Who Invented Dell Computers?

The invention and the history of the Dell computer is quite interesting. First of all, it was in 1984 when Michael Dell, a student at the University of Texas at Austin, created the company PC's Limited. He only had a starting capital of $ 1,000. So what he did was started working out of his dorm room to build personal computers made from stock components. These computers were to be IBM compatible because that was the standard at that time. If a computer were to function with various pieces of hardware, it needed to be IMB compatible.

It is when Michael Dell figured that selling computers directly to customers to determine customer need that he dropped out of college. His family then extended him the $ 300,000 in expansion capital that he needed to make his business take off.

A success

It was in 1985 that the Turbo PC was developed and it sold for less than $ 800. It contained an Intel 8088 processor that ran at 8 MHz, which is significantly slower than the computers that we use today. Computers today are running in gigahertz, which are hundreds and even thousands of times faster than the 8 MHz processor that Michael Dell was installing in his computers at the time. But the truth is that this was the best that could be done in 1985. The technology was developing.

But there was an aspect of PC's Limited that was unique from the rest and continues to be this way today. It is the fact that customers could order their computers rather than buy a computer that was already assembled. This allowed individuals to receive computers at lower prices than what they could get with their competitors. This definitely worked because PC's Limited grossed $ 73 million in its first year of trading.

The beginning of Dell

It was in 1988 that PC's Limited became Dell. Prior to that, the company already had 11 international operations occurring, so the company was quite large. There were on site services set up to compensate for the lack of businesses acting as service centers for Dell computers. It was in 1990 that Dell attempted to sell through club houses, but had very little success with this. So it is then that Dell went right back to its direct to customer sales.

In 1996, Dell started selling computers on its website. An individual could go onto the website and custom design their computer so that it would be built to their specifications. From there, it would be shipped to the customer's home. Financing was made available so that individuals would be able to acquire their computers easily.

In 1999, Dell became the largest personal computer seller when they took over Compaq computers. Their revenue topped $ 25 billion in 2002. Also in 2002, Dell started selling televisions and other electronic items. They now have Dell brand printers, LCD TVs, and much more. Because of the expansion beyond computers, Dell was changed to Dell Inc. In 2003.

It is amazing that this billion dollar company started in a dorm room with $ 1000 in starting capital. And Michael Dell has always stood by the principles of letting individuals have the capability to design their own machine. Although there are Dell computers now sold in various retail outlets, a person can still go to the website and design the machine of their dreams. And Dell also offers a lot of assistance for individuals needing help with their computers. They offer on-site services and so much more for the computer user so that they can have the best experience possible.

Advantages and Disadvantages of Professional Shopping Cart Software

Advantages & Disadvantages of professional shopping cart software As e-Commerce is becoming a regular technique in the business industry it appears that more and more software development firms are developing professional shopping cart software to be released in the market. There is currently a huge range of free shopping cart software that has been released, and it seems that most e-Commerce website owners prefer these free systems over paid for professional shopping cart software. In this article we are going to look at the advantages and disadvantages of professional shopping cart software.


• Even though you will have to pay for the solution, you get a cart package that has been fully developed, tested and used in the real working world by other e-Commerce websites. If the solution is used by a popular website service then the chances are it has been under more than enough testing to be deemed ready for use.

• Professional shopping cart software will be supported by the people who developed it. A lot of free solutions out there are simply developed and then discontinued as the freelance developers move onto their next project. Support is essential if you are going to want upgrades as mentioned in our next point.

• As the system is supported, the development team are likely to fix any bugs that may occur and provide patches and security fixes. This means the shopping cart software will only get better as time goes on and furthermore improve your e-Commerce website.

• Your site is likely to be more secure when using a professional software solution as in most cases the it developed house private content management systems. This improves security as public content management systems such as WordPress are constantly under threat from hackers as they try to compromise the free source code.

• Another huge advantage of using professionally developed software in e-Commerce is that they will already support a huge range of different payment options for your customers. There are various carts – that only offer PayPal for payment by standard, and it can take a very long time to find plug-ins or figure out how to add other methods yourself. With professional software you can save time and possibly money as it is all included.


