Agony of the data loss is the one which can affect not only the individuals but the big corporates also. Losing the precious data is proving as the wakening threat for all of them and thus makes them to undergo this ordeal.

Formatting the hard drive without any intention or to removing the nasty computer viruses may be revered as one of the archetype of data loss. Apart from this file or folder deletion and dropped hard drive are some other which are constituted in the common term human error. The data recovery is the need which runs like a common thread among all of them who have faced this or similar conditions.

To the part of your interest, this nightmare for the users is then converted into plentiful for the business opportunities of data recovery players. The data recovery from the hard disk and other storage media is a fragmented market today and choosing the apt one in need is really a tough job to do.

The data recovery job is not limited to private sectors but the government is also arming itself to get back their lost sensitive data. Prime Minister's office, ISRO, Army headquarters, various ministries and public sector undertakings (PSU), have deployed tools to this effect.

Also the agencies like security and law enforcement agencies are using data recovery services to solve their cases. These are the cases where criminals play their part by destroying the related information from electronic data storage devices by deleting or destroying it.

At this point of discussion how can we forget of naming the corporate biggies for which the data loss can be comparatively more fatal? This is with respect of the reason that the revenue streams and survival of these companies depend almost totally on data.

Now at this point of time businesses and all the concerned ones to data have come to realize the seriousness of data and have thus started to do their part. They have began building the data loss prevention factor as the most relevant in their annual maintenance contracts or service level agreements with IT service providers.

While a spin-off of this growing menace has resulted in the emergence of a fast-growing data recovery industry. But the matter is which one to choose out of this flooded market. Well you will get this answer after a wide analysis and research made on the internet or manually. Going for the data recovery software or data recovery services is something different which depends on the nature of the problem but the best deal would be to choose the data recovery company which offers you both with bets of the flexible options.

Stellar Information Systems Ltd. is the data recovery company which is considered to be the most reliable and the renowned data recovery company so far. The data recovery solutions and services of Stellar mark a large impact to the satisfaction level of the customers.

The data recovery services are provided in the Class 100 Clean Rooms with best of the data recovery tools under the sight of qualified and skilled data recovery professionals. They make a wide research of the damaged hard drive to know the actual reason of the crash and then go as per the case may be.

The data recovery software provided by Stellar are also the best and most reliable, available for the operating systems like Windows, Macintosh, Linux, UNIX and Novell. The advanced scanning procedure of the storage media through the use of the best algorithms makes the data recovery safe and complete.

Top Ten Concepts For Linux Beginners - Number 9, Certification

Subscribe in a Reader

DON'T FORGET TO COMMENT ON THIS ARTICLE

by Levi Reiss

There are currently four programs that enable people to become certified as Linux Systems Administrators. These programs are offered by the Computing Technology Industry Association, the Linux Professional Institute, the Novell Corporation, and Red Hat, Inc. The first two are professional industry associations whose certification programs do not depend on any specific Linux distribution. Novell and Red Hat Linux certifications are closely associated with their popular Linux distributions. Should you wish to prepare for either of these two certifications you will definitely need access to their Linux version.

What's involved in obtaining a Linux Certification? You must pass one or more extensive tests that demonstrate your prowess in dealing with the typical and some atypical problems faced by Linux systems administrators. We'll take a closer look at the CompTIA Linux+™ Certification, the one often recommended as the first certification for people new to Linux. This certification does not apply to any specific Linux version. The test is designed to validate the knowledge of individuals with a minimum of six to twelve months of practical Linux experience. According to the Computing Technology Industry Association, professionals achieving the CompTIA Linux+ certification can explain fundamental management of Linux systems from the command line, demonstrate knowledge of user administration, understand file permissions, software configurations, and management of Linux-based clients, server systems, and security. Many of these functions are available on Damn Small Linux.

The Linux+ certification is a basic, entry-level certification for Linux system administrators. It is intended for people with six-months experience installing, operating and maintaining Linux operating systems. To achieve Linux+ certification, candidates must pass the 98 question Linux+ exam which covers seven areas: Planning and Implementation; Installation; Configuration; Administration; System Maintenance; Troubleshooting; and Identify, Install and Maintain System Hardware. This multiple-choice exam costs about $232 and is a good starting point for those who want to continue with other Linux certifications including those from Novell and Red Hat.

Why would anybody want to start preparing Linux certification on a limited version of Linux? The answer is simple – certification is not to be taken lightly. Don't make a major financial and time investment unless you know that you really want to be certified and that you possess the required skill set. It's not hard to find schools that promise you success in Linux certification and in any of their course offerings. But Linux certification may not be for you. Don't make a major certification investment only to find that it wasn't what you had in mind. Work your way through my tutorials including the suggestions for going further. Get your hands on a variety of Linux books. I would start with books designed for learning Linux and for running Linux systems before working with Linux certification books.

Don't be satisfied with running computer exercises in your mind, and nodding your head at the appropriate times. To succeed you must do the exercises on a computer running Linux. Since installation is a component of all Linux Certification exams don't stint on installing several versions of Linux on your computer. An external USB hard drive is not very expensive. Try to make friends with someone who knows better than you how to do things. Ask a lot of questions. And good luck!

