Advantages of Antispyware Programs

Much like the antivirus programs, now a days anti spyware programs also is a must if you are browsing the net. Most of the antivirus programs provide a good job by taking care of the computer viruses. However, many of them fail to detect the spyware which gets installed onto the PC when connected to the internet. This is where Anti spyware programs comes to help. They do a good job by protecting our computers by identifying the spyware and promptly remove them.

There are so many antispyware programs are available in the market. Both in the Online as well as near to your computer retail showroom. However, you have to ensure that you buy a good Anti spyware program which fulfills the requirements what it promises. Also, make sure to check that the software works on your Operating System. Most of them work on Windows Operating system; however, there is no harm in double checking the same.

Some of the characteristics of a good antispyware program is as below.

Real time scanning

Real time scanning is the heart of these type of programs. The program once installed should reside on your system tray and should be able to do a real time scan in the background. This way it should be able to identify all kinds of threats like Adware, spyware, Trojans and the harmful key loggers.

Automatic Updates

There is no point in having an Antispyware software program which does not update the spyware definitions automatically and at periodic intervals.

Customer Support

Most of the time you will not be require to call up their helpdesk as the software will work automatically provided if the operating system is compatible and all the installation prerequisites are met. However, if you run across any installation problems or some kind of bugs customer service comes in handy.

Computer Hardware Course – The Advantages of Taking It

Computer hardware courses are an excellent way to learn how to manage the inevitable computer failures that you will encounter as you find yourself hanging on your computer more and more everyday. While you do have the option of taking your computer to the service center it can cost you a lot of time and money. Your computer hardware course is invaluable for helping you understand the hardware requirements for your computer that will be enable you to jump to the rescue instead of trudging along to the repair shop.

It does not take an engineer or a technician to be successful in learning about computer hardware. If you are interested in engineering or technician positions however, a background in computer hardware can make you a far more valuable person in your field and can enhance your employability tremendously.

To troubleshoot your computer you can do very well with a simple computer hardware course. You can become your own specialist and forgo spending the money on an IT specialist.

The time invested in a computer hardware study program will pay off quickly when things go wrong. But, this is not the only reason taking a computer hardware course would be a good plan.

Not only will you be able to fix your computer, but you will have the knowledge to build a computer from scratch. The cost of computer parts is often far less expensive than buying a pre-made package. You will also be able to customize your computer so that it is perfectly designed for your needs.

By avoiding the cost of labor from the computer store you will have a far less expensive computer that is perfect for you. You will also no longer need to worry about taking your computer in for repairs as you will know just how to fix what goes wrong.

Computer knowledge is in high demand no matter what career you are involved in. With the information you learn in a computer hardware course you will be able to take on an IT position. Such positions are in high demand as a limited number of people have the knowledge to take on an IT role.

The time needed to take a computer hardware course is well worth the investment. Learning about software and programming can only make you even better with your computer goals. If you are limited in time, not to worry. Many courses are available online or on CD for you to do at home.

3 Main Causes of Kernel Errors

A kernel error is a failure in some code critical to Windows. If you have ever encountered a Blue Screen of Death (BSoD), then you have seen a kernel error. Windows is actually several layers of programs made to work together. You can think of Windows as if it were your body, with many pieces working together to make a whole, and, like your body, some parts of Windows are more important than others.

The kernel is the most important part of Windows. It includes critical programs to handle things like memory management and device drivers for the graphics card. These programs are like a body's heart and brain. If something in the kernel crashes, it will often cause all of Windows to crash.

Software Failures

Because there are a lot of programs in the kernel, there are many opportunities for bugs to appear. Although Microsoft does extensive testing to get rid of bugs, their testing facilities can not run through all the combinations that billions of computers use with Windows when some bugs get through.

However, many of the kernel failures are in device drivers written by companies that make hardware, not by Microsoft. Your graphics card, for example, probably uses a driver created by the video company. These companies often work with Microsoft to test their drivers, but having companies working together adds an additional layer of complexity.

Hardware Failures

A hardware failure can cause a kernel error. If your graphics card fails, it can send bad data to the graphics device driver, which then crashes, creating a kernel error. If your hard disk fails, it can corrupt files used by Windows and cause the programs that use those files to crash.

Registry Failures

Registry failures can cause kernel errors. The registry is a database of information that Windows uses to store information about programs. If the registry gets corrupt, the programs that use it can cause kernel errors.

Registry corruption can come from either software or hardware failures. Software corruption can come from a bug in one of the programs that writes information out to the registry. Or if you turn off your computer without doing a complete shutdown, the registry files may not get completely written to the disk. Hardware corruption can happen when the hard disk fails causing parts of the registry files to be lost. It's a good idea to do some research on kernel errors and other registry issues.

