Data Recovery

Data is information or statistics, numbers or records that are important and are worth being preserved for future use. Data can be stored in various forms and in different sources depending on the type of data, its importance and volume.

These days, data is preferred to be stored in computers and memory storage devices like hard disks, compact discs (CDs), inbuilt memories in computers like Read Only Memory (ROM), Random Access Memory (RAM) or in magnetic tapes. The advantages of storing data in these places are that it is in a uniform manner and it is easily accessible and legible. There are various benefits in storing data in this manner, but certain measures of care are to be taken to safeguard the data that is stored in these specialized memories.

Whenever these memory gadgets are subjected to damage because of extensive heat or any natural calamities, physical tension, accidental damage by computer users, viral infections, accidental reformats or deletions, broken or damaged hard disk drives, the data stored in these systems get corrupted or damaged. Data recovery deals with the restoration of such damaged or lost files in the systems.

Data recovery can be done in two ways depending on the type of damage done to the system or file. The first method of data recovery is physical data recovery wherein the damage is due to external dirt or grim that gets deposited on the memory storage devices.

Another type of data recovery is logical data recovery, where the data is lost due to accidental reformatting of the existing files, accidental deletions or viral infections. Data recovery starts by implementing special software to check and remove any virus present in the affected system. Then data recovery software is used to screen the system and a sector by sector analysis is done. Wherever damage is detected, the data recovery software repairs the damage.

The various types of data recovery are disk data recovery where data is retrieved from damaged disks, hard drive data recovery wherein data is recovered from hard drives and tape data recovery that repairs damaged tapes. Data recovery can be done on different platforms like UNIX based systems like Solaris, Linux and file systems with windows. Data recovery helps overcome the fear of losing important information and data.

Business Intelligence Data Mining

Data mining can be technically defined as the automated extraction of hidden information from large databases for predictive analysis. In other words, it is the retrieval of useful information from large masses of data, which is also presented in an analyzed form for specific decision-making.

Data mining requires the use of mathematical algorithms and statistical techniques integrated with software tools. The final product is an easy-to-use software package that can be used even by non-mathematicians to effectively analyze the data they have. Data Mining is used in several applications like market research, consumer behavior, direct marketing, bioinformatics, genetics, text analysis, fraud detection, web site personalization, e-commerce, healthcare, customer relationship management, financial services and telecommunications.

Business intelligence data mining is used in market research, industry research, and for competitor analysis. It has applications in major industries like direct marketing, e-commerce, customer relationship management, healthcare, the oil and gas industry, scientific tests, genetics, telecommunications, financial services and utilities. BI uses various technologies like data mining, scorecarding, data warehouses, text mining, decision support systems, executive information systems, management information systems and geographic information systems for analyzing useful information for business decision making.

Business intelligence is a broader arena of decision-making that uses data mining as one of the tools. In fact, the use of data mining in BI makes the data more relevant in application. There are several kinds of data mining: text mining, web mining, social networks data mining, relational databases, pictorial data mining, audio data mining and video data mining, that are all used in business intelligence applications.

Some data mining tools used in BI are: decision trees, information gain, probability, probability density functions, Gaussians, maximum likelihood estimation, Gaussian Baves classification, cross-validation, neural networks, instance-based learning /case-based/ memory-based/non-parametric, regression algorithms, Bayesian networks, Gaussian mixture models, K-means and hierarchical clustering, Markov models and so on.

Business Expense Reports

Business Expense Reports are the records of all the expenses incurred by the employees, top level to supervisory level, during their business visits on behalf of the companies. For this purpose, the business organizations should have standard business expense report forms. Nowadays, most of the companies are implementing web-based expense report software like Expense Management Automation (EMA), which automates and quickens the submission, approval and reimbursement processes of the business expense reports.

