How To Select The Best Credit Repair Software

Credit repair software tools are available to assist both credit repair agencies and/or individual consumers with credit repair. Ideally, such repair software is user-friendly and allows the user to point and click to a series of questions, and subsequent options, to engage in the process of credit repair by challenging credit reports from the major credit bureaus.

There are many software companies to choose from. Some claim to be the “best” while others claim to have the “absolute best credit repair software on the planet.” They all provide a unique service with even more unique and distinct features. The issue that you need to consider most when selecting credit repair software is which feature set will benefit you the most. So let’s take a look at steps that will help you select the proper software package for you.

1. Try to find a product with good technical support. A proper credit repair software program behaves like other expert software. This means 24/7 technical assistance, recurring software updates, sufficient help/manual documentation, etc.

2. Your credit repair software must adhere to your personal needs. A lot of these products have numerous add-ons, bonuses and other things which you would be paying for, but may not need. For example, some vendors cater to credit professionals, so they have functionalities on client management, etc, which you don’t need as a home user. On the other hand, you might need financial tips or the automatic reminder system.

3. Keep in mind, that you may have to write letters and that you are a unique customer with a unique address, account number, social security number, and story behind your dispute, which will have to be inside the letter. This single activity will take you many hours to complete. Try to find a software that already has pre-loaded dispute letters. Then once the software has automatically extracted those disputes from the above mentioned credit report providers, this software will in turn suggest the appropriate dispute letter automatically within just a few seconds. Just imagine the hours, and amount of money you can save by just this feature alone. Most people have to hire or outsource this kind of work because their software does not do it automatically. So not only will you save time but you will also save money by not having to outsource the work.

4. Rank available packages through analyzing pros/cons/cost. Once you have a short list of possible software packages, try to rank them by analyzing the pros and cons of each, as well as comparing the cost to your budget.

5. See if there is a trial period for the software that you select. Now that you have selected which package you feel would be the best fit for you, make sure that there is a money back guarantee so that you can return it if you are not satisfied with the performance.

The more you work on your credit repair, the more that it will demand of your time. This is why it is extremely important to choose the best credit repair software available to help you automate the process as much as possible. Choosing the right software package for your needs can save you lots of time. Working with automated software can be compared to driving a car to a distant destination, versus walking there. One way will be significantly faster than the other. Repairing your credit will be much more difficult if you are not using an organized system.

Medical Coding History – From Paper to Medial Coding Software

If we define medical coding as the assignment of alphanumerical characters to diagnoses, diseases, and treatments, then medical coding has been traced back to the 1600s in England with the London Bills of Mortality. A more standardized system of coding was developed for classifying death at the tail end of the 19th century. In 1893, Jacque Bertillon, a statistician, created the Bertillon Classification of Causes of Death, a system which was eventually adopted by 26 countries at the beginning of the 20th century. Shortly after the Bertillon Classification system was implemented, people began discussing the possibility of expanding the system beyond mortality as a way of tracking diseases.

By the middle of the 20th century, the World Health Organization (WHO) adopted a goal of a single global classification system for disease and mortality, entitled the International Classification of Diseases, Injuries, and Causes of Death (ICD). This classification system is updated every 10 years. The latest revision, ICD-10, is scheduled for adoption in the United States in 2013.

What started out as a small set of medical codes has evolved into a complex system that was initially standardized by the American Medical Association back in 1966 with current procedure codes (CPT) codes that are updated annually.

In the late 1970s, the Healthcare Common Procedure Coding System (HCPCS) was developed based on CPT. HCPCS has three levels of codes: Level One is the original CPT system. Level Two codes are alphanumeric and include non-physician services such as ambulances and other transportation as well as patient devices such as prosthetic devices. Level Three codes were developed as local codes, and were discontinued in 2003 in order to keep all codes relevant worldwide.

Recently, medical coding systems have been expanded to include other medical specialties. For example, there are coding systems related to disabilities, the dental field, prescription drugs, and mental health.

As the coding systems have become more complex and diverse, the need for training of medical coders has grown exponentially. Private training schools and public colleges throughout the country have developed certification programs. In order to be awarded a certificate, students must obtain a two-year degree from an accredited medical coding school and pass an exam given by the AHIMA.

Over the past 20 years, many coding processes have shifted from a paper-based system to a computer-based system using medical coding software and medical billing software. Many companies sell complete medical software-based coding solutions and myriad of products for specific medical disciplines, such as products that are specifically tailored to skilled nursing facilities, physicians, hospitals, surgery, cardiology, and more.

As medical facilities and professionals begin preparing for the conversion to ICD-10 in 2013, the need for more sophisticated medical coding software solutions and qualified medical coders will continue to grow.

