Cloud Services

Cloud services are now very famous among individuals and businesses. This has made it easy for users to access their files from anywhere in the world. A user with limited income may not buy a hard drive or any other laptop accessories but can get free storage online to keep data safe. With many options for the users, it is difficult to choose the best among many.

Cloud Computing ServicesAmazon Cloud Drive

Amazon is the leading cloud service in the world. It has the most users as compared to other cloud services. It gives users 5GB free storage, which allows users to upload and download any file. After the launch of cloud service by Amazon, they added a music streaming tab to allow users to listen to their favourite music. But later it was separated from cloud services. Users can now upload as well as listen to music on all their devices. The Amazon cloud drive is compatible with Windows, Mac, and Android devices. Amazon offers web based and as well as in desktop applications. The desktop application is compatible with all the operating systems but users can only upload files through this. For premium storage, 50 cents per gigabyte is charged and users can buy up to 1000 GB of space. Amazon services are cheap but not cheaper than others and desktop application compatibility and usage is another issue for the users.

  • Box

The box is not actually a storage service and is more suitable for business as it provides workflow solutions. If a business wants to share files, they simply grant access to a few users allowing them to view or download the files. Business productivity programs can be uploaded and integrated with the box where it becomes available to the users. Users can also edit the files if allowed. Box features business related applications and online workspaces. Box gives 5 GB of free storage and it is compatible with Windows, Android and Mac operating systems. To use this service, users must use the box sync application. For premium storage users need to pay $9.99 for 25 GB space per month but for businesses it offers 1000 GB for only $15 per month. For businesses, Box is a most suitable solid service.

  • Drop Box

Drop box was the most popular cloud service when introduced. And it was the first to have a large number of users. Cloud services were not used much before this. Drop box can run without a browser and it's compatible with almost all the operating systems including Linux. Due to its compatibility with all the devices, users have no difficulty in managing their files from anywhere. But the drawback is the limited space as it gives only 2 GB free storage. For the premium services it charges $99.90 per year for 100 GB. This is expensive as compared to other services.

In today's world, users don’t need to buy a cheap notebook or accessories like external or internal hard drives or flash drives. Rather they can use cloud services for the storage.

The Toshiba 450GB SAS Internal Enterprise Hard Drive Review

In its quest to bolster its resilient market position, Toshiba, who is one of the top brand names in the internal hard disc drive market, introduces a new power–efficient small form factor hard drive in the mould of MBF245LRC#LF 2.5–inch enterprise class hard drive.It is a high–performance, high–speed unit which comes with an industry mid–range storage capacity of about 450GB. Running at 6 GB/s of drive transfer rate, the SAS interface MBF245LRC#LF offers a 10,025 RPM of rotational speed, which is still about the fastest speed brought forth by a small form factor hard disc drive.

The new 450GB 2.5–inch SAS interface hard drive from Toshiba is amongst the enterprise family of computer hard drives that are ideally suited to power–conscious, business–critical and data–intensive storage apps including mainstream storage array, mid–range volume servers, and blade as well as rackmount servers. It is an OEM (original equipment manufacturer) drive that requires no screws, cables or software to run. The drive delivers low energy consumption benefits that are environmentally friendly.

In addition to this, the MBF245LRC#LF offers all the values of small form factor device allowing for more cost–efficient power consumption including a cooler form factor, a drop in sound levels, and better anti–rotational vibration performance. Mounting of this drive couldn’t be any faster and easier; the original 3.5–inch hard drives can simply be removed and replaced by inserting the MBF245LRC#LF 2.5–inch enterprise class hard drive in its place. As with the 450GB MBF245LRC, the frame is also available with the 300GB MBF230LRC and 600GB MBF260LRC. The form factor enterprise SAS hard drives are fully compliant with Restriction of Hazardous Substances (RoHS) regulation.

As the name of the device clearly states, the MBF245LRC#LF is the 450GB variant of the new Toshiba 2.5 –inch enterprise SAS hard disc drive line and along with which there are two other available models both in the mould of 600GB and 300GB storage capacities. With other manufacturers such as Seagate, Western Digital, Hitachi and the like already introducing one terabyte 2.5–inch Enterprise SAS computer hard drives, the MBF245LRC#LF seems rather small. In point of fact, even the supposedly largest Toshiba’s small form factor model in the MBF260LRC seems quite small compared to those.

On the contrary, Toshiba put performance atop capacity, thanks to a rotational speed of 10,025 RPM on the MBF245LRC#LF which simply outperforms the new 7,200 RPM hard disc drives by Hitachi, Seagate and others by a large percentage.

The MBF245LRC#LF weighs 1.09 lb, and measures 6.9 cm x 10 cm x 15 cm dimension wise. It is compatible and reliable with 32–bit and 64–bit Windows 7. Along with this, it is compatible with Microsoft Windows Vista and Microsoft Windows 2000 / XP. The unit comes with thirty six months manufacturer parts warranty.