• Your e-Commerce venture might be a small time project and professional cart does cost money which you may not have. In this case you may have to make do with a free shopping cart solution. The good part of conducting business online is that after you have made profit with the free system you can reinvest your money to buy a professional package.

• You trust the developers to do everything they promise to ensure the best experience. It might be slightly difficult to use at first and you might have to spend some time getting used to the bespoke system. You also have to understand that you are vulnerable until patches are made if a security flaw is found.

The Role of Technology in Education

In the current age we live in, technology has become an important component. Every day there is some new gadget or software that makes lives easier and improves on the technology and software that already exists. Making lives easier is not, however, the only role technology plays in our lives.

Technology is playing an increasing role in education. As technology advances, it is used to benefit students of all ages in the learning process.

Technology used in the classroom helps students adsorb the material. For example, since some people are visual learners, projection screens linked to computers can allow students to see their notes instead of simply listening to a teacher deliver a lecture.

Software can be used to supplement class curriculum. The programs provide study questions, activities, and even tests and quizzes for a class that can help students continue learning outside the classroom.

Technology has also become part of many curriculums, even outside of computer and technology classes. Students use computers to create presentations and use the Internet to research topics for papers and essays.

Students also learn to use the technology available to them in computer and tech classes. This ensures that after graduation they will be able to use the technology in a work setting, which may put them ahead of someone who did not have access to a particular technology or software in their own school setting.

As technology advances, students have better access to educational opportunities like these. When something new and "better" is disclosed, the "older" technology becomes more affordable, allowing it to be used in educational settings, even when schools are on a tight budget.

Technology has also advanced to help children even before they've started school. Educational video games and systems for young children helps them prepare for school and in some cases get a head start on their education.

There are people who may say children are "spoiled" by technology. Instead of being able to add a long column of numbers in their heads, for example, they turn to a calculator. Regardless of these arguments, technology is an important part of today's society. By incorporating it into the classroom, students will be better equipped to transition from the classroom to the work place.

The Importance Of Excel In The Workplace

Excel is perhaps the most important computer software program used in the workplace today. That’s why so many workers and prospective employees are required to learn Excel in order to enter or remain in the workplace.

From the viewpoint of the employer, particularly those in the field of information systems, the use of Excel as an end-user computing tool is essential. Not only are many business professionals using Excel to perform everyday functional tasks in the workplace, an increasing number of employers rely on Excel for decision support.

In general, Excel dominates the spreadsheet product industry with a market share estimated at 90 percent. Excel 2007 has the capacity for spreadsheets of up to a million rows by 16,000 columns, enabling the user to import and work with massive amounts of data and achieve faster calculation performance than ever before.

Outside the workplace, Excel is in broad use for everyday problem solving.

Let’s say you have a home office. You can use Excel to calculate sales tax on a purchase, calculate the cost of a trip by car, create a temperature converter, calculate the price of pizza per square inch and do analysis of inputted data. You can track your debt, income and assets, determine your debt to income ratio, calculate your net worth, and use this information to prepare for the process of applying for a mortgage on a new house. The personal uses for Excel are almost as endless as the business uses for this software – and an Excel tutorial delves into the practical uses of the program for personal and business use.

The use of spreadsheets on computers is not new. Spreadsheets, in electronic form, have been in existence since before the introduction of the personal computer. Forerunners to Excel and Lotus 1-2-3 were packages such as VisiCalc, developed and modeled on the accountant’s financial ledger. Since 1987, spreadsheet programs have been impacting the business world. Along the way, computerized spreadsheets have become a pervasive and increasingly effective tool for comparative data analysis throughout the world.

Today, end users employ Excel to create and modify spreadsheets as well as to author web pages with links and complex formatting specifications. They create macros and scripts. While some of these programs are small, one-shot calculations, many are much more critical and affect significant financial decisions and business transactions.

Widely used by businesses, service agencies, volunteer groups, private sector organizations, scientists, students, educators, trainers, researchers, journalists, accountants and others, Microsoft Excel has become a staple of end users and business professionals.

