An Introduction To The World Of EPOS Software

EPOS software is used on a computer-based electronic point of sale system that allows you to facilitate a selection of different operations at a checkout counter. By offering the owner of the point of sale system the ability to complete duties including stock control, monthly reporting and advanced sales transactions, EPOS software becomes useful since it basically automates what has been traditionally completed by staff. Because of this, EPOS software is an amazing tool for any business as it can help to improve efficiency by making tasks far more easy to complete – and this, naturally, can certainly benefit productivity and sales.

eposShould all retail establishments utilize POS software? It is very important point out that although this software has numerous significant advantages, it is rather expensive and therefore is not a viable option for all organizations. After all, you might end up paying more for EPOS retail software than what you earn, draining your organization of profits and that is not a good thing. When your business generates an annual income of around $700,000 or more, then, as stated by internet auction giant, you will more than likely do well from having a point of sale terminal. Implementing manual operations management will provide a much better return on investment if your salary is below this threshold. But bare in mind that there is a huge variety of point of sale systems out there, so there is a chance that there is an option out there that can provide a more tailored solution. Because the majority of systems are designed for big businesses, this will lead smaller firms to miss out on smaller and potentially profitable solutions.

You’ll notice different EPOS software and systems out there, the most well-liked companies associated with their development of which are IBM, Fujitsu, Panasonic, MICROS Systems, Squirrel Systems, Microinvest, and Radiant Systems. The hardware which usually comes with a point of sale terminal includes a credit card reader, bar code scanner, cash drawer, card swiper (with pin pad), as well as a receipt printer. The system will also need a network (usually internet-based) which can operate on a wired or wireless systems.

EPOS software and systems can vary a great deal in price because there are so many different types – from simple to advanced. Price differences are mainly guided by the brand you are interested in, as well as the specific components of a system. For instance, a more elaborate EPOS system obviously is often more expensive when compared with a basic one. A solid system will generally set you back between $2000 and $7000. If you have to work with a budget, don’t hesitate to shop around for a cheaper seller offering discounted EPOS systems because you can bring the purchase price down to $1,500. The provider of a good point of sale system should be able to give you a great deal on EPOS software. Most of the time after buying the device, the company which you bought it from will be able to set it up too. Don’t forget to clarify though if installation is on the market for free or with an added charge.

How Does Network Access Control Work?

One thing that is often used but not completely understood is a network access control. Network access control, or NAC, is basically a computer networking solution which uses a set of specific protocols in order to define and implement policies dealing with controlling access to a network. There are network nodes in devices that find and access a network. But companies, businesses, and individual network administrators don’t want just anyone being able to access their network at any given point. This is where a network access management system comes into play.

How Does It Work?

To put things simply, computers and other devices are not allowed to access a network unless they meet the individual policies of a business. Many businesses require an anti-virus protection level met and a system update level in order to allow access. This way the network is protected from threats that are common when there are a lot of different computers and devices seeking access. While a computer is being checked to see if the policies are met with a software agent, it resolves any issues that are found immediately. Once everything defined by the NAC system is met, the user is then allowed access.

Even after access is granted to a network, there are still other policies and controls put into place that dictate where the user is allowed to go within that network. For instance, someone in the Human Resource department are given a certain profile that allows that user access to areas others are not such as employee information. Many businesses allow users from a department to only view their department information as well.

Using NAC is also possible with a wireless network. Not everyone is wired in, especially with the use of devices increasing. It may slow down the speed of the internet a bit, but this just means employers need to find a balance between their policies and making sure their speeds are enough that productivity stays up.

What Does Network Access Control Do and Why Get It?

The first and main goal of this is just like the name states- to control any access to a network. This is accomplished through policies that include pre-admission endpoint security policy checks and some post-admission controls over users and devices with where on the network they can go and what they can do.

Another function of the NAC is to help in the security area of the network. As specified before, users must meet minimum requirements that ensure they won’t contaminate the network through virus. The end-stations are equipped to prevent this from happening with antivirus, host intrusion prevention software, and patches. When a network becomes infected, cross-contamination is entirely possible through what is called computer worms.

Conventionally IP networks will enforce their access policies with IP addresses. NAC does it differently with identities that are authenticated user identities. This is especially true of user end-stations like desktop computers and laptops. Some businesses, colleges, and universities will use their NAC systems to ban legal and illegal file sharing applications.

3D Model Software In Medical Training

Once upon a time, to understand the make-up and function of the human body, just to observe its normal, healthy function, let alone to identify cause and effect of disease or injury, a medical practitioner had to cut the body open just to see its organs and bones and other tissue. This observation, however, usually meant the death of the subject, so those practicing the medical arts worked with cadavers. This practice continues today.

However, modern medicine has been able to access the interior of the human body and observe functions in a living being because we are able to sustain life with various technologies not possible in antiquity. The problem with that method is that there are not enough living humans who need such surgical procedures just to educate medical practitioners in their healing arts. The sanctity of human life is too precious to ask thousands of individuals to surrender to the knife at a cost no one wants to bear.

Fortunately, the advent of 3D model software has come to the rescue of educators and students alike. The ability to render not just individual organs and other tissues, but to combine them into one single, comprehensive model of the entire human body is virtually miraculous to the student of even twenty or thirty years ago.

But the abilities of 3D model software exceed that. It is also possible to render and visually manipulate position and orientation of any organ as a solid or as a shell model. It is possible to render several organs together that function as a complex system, such as the heart and lungs, or the mouth and stomach, the brain and nervous system, the entire circulatory, respiratory, nervous, digestive, or reproductive systems.

Better yet, these systems can be animated, such that we can observe the beating heart, the breathing lungs, or muscular action. A medical teacher can show a student the entire function of the heart in real time or in slow motion or accelerated motion. Factors such as fluid pressure and viscosity can be added to the model to demonstrate vascular blood flow.  Factors of tissue density and range of motion can be added to the model, then animated to demonstrate heart muscle contraction and relaxation. Factors of stress on the heart by external influences such as heavy breathing, or excessive body weight can be added to observe those effects on the heart.

The miracle continues. A CAT-scan will show an organ, or the entire human body. If there is an observed tumor in the brain, for example, the CAT-scan showing the tumor can be converted in 3D model software that can then be manipulated to show the surgeon the best, most accurate and least invasive and potentially destructive path to the tumor to eradicate or extract it.

All this is possible in 3D model software without requiring a single body or scalpel, but it is all based on the pioneering efforts of those who depended on those tools to establish the parameters by which the human body functions.
