PHP and MySQL training is very popular with programmers who are keeping up with changing times. Recently emerged programming languages PHP and MySQL are side server web applications that allow the user to write data base, based web pages. MySQL has proven to be very effective and when it is combined with PHP, eve more so.
This combination of technologies provides the programming student with very necessary skills to build complex web pages which depend upon a database system to function successfully. The fundamental knowledge for learning PHP and MySQL is HTML. PHP and courses are structured such that the student practices the programming language for seventy percent of the training period. This is normally carried out by applying the languages to real life scenarios. By so doing, the students acquire hands on practical application of both these languages.
The main objective of this training is to enable the student to work with the fundamentals of interactive, multi-functional websites which operate from databases and they are required to learn about forms, PHP email handling, strings, integers, file handling, HTML/CSS, handling sessions, and email in PHP.
As this training is conducted online, you computer setup also have to have certain basic requirements. These are Linux and Window, Macos X of Solaris operating systems. A we server of sorts, Microsoft IIS or apache will work, Internet Explorer, Firefox and various other applications. You should find out what these requirements are, applicable to the training you are undertaking and make obtaining them a priority before staring your course.
PHP is written to operate the front end of the website while MySQL is written for the database on which the website operates. These two languages are integrated and Basic HTML knowledge is a prerequisite for learning these. Students are taught the fundamentals of building websites as well as databases.
As with most things it is important to practice in order to understand properly and become adept at what you are doing. The same applies to PHP and MySQL training. Every day problems and solutions are used in the training course, which enables the student to learn the rudiments of creating an interactive website.
In the changing times we live in, MySQL and PHP training is essential for any person who wants to continue with a career in IT. Technology moves very fast and unfortunately anyone with an IT career, is going to have to regularly become a student again as programming languages and systems change.
These days, many workplaces couldn't function properly without the help of support workers fixing both computers and networks, while advising users on a day to day basis. The desire for such skilled and qualified members of the workforce is constantly growing, as everywhere we work becomes more and more technologically advanced. Seeing as the computer market provides some outstanding career possibilities for everyone - what questions do we need to be posing and what elements carry the most importance?
Don't get hung-up, as can often be the case, on the certification itself. Training is not an end in itself; this is about employment. Begin and continue with the end in mind. It's a sad fact, but a large percentage of students commence training that sounds great in the prospectus, but which provide the end-result of a job which doesn't satisfy. Speak to a selection of college graduates and you'll see where we're coming from. Stay tuned-in to what you want to achieve, and build your study action-plan from that - avoid getting them back-to-front. Stay focused on the end-goal and ensure that you're training for something you'll enjoy for years to come. It's worth seeking guidance from someone that understands the market you think may suit you, and is able to give you 'A day in the life of' type of explanation for each job considered. All of these things are essential because you obviously have to know if this change is right for you.
You should only consider learning programmers that move onto industry approved qualifications. There are far too many trainers promoting unknown 'in-house' certificates that are essentially useless when you start your job-search. From an employer's viewpoint, only top businesses such as Microsoft, Adobe, CompTIA or Cisco (as an example) provide enough commercial weight. Anything less won't make the grade.
We'd hazard a guess that you probably enjoy fairly practical work - a 'hands-on' type. If you're like us, the unfortunate chore of reading reference guides can be just about bared when essential, but it's not ideal. Consider interactive, multimedia study if books just don't do it for you. Our ability to remember is increased with an involvement of all our senses - this has been an accepted fact in expert circles for decades now. Start a study-program in which you'll receive a selection of CD and DVD based materials - you'll learn by watching video tutorials and demonstrations, with the facility to practice your skills in interactive lab's. You must see the type of training provided by each company you're contemplating. Be sure that they contain instructor-led video demonstrations with virtual practice-lab's. Pick disc based course ware (On CD or DVD) if possible. You're then protected from internet connection failure and issues with signal quality.
If you forget everything else - then just remember this: It's essential to obtain proper 24x7 round-the-clock instructor and mentor support. You'll definitely experience problems if you let this one slide. Look for training with proper support available at all hours of the day and night (no matter if it's in the middle of the night on a weekend!) Make sure it's always direct access to tutors and not a message system as this will slow you down - waiting for tutors to call you back at a convenient time for them. The very best training providers have many support offices from around the world. They use an online interactive interface to provide a seamless experience; any time of the day or night - help is just a click away with no hassle or contact issues. If you accept anything less than 24x7 support, you'll regret it very quickly. It may be that you don't use it during late nights, but you're bound to use weekends, early mornings or even late evenings at some point?
