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. Buyers are advised to carefully evaluate the software in order to buy one that satisfies their specific requirements.

Several companies that sell maintenance software offer free downloads of maintenance software on the net. Users can try out these small versions to check out if the software is compatible with their business needs and then go on to buy the full product version from the 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. Most maintenance management software is open source and the programming codes can be revised or changed to suit the individual needs of a user.

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.

Bar Code Software

Barcode software comes in various styles. It is used to create professional barcode labels. It can be uploaded on a computer like any other software program and possesses a myriad of features. The barcode software can print barcodes on any installed printer with graphics capability. Such software often consists of a menu that displays different options in a user-friendly language. Modern software is very easy to use, giving the user the option to decide a label’s appearance, including the type and size of text, bar codes and graphics. Dialogs, another important feature of many barcode software programs, offer many options to design labels and print barcodes.

Many barcode software programs available in the market offer tool tips. These are basically quick hints that help in modifying and printing multiple label designs. Similarly, high precision on-screen design mode provides an accurate real-time view of a label. Print preview mode displays exactly how the labels look before they can be printed. Perhaps the best part of barcode software is that it usually comes with an array of font capabilities. It solely depends on the imagination of the user to put these fonts to the most flexible use with maximum speed. Several printer drivers have the option to support font downloading.

Software consists of a toolbox that provides access to an extensive series of barcode components. The rich text option allows for multiple typefaces and styles. Graphics can be easily imported or exported in barcode software. That makes logos, pictures and company images easy to adapt. Barcode software is programmed to be latched onto all kinds of laser, ink-jet and dot-matrix printers. This software also provides access to countless high-quality symbols. They also allow serialization sequences. We can choose the sequence from a variety of character sets. Modern software is armed with the option of customizing a user’s own features.

Bar Code Scanners

Barcode Scanners are hand-held or stationary devices used to read information contained in a barcode. These devices are connected to a computer through any type of port. Scanners cannot do calculations; they only capture the barcode into letters or numbers. Information, once fed into a computer is processed by the computer’s software. A barcode scanner consists of a code reader and decoder. The reader throws light on a barcode and measures the amount of light that is reflected back by the barcode. This light energy is converted into electrical energy by a scanner. The electrical energy in turn is changed into data in the computer.

Barcode scanners are available in many different varieties. They can be hand held and hands free, wearable, rugged, scan engines, laser or digital. Pen-wand scanners are perhaps the simplest types of such devices. They have to be kept in direct contact with the barcode and held at a precise angle. A pen-wand scanner is moved over the bar to read it. General purpose scanners are generally used at checkout counters and hospitals and are also used to process identification documents. Certain other kinds of scanners, like rugged scanners, are generally used in harsh or extreme conditions.

Another major distinction of barcode scanners is that of an image scanner and a laser scanner. A camera reader is embedded in an image scanner. The camera captures the barcode images, which are then processed by sophisticated image techniques to decode the barcode. An image scanner can read a barcode from four to ten inches away. Laser scanners use lenses to read the codes. Laser scanners enjoy the advantage of reading the bar even from a distance of 24 inches. Moreover a laser scanner can be positioned at any angle to read a barcode. With the advancement of technology, modern laser scanners can read the barcodes with ease from a distance of 30 feet.

Bar Code Printers

Barcode Printers come in various types, including general-purpose laser and inkjet printers. Then there are printers that support multiple symbologies. They are called Thermal bar code label printers. General-purpose laser and inkjet printers cannot directly print barcodes. That is because these basic printers do not support bar code symbologies and are therefore upgraded to do so. They need to be programmed to support bar coding, which may entail addition of more features and fonts.

Barcode printers employ two major printing methods, namely Direct Thermal and Thermal Transfer. Both methods basically involve the same technique to print bar codes with difference in the use of ribbon. They make use of a print-head that applies heat to a surface that is pre-marked. Heated ribbon is used to produce long-lasting images in Thermal Transfer printing, while Direct Thermal does not use ribbon and instead prints the image directly on the label. In Thermal Transfer printing, a large number of materials may be used. This generally helps in creating durable images over a long period of time. Direct Thermal, on the other hand, helps in making put-away labels, receipts and other such small variety.

Ideally, barcode printers can print on labels that are specifically designed for the purpose. However, the printers are also capable of printing on fabrics like polyester. We have printers etching away prints on headbands and even synthetic materials. Quite contrary to popular perception, barcodes are not only black. Barcode printers can print in various colors, but black is generally preferred because a light color may end up with insufficient contrast between the bars resulting in unreadable barcodes.

Nowadays, several security features are available to ensure that there is no counterfeit coding by the printers. The latest thermal printers are capable of printing smart labels that contain radio frequency identification chips within the label media. These smart features go a long way in plugging any loopholes in barcode printing and provide a guarantee of authentication.