Why Do We Need Software Engineering?

To understand the necessity for software engineering, we must pause briefly to look back at the recent history of computing. This history will help us to understand the problems that started to become obvious in the late sixties and early seventies, and the solutions that have led to the creation of the field of software engineering. These problems were referred to by some as “The software Crisis,” so named for the symptoms of the problem. The situation might also been called “The Complexity Barrier,” so named for the primary cause of the problems. Some refer to the software crisis in the past tense. The crisis is far from over, but thanks to the development of many new techniques that are now included under the title of software engineering, we have made and are continuing to make progress.

In the early days of computing the primary concern was with building or acquiring the hardware. Software was almost expected to take care of itself. The consensus held that “hardware” is “hard” to change, while “software” is “soft,” or easy to change. According, most people in the industry carefully planned hardware development but gave considerably less forethought to the software. If the software didn’t work, they believed, it would be easy enough to change it until it did work. In that case, why make the effort to plan?

The cost of software amounted to such a small fraction of the cost of the hardware that no one considered it very important to manage its development. Everyone, however, saw the importance of producing programs that were efficient and ran fast because this saved time on the expensive hardware. People time was assumed to save machine time. Making the people process efficient received little priority.

This approach proved satisfactory in the early days of computing, when the software was simple. However, as computing matured, programs became more complex and projects grew larger whereas programs had since been routinely specified, written, operated, and maintained all by the same person, programs began to be developed by teams of programmers to meet someone else’s expectations.

Individual effort gave way to team effort. Communication and coordination which once went on within the head of one person had to occur between the heads of many persons, making the whole process very much more complicated. As a result, communication, management, planning and documentation became critical.

Consider this analogy: a carpenter might work alone to build a simple house for himself or herself without more than a general concept of a plan. He or she could work things out or make adjustments as the work progressed. That’s how early programs were written. But if the home is more elaborate, or if it is built for someone else, the carpenter has to plan more carefully how the house is to be built. Plans need to be reviewed with the future owner before construction starts. And if the house is to be built by many carpenters, the whole project certainly has to be planned before work starts so that as one carpenter builds one part of the house, another is not building the other side of a different house. Scheduling becomes a key element so that cement contractors pour the basement walls before the carpenters start the framing. As the house becomes more complex and more people’s work has to be coordinated, blueprints and management plans are required.

As programs became more complex, the early methods used to make blueprints (flowcharts) were no longer satisfactory to represent this greater complexity. And thus it became difficult for one person who needed a program written to convey to another person, the programmer, just what was wanted, or for programmers to convey to each other what they were doing. In fact, without better methods of representation it became difficult for even one programmer to keep track of what he or she is doing.

The times required to write programs and their costs began to exceed to all estimates. It was not unusual for systems to cost more than twice what had been estimated and to take weeks, months or years longer than expected to complete. The systems turned over to the client frequently did not work correctly because the money or time had run out before the programs could be made to work as originally intended. Or the program was so complex that every attempt to fix a problem produced more problems than it fixed. As clients finally saw what they were getting, they often changed their minds about what they wanted. At least one very large military software systems project costing several hundred million dollars was abandoned because it could never be made to work properly.

The quality of programs also became a big concern. As computers and their programs were used for more vital tasks, like monitoring life support equipment, program quality took on new meaning. Since we had increased our dependency on computers and in many cases could no longer get along without them, we discovered how important it is that they work correctly.

Making a change within a complex program turned out to be very expensive. Often even to get the program to do something slightly different was so hard that it was easier to throw out the old program and start over. This, of course, was costly. Part of the evolution in the software engineering approach was learning to develop systems that are built well enough the first time so that simple changes can be made easily.

At the same time, hardware was growing ever less expensive. Tubes were replaced by transistors and transistors were replaced by integrated circuits until micro computers costing less than three thousand dollars have become several million dollars. As an indication of how fast change was occurring, the cost of a given amount of computing decreases by one half every two years. Given this realignment, the times and costs to develop the software were no longer so small, compared to the hardware, that they could be ignored.

As the cost of hardware plummeted, software continued to be written by humans, whose wages were rising. The savings from productivity improvements in software development from the use of assemblers, compilers, and data base management systems did not proceed as rapidly as the savings in hardware costs. Indeed, today software costs not only can no longer be ignored, they have become larger than the hardware costs. Some current developments, such as nonprocedural (fourth generation) languages and the use of artificial intelligence (fifth generation), show promise of increasing software development productivity, but we are only beginning to see their potential.