According to Aberdeen’s research group, EMA helps the business organization in reducing the time required for filling up the expense report by 60%, in decreasing the cost of processing a business expense report by 80% and also in cutting the time required for meeting the claim by 90%. This particular software is supplied by a large number of companies, namely Acceleron, PeopleSoft, SAP, Gelco, Oracle, etc. This software integrates all the processes starting from completing the expense report to receipt processing.

It is true that the employees’ expenses during their business visits occupy a vital role in the total expenses of the business organizations after salaries. According to one survey conducted by a popular Boston-based research organization, it is reported that for every five dollars a company spends, one dollar will be towards employee travel expenses. So companies are taking a very hard look at these expenses. It is observed that most of the business executives are relying on the travel agencies and credit card companies like American Express and Visa International for travel arrangements like ticket booking, hotel accommodations, etc. But, instead, if they make all these arrangements online, there would be a significant cost savings. As per one research survey, such online activity can cut costs by 20 percent. Therefore, online systems are a cost-effective means of controlling travel-related expenses. For trimming the costs, some companies committing to employee-friendly travel policies with their favorite carriers, who will offer discount rates.

Broadband Internet

Broadband Internet is an advanced and revolutionary technology that has allowed high-speed and efficient Internet service and connectivity. It is distinct in its operation from any other from of communication channel or network. In the ordinary base or narrow-band connection used in normal telephone lines, the fastest speed for transmission of data, even after using a speed modem, is only 56 kbps. Advanced technology in broadband allows a substantial amount of information to be carried and processed simultaneously at a faster rate. This leads to greater connectivity or web access, and higher download speeds. The Federal Communication Commission describes broadband as an Internet connection with a download speed higher than 200 kbps. The actual speed, however, can be as high as 256kbps, if not more.

A broadband Internet connection enables multiple data or information, video, image, audio or data signals of different frequencies to be transmitted simultaneously, at very high speed, to different network carriers. Broadband is like a tunnel with high capacity. There are different sub-tunnels, with each tunnel transmitting different information at a high speed. Each sub-tunnel is protected from any interference of disruption from the others. Distance doesn’t affect connectivity, especially in wi-fi and satellite broadband connections.

The broadband Internet connection operates by using several different technologies or media. A traditional dial-up connection uses a telephone line and a modem. The information is converted into analog form, leading to less connectivity and speed. The telephone line cannot be used for normal phone calls when Internet is in use. A broadband Internet connection also uses an existing telephone line for a DSL connection. The information is transmitted using the digital broadband technology; hence, speed and connectivity is higher. The other types include cable broadband connections using existing cable lines, T1 and T3 satellite and wi-fi (wireless fidelity) connections. In case of cable or DSL connection, TV or telephone functioning remains unaffected.

Broadband Internet Access

Broadband Internet access has redefined the boundaries of web networking. The time required to access the Internet, as well as to download information of different frequencies from the web, has been dramatically reduced. Web information is conveniently and easily accessible without being affected by long distances. Broadband Internet access is especially suitable for those who require instant and prolonged or constant (24/7) access to the Internet. Although it is a little more expensive then the traditional narrow-band Internet connection or dial-up network, the benefits fully compensate for the little price difference. A broadband connection ensures that the functioning of the cable and television line is not affected during connection, and vice-versa.

There are different types of broadband Internet access. The most efficient and reliable way it is accessed by home customers is through a cable broadband connection. This runs on an existing cable or coaxial connection. Another convenient way to access this technology is a DSL connection that uses an existing telephone line. Both these technologies are widely used by urbanites already having a telephone or cable connection. Most subscribers provide a 24-hour service for a flat monthly price. The T1 and T3 type of broadband connection is generally accessed by large business houses and universities. These oldest forms of broadband connections are the most efficient, but are also the most expensive. Access to broadband Internet connections is dependent on one’s geographical location. Although distance doesn’t usually affect speed and efficiency, the availability of infrastructure is a problem in remote rural areas and while one is traveling. Many of these difficulties have been addressed by the advent of satellite broadband Internet connections using land stations to receive land station transmissions. Wi-fi, or wireless broadband connection, is a revolutionary technology that promises to remove the restraints of distance, time and location. It allows one to access the net even in mid-air. Technology and special programs have made broadband Internet access viable for senior citizens or people with special needs (deaf or blind).

