Refurbished Electronics Advantages
Refurbished Electronics offer great savings. However, they come with a shorter warranty. New electronics can be very expensive; but they come with a longer warranty. It really comes down to your personal preference.
Refurbished electronics advantages are too numerous to list in this single article. The price difference between new electronics and refurbished ones is probably the most important of all the advantages of refurbished electronics. However refurbished products do have their disadvantages also. -There is no benefit without cost and there is no cost without benefit.- We do not know who made this statement; but we know it has to do with economics.
This economics principle stands true when it comes to refurbished electronics advantages and disadvantages. Should you buy brand new electronics or refurbished electronics? Obviously, that is a question only you can answer.
In spite of the great price benefit that comes with buying refurbished electronics, some people still prefer to buy brand new even if that means more debt. Others would prefer to save the money and buy only refurbished electronics. It is all a matter of personal preference and opportunity costs. The best we can do is to point out some of refurbished electronics advantages and disadvantages. Refurbished Electronics: Advantages and Disadvantages
1. Refurbished electronics can be up to 80% cheaper than new ones. For example, a refurbished Samsung HP-R4252, 42- Plasma HDTV with turner and all the bells and whistles costs about $750.00. A new one costs about $3,200.00. That is a 76% off from the original price.Clearly these are some great refurbished electronics advantages.
2. If you were to add $249.99 for a 3 year extended warranty onto the already discounted price ; you would pay roughly one-third (1/3) of the original price. That is, [($750.00 + 249.99)/ $3,200.00]X100= 31%, roughly 1/3 of the price.
3. Refurbished electronics sport the exact same technology as new ones.
4. Other refurbished electronics advantages come in the form of reliability. These products are rigorously tested for optimum performance. They must meet the same factory specifications as new ones.
In our opinion, there is one disadvantage with refurbished electronics – the manufacturer warranty. You only have a 90-day warranty on refurbished electronics instead of the standard 1-year warranty.
While some people may fuss about that, we believe it is a fair deal. Since the refurbished item has been thoroughly tested and met factory specifications, nine months worth of warranty is served through the refurbishing process.
However, if you insist on having a longer warranty you can buy an extended warranty for 3 to 5 years ranging in price form $30.00 to $150.00 and up respectively. Note that even with the added extended warranty you still save a boatload of money.
So, buying refurbished electronics give you the opportunity to own a high end, late model electronic gadget without swiping away your life savings. Way to go! Buy refurbished electronics!
New Electronics: Advantages and Disadvantages
There is only one advantage in buying brand new electronics – The warranty. Unlike refurbished electronics, new items are sold with a 1-year warranty. You can buy a refurbished electronic, then buy an extended warranty for the peace of mind. You will still have a better deal.
The one year warranty that comes with the new item makes perfect sense. Manufacturers do not test every new product. They simply test a sample from a batch.
If the percentage of successful tests satisfied a pre-set standard; they assume that all products from the batch will work. The truth is there is no guarantee they will. That is why they give a full year warranty on them.
New items are only randomly tested. So they are susceptible to breaking down. For this reason, a longer warranty is offered on it. It is clear that refurbished electronics advantages outweigh new electronics advantages.
Our advice is simple; you don’t need to work your life away for a one year warranty. You can enjoy a greater peace of mind if you buy an extended warranty on refurbished electronics. Just remember:
Refurbished electronics are tech
[Top]History Of Sony Consumer Electronics
Apart from looking at simply the corporate world of Sony consumer electronics, there is much more to Sony consumer electronics that makes it a leader in consumer electronics. This innovation comes with Sony not just simply recreating products, but actually inventing new technology.
The name for the electronic company Sony was created by combining “SONUS,” the original Latin for “SONIC,” meaning sound, with “SONNY,” denoting small size, or a youthful boy. It was chosen for its simple pronunciation that is the same in any language. So why is Sony one of the greatest consumer electronic manufacturers?