The beauty of Excel is that it can be used as a receiver of workplace or business data, or as a calculator, a decision support tool, a data converter or even a display spreadsheet for information interpretation. Excel can create a chart or graph, operate in conjunction with Mail Merge functions, import data from the Internet, create a concept map and sequentially rank information by importance.

Excel offers new data analysis and visualization tools that assist in analyzing information, spotting trends and accessing information more easily than in the past. Using conditional formatting with rich data display schemes, you can evaluate and illustrate important trends and highlight exceptions with colored gradients, data bars and icons.

Indeed, Excel can be customized to perform such a wide variety of functions that many businesses can’t operate without it. Excel training has become mandatory in many workplaces; in fact, computer software training is a must for any workplace trying to keep up with the times.

Let’s say you’re an employer with 97 workers, 17 of whom called in sick today, and you want to know the percentage represented by absentees. Excel can do that. You can learn Excel and use it to determine the ratio of male to female employees, the percentage of minorities on the payroll, and the ranking of each worker by compensation package amount, including the percentages of that package according to pay and benefits. You can use Excel to keep track of production by department, information that may assist you in future development plans. You can create additional spreadsheets to track data on vendors and customers while maintaining an ongoing inventory of product stock.

Let’s say you want to know your business production versus cost. You don’t have to be a math wiz – you just have to learn Excel. Excel allows you to input all of the data, analyze it, sort it according to your customized format, and display the results with color, shading, backgrounds, icons and other gimmicks that offer time-saving assistance in later locating precisely the information desired. If this spreadsheet is for presentation purposes, Excel helps you put it together in such a visually appealing way that the data may seem to pop and sparkle.

The single most important thing an employer may do is learn Excel – it is one of the most essential tools of the workplace.

Why Architectural Drafting Is Common in Architectural Design

For architectural design projects, while there is the emphasis on using 3D models and architectural BIM modeling, the time-tested practice of using architectural drafting and 2D technical drawings is still commonplace in the AEC industry. Architectural drafting has evolved from the drawing board to computer-aided design and drafting (CAD) software programs. Drafting practices help to provide architectural construction drawings that include the technical details of architectural, structural and electrical elements required for the construction of a building. To understand the stage at which architectural drafting takes place, the workflow of a building design lifecycle must be considered.

The basic workflow of an architectural design project starts with the architect creating a conceptual plan which is usually modelled into architectural 3D models and rendered as photorealistic images for marketing and presentation to clients and customers.

Once the conceptual design is approved by the client, the design is then progressed into more detail and shared with other parties such as structural and MEP engineers. The way in which the design is progressed for the ‘design development’ phase by an architect lends itself to two options, either to develop a 3D model with more detail and then create subsequent sheets and details using a 3D tool such as Revit or AutoCAD, or as is still commonplace, to develop the concept design in 2D using more traditional methods. From the conceptual plans provided by architects and engineers, a drafter can convert these designs using CAD software programs to create technical drawings.

Architectural drafting is the process of creating technical drawings which include the floor plan, sections, elevations, detailed drawings and other documents in a construction drawing set (CD Set), which are typically required for the construction of a building.

The difference between Architectural Drafting and Modelling

Architectural drafting refers to creating 2D technical drawings and architectural construction drawings which are mainly used by contractors and consultants on site. Architectural 3D modelling refers to creating 3D models and renders of photorealistic images which are mainly used to present the architectural design for marketing purposes and then progressed from there to create the 2D technical drawings, in effect feeling like an extra stage (the 3D modelling element). The main software used for drafting, to create 2D technical drawings is AutoCAD while modellers use Revit and ArchiCAD to create 3D models and rendered images. Architectural draftsmen need to have basic 2D and 3D software knowledge such as AutoCAD and knowledge of technical codes and drafting guidelines specified by organisations such as American National Standards Institute (ANSI), American Society of Mechanical Engineers (ASME), American Design Drafting Association (ADDA), Public Works Government Services Canada (PWGSC), National Institute of Building Sciences (NIBS), BSI British Standards Institute and Standards Australia Code AS1100. Architectural modellers need to have a deeper understanding of architectural, building and construction concepts and experience with 3D software programs such as Revit and ArchiCAD.

