Are CDs And DVDs Still Good For Data Storage?

Both CDs and DVDs offer simple yet safe way for data storage important data without any expensive investments. Let’s take a closer look at how they may be used, and which safety issues may arise when using these optical storage devices for backup.

Benefits Of Using Either CD Or DVD For Data Storage

Once so popular CD (Compact Disc) and its writable versions CD-R and CD-RW have been available for quite a while. First CD-R recorder was produced at the end of the eighties, first Yamaha CD-R recorder cost about $35,000. Technology becomes cheaper over time and, now, the same recorder costs about $20. Although DVD (Digital Versatile Disc) came into use a little bit later, it still hasn’t completely replaced CDs. There are even more advanced technologies available today, like higher definition DVDs, called Blu-Ray, but they are aimed at quite specific use cases and will probably not become mainstream, since newer technologies are taking over.

It is widely known that DVDs hold about 6 times more data than CDs but it does not mean that CDs are obsolete. The great thing is that both CD and DVD reading and writing devices have become more versatile, making it possible to use different discs in the same device. Since both are so widely used, there is no danger that CD or DVD readers will disappear.

Cheapest Of  All Mediums

One of the benefits of using either CD or DVD for data storage is their cheap price. When buying CDs or DVDs in bulk, one DVD-RW disc might cost only 40–50 cents. Discs that are not rewritable are about three times cheaper. It means that the data storage of one Gb of data will cost you only 3 cents (DVDs store 4.7 Gb of data). As history has shown, the cost of data storage can only get cheaper.

CDs and DVDs, also known as optical discs, are easy to carry around, and you can easily relocate them. They offer a simple and cheap way to protect your data from fire, theft and other local accidents. Certainly external hard drives, flash memory cards and USB sticks also serve the same purpose but they are many times more expensive.

To choose the right data storage medium for your data, you also need to consider a particular medium’s reliability. What are the risks related to CDs and DVDs? They are popular among users because if a CD is accidentally dropped, it usually works fine afterwards, which can not be said about external hard drives. This fact is especially true if CDs are data storage in protective case. Optical drives are technically quite different from hard drives and can not be damaged by strong magnetic fields.

Greatest risks related to CDs and DVDs

Some sources mention damages caused by direct sunlight and high temperature. Even more problematic is that CDs are extremely vulnerable to scratches. One deep scratch may damage a disk to the extent that it becomes useless. Keeping disks in protective sleeves or in strong boxes is the safest practice. Many experts have expressed their concern about optical disks’ long-term reliability. Sure, they haven’t been around more than a few decades but in our experience CDs with fifteen-year-old data on them are still working pretty well.

The capacity of DVDs and CDs might not be the best for data storage a massive number of raw image files and movies, but they are still worth considering if you need to make backups of your important everyday files and folders. Keep your discs protected from scratches, avoid direct sunlight, and you can definitely use your valuable data for decades from now.

The Importance Of WordPress SEO Today

When you look to build an audience online today, you will find that it’s harder than you may have thought. The reason for the difficulty factor rising is that more and more people are putting their stamp on the internet. WordPress has become easier than ever to start a website, blog, or any sort of promotional item on the net. Instead of having to know a lot of code, anyone that can navigate through a few menus can have a domain name and site running with relative ease. WordPress is that saturation that is causing a great deal of changes to the blogging world, and more so than ever before, WordPress seo matters.

Importance Of  WordPress SEO


For those that aren’t familiar with the terminology, it is simply an acronym for the terms search engine optimization. This process helps connect websites with search keywords online. When someone goes to search for just about anything, they will get fed a list of websites that are closely related to the topic, and if they find the right option, they will click through and end up finding what they are looking for. This is done through proprietary algorithms that technology companies keep close to the chest. They do not give people insight into what factors play a role, however, that’s where seo comes into play.

