Everyone with a computer is looking to have the fastest, and most efficient computer filled with the latest computer hardware technology. But to keep up with the continual changes as technology becomes more and more advanced requires complete upgrades on your computer. But, what are the best computer upgrades available?
Memory Upgrade
A memory upgrade is one of the most popular computer hardware upgrades and one of the easiest to do to boost the performance of your pc. But before you do a memory upgrade first check the BIOS operating system to determine how much memory is already on your system.
Also to upgrade your memory it will be necessary for you to open the case of your computer to find out how many modules are currently installed and how many slots are still empty. If all the slots are already filled you may have to remove the modules and replace them with larger ones.
Now, after finding out the current memory situation, review your operating system and application programs to determine how much memory is needed to make your computer perform at its peek level. In general, these programs provide a minimum and a recommended rating. So to reach the fullest potential of your computer, the memory should meet or exceed the recommended level.
Ok, so you now have some basic information to do your memory upgrade, but hold on a second, before running out and buying more memory, check your computer manual or go directly to the motherboard to find out what type of memory is supported by the current computer operating system. If you don’t check this out you will most likely get the wrong memory chips and the memory upgrade will not work.
Also keep in mind When buying a memory upgrade module, that it is best to buy the largest amount of memory with the least number of modules. This way, there is room for growth in the future. For example, instead of buying two 512MB modules, purchase one 1gb module.
Video Card Upgrade
A video card upgrade makes it possible to play all of the great games that are currently available on the market. In fact, some games are so advanced that they won’t play at all without a very powerful video card.
But it can be tough choosing the right video card since there are literally dozens available. It is very important to first take a look at the motherboard to determine what type of video cards are supported by the system, you can also check your computer manual on the types of video cards your system will support. The best video cards are the ones that transfer data the fastest. In order from the fastest to slowest cards are PCI express, AGP 8x, AGP 4x, AGP 2x, AGP and PCI.
Sound Card Upgrade
The sound card improves the sound produced by the computer. This makes computer gaming more enjoyable, as well as listening to music and watching digital media.
In order to install a sound card, you need to locate an available ISA slot on the back of your computer. These slots are the longest sockets on the motherboard and there might be other cards already installed in those sockets. There are two internal openings on each of the slots at the back of the computer. So, remove the access plate at the rear of the socket to insert the sound card. Make sure the access plate on the sound card covers the hole created by removing the initial access plate. But, be sure to gently insert the sound card with a slow back and forth movement, otherwise the sound card can be damaged.
DVD Player/Burner Upgrade
With so many digital videos becoming available, many people are looking to upgrade to a DVD player and burner combo. The most powerful DVD player/burner currently available is the DVD+R/RW. These do tend to, however, be incompatible with older DVD-ROM drives and DVD players. But the current big names in the industry, such as Sony, HP, and Phillips, support these players. DVD+R/RW drives are faster than previous models and are capable of formatting while burning data to the disc.
Motherboard Upgrade
Now for those of you who are truly serious about upgrading your computer hardware, motherboard upgrades are another popular option. But of course, a motherboard upgrade is the most difficult upgrade to do and I certainly wouldn’t recommend it if you don’t have a strong background in computers and electronics. For those of you who can manage, however, you will certainly enjoy the freedom of never having to buy a new computer. Instead, the motherboard can be upgraded as technology advances.
In addition to eliminating the need to buy a new computer, a motherboard upgrade also makes it easier to upgrade other components on your computer. This is because purchasing a motherboard ensures receiving the most up to date technology, which is then compatible with other upgrade components.
Upgrading the motherboard, however, requires serious advanced planning and reading of your computer manual. If you don’t do this correctly, your computer will be nothing more than a huge paperweight. If finished correctly, however, the computer will remain on the cutting edge of current technology.

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.