And while you're working on your certifications take a look at some of Damn Small Linux's other advantages in our final article in this series.

Levi Reiss authored or co-authored ten computer and Internet books. He teaches Linux and other computer subjects at an Ontario French-language college. Visit his new site www.linux4windows.com, to learn how to download and run free Damn Small Linux on your Windows computer.

The Current Status of FTTH in the US and the Rest of the World

by Colin Yao

Understanding FTTH (Fiber To The Home)

FTTH is an all-fiber connection to the home which provides a minimum of 155Mbps bandwidth on both up stream and down stream directions. Basically, it is composed of a fiber from the service node to the optical splitter, the optical splitter which separates to (fan out) terminate on single home ONU.

So similar to FTTC (Fiber To The Curb), FTTH is a point-to-point architecture with a dedicated connection from the home to the network. This fiber link provides secure transmissions by virtue of the fact the it is much harder to tap a fiber than a copper cable.

FTTH is much better suited for broadband service applications than DSL and other intermediate technologies. It is our broadband future.

Cost Savings of FTTH

FTTH provides a robust outside plant which requires extremely low maintenance over the lifetime of the system. Fiber based networks require considerably less maintenance than traditional copper networks.

FTTH in the US

Currently in the US, FTTH is not yet a real alternative challenge to interactive digital services distributed over cable, DSL, satellite and other media. Why? The simple reason is the cost. The cost for roll out a widespread FTTH infrastructure is exorbitant and therefore currently it is only feasible in urban and business areas.

FTTH offers up to 20 times more bandwidth than ADSL which is tremendous to most Americans. And once the fibers are in the ground, the capacity can be upgrade to even more by simply upgrading or adding new equipment on the end. In the future, FTTH will not only be offered to larger business customers but also for residential customers, SoHos and SMEs.

However, most of the largest telcos are still limiting their FTTH deployment to small-scale trials. But many smaller carriers and newcomers are pushing ahead with actual product offerings and are creating a significant base of fiber users. Bellsouth is playing a very active role. Another active player is Verizon with its FiOS offering.

Fiber-to-the-home connections in the U.S. have more than doubled from a year ago to surpass the 2 million mark, according to data released today from Render Vanderslice and Associates.

Verizon Communications accounts for about two thirds of the country's FTTH subscribers and more than two thirds of the homes passed by fiber.

Other players including AboveNet and Paxio. AboveNet, PAXIO team on FTTH network in San Francisco Bay area.

FTTH in Europe

In Europe, FTTH is just at the beginning of its life cycle. In Germany, BerliKomm (based in Berlin) is preparing to offer FTTH. And in Sweden, Bredbandsbolaget (the leading FTTH player) is already offering FTTH services. In Austria, Wienstrom is also offering FTTH service under the name of "i-blizz".

FTTH in Asia

Hong Kong, South Korea and Japan are the world leaders in the percentage of homes that receive broadband communications services over direct fiber optic connections, according to a new global ranking of fiber-to-the-home (FTTH) market penetration.

According to this first ever official ranking of FTTH deployments in the world's economies, 21.2 percent of homes in Hong Kong are wired with FTTH, followed by South Korea at 19.6 percent and Japan at 16.3 percent. Scandinavian countries occupy the next three positions, with Sweden having 7.2 percent of its households connected to FTTH, Denmark at 2.9 percent and Norway at 2.5 percent.
Taiwan, Italy, People's Republic of China, The Netherlands and the United States round out the top 11 economies, with FTTH penetration rates of between 1.4 and 1 percent of households. Only economies with penetration of 1 percent or more were included in the ranking.
The three regional FTTH Councils joined together to create this first official global FTTH ranking in order to provide the telecommunications industry, governments and regulators with a unique snapshot of international fiber access penetration. Going forward, the councils will update and re-issue the rankings on an annual basis, as well as work jointly to further refine the research methods in order to provide more in-depth information.

Enter To Win

by Sheezaym

Have you ever wondered if people really do win at sweepstakes and contests? Have you tried to enter as much as you can, but still have come up empty handed? Well, don't give up just yet!

Winning at sweepstakes is very common among sweep enthusiasts, if you have the right mindset and strategy. Yes, you do need a plan! The first thing is getting used to the terminology used, and some basic rules. There is a big difference between a sweepstakes and a contest. A sweepstakes is when a company holds a prize drawing with absolutely no strings attached. They do not require commitments or purchases. They are merely introducing a new product, company or maybe a new media, (such as movies & music). You may run into a website that offers various non related prizes every week, or month. It may not be their own products, but they would like you to see what they have to offer. Their sole purpose is for you to get to know them better.

A contest is a little different. They too, are offering a prize so that you will come and visit them, and see what they are all about. They may want to spice some things up and get you a little more involved with their company before you enter to win. They want to attract people to their contest that has a genuine interest in their product. They may ask you to send them a recipe or a photo. They may have a trivia game for you to play. Some contests have you find different things on their website. All are meant for fun, and for them to introduce themselves to you.

