History and Components of a Modern Mainframe Computer

Mainframe computers are critical for some of the largest corporations in the world. Each mainframe has more than one modern processor, RAM ranging from a few megabytes to multiple-score gigabytes, and disk space and other storage beyond anything on a microcomputer. A mainframe can control multiple tasks and serve thousands of users every second without downtime.

The chief difference between mainframes and other computing systems is the level of processing that takes place. Mainframes are also different in terms of data bandwidth, organization, reliability, and control. Big organizations-banking, healthcare, insurance, and telecom companies, etc.-use mainframes for processing critical commercial data.

In this article, we discuss the evolution of mainframe computers and their components.

History of mainframe computers

IBM developed a critical part of mainframe computing, the Automatic Sequenced Controlled Calculator (ASCC) for arithmetic operations, in 1944. From the late 1950s through the 1970s, several companies manufactured mainframes: IBM, Burroughs, RCA, NCR, General Electric, and Sperry Rand, for example. Since then, System / 390 by IBM is the only kind of mainframe in use. It evolved from IBM's System / 360 in 1960.

An Early mainframe occupied a huge space. New technologies have drastically reduced the size and cost of the hardware. A current-generation mainframe can fit in a small closet.

Components of a modern mainframe computer

Like a PC, a mainframe has many components for processing data: operating system, motherboard or main board, processor, controllers, storage devices, and channels.

• Motherboard: The motherboard of a mainframe computer consists of a printed circuit that allows CPU, RAM, and other hardware components to function together through a concept called "Bus architecture". The motherboard has device slots for input cards and cable interfaces for various external devices. Where PC motherboards use 32- or 64-bit buses, mainframes use 128-bit buses. General instructions regarding the internal architecture help the motherboard connect to the other devices and retrieve data using binary computation.

• Processor: A CPU acts as the central processing point in mainframe architecture and includes an Arithmetic Logic Unit (ALU) for performing arithmetic calculations. It also works as a controller for the bus architecture and handles traffic and data requests. The processing power of mainframes is much higher compared to PCs, so that they can handle huge amounts of data.

• Storage devices: Storage devices are for entering, retrieving, storing, and recording data. Many are external devices, such as hard drives, tape drives, and punch card readers, all connected to terminals of the mainframe and controlled by the CPU. Their capacity for data storage can be hundred or even thousands of times that of a PC.

• Communication controllers: Communication controllers allow remote computers to access a mainframe. With the help of networks, LAN or WAN, communication controllers establish connections with various devices, perform data transmission over communication channels, and keep track of users at terminals.

• Channels: The "channels" are the cables used to connect the CPU and the main storage to other parts of the system and make sure that data is moved in a systematic way without losing its integrity.

Modern mainframes have advanced features such as expanded service management capabilities, cross-platform integration facilities, etc. And so are suitable for critical data center operations. The cost of maintaining modern mainframes is much less compared to older models.

How Useful is CAD Software to Engineers and Architects?

The emergence of advanced technology has made people today dependent on machines. Using computers and software, for example, is a very common illustration of this. Computer experts are coming up with more and more software to make more and more jobs easier.

A more specific illustration of this can be found in the modern approach towards engineering and architecture. These days, professionals in these fields use CAD computer software which is a program that allows them to create designs faster, easier and with more accurate measurements. Aside from the convenience that CAD software brings, it also helps put architects and engineers ahead of their competitors. CAD, which can render designs that are two-dimensional or three dimensional, stands for Computer Aided Design and has been in use since 1982.

So how does CAD computer software work? And what does it do exactly to help engineers and architects? The program is actually multifaceted in the sense that there are many ways it can help. To make CAD work will require, however, a careful study of its features and the many ways it can be used. It is rather a complex yet flexible and highly functional program.

This article will not be enough to discuss the various ways that CAD works but pinpointing its advantages could give some very good ideas. One great advantage of CAD computer software is its easy-to-use tools in the creation and alteration of designs. Obviously, this is so much better than the old fashioned way of using a pencil and eraser directly on paper. This method of designing is obviously so much easier and engineers and architects simply have more time to finish other tasks. In other words, high productivity is going to be the main end result of using CAD.

Before the design is actually printed on paper, CAD also allows both the design professional and the client to preview what has been finished so far. Any alterations can be made simply by manipulating the drawing through the use of the software. With CAD, it is so much easier to spot errors because the designs can be rendered exactly as they would be in reality. Hence, modifications can be done even before printing, thus, allowing one to save.