The box contains 2.5–inch SAS enterprise hard disc drive in 3.5–inch LFF frame.

Advantages And Disadvantages Of New Technology

techWe have all seen new advances in technology that have amazed and astounded us. In the workplace technology is revolutionizing the way we do business. At home it is changing the way we view the world, the way we get information, and the way we entertain ourselves. And while new technology has many advantages there are also disadvantages; I will discuss both here.

In the workplace mobile and consumer technologies allow employees to work when and where they want. Many forward thinking companies are developing new strategies with these new technologies in mind. Those companies are reporting encouraging results. With over 70 percent reporting improved sales, and over half reporting improved returns.

As you can see, technology can be an important part of today’s workplace

However there are also recognizable disadvantages. One of the main problems with tech in the workplace is the risk of constant distractions. Emailing, web training, Skype, and cell phones can all be a recipe for confusion and distractions at work. Loss in communication skills is also a potential problem posed by technology.

As we tweet, Facebook, Skype, and email. We are not required to learn and use the listening, and social skills required in building professional relationships.

At home social media sites like Facebook and twitter help us keep up with family and friends, especially the ones we do not see very often. It allows us to express ourselves, and even make new friends.

Facebook is always there. On sleepless nights, or busy days, you can always log in to check up on loved ones, send a quick message or just entertain yourself. Facebook also allows us to connect with old friends, or people we thought we might never see again. While social media has many great benefits there are also negatives. Cyber bullying has been a frequent topic lately, with several severe cases reported with dire consequences.  Social networks can sometimes cause us to lose some privacy, and can cause us to waste time that could be used on more productive endeavors such as academics.

Video games have become a favorite pastime for many of today’s youth, and adults alike

Gaming can be a lot of fun and has several hidden advantages as well. Studies have shown that video games can improve young children’s motor skills. Video games can also be a great way to relieve stress.

Gaming has been shown to improve vision in people with cataracts. Researchers also believe video games can help improve decision making skills. Drawbacks include violent games that may be inappropriate for children. Too much time spent gaming can have negative effects on other areas of life, such a school. There have been reported instances of gaming addiction. One South Korean man recently died after spending 50 hours straight gaming without a break.

Reports show that 98 percent of the U.S. households that are online use social media sites

That 75 percent of the world’s population now has cell phones, and 68 percent of the U.S. households play computer or video games. These recent technologies are changing the way we live, work, and play. The way we communicate, keep in touch, reconnect and express ourselves. We are finding new ways to unwind, learn, and process information.

However, we may create new problems as we rely on new technology. A decrease in interpersonal communication skills, due to electronic communication, is a potential problem. We give up privacy, become over involved and perhaps less productive as we spend more time socializing, gaming, emailing, texting, and tweeting. It remains to be seen if new technology will move us forward or ultimately set us back.

The Best Apps for Printing on Apple and Android Mobile OS

The wireless world has quickly taken over and with it and things like google docs, we’ve started to lose the means of even caring about printing. Many companies even run with only one or no printers, and not everyone has one since most of our communication is online as well. That doesn’t mean we are completely out of the printing era though, paper or hard documents are still frequently used by the government and plenty of people on average. But that’s okay, because although printers have stayed mostly the same in terms of hardware for years, the software side of printing has evolved to keep up with demand and the times.

These days you can get all manner of applications for your mobile smart devices that not only allow you to print from them through wireless or Bluetooth means, but also do things like printing from a cloud or drive, and even scan images with the camera of your device to then print or upload to your cloud. And this isn’t even factoring in all the controls of a printer you can command through these applications by simply connecting to one wirelessly. So with that said; when it comes to printing applications, which ones are going to draw the best bang for your time?CubeX 3D Printer

Brand Specific App

There is always at least one official application for each printer brand out there meant for any operating system you run and when it comes to connectivity, these ones are likely your best bet, especially if you are running a newer model of a printer. Of course on the other hand, there can be a lot of downsides to the brand specific types. Generally, they come with poor feature inclusions, with many of them not even letting you set the quality of the image or even if you want the image in black and white. That doesn’t mean they are all terrible though, most of them tend to focus on image printing, and at that they are good, but not much else.

The major exception happens to be Brother’s printer application, which not only provides scanning capability, but can be used without a computer needing to be turned on, which is why if you are using a brother printer this one is your best option and for android or apple.

If you run an Epson printer though, you can get a few different features than the brother, like color to monochrome, communication and connection with things like evernote and google docs, or even draw files like web pages and PDF’s from the wireless connection of your Epson printer. Not the greatest, but still a steady selection for a brand choice.

