that you find on a LCD will have nicely defined edges. This gives sharp and focus letters on the screen.

To help you choose a monitor that’ll meet your needs, this article will step through the factors to consider when buying a LCD or CRT monitor.

LCD Monitors


    Let’s first look at the various factors you need to think about when purchasing a LCD panel display.

  • Panel Size: In an LCD monitor, the panel size reflects the viewable area you can use. Again, the measurement is made diagonally from one corner of the screen to the opposite corner. LCD panel sizes now range from 15 inches up to 23 inches.
  • Native Resolution: An LCD panel display always has a certain native resolution. Usually you can go lower than this resolution but the image will appear blurry. If you need to change your monitor resolution quite often, then a CRT monitor may be a better bet. LCD native resolutions currently range from 1024 by 768 to 1600 by 1200.
  • Viewing Angle: One problem specific to LCD monitors is the fact that you cannot see what is displayed if you move off to the side of the monitor too much. A greater viewing angle is therefore typically better – especially if you need to show presentations to others on the LCD screen very often.

CRT Monitors

Now let’s take a look at some things you need to look out for when purchasing a CRT monitor.


  • Tube Size and Viewable Area: The tube size and viewable area of a CRT monitor is of utmost importance. The tube size helps you judge how much room you’ll need for the monitor on your desk. It is expressed in inches measured from one corner of the monitor to the opposite corner.

    The viewable area (also measured diagonally) indicates how much you’ll be able to see on a screen. The viewable area of CRTs can range from 15 inches all the way up to 22 inches.

  • Tube Type: You’ll need to think about tube type as well. Traditional CRTs have curved screens, while newer models usually have flat screens. Flat screens improve clarity and reduce glare, so you should think of getting one if you want to reduce eye strain and fatigue.
  • Maximum Resolution and Refresh Rate: A CRT monitor’s maximum resolution can range from 1024 by 768 at 75 Hz all the way up to 2048 by 1536 at 70 Hz. For normal home use, 1024 by 768 at 75 Hz is sufficient. Try to ensure your CRT monitor supports refresh rates above 70 Hz – anything below 70 Hz can result in screen flicker and cause eye strain.
  • Dot Pitch: The dot pitch of a CRT monitor helps you determine how sharp a picture will be – these can range from 0.24 mm to 0.28 mm. A smaller dot pitch number often indicates a sharper image. Of course, to the untrained eye, the differences in image quality due to dot pitch may not be discernable. Hence, the dot pitch may not be an important consideration if you’re not too concerned about the finest details in your screen images.

Conclusion

I hope the above has helped you understand what factors to look out for when buying a LCD or CRT monitor. One thing to always remember when buying a new monitor – don’t throw away your old one! Re-use it for an old PC or give it to a friend who needs one. By not dumping that old monitor, you’ll certainly help to save the environment.

So, you think you’re ready to build your computer. Well congratulations. What took you so long? It’s not difficult at all, but there are several things you need to be aware of. Let me help you in building a computer from the bare-bones.

There are a few questions you need to ask yourself when building your own computer. The first and most important question you need to ask yourself is:

What do you ultimately want your computer to do? You may want a computer that will allow your children to do basic word processing functions for homework and internet surfing for research and instant messaging for communications. You might just as well want a computer to handle extensive video editing projects or maybe you are in to serious computer gaming. The point is, by answering this question, you can begin to focus specifically on what type of parts best meet the needs of your project. It will also answer the next question you need to ask yourself.

Do you need to build a high or low end computer? If you need a computer to do basic computing functions, I recommend you buy parts geared towards building a low-end computer. You may want to get a dual-core processor (CPU) instead of a quad-core. You won’t need as much memory. A good 1GB will be more than enough. By following these two examples you will have already saved yourself over a hundred dollars. On the flip side, in building a high-end gaming computer, you not only want power, but beauty as well. Instead of a plain computer case, you might want to buy a case with plexiglass siding, to show off your innards.

Great, that’s taken care of. Now I am going to answer a question that may have entered your mind at some point in your thought process about building a computer. You are probably wondering where to buy the parts for the computer at? I suggest, unless you have a computer super store in your area, buying your components online. This is your best bet at finding a variety of options with great pricing. I’ve gathered a pretty extensive list of computer parts and electronic online stores that offer great prices at http://pcbuildersdelight.synthasite.com.

Ok, you’ve figured out what you want your computer to do, what type you need to build and where to buy the parts. You are well on your way to building your computer. Now you need to know what to buy. This step takes a little bit of research if you are planning on buying every part individually. One alternative and an excellent one I might add for novice builders is to buy a bare-bone system. This will take the guesswork out of parts compatibility. A good one for starters will be one that has the PC case with power supply, the motherboard, the hard drive, the CPU, the memory and the video and sound cards if needed. Keep in mind, the lower the cost (for the most part), the lower the performance.

The first computer I built took a long time, not because it was hard to put together, but because I kept buying incompatible parts. The CPU was not compatible with the motherboard. The voltage in my memory was too powerful for the motherboard to interpret it. My hard drive was 150 instead of the needed 300. I’m not getting into great detail of what all these compatibility issues actually are, because I really suggest that you start off with a barebone system. This way you can focus on the build instead of the frustration of compatibility.

So there you have it. Start off by asking yourself a few questions. Check out the site for the different online stores. Finally, try barebones systems to eliminate compatibility issues. Happy building.