CPT is a registered trademark of the American Medical Association.

Corel DRAW – Best Desktop Publishing Software

Corel DRAW is a supreme supplier of graphics software, including the popular Corel DRAW program. Corel DRAW has tools that allow the user to both create and edit images. The type of desktop publishing tools that you use will depend on the type of project. For more information and assistance, use the Corel website.

Corel DRAW is the best Desktop publishing software that empowers users to create illustrations containing graphics, text and photographs. Corel has an extensive range of tools which enable the user to edit any shape or character with ease and precision, fit text to curves and create custom color separations. It is developed and marketed by Corporation of Ottawa. This tool can open files: Adobe PageMaker, Microsoft Publisher and Word, and other programs can print documents to Adobe PDF using the Writer printer driver, which such software can then open and edit every aspect of the original layout and design.

Several innovations to vector-based illustration originated with Corel: a node-edit tool that operates differently on different objects, fit text-to-path, stroke-before-fill, quick fill/stroke color selection palettes, perspective projections, mesh fills and complex gradient fills.

One of this software’s many strengths is the huge range of over 1,000 fonts that it comes with, provided in both TrueType and Postscript Type 1 format. Corel differentiates itself from its opponent in a number of ways: The first is its positioning as a graphics suite, rather than just a vector graphics program. A full range of editing tools allow the user to adjust contrast, color balance, change the format from RGB to CMYK, add special effects such as vignettes and special borders to bitmaps. Bitmaps can also be edited more extensively using Corel PhotoPaint, opening the bitmap directly from Corel and returning to the program after saving. It also allows a laser to cut out any drawings.

Expert believed it was the first of the Windows-based drawing programs and has built on this early start to become far-and-away the dominant drawing package on the PC. Its biggest strength – and its biggest potential limitation – is its all-encompassing approach. In the past this has led to accusations of unfocused bloating, but with version 7.0 Corel has addressed the criticisms with a far tighter and better rationalized program. Even so, there’s a huge range of functionality to cover.

Corel DRAW Download was originally developed for Microsoft Windows and currently runs on Windows XP, Windows Vista, and Windows 7. The current version, X5, was released on 23 February 2010.

How Car Mechanics Use Technology

Do you know why it’s important to find a good mechanic or a good repair shop to repair your car? The reason: it could save you hundreds of dollars in parts and labor! When we say a “good mechanic” or a “good repair shop”, we’re referring to mechanics who are equipped with the latest technology. You don’t want to entrust your car to a shop with outdated machinery and equipment because it will take longer to arrive at a diagnosis. And the longer a mechanic takes to make a diagnosis, the larger your bill for labor!

Remember that car mechanics charge by the hour.

Car repairs can cover any one or a combination of the following (note that this is not a complete repair list).

• Air conditioning checks

• Air bag checks

• Electrical wiring

• Cables

• Clutch service and repair

• Transmission repair

• Wheel Alignment

• Suspension

• Brakes

• Heating system

• Oil and lubrication

• Battery

• Power windows

Much of the troubleshooting that mechanics use to diagnose a problem is facilitated by car repair technology.

Ever noticed how some lights on your panel come on when something’s wrong? In most cases, an experienced mechanic will know immediately what the problem is, but there are instances where it will take sophisticated technology to lead to an accurate diagnosis.

Sophisticated technology comes in many forms and one popular one is troubleshooting software. Companies like Auto Tech have a software program that car owners can use to find out what is ailing their vehicle.

Most car owners who were cynical about software programs before should seriously consider purchasing a reliable car troubleshooting software program. For instance, some programs start out by asking you to input your car make and model number, the year of the car and what kinds of equipment it has. The software features a large database of information about all cars in the market and a car owner simply follows the steps when prompted. It employs what the industry calls a “tree diagnosis” where logical steps take you through the entire diagnosis process.

After you’ve keyed in your car’s profile, you use the drop down menu to choose the symptoms that your car is exhibiting. For instance, if you choose “squealing brakes”, the program mimics the squealing of brakes and if that’s the sound you hear, you confirm it and the program recommends a series of steps.

You may not really want to use a troubleshooting software, but imagine how much time and money you could save if you spoke to the mechanic intelligently, letting him know that you’re in the know.

Students who are studying towards certification buy certain tools of the trade. A couple of examples are Snap On and Mac Tools. These two are the most popular in the United States and Canada.

Mechanics now have a wide range of technology tools to help them understand car problems better: digital multimeters (electronic measuring), boroscopes (testing heat exchangers), fuel diagnostic testers (testing and balancing fuel injectors) and other such new technologies.

New car mechanic technologies help shorten the learning curve and speed up diagnosis so that the car owner isn’t saddled with too many labor hours.