When you set up a blog using WordPress, you’ll have one powerful content management system. Within that system you can add extensions known as plugins, and those can help you gain merit within search platforms. The way it works is through the optimization of pages. These pages can be filled with contextual information, that is 100% unique, but has something extra. That extra is the concentration of keyword phrases which are picked up by search platforms and delivered to users that are looking for specific information on just about any topic you can think of.

The biggest thing that you have to remember about searches that are conducted through large websites, is that they are there to answer questions. If you have a product, service, or blog that can answer that question, you will get the traffic. However, if you’re 1 of 1 million websites that does that, you will need to offer a bit more than just the answer. It’s there that wordpress seo can save the day. By making sure that pages are optimized up to par with the standards of the online world, you will get a major return on investment, getting serious traffic that is not only great in numbers but hyper targeted.

Getting targeted traffic is the difference between success and failure on the web. Creating the opportunity to get seen on the net today is a matter of working within the parameters of seo properly. If you do not work with the rules, you will have a hard time finding yourself in the index of any major search campaign. Instead of paying thousands of dollars for marketing, you can easily save money and utilize specific optimizations that will help get you ahead of the competition, even if you’re a new website.

The Advent Of Google Glass

The latest invention from the wise minds at Google has hit the market and is beginning to make its way into mainstream America. The initial model is available in America as of February 2013 for the steep price of $1,500. That is a price, though, that many are willing to pay to have the latest and greatest technology from arguably the most innovative technology company on the planet. Google Glass is an astounding piece of technology that takes the idea of the personal computer and then turns it on its head.

What Is It & How Does Google Glass Work?

Google Glass, simply put, is a computer that you wear in a pair of eyeglasses. What? That’s right, it’s a computer so small that it can be worn. But why eyeglasses? Well, the device operates largely off visual and audible cues. For instance, photographs can be taken merely with the blink of an eye, and simple spoken commands can prompt it to perform various actions. What is truly innovative about Google Glass, though, is that it is connected wirelessly to the Internet, and can transmit data to cyberspace instantaneously.

The Revolutionary Effect It Will Have on the World As We know It


The future of Google Glass is bright, and it can only improve from here. As of now, Google Glass has a storage capacity of only 1GB, and that is certain to expand with time. Also, Google Glass is presently only available in eyeglasses produced by Google. However, deals are currently in the works between Google and leading eyeglass manufacturers, including Ray Ban, to have Google Glass implemented seamlessly into a standard pair of glasses. Google Glass is still in a primitive stage, and we can only expect innovation to take over from here to make the device even smaller, faster, more efficient, and, of course, less expensive for all to use.

The Seattle Bar Incident

Really, there wasn’t an incident at all. However, a bar called The 5 Point Cafe in Seattle, WA, made headlines by banning Google Glass before it even hit the market. It comes as no surprise that the initial grievance with Google Glass was from the tech-savvy city of Seattle. The bar’s owner asserted that The 5 Point Café is a dive bar where people go to be themselves and not have to worry about the pressures and stresses of the outside world. In fact, the bar’s slogan is “Alcoholics serving alcoholics since 1929.” The owner went on to say that he did not want to have his patrons subjected to a device, almost unnoticeable, that is capable of streaming video and taking photographs and having them posted to the Internet instantaneously, and declared his bar to be a “No Google Glass zone.”

The Potential For Similar Situations to Arise

That bar in Seattle certainly won’t be the only business to find fault with Google Glass, and there are a number of reasons why. Movie theaters almost certainly will not want to have individuals view a film while being able to record it in a nearly undetectable fashion. Similarly, other businesses may want to preserve privacy for customers and decide to ban Google Glass because it can potentially infringe on privacy.

Legal issues will likely follow, but Sergey Brin, Larry Page, and the rest of the crew at Google are prepared to take on whatever may arise in the future. What it really comes down to is whether Google Glass will do more harm or more good, and as of right now, Google Glass promises to be a computing innovation that could transform life as we know it.