Another problem was that in the past programs were often before it was fully understood what the program needed to do. Once the program had been written, the client began to express dissatisfaction. And if the client is dissatisfied, ultimately the producer, too, was unhappy. As time went by software developers learned to lay out with paper and pencil exactly what they intended to do before starting. Then they could review the plans with the client to see if they met the client’s expectations. It is simpler and less expensive to make changes to this paper-and-pencil version than to make them after the system has been built. Using good planning makes it less likely that changes will have to be made once the program is finished.

Unfortunately, until several years ago no good method of representation existed to describe satisfactorily systems as complex as those that are being developed today. The only good representation of what the product will look like was the finished product itself. Developers could not show clients what they were planning. And clients could not see whether what the software was what they wanted until it was finally built. Then it was too expensive to change.

Again, consider the analogy of building construction. An architect can draw a floor plan. The client can usually gain some understanding of what the architect has planned and give feed back as to whether it is appropriate. Floor plans are reasonably easy for the layperson to understand because most people are familiar with the drawings representing geometrical objects. The architect and the client share common concepts about space and geometry. But the software engineer must represent for the client a system involving logic and information processing. Since they do not already have a language of common concepts, the software engineer must teach a new language to the client before they can communicate.

Moreover, it is important that this language be simple so it can be learned quickly.

How to Repair DBF Files by Using DBF Recovery Software

As a computer user you must have heard about a DBF file or some of you have used it. DBF is a database file format used by various database software programs, such as: Visual FoxPro, Clipper, dbFast, CodeBase, MultiBase, dbXL, Arago and similar database programs. A database file is a collection of data organized in a tabular form. A DBF file can be easily opened, edited and saved by any of these database programs therefore, this file format is very popular among computer users.

The most common use of a database file is to store a large amount of data and information. The file is widely used in almost every sector, such as: corporate and educational sectors to store the data and information. It has become an essential file format for an individual and an organization.

Where this file format is very useful for users on the other hand, it may create some serious problems as well. Sometimes a DBF file may become inaccessible or invalid due to corruption. DBF is not immune to corruption; in fact, this file format is prone to corruption due to its large size and complex file structure. It might be easily corrupted due to various reasons, such as: virus attacks, malfunction in database application, hard disk drive failure, software collision, unexpected cancellation of DBF, human errors and many more. These are some common reasons which can play an important role in database file corruption.

While opening a corrupt DBF file you may receive some error messages something like these:

  • “File .dbf does not exist”.
  • “The fields in table did not match the entries in the database”.
  • “Access to table disabled due to previous error”.
  • “Database file appears corrupt: Page is of wrong type.
  • “Corrupt table”/ “index header”.
  • “Filename .dbf has become corrupted”.

These are some common errors which frequently take place at the time of corruption. For example: you are working on your DBF file, everything is fine. But all of a sudden your database application (Visual FoxPro or other) starts hanging. You have no other option other than restarting the system. But when you restart your system and open the same DBF file, in which you were working earlier, it does not open or you get an error message saying the file is corrupted or damaged. This must be very frustrating situation for any user since all the hard work will go into the vain. All the data and information stored in the file might be lost forever. You have to re-create the file, which might not be possible in some cases.

In such critical state a BKF file will definitely help you. If you have backed up the database file (which is now corrupted), then you can easily restore it from the BKF file. But sometimes the BKF file may not be available or corrupted or invalid. In this situation you can use third-party DBF recovery software. This is one of the most efficient and effective solutions to fix corrupt DBF files. The DBF recovery software is designed to repair an extremely corrupted DBF file and to restore maximum data from it. It is highly capable to resolve or fix all the errors from corrupted DBF files. The software supports all popular database applications, such as: dBase III, dBase IV, dBase V, Visual FoxPro, Clipper, dBFast, CodeBase, MultiBase, dBXL and Arago. The best feature of the software is its self-describing user interface. It requires no technical knowledge or skills to use this software. Any tech savvy and a novice user can easily and comfortably use this software to repair corrupted DBF files. The DBF Recovery software is available with free demo version. Users can download the demo version before buying the full software. This helps users to examine the features and performance.

How to Change the MPI Node Address For a Siemens S7-300 PLC

I have seven Siemens S7-300 PLCs connected together using the MPI (Multi Point Interface) interface. The Siemens MPI protocol is used by Siemens PLCs to communicate with external devices. I want to rename each of the seven PLCs. Here are the steps to accomplish that task.