Best Passwords

No sane person would ever like someone else reading her email. Or for that matter some other person using her password and breaking into a financial institution. You should, therefore, choose a strong, secure password in such a manner that would be a hard nut to crack for others and easy for you to remember. The more random and mixed-up you make it, the harder it is for others to crack. Mind you, if your password is compromised, the password crackers will even take over your identity.

A password, if too short, is vulnerable to attack if an attacker gets hold of the cryptographic hash of the password. Present-day computers are fast enough to try all alphabetic passwords shorter than seven characters. We can call a password weak if it is short or is a default, or which can be rapidly guessed by searching a subset of all possible passwords such as words in the dictionary, proper names, words based on the user name or common variations on these themes.

On the other hand, a strong password would be sufficiently long, random, or which can be produced only by the user who chose it, so that ‘guessing’ for it will require too long a time.

For maximum security, the user should follow some simple guidelines:

1) Passwords should preferably be at least 8 characters long and not more than 14.

2) Passwords should contain a mix of numbers, letters, and special characters (%&3ac_ht4@m7).

3) Passwords should not contain a dictionary word from any dictionary, be it French, Spanish, medical, etc.

4) Each password should be different from the user’s User-ID and any permutation of that User-ID.

5) New passwords and old passwords should differ by at least 3 characters.

6) Avoid picking names or nicknames of people, pets, or places, or personal information that can be easily found out, such as your birthday, address etc.

7) It’s wise to stay away from common keyboard sequences, such as dfgh678 or abc345 .
8) Never form a password by appending a digit to a word. That can be easily guessed.

9) Avoid writing your password down or storing it on your computer.

10) Never share your password with anyone else.

Best Maintenance Software

In today’s technology savvy world, many companies are turning to the IT industry to assist them in managing their business endeavors. Many companies use maintenance software to help plan, procure, deliver, manage and improve reliability and utilization of their assets and physical infrastructures. It also helps them to support their core business, reduce risk, and maximize shareholder value. Maintenance software is an essential component of most businesses in industries as varied as software, fashion, hardware, food and electronics. One of the essential prerequisites is of course, that the maintenance software must be easy to install, use, maintain and update.

If the maintenance software is PC based, then it must be able to make full use of the extensive capabilities of Microsoft windows. Web based maintenance software are very useful and are more in trend nowadays. Most such software are open source and their programming codes can be revised or changed to suit the individual needs of a user.

The best maintenance software meets the distinct requirements of a client. Work management, physical assets management and resource management are the three basic components of most maintenance software that help improve a company’s analysis, production, sales and maintenance of products and services. They also help keep track of HR, finances, inventory and other sectors of a company. Different types of maintenance software like fleet maintenance software, asset maintenance software and production maintenance software are available which can be utilized to maintain the various sections or branches within a company.

Best Maintenance Management Software

The process of managing any business, whether it supplies products or services, is not an easy task. Most industries have to go through several processes such as procuring raw materials, processing, production, sales and maintenance. All these processes have to be in coordination with one another in order to cement a company’s success. The task is further complicated by factors such as globalization and the need for large-scale production. Inability to deal with these problems may lead to break down of physical assets and malfunctioning of various processes, which ultimately lead to products and service below par. This initiates the need of a tool such as maintenance management software (MMS), which helps various processes and branches of a company to be in sync with one another. The best maintenance management software is the kind that helps with coordinating the day-to-day operations of various departments in a company and plans the long-term utilization of assets with the minimal usage of resources.