Since 1946 Sony consumer electronics has been committed to bringing the world the best in technology. Even though Sony consumer electronics has been around for many years, the original Sony consumer electronics was actually called – Tokyo Telecommunications Engineering Corporation or more commonly Totsuko. It was only in January 1958 that the company changed its name to Sony Corporation after taking “SONUS,” the original Latin for “SONIC,” meaning sound, with “SONNY,” denoting small size, or a youthful boy. So, the name Sony was used because of its ease of pronunciation in any language!
In May 1960 – Sony consumer electronics was the first company to create the world’s first direct-view portable TV. The TV8-301 the world’s first non-projection-type portable transistor TV set comprised of 23 transistors and 19 diodes, this model was developed based on Sony’s extensive experience in radio technology. In an age when television sets were assumed to be living room fixtures, this device opened the door to personal television use. Additionally, the TV8-301 model offered three choices for power input.
Sony consumer electronics didn’t stop there, in fact Sony actually moved ahead and innovated more and more. In 1967 they invented the world’s first IC radio, and in 1968 Sony brought us the marvelous Sony Trinitron by releasing the KV-1310 to the masses. Sony has been leap years ahead with its electronics in television sets. And the Trinitron technology has filtered through the years, getting better and better to ‘WEGA’. Sony now brings us the Bravia range of high definition television sets. In fact the Sony Trinitron was such a major breakthrough in TV technology that in May 1973, Sony became the first Japanese company to receive an Emmy for developing the Sony Trinitron color TV system.
There are so many new products that Sony consumer electronics has brought us, which we did not have before. The Walkman is probably on of the greatest inventions from Sony. Before Sony consumer electronics invented the portable Walkman, there was no practical way of going for a Jog with music playing. Sony also brought us the world’s first compact disc player also, which is something we see included in our home computer, our HiFi system, and our car!
The Sony Playstation is another breakthrough. The Sony Playstation range has gone from 1 to PS2 to now PS3 and it looks like Sony consumer electronics will continue to make breakthroughs in the console market. The Sony Playstation is not quite a PC, but its specs make it pretty close.
[Top]Computer Forensics Chain Of Custody
As the trend for high-specification mobile phones and computers continues at a rapid pace so too does the potential for electronic media misuse and abuse. This kind of fraudulent activity is becoming more commonly seen in legal cases, particularly with employment tribunals. Legal firms are beginning to employ the services of computer forensics experts more widely in documenting electronic evidence and providing litigation support, as this can be crucial in the outcome of cases.
Computer forensics can be used to track and provide evidence in cases of intellectual property theft, money laundering, hacking, moonlighting and the accessing of illegal or inappropriate websites. Digital forensics can also help to secure concrete evidence of illegal activity not usually associated with electronic devices including blackmail, drug dealings and abusive behaviour.
Regardless of whether digital forensics is being used in a criminal case or a civil matter (even as part of an E-discovery exercise), maintaining chain of custody is vital. This is the fully documented tracking of evidence for the period of time that the forensics team has possession of an electronic device. It ensures that each member of the team can be held accountable for any action that they take with the media.
The purpose of this chain is to log the movements of the data, how it has been stored and subsequently analysed. It is essential that this documentation presents an accurate description of any copying, transportation and storage that has occurred, to prevent any potential legal challenge.
It is worth pointing out the differences between e-discovery and computer forensics. E-discovery is the method of processing and manipulating electronically stored information to be used in legal cases. This can take the form of emails, word processed documents, images and any other type of file, which can be filtered, viewed, analysed and categorised effectively via this system. E-discovery using a forensically acquired data set is crucial in maintaining the integrity of any information present, while potentially recovering any deleted material that may be appropriate for the legal proceedings.
Computer forensics is a highly complex industry that requires the latest in product knowledge and technical expertise. Specialists will have years of experience in the on-site capturing of data from computers, servers and other forms of electronic media. This data is then analysed by their forensic analysis specialists, and used to track how a particular device has been used. All areas of the chain of custody documentation will be completed to the highest standard to ensure peace of mind for the client.