Why Architectural Drafting is still Common in Architectural Design Practices

Architectural 3D models are preferred by architects and designers because they provide a 3D perspective of the conceptual plan of the building; it makes management of project data easier and allows for design changes on the go. However, construction companies that require technical specifications of the architectural project prefer 2D technical drawings and architectural construction drawings because they provide accurate details required for construction, most of the resources involved in construction understand 2D drawings, there are no issues with compatibility of software as compared to when using 3D models and it is a suitable solution to meet the budgetary requirements of a construction project. Some of the reasons why architectural drafting is preferable by several construction companies include:

• Suitable as per construction requirements – In some building projects, 2D technical drawings or architectural CAD drawings are sufficient to complete construction, where additional information that 3D models provide is not required. A construction drawing set (CD set) includes all the floor plans, elevations, sections and detailed drawings required for construction. Technical codes, symbols and other additional information such as the type of material are provided in technical drawings. Therefore, construction companies find 2D technical drawings sufficient to successfully complete construction.

• Availability of technical resources – Not all companies have technical resources to deliver 3D models. While drafting teams are qualified to work on AutoCAD to deliver 2D technical drawings, they may not be qualified to work on Revit to deliver 3D models. In the construction industry, the availability of drafting teams who can provide 2D technical drawings is ample compared to companies that provide 3D modelling services.

• Availability of software – The adoption of new software and practices is gradual and slow in the construction industry. The software used in building projects varies from country to country. Some countries use ArchiCAD and AutoCAD Architecture instead of Revit, therefore leading to the incompatibility of project data. 2D technical drawings in AutoCAD are widely used and compatible making it a preferred option to Revit 3D models.

• Suitable as per cost and budgetary requirements – In most cases, construction companies do not find the need to invest more in 3D models, when drafting solutions provide detailed technical drawings which are sufficient and relevant enough for construction. There is also the added investment in resources that are competent enough to understand and implement architectural 3d models on-site.

While architectural 3D modelling and BIM modelling provide design-related information typically required for architects and designers in the design stage of the building project lifecycle, architectural drafting provides technical drawings that are not just about aesthetics but about high-performance detailing of construction elements. Architectural CAD drawings specifically communicate the design intent and help in the construction of buildings which companies find relevantly sufficient over 3D models. Even as construction companies will need to eventually evolve to combining the use of 2D technical drawings and architectural 3D models until then, the time-tested practice of using architectural drafting and drawing solutions in construction is here to stay.

Introduction to Silk Test Architecture

Normal use of an application consists of a person manipulating a keyboard and mouse to initiate application operations. The person is said to be interacting with the GUI (Graphical User Interface). During Silk Test testing, Silk Test interacts with the GUI to submit operations to the application automatically.

Thus Silk Test can simulate the actions of a person who is exercising all the capabilities of an application and verifying the results of each operation. The simulated user (Silk test) is said to be driving the application. The application under test reacts to the simulated user exactly as it would react to a human rest. Silk Test consists of two distinct software components that execute in separate processes:

The Silk Test host software

The 4Test Agent software

Silk Test host software

The Silk Test host software is the program you use to develop, edit, compile, run and debug your 4Test scripts and test plans. This manual refers to the system that runs this program as the host machine or the Silk Test machine.

The Agent

The 4Test Agent is the software process that translates the commands in your 4Test scripts into GUI-specific commands. In order words, it is the Agent that actually drives and monitors the application you are testing. One Agent can run locally on the host machine. In a networked environment, any number of Agents can run on remote machines. This manual refers to the systems that run remote Agents as target machines. This manual refers to the systems that run remote Agents as target machines. In a client/server environment, Silk Test drives the client application by means of an Agent process running on each application’s machine. The application then drives the server just as it always does. Silk Test is also capable of driving the GUI belonging to a server or of directly driving a server database by running scripts that submit SQL statements to the database. These methods o directly manipulating the server application are intended to support testing in which the client application drives the server.