Any good maintenance management software will satisfy the specific requirements of a client. All maintenance management software have three basic components namely, work management, physical assets management and resource management. These components help users improve their analysis, production, sales and maintenance of their products and services. They are also very useful in keeping track of the various functions such as human resources, finances, inventory and sales. A few of the maintenance management software available in the market today are fleet maintenance management software, asset maintenance management software and production maintenance management software. They are used to maintain the various departments within a company. User must be careful to buy only software that truly meets their needs.

Good maintenance management software is easy to install, use, maintain and update. PC based maintenance management software makes full use of the extensive capabilities of Microsoft Windows. Web-based maintenance management software is also very useful and is more popular these days than in the past.

Some companies that develop maintenance management software offer free download of the trial versions from their websites. Users can try out these test versions to ensure that the software is compatible with their business needs and then go on to buy the full product from the company.

Becoming an EKG Technician

EKG technicians assist physicians in diagnosing and treating heart disease, coronary artery disease and a multitude of other heart ailments. These technicians generally specialize in one of three cardiovascular fields: invasive cardiology, echocardiography, and vascular technology. EKG technicians are often referred to as electrocardiograph technicians.

While some, although few, electrocardiograph technicians are trained on the job, most health care facilities require specific training for this position. Most technicians complete a 2- or 4-year program in order to become an EKG specialist. Many people in this field attend a community college in which the first year of studies is general education followed by another year of intense training with internships at local hospitals. Some graduates, depending on the school attended, are able to receive professional certification in this field.

The EKG technician is a highly trained and skilled professional. He or she is trained in the points in which to place the electrodes. During the electrocardiogram, the technician will likely remain in the examination room to monitor the EKD readings. When the exam is complete, the technician can use his or her training to read and interpret the graphed results. Some technicians prefer to wait and allow the physician to relay results to the patient, while others will give the patient an immediate interpretation; this is especially true if no abnormalities are suspected.

Please Note: While the medical field is probably the fastest growing and most understaffed field in the United States and the greatest need in the U.S. medical field are nurses and nurse practitioners, this is not true for EKG technicians. EKG technicians are considered a specialty within the cardiovascular field. According to the U.S. Department of Labor, among all of the specialties in the medical field, the need for EKG technicians is the most slowly growing. With less demand in the field and more student choosing to this field of study, the need for qualified EKG technicians has not grown significantly.

Bar Codes

Norman Woodland, a 27-year-old graduate student at Drexel Institute of Technology in Philadelphia developed the first code system that automatically read product information during checkout. Woodland and his friend Silver were awarded a patent for their application titled Classifying Apparatus and Method on October 7, 1952. Many experts are of the view that the Woodland and Silver bar code was the basis of what would soon become a global phenomenon.

In the beginning, barcodes were developed to store data in the spacing of printed parallel lines. The idea was to help grocery stores speed up the checkout process and keep better track of the inventory. However, the system soon picked up and became a success story.

Barcodes form the basis of identification in almost all types of businesses in the modern world. Barcodes are variously called as Universal Product Codes or UPCs. These are machine-readable codes and come in strips, generally comprising of a series of short black lines of varied thickness. These codes are read by optical scanners called barcode readers or scanned from an image by special software. A laser reader or scanner can translate the barcodes into the corresponding alpha-numeric digits, which are used to uniquely identify a piece of property. Barcodes are used world over to implement Auto ID Data Capture (AIDC) systems that improve the speed and accuracy of computer data entry.

At present, we have codes in several patterns of dots, concentric circles and hidden in images. Barcodes are provided by a body called Uniform Code Council (UCC). A manufacturer has to apply to the UCC for permission to enter the UPC system. An annual fee is charged for the service. In return, the UCC issues the manufacturer a six-digit manufacturer identification number. The manufacturer identification number is part of a standard 12-digit bar code.

Bar coding standards have brought about great precision, technical refinement and uniformity in the way business is conducted in the world. Throughout the world, most of the data entry is done much more quickly. All data is collected in real time. Bar codes have also led to the elimination of manual data entry and retrieval system. The coding has completely streamlined products, making the most effective use of human and physical resources.