With the tough competition that everyone has to face these days, it is wise to take advantage of new technologies that can help put them ahead in the race. While traditional methods hold a significant part in the history of design, advanced tools such as CAD software should only be welcomed as man’s way of furthering development in a field of expertise that he himself has created long ago.

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.

10 Top Reasons Why I Have to Upgrade My Computer

The rate at which technology is improving is very fast and in the time you get comfortable with the computer hardware you have bought, several new and improved models appear in the market. While some people prefer to keep their computers state of the art, most of us have a 'If it is not broken, do not fix it' attitude when it comes to upgrading or replacing our computers.

This is a strategy that could prove expensive in the long run. It is always better to upgrade your computer on a regular basis, especially if you have had it for over 2-3 years. Even if your computer has had a large trouble-free existence, you really need to consider periodic upgrades and here are the reasons why you must dos so:

1. Increase in Processing Speed ​​- This is one place where you really get to notice an improvement in performance. If you are upgrading from a Celeron 433MHz processor to a Pentium 4 1.6GHz, you would really notice the difference in performance!

2. Faster Memory Access – Improvements in CPU speed are typically accommodated by improvements in the speed at which data transfer occurs between the CPU and RAM. This is another area that provides an improvement in performance.

3. Size and Capacity improvements – Technology drives a reduction in component size coupled with an increase in storage capacity. This means that a RAM card or hard disk of the similar size as the older ones in your computer could have double the capacity!

4. Software Compatibility – Many of the new software packages you may wish to use in order to improve your productivity or entertainment experience may not function well on you old computer. It is better to upgrade your computer to enjoy the benefits of new software fully.

5. Obsolescence of Hardware – As your hardware gets older; Getting a replacement will get more difficult once manufacturers start phasing out the production. With improvement in technology, the older hardware becomes cheaper initially and becomes expensive as supply dries up.

6. Technical Support Issues – Many manufacturers stop providing technical support for older components as they cease production. The older your computer gets, the harder it is to find help in fixing it when it malfunctions.

7. Development of New Hardware – New hardware products appear in the market frequently that revolutionize your computer experience and are based on newly developed technology. The chances of your old computer supporting new devices are very low.

8. Faster Devices – Your old computer may not be in a position to accommodate the speed at which the new devices communicate.

9. New, Fast Communication Protocols – You may not be able to implement new or faster communication protocols in your old computer because the hardware is unable to support them.

10. Operating System and File Format – Your old hardware may not be able to run newer operating systems and some of the file formats may not be supported.

Determining the Best Type of Fastener to Use For Outdoor Furniture Construction

If you want to learn about selecting hardware for your next outdoor furniture project, then you'll want to read this article. Specifically, I'll be telling you about what type of hardware will perform best, why the type of metal used for fasteners and the finish used are important considerations, and how properly protecting or limiting exposure of your furniture to wet and winter conditions can increase Life span. After you're done with this article you will understand that the best choice of hardware for your outdoor furniture project is dependent on furniture style, material used for construction, selected location for the furniture and budget.

Selecting proper hardware for your furniture will help ensure a long life span, as well as improve the overall appearance of your furniture. Part of the problem is knowing what hardware to select when there are so many options available at the hardware store. The typical Lowes or Home Depot carries a huge selection of stainless steel, hot dipped galvanized, bright galvanized, plain steel, coated steel and brass bolts, nuts, washers and screws. Each type of fastener is suitable for certain applications, but not all are ideal for outdoor furniture applications.

In fact, choosing the wrong fasteners can greatly shorten the lifespan of your furniture, contribute to rot of wood furniture, cause unsightly staining, and even make your furniture unsafe to use.

One thing that needs to be noted right up front is, do not ever use unprotected steel fasteners for outdoor furniture, they will rust very quickly, and the steel will react with the tannic acid in the wood causing streaks and staining. The tannic acid actually speeds up the corrosion of the fasteners. Have you ever seen a wooden fence with black streaks running down the boards from the nails? This fence was installed with the wrong type of fasteners. The same thing will happen to your furniture. Even worse, as the fasteners rust, they will speed up the decay process of the wood around the rusted fasteners, ruining your furniture and making it potentially unsafe to use.

Hot Dipped Galvanized

Screws and bolts treated by hot dipped galvanizing are specifically designed for use outdoors. Electroplated galvanized or bright galvanized fasteners will very well not hold up as well as the hot dipped galvanized hardware. Zinc is used as a coating in both methods, and acts as a barrier against the elements and the tannic acids in the wood.