Wide Area Network (WAN)

Types and Characteristics of WANs

What is a WAN?

There are two prevailing definitions of a Wide Area Network (WAN). The book definition of a WAN is a network that spans large geographical locations, typically to interconnect multiple Local Area Networks (LANs). The practical definition of a WAN is a network that traverses a public network or commercial carrier, using one of several WAN technologies

What are its Main Components?

The main components for a WAN are routers, switches and modems. These components are described below in the hardware section.

CPE – Devices on the subscriber contracts are called customer premises equipment (CPE).
The subscriber owns the CPE or leases the CPE from the service provider. A copper or fiber cable connects the CPE to the service provider's nearest exchange or central office. This cabling is often called the local loop, or "last-mile".

DTE / DCE – Devices that put data on the local loop are called data circuit-terminating equipment, or data communications equipment (DCE). The customer devices that pass the data to the DCE are called data terminal equipment (DTE). The DCE primarily provides an interface for the DTE into the communication link on the WAN cloud.

Hardware

In a WAN you will need various types of hardware components for it to function. The typical items of hardware that you will need in a WAN are:

Router – An electronic device that connects a local area network (LAN) to a wide area network (WAN) and handles the task of routing messages between the two networks. Operates at layer 3, and makes decisions using IP addresses.

Switch – A switch is a network device that selects a path or circuit for sending a unit of data to its next destination. Operates at layer 2, and uses MAC addresses to send data to correct destination.

Modem – Short for modulator / demodulator, a modem that enables a computer to communicate with other computers over telephone lines. Operates at layer 1, where signals are converted from digital to analogue and vice versa for transmission and receiving.

Wan Standards

WANs operate within the OSI model using layer 1 and layer 2 levels. The data link layer and the physical layer. The physical layer protocols describe how to provide electrical, mechanical and functional connections to the services provided by the ISP. The data link layer defines how data is encapsulated for transmission to remote sites.

Encapsulation

Encapsulation is the wrapping of data in a particular protocol header. Remember that WANs operate at the physical layer and the data link layer of the osi model and that higher layer protocols such as IP are encapsulated when sent across the WAN link. Serial interfaces support a wide range of WAN encapsulation types, which must be manually specified. These types include SDLC, PPP, Frame delay etc. Regardless of WAN encapsulation used it must be identical on both sides of the point to point link.

Packet and Circuit Switching

Circuit switching and packet switching are both used in high-capacity networks.
The majority of switched networks today get data across the network
Through packet switching.

Circuit-switching is more reliable than packet-switching. Circuit switching is old and expensive, packet switching is more modern.

General Routing Issues

What is a Routing Protocol?

A routing protocol is a protocol that specifies how routers communicate and exchange information on a network. Each router has prior knowledge of its immediate neighbors and knows the structure of the network topology. The routers know this because the routing protocol shares this information.

Protocol

RIP (Routing Information Protocol) was one of the most commonly used protocols on internal networks. Routers use RIP to dynamically adapt changes to the network connections and communicate information about which networks routers can reach and the distance between them. RIP is sometimes said to stand for Rest in Pieces in reference to the reputation that RIP has for breaking unexpectedly and rendering a network unable to function.

Routing Algorithms

Distance Vector

This type of routing protocol requires that each router simply inform its neighbors of its routing table. The distance vector protocol is also known as the bellman-ford algorithm.

Link State

This type of routing protocol requires that each router maintain a partial map of the network. The link state algorithm is also know as Dijkstra's algorithm.

IGRP

IGRP is a type of distance vector routing protocol invented by cisco used to exchange routing data in a autonomous system. Distance vector protocols measure distances and compare routes. Routers that use distance vector must send all or a portion of their routing table in a routing update message at regular intervals to each neighbor router.

Addressing and Routing

What does routing mean?

Routing is the process of deciding how to move packets from one network to another.
The directions also known as routes can be learned by a router using a routing protocol then the information is passed from router to router along the route of the destination.

IP Address's

Every machine connected to the internet is assigned an IP address. An example of an IP address would be 192.168.0.1. IP addresses are displayed in decimal format to make it easier for humans to understand but computers communicate in binary form. The four numbers that separate an IP address are called Octets. Each position consists of eight bits. When added to together you get 32 ​​bit address. The purpose of each octet in an IP address is to create classes of IP addresses that can be assigned within a network. There are three main classes that we deal with Class A, B and C. The octets of an IP address are split into two parts Network and Host. In a class A address the first octet is the network portion, this determinates which network the computer belongs to, the last octets of the address are the hosts that belong to the network.