Sometimes though, you may run into a contest that has you pay to enter. I strongly urge you not to pay to enter a contest. To me, it is a large red flag when I see contests that you need to pay to win! Please, don't waste your money! Raffles for charity causes are my only exception. I believe that if we have a charity that we consider to be important, than by all means please support them! If you win a prize of some sort, than it can be a little sunshine to your day!

Data Loss Effects on Different Types of Companies

by Andrew Watson

No one can contradict the fact that how the data loss can severely impact the companies. But this is not necessary that this impact is same for all of them. Let us say any R&D company has suffered hard drive crash then due to having some confidential data related to the new inventions, this is hard for it to trust on any of the data recovery service provider company.

So this becomes a hard and fast rule for that company that to choose the one which is reliable and has been known for the same from decades. This will let the R&D companies to be sure that the data will remain confidential and the success of the data recovery operations is guaranteed.

Some R&D projects take several years to get completed. So loosing any of the information about the projects is not at the money level but this also the time loss that the developers have spent.

The banks and financial institutions are running their business based on the millions of transactions each day. Now let us suppose that a person wants to invest $ 2000 in the stock market but due to the present data loss problems in the stock brokerage company, he/she can't do so. If the company deals with approximately 100 transactions each day then the total loss would be $ 20000 per day until the data recovery is not done. Thus the longer it takes for data recovery, the larger it will loose.

A customer only puts his/her money in your financial institution if he or she trusts your company and if that gets lost then this costs at price of the market reputation of the institution. Such types of data loss incidents will make the customer to doubt your trustworthiness and he or she is bound to take his or her business elsewhere.

For the film and advertisement companies, lot of time, money and efforts are required. There is a use of lot of external technical expertise and resources that cannot be replicated easily. If some film or advertisement copy is lost then that would mean losing all the financial resources that went into making that copy. As lot of money has been spent in producing the movie but a silly data loss incident can convert this expenditure into large financial losses and no benefits.

So as proved from the above examples, the data loss can affect in several of the ways to the company based on the works that the company performs and the type of information it possess. So the relevance of data recovery runs the uniform kinds of issues for them. However the way outs for uncovering the data loss is unique for all i.e. data recovery software for logical data loss and data recovery services for the physical data loss.

Seeking the confidential matters and safety aspects of the data, the reliability of the data recovery software and guarantee of the data recovery company that they will go for keeping the data confidential is the primary facet to be seen. So better choose according to your needs.

Stellar Information System Ltd. is a data recovery company which fulfills all your data recovery needs. The data recovery software are available for operating systems like Windows, Macintosh, Linux, UNIX and Novell. They perform a systematic scan of your hard drive and fetch your data from it. These data recovery software do not alter the data even a bit and retrieve them intact.

Data recovery service by Stellar is provided in the Class 100 Clean Room where apt surroundings are given to the failed hard drive. Stellar assures you that your data will remain just under your limits and will not leak at all after data recovery by its experts.

The data recovery experts are well qualified and experienced and carry out the best procedures for the data recovery.

Cisco CCNA, CCNP, and Network+ Exam Practice Questions: ARP, Layer 3 Switches, WPA, and More!

Subscribe in a Reader

DON'T FORGET TO COMMENT ON THIS ARTICLE

by Chris Bryant, CCIE #12933

Test your knowledge of vital Cisco and CompTIA certification exam topics with these free questions!

Network+ / CCENT / CCNA Question:

What protocol allows a host to determine the MAC address of another host that is on a different side of the router?

Answer: Proxy ARP.



CCENT Certification:

Briefly describe how a Cisco switch builds its MAC address table.

Answer: The switch examines the source MAC address of incoming frames, then checks its MAC address table to see if an entry exists for that address. If not, an entry is made that maps that MAC address to the port that received the frame.


CCNA Certification:

Convert the binary string 10101010 into a hex value.

Answer: In decimal, that string equals 170; that's AA (or aa, case does not matter).


CCNP Certification / BSCI Exam:

In the BGP best-path selection process, what is the first attribute a Cisco router examines?

Answer: The Cisco-proprietary attribute weight is the first attribute considered.



CCNP Certification / BCMSN Exam:

On a Cisco L3 switch, what command converts a routing port to a switching port?

Answer: The command is switchport. To change a port from switching to routing, run no switchport.


CCNP Certification / ISCW Exam:

Basically, what is a "demilitarized zone"?

Answer: A DMZ is the area between a company's private network ("inside network") and the outside world. Packets going from the inside network to the DMZ and from the DMZ to external networks are generally examined by security devices.


CCNP Certification / ONT Exam:

Name three major differences between WEP and WPA.

Answer: Wired Equivalent Privacy (WEP) offers static keys, an easily hacked authentication setup, and is not considered a scalable solution. Sounds promising, right? That's why WPA is a much more attractive solution. WPA uses dynamic keys, isn't easily hacked, and is highly scalable.