I strongly recommend only using screws or bolts in the construction of outdoor furniture, however. The galvanized finish on nails, either electroplated or hot dipped, can easily become damaged while hammering them in, exposing the nail head to the elements and allowing them to begin rusting quickly.

Adequate care must be taken when installing galvanized screws. Drill pilot holes in hardwoods, and be sure to use a bit that is not worn and intolerable to skipping in the screw head. For whatever reason, the galvanized screws seem to not be as well tempered as other steel fasteners, and are more likely to either snap off or have the heads strip out while installing them. Due to the permission required for the hot dipped coating, galvanized bolts do not have as tight of tolerance on the threads, and are more likely to strip if over tightened.

Hot dipped galvanized fasteners are a fine choice for many outdoor furniture applications, including Adirondack Chairs, but are not the best choice for use in woods, such as teak.

Stainless steel

Stainless steel is the best choice for use in woods with higher levels of tannic acid, such as teak. Stainless steel is an alloy or blend of steel, nickel and chrome. The ratio of the other metals with the steel determine the weather and corrosion resistance of stainless steel. Because the steel is mixed with other softer metals, the stainless steel is not as strong, so predrilling of screw holes is highly recommended in all applications, and essential in hardwoods such as teak and mahogany. The added corrosion resistance more than outweighs any shortcomings that the metal may have, especially in outdoor furniture applications.

While stainless steel fasteners are the most rust resistant, they are also the most expensive of the options we are discussing. However, using stainless steel fasteners will add years of life to your furniture. In the respect, they are an investment that will pay out for years to come.

Brass

I have seen brass used in some commercially produced outdoor furniture, but do not recommend it. While brass does not form red rust, and is well suited for many wet applications such as toilets and sinks, it does tarnish and corrode. It is also very susceptible to the tannic acids in wood, which will cause it to fail more quickly. Brass screws in particular Do not have sufficient strength for outdoor furniture applications.

Outdoor or deck screws

In the past several years a number of manufacturers have introduced outdoor fastening products specifically marketed for deck building. These will typically be green, gray, tan or brown. These screws are either ceramic or plastic coated to delay the metal reacting with the wood acids. The specific coating methods are proprietary to each manufacturer, and can be a combination of electroplated galvanizing and plastic, or a baked on ceramic.

I have used these fasteners in furniture applications and they perform just fine. Unfortunately, I have not come across bolts with this type of finish. The brand of screw I used was Deck Mate, and they were available in tan and brown, so that the color can be selected to better match the wood being used. These screws are ceramic covered, and the manufacturer provided a coated bit for installation, which was designed to not damage the ceramic coating at the screw head. If you choose this type of fastener, be sure to compare the cost with stainless steel, as the price will vary. If the stainless steel is reasonably comparable in cost, it would be the recommended fastener.

Always be sure to read the manufacturers specifications on the box to be sure that the screws are suitable for your application.

Other Considerations

If you are building furniture that will be located on a covered porch or patio where it will be protected from the elements, the concern will be the interaction between the wood and the fasteners, much more so than the weather. Furniture that will be exposed to the elements all year, such as a garden bench, or an adirondack chair in the corner of your garden, will have to be constructed with much more care and concern to ensure that they hold up more than just one or Two winters.

Additional considerations must be made beyond just the choice of what type of fastener to use, though this is very important. For example, fasteners should not be located where water where collect and sit on the fasteners for an extended period of time. The screws that attach the seat slats to an Adirondack chair are a prime example- typically these screws will be countersunk below the surface of the wood. This will allow water to collect in the screw holes, shortening the life span of all but stainless steel fasteners, and prolonging the exposure of the wood to water, which will increase the rate of decay. In applications where the furniture will be exposed to the elements year round the screw heads should be driven flush with the surface of the surrounding wood.

Construction and design of the furniture are also important considerations. Are the horizontal surfaces of the furniture constructed in such a way that will allow them to shed water, rather than collect it? Think of a picnic table with a slatted or board top. The gaps between the boards allow water a way to run off the top and not pool up.

Conclusion

Stainless steel is usually the best choice for outdoor furniture applications, although the cost may be prohibitive for some. There are other less expensive fastener options available that will perform acceptably. Do not use unprotected steel fasteners for outdoor furniture applications under any circumstances. Know where and how you intend to use your furniture and design it for the conditions it will be subjected to.

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.