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.

The Advantages and Disadvantages to Bug Tracking Software

Bug tracking has been around as early as the 1940’s, just not in a software form. In these early days, simply using a pen and a paper created tracking systems. It evolved from then to using spreadsheets. Now there is bug tracking software like the defect tracking tool and even more specific programs like Mantis and Bugzilla, just to name a couple. As with anything that evolves however, there will always be those that are 100% for the programs and those that are against it. This article will cover all claims – both positive and negative – of bug tracking software like the defect tracking tool.

The Positive Claims

It certainly depends on the type of bug tracking software that is used, but it seems as if there are many more advantages to these tools than disadvantages. The most obvious advantage is that these types of tools allow companies to keep a record of the issues that are recorded, who fixed them, and even how long it took to fix the issue for some types of programs. Customers are encouraged to be as detailed as they can be when requesting that an issue be fixed so that companies can complete their requests as quickly as possible. The fact that the issues are recorded and saved is a huge benefit for the companies because sending the recorded bug list with the purchased software is a common practice. This is a benefit to customers because if it is a common error, they can simply look up this issue in the previously recorded bug list. However, if the list is incredibly long (a common disadvantage) it can become more of a hassle.

The Negative Claims

As with anything that has a list of positive aspects there is also a list of negative aspects, though there are few. One of the biggest complaints is not so much from the bug tracking software or defect tracking tool itself but more from the process of submitting issue requests. Customers need to be extremely detailed with their issue requests if they want a detailed response. Miscommunication isn’t a fault of the product, the customer, or the company – it’s simply something that happens. Customers and companies alike both need to remember to be patient with each other and to treat each other with a mutual respect. A second complaint that was previously mentioned is the length of issues in some of these software programs.

Some customers don’t have the patience to look through a long list of software issues that have been previously recorded and this causes frustration among the companies that took the time to purchase software that saves them. The length of issues that are submitted can also become a problem because if there are too many issues submitted and not enough engineers to address them, some can get overlooked. Nobody likes to be forgotten, but usually these types of bug tracking software include detailed instructions and are easy to use.

Usually when a company purchases a bug tracking software or defect tracking tool it already has an experienced IT department in place. Whatever the software is that is being used with these programs should have some sort of backup for when the work is completed so it does not get lost if the issues that occur are deadly.

Advantages and Disadvantages of Biometric Time and Attendance Software

First of all let me ask you what you understand by time and attendance software? Have you ever been asked to log in as soon as you enter office and the main gate of the office has a Biometric machine that takes in your finger prints and allows you to enter the office premise? Yes, these are the time and attendance software being installed in a company.

Biometrics consists of methods for uniquely identifying a person (human being) by his/her physical or behavioral traits. There are many biometric software available in market for such purpose and their use is widely known. One such use is Biometric time and attendance management software.

Those days are gone when we had to punch in cards or sign into a register to tell the other person that we are present. Just as paper checking has been changed from manual to computerized, identifying a person and letting him in your office has been changed from manual to biometrics.

There are many benefits of having such methodology in your office. Such as:

• Accurate timing: When a person looks at his watch and enters the time there is a slight chance that he may see the wrong timing and write. Whereas with biometric time and attendance software there is no possibility of such mistake. The user does not need to see or check the time, it automatically gets logged in.

• Less error: There is no scope of human error here.

• Profit to company: If it’s accurate and correct the company will definitely gain from it.

As everything has a good and bad side this too has its disadvantages, such as:

• Extra cost to company: Biometric software and machine cost a lot more, so installing such software need a good investment money wise.

• Extra management: Remember when every employee is logging his own timing when he comes or leaves; there is no extra management here. But, if you are putting a machine there has to be taken some care of it.

Biometrics time and management software is really helpful when creating payrolls for employees. Once a definite timing has been registered you don’t need to think twice before creating the employees pay.

Many homes are also using such kind of software to have a safe and secure home. Biometric software is really helpful when you need security in your home as well as in office. There are many companies all over the world providing such biometric time and attendance software. You just need to keep an eye on the technologies and websites that are providing you these.