PrinterShare Mobile Print App

If you are looking at something that has a bit more to offer in the features department then your best option is probably PrinterShare, which you can find for both apple and android. This pretty little app gives you the options of printing just about anything on your mobile device, from web pages to documents or pictures and even contact lists. It can also manage to connect to most any printer that is wireless (but works better with certain ones). Overall this app manages to provide the best selection of details you may want to change when printing like size and orientation, while giving the most varied ways of being able to print things. Unfortunately you can’t scan stuff with it, but considering you can access any picture you take with your device and print that, what’s the difference?

Oh, and did I mention this app is free? Well free so long as you aren’t printing regularly, then you’ll have to offer up some money for unlimited printing, but if you are needing to print multiple files a day, then you should probably be using a computer and not solely your mobile device.

PrintJinni App

This particular app has some major ups and downs when it comes to the overall usability. This mobile print program can do almost anything, including the printing of emails, pictures, word documents, anything in clouds or through Google cloud print, any major applications like Evernote and even social media like Instagram, Twitter, or Photobucket and even view pdf or documents without printing them on your mobile device. The downside? There are a lot of printers that it doesn’t support, like Brother, and most of all after thirty days of using it you have to pay monthly or yearly subscriptions to continue using the application. That might be worth it, if you really need all the features the program can offer, but chances are you won’t actually use half them unless your mobile device has replaced your computer completely. Otherwise this one is for android or apple and is probably one of the better ones to run with so long as your printer supports it.

ePrint Free App

Finally we have the one application in this list that cannot print documents contained directly on the mobile device. It can do photos fine, and even documents that are in the cloud, just not on the device. The real unique quality of this app comes with the customization elements, including being able to print out calendars or cards with your photos being used. This is why this one at least gets a mention, plus it comes with a lot of the same features as some of the other apps like being able to connect to a wireless printer without going through a computer, and probably the widest array of options when printing (considering you can make calendars). And best of all, if you aren’t worried about just printing one thing at a time, one copy at a time, then you don’t have to pay anything for this app either. Just be careful with an ink-jet printer as many of them are not supported by this app.

Overall you can find quite the selection of printing options, all meant to be customizable to what you might be looking for in printing and this application area for printing is bound to continue evolving over time to fit with our standards. It will only be a matter of time before you can scan the image of an object with your mobile device and send that message back to a 3d printer to make a copy of that.

How Does A Coaxial Cable Work

New advancements in technology are slowly wiping out what we once deemed as “amazing” in the tech field. Bluetooth, for instance, left many in amazement a few years back, but currently, Wi-Fi seems to be taking over in almost all aspects of wireless communication. While technology is indeed changing everything, scientists seem to have had a hard time shaking off coaxial/coax cables.

You’ve probably seen them before on cable TV, or on satellites. However, not many people really understand what goes on in a coax cable and even what’s inside the sheath.

Inside The Coax Cable

The outer plastic sheath that you see on a coax cable covers three components inside it including:
- Copper core
- Dielectric insulator
- Copper shield

Typically, the copper core is responsible for conducting actual electrical signals across the cable. On the other hand, the copper shield and the dielectric insulator reduce magnetic interference in the cable.

Signal Transmission in a Coax Cable

Signals are actually transmitted simultaneously on both the copper core and the copper shield. This is done so that both of these conductors generate their individual electromagnetic fields. These two electromagnetic fields eventually cancel out each other.

Once that happens, the cables can now be placed next to other sensitive electrical devices or even metallic objects, and there won’t be any worries about the cables acting like magnets and interfering with the signal in the copper core.

Besides that, the fact that these electromagnetic fields cancel out each other means that external magnetic fields will also be prevented to some extent.

Specifications For Design of A Coaxial Cable

Even if you have the four basic elements that make up a regular coax cable, it would be difficult to control other factors like attenuation, frequency, and the power handling capability of the cable.

The construction of coax cables goes beyond the four components that it is made of. Factors such as the physical size of the cable, the outside diameter of the inner copper conductor, and the dielectric constant play an important role in the functioning of the coax cable.

Choice of impedance is also crucial when it comes to design since it directly influences the attenuation. Bell Laboratories conducted experiments in 1929 and found out that the best coaxial cable impedances suited for high-voltage applications were 30Ω, 60Ω, and 77Ω.

Coaxial cables with air as the dielectric resulted in an impedance of averagely 77Ω. However, when more effective dielectrics such as solid polyethylene or polyethylene foam are used, the impedance drops to 52-64Ω.

Today’s coax cables can operate at frequencies of up to 2.4GHz, and that makes it worthwhile for use in Radio and TV industries. They were once used for implementing computer networks, especially in the bus topology, but twisted pair cables have replaced them.

All in all, coax cables earn their popularity based on the fact that they are good at transmitting signals at a considerably high frequency with minimal interference.