Sub netting

Sub netting allows you to create multiple networks within a class A, B or C address. The subnet address is the address used by your LAN. In a Class C network address you would have a subnet mask of 255.255.255.0. A subnet mask identifies which portion is network and which is host. For example 192.168.6.15 the first octet three octets are the Network address and the last octet being the host (Workstation). It is important to subnet a network because gateways need to forward packets to other LANS. By giving each NIC on the gateway an IP address and a Subnet mask it allows the gateways to route packets from LAN to LAN. Once the packet arrives at its destination, the gateway then uses the bits of the subnet portion of the IP address to decide which LAN to send the packets.

Circuit Switched Leased Lines

A circuit switched network is one that establishes a dedicated circuit (or channel) between nodes and terminals before the users may communicate. Here are some terminologies associated with a Circuit switched network.

Frame relay is a telecommunication service designed for cost-efficient data transmission between local area networks (LANs)

Basic rate interference is a service used by small business for internet connectivity. An ISDN BRI provides two 64 Kbps digital channels to the user.
Primary rate interface (PRI) is a telecommunications standard for carrying voice and data transmissions between two locations
All data and voice channels are ISDN and operate at 64kbit / s

Packet Switching

Http://www.raduniversity.com/networks/2004/PacketSwitching/main.htm – _Toc80455261

Packet switching refers to protocols in which messages are broken up into small packets before they are sent. Each packet is then transmitted over the Internet. At the destination the packages are reassembled into the original message. Packet switching main difference from Circuit Switching is that that the communication lines are not dedicated to passing messages from the source to the destination. In Packet Switching, different messages can use the same network resources within the same time period.

Http://en.wikipedia.org/wiki/Asynchronous_Transfer_Mode

Asynchronous Transfer Mode (ATM) is a cell relay, packet switching network and protocolwhich encodes data into small fixed-sized cells.

ISDN is used to carry voice, data, video and images across a telephone network. ISDN stands for integrated services Digital Network. Isdn also provides users with a 128kbps bandwidth. This is done through frame relay. Frame relay complements and provides a service between ISDN, which offers bandwidth at 128 Kbps and Asynchronous Transfer Mode which operates in somewhat similar fashion to frame relay but at speeds from 155.520 Mbps or 622.080 Mbps. Frame relay is based on the older X.25 packet switching technology and is used to transmit analogue signals such as telephone conversations.

PSDN stands for packet switched data network and is a data communication network. Packet switched networks do not establish a physical communication signal like the public telephone circuit (circuit switched network) Packets are sent on a fixed length basis and assigned with a source and a destination address. The packages then explicitly on the routers to read the address and route the packets through the network.

Mobile and Broadband Services

Digital Subscriber Line (DSL) is mainly used to bring high bandwidth connections to homes and small business's over a copper wire telephone line. This is can only be achieved if you stay within the range of the telephone exchange. DSL offers download rates of up to 6mbps allowing continuous transmission of video, audio and 3D effects. DSL is set to replace ISDN and compete with the cable modem in providing multimedia to homes. DSL works by connecting your telephone line to the telephone office over copper wires that are twisted together.

Asymmetric Digital Subscribers Line is most commonly used for home users. It provides a high download speed but a lower upload speed. Using ADSL, up to 6.1 megabits per second of data can be sent downstream and up to 640 Kbps upstream.

Symmetric Digital Subscriber Line is a digital subcriber line which runs over one pair of copper wires. The main difference between ADSL and SDSL is the difference in upload and download speeds. SDSL allows the same upstream data rate and downstream data rate as ADSL upstream can be very slow.

HDSL High bit-rate Digital Subscriber Line, one of the earliest forms of DSL, is used for wideband digital transmission within a corporate site and between the telephone company and a customer. The main characteristic of HDSL is that that provides equal bandwidth in both directions.

IDSL is a system in which data is transmitted at 128 Kbps on a regular copper telephone line from a user to a destination using digital transmission.

The Local Loop enables operators to connect directly to the consumer via copper local loops and then add their own equipment to offer broadband and other services. This process involves operators accessing local exchange buildings to connect to a network of copper lines which connect them to homes and businesses. BT is an Example of a Local Exchange. The local loop connecting the telephone exchange to most subscribers is capable of carrying frequencies well beyond the 3.4 kHz upper limit.

Benefits of using DSL

DSL can provide a virtual instantaneous transmission of voice, data and video over ordinary copper phone lines. A DSL connection can eliminate delays while waiting to download information and graphics from the Internet. It provides users with a cost effective high speed Internet connection. Another benefit is that a DSL connection is always on-line (like a LAN connection) with no waiting time for dialing or connecting.

There are now more than 10 million broadband connections in the UK. By December 2005 there were 9.792 million broadband connections in the UK and the average broadband take up rate during the three months to December was more than 70,000 per week.