[Top]Smart And Safe Automotive Electronics
We live in an age of information and technology that has made everything around us smarter. Electronic and digital components have made life easier in our homes, offices, and automobiles.
Some of life’s bells and whistles, like nose hair trimmers, are no more than budget-grabbing gizmos. However there are many intelligent tools that can bring convenience and safety to our daily tasks.
In the vast world of “smart” technology, the automotive electronics market is king. Indispensable features such as anti-lock braking systems and electronic stability control are perfect examples of smart and safe automotive electronics.
Recent developments by industry experts have created a huge increase in the number of electronic devices installed at automotive plants. Just to give you an idea of how quickly cars have evolved electronically, the Apollo 11 space craft traveled to the moon and back using a mere 150 kilobytes of onboard memory. It’s remarkable to think that the typical CD player uses a whopping 500 kilobytes just to keep our favorite songs from skipping. Listening to uninterrupted music is a mere iota of how electronics have impacted a car’s performance in order to benefit drivers.
Telematics is the term used for the technology that involves automobile communication systems. The term was originally used to describe the blending of telecommunications and informatics or information technology. This industry has been gaining more and more attention from car manufacturers over the past years. In the mid-1990s, industry insiders predicted that telematics would become “the” go-to technology; increasing overall sales and more importantly, transforming the automotive industry into a major player in mobile technology. In reality, these forecasts panned out to be less than what was predicted. From an initial industry projection of over $40 billion dollars, the figure has been whittled down to half as more conservative measures were considered.
Nevertheless, that is by no means an indication that the development of this telematics technology has been or will be abandoned. In fact, on average automobile manufacturers spend $2000 on electronic systems for every vehicle that comes off the line — in incredible increase from the $110-per-car budget of the early 1970s. This huge increase in spending is reflected in everything from engine performance to entertainment systems, security features to safety devices. Every component of the vehicle works together to provide automobiles that perform better, are more comfortable, and ultimately safer to drive.
Some of the most common smart and safe automotive electronics are as follows:
Controller Area Network
More than one computer runs your car. There is actually a network of computers called the Controller Area Network (CAN). Like a LAN (Local Area Network) that’s commonly used in home and business computers, the CAN links computers together. In your vehicle, the CAN basically links the many separate computer systems together and allows them communicate with each other. These interconnected systems involve everything from critical systems like engine management, cruise control and anti-lock brakes and cruise control, to less-demanding applications like automatic window and seat controls.
Fuel Efficiency
Skyrocketing fuel prices have forced automotive manufacturers to realize the need for fuel-efficient vehicles, and to meet that demand. Smart automotive electronics are used to create the more efficient burning of fuel, such as the electronic fuel injection system (EFI). The technology used in hybrid vehicles takes this one step further, with electronic devices that allow the driver to automatically switch between gas and electric engines.
Safety Devices
There are generally two categories of devices designed to protect the safety of the driver and passengers: active and passive safety devices.
* Active safety devices: These are systems that constantly work to ensure the safety of drivers and passengers. Examples of active safety devices are dynamic steering response (DSR), traction control (TCS), and acceleration slip regulation (ASR). While the average driver may not notice these systems at work, they are constantly sensing road and driving conditions and adjusting the car’s performance accordingly to create a safer ride. Electronic Stability Control has been shown by researchers to have a large safety benefit in reducing single vehicle skids.
* Passive safety devices: While these features may be more visible and seem simpler, they are also controlled by smart and safe automotive electronics. Thanks to developments in electronics and technology, airbag deployment has seen a tremendous amount of improvement over the years. Early airbags would deploy too early or too late, offering little or no benefit to the driver and passengers. Now, more advanced systems have created devices in your car that are actually programmed to the conditions that can lead to a high collision impact. Airbag and seating adjustment systems are deployed to minimize impact and decrease the degree of injury to the people inside the vehicle.
Think of the advancements over just a decade, and you’ll agree that the car of today certainly is a far cry from its predecessors. Modern automobiles offer more than simply a means of getting from point A to point B. Smart and safe automotive electronics make “getting there” as comfortable and as secure as possible.