First, connect your MPI cable to the first PLC. I will be connecting my laptop to each PLC individually. Power up the PLC and open Simatic Manager. The "New Project" Wizard window will open. Just click Cancel to close the window. Now click the Accessible Nodes icon on the toolbar. A window will open showing the identification of the PLC you are connected to. My window is showing MPI = 2 (directly). Make a note of this address and close the window.

Next we need to download a hardware configuration to the PLC. This is where we will rename the PLC node address. There are probably a couple of different ways to do this – following is how I accomplish this. All seven of my PLCs are the same model; Therefore, I am using the same hardware configuration. For the obvious reasons, I want to give each a different MPI node address. I have a project file that contains all seven of my PLC programs and one hardware configuration file. I open the one hardware configuration file, and then double click Hardware in the right hand window. This will open the HW Configuration window. In this window you should see your PLC with its MPI address given.

Remember when we clicked the Accessible Nodes icon and saw MPI = 2 (directly)? My Hardware Configuration Window is showing a MPI address of 7. Place your mouse cursor on the 7 and double click. Your CPU Properties window will open. It should open to the General tab. Look down and you will see Interface Type MPI with an address of 7. Click Properties and the MPI interface Properties window will open. Using the pull down menu, choose your MPI node address and make sure the MPI (1) 187.5kbps is highlighted and click OK. You are now back on the CPU Properties window where you will see your address has changed. Click OK and you will go back to the Hard Ware window where you can verify your MPI node address has changed.

You will now click the Save and Compile icon and then click the download icon. The Select Target Module window will open. Click OK and the Select Node Address window will open. Here you will see the MPI node address you assigned earlier. You will need to click the View button right below this. You will see the current node address appear, this should be the same as what you saw earlier when you clicked the Accessible Nodes icon. Simply click on this number and you will see it appear in the MPI address slot under the Enter connection to target station. Click OK and the Download to Module window will open. Click OK and the Stop Target Modules window will open. Click OK and the "Do you want to start the module?" Window will open. Click Yes.

Now go back to the SIMATIC Manager window and click the accessible nodes icon. You will see your new MPI node address. You can see this same article with pictures at http://www.morerobototics.com .

How Has Technology Changed Art?

We all are witnessing the changes being made in the art these days. Technology has the power to change anything. It is changing the traditional art into digital art.

Amazing digital art has taken place of traditional art. Digital art is exploring itself in many different ways that one can imagine. Different software is developed to increase the presence of digital art.

Photoshop Artists are one of the most common digital artists who give an amazing look to a picture with the help of imaging software and different applications.

These applications are developed with the help of technology. Anyone can be a digital artist having knowledge and proficiency in Photoshop.

Difference between traditional artists and digital artists is that traditional artists use paint and cement for their art and digital artists use imaging software and applications in their art. Some of the applications have the power to create 3D art work.

Technology has taken art into a new level of creativity. Let us talk about how technology has changed traditional art into digital art. We know that internet is ruling the world with its power. So, artists decided to present their art online with the help of internet. This is possible with use of technology.

You must have seen art galleries and attended painting exhibitions in your life. These doesn’t work well these days so artists find a way where they can get more attention and more praise for their work. Most of the artistic stuff is now seen online and is circulated to the art lovers.

There are some places where exhibitions are held and we do respect them. But presenting paintings, sculptures and art work online is in trend. Some of the artists are also showing their art on the basis of card swipe panel or coins.

How this work – when you enter coins or swipe card in the panel, the panel shows you some of the art work for a few minutes and then gets closed and if you want to see it again or explore more, further you need to swipe your card or add coins into it. This is how artists are using technology.

How digital artists are using technology for their art work

Digital artists already in touch with technology are aware of the systems that are in trend and use them to create their art work and sell them online.

Some of the professional digital artists are earning a lot of bucks by selling their art work. They can also design the ones that you want and are also ready to make any modifications you need.

They use different software to explore their skills and made it more impressive. They are using technologies that offer new ways to express their art work in a realistic way for much more time.

They are using different types of media and mix them to provide a more creative art work. Their 3D art work looks as real as it is present live in front of you.

Technology not only brings changes in education, medical field, industry and business but also brings a huge change in the art work and the artists as well.

Technology opens different paths for the artists to enter into for a good earning. They made their profession more powerful along with their art work.

In our busy lives we hardly get time to meet each other and our loved ones. How can it be possible to see exhibitions and galleries? So technology has brought this change in the art workers to show their skills and talent to people from anywhere in the world.

Technology is getting advanced and making more useful for the common man as well as artists. Technology has provided us with several things that we should be thankful. One of them is digital art work.

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.