Consider the points below very carefully if you think the sales ploy of examination guarantees seems like a good idea: Everyone knows they're ultimately paying for it - it's not so hard to see that it's already been included in the overall figure from the course provider. Certainly, it's not a freebie - don't think these companies are so generous with their money! Students who go in for their examinations when it's appropriate, paying for them just before taking them are in a much stronger position to qualify at the first attempt. They are thoughtful of what they've paid and prepare more appropriately to be ready for the task. Don't you think it's more sensible to go for the best offer when you're ready, not to pay any mark-up to a training course provider, and to take it closer to home - instead of the remote center that's convenient only to the trainer? A surprising number of questionable training companies secure a great deal of profit through charging for exams at the start of the course then cashing in if they're not all taken. The majority of companies will require you to sit pre-tests and with-hold subsequent exam entries from you until you have proved to them you have a good chance of passing - making an 'exam guarantee' just about worthless. Exams taken at local centers are approximately 112 pounds in Great Britain. Why spend so much more on 'Exam Guarantee' costs (often covertly rolled into the cost of the course) - when good quality study materials, the proper support and commitment, effort and practice with quality exam preparation systems are the factors that really get you through.
We're regularly asked to explain why academic qualifications are being overtaken by more commercially accredited qualifications? As we require increasingly more effective technological know-how, industry has moved to the specialized core-skills learning only available through the vendors themselves - for example companies like CISCO, Adobe, Microsoft and CompTIA. This frequently provides reductions in both cost and time. Of course, a reasonable amount of relevant additional information must be learned, but essential specialized knowledge in the areas needed gives a commercially educated student a distinct advantage. It's rather like the advert: 'It does what it says on the tin'. The company just needs to know what they need doing and then match up the appropriate exam numbers as a requirement. They'll know then that all applicants can do what they need.
The world of information technology is one of the more thrilling and changing industries that you can get into right now. Being a member of a team working on breakthroughs in technology means you're a part of the huge progress affecting everyone who lives in the 21st century. We're barely beginning to get a handle on what this change will mean to us. The way we communicate and interact with everyone around us will be massively affected by computers and the internet. The standard IT worker in the UK can demonstrate that they earn significantly more than employees on a par outside of IT. Mean average wages are around the top of national league tables. Apparently there is no end in sight for IT industry expansion across Britain. The industry continues to grow rapidly, and as we have a skills gap that means we only typically have three IT workers for every four jobs it's most unlikely that things will be any different for years to come.
Hackers and scammers come up with creative ways to gain control of you and your computer. Unfortunately for us, it’s sometimes very hard to figure out when you are about to be scammed. It’s very important that we know the signs when someone is about to take advantage of us and our computers. Listed below are common scams and tactics that people will use that will then lead to a malicious attack.
1. Phishing Emails
Phishing attempts usually come by form of email. Scammers will send you an email that looks like it has come from a legitimate site, like banks or from stores that you often shop at. Some of the most common forms of a phishing attack include:
Emails from people claiming to be stranded somewhere. In this type of email, they will ask you to send them money by clicking on an attachment they have sent you. Once you click on the link, the scammers will have access to your private information.
Emails claiming to be from news organizations talking about some of the biggest news in the world at the time. These emails will ask people to click on the link given so they can then read the whole story. That link will then lead you to a malicious website. This is where the scammers can gain access to your computer's information.
Emails threatening to harm you or someone you know if you do not pay the sum of money they are requesting.
2. The Money Laundering Scam
This is one of the oldest scams around. Nearly everyone at one time or another has gotten an email from someone begging you to help them to retrieve their large sum of money from a bank. In exchange for your help, they will offer you a large amount of money.
This is all only the beginning, though, because soon they will be asking you for more money for additional services. At the end of this, you will be left broke and without the promised money. There have even been cases where these people have made a malicious attack on the computer.
3. Greeting Card Scam
This email always looks like it is coming from a friend. However, when you open it, you aren’t surprised with something sweet; you’re surprised by scammers gaining control of your computer. After the “card” is opened, malicious software is downloaded, which is when pop-ups will start showing up all over your screen. You may also notice strange windows popping up on your screen once your computer has been attacked.
There are some very destructive and creative ways for people to gain control of you and your computer. It is often very hard to decipher when you are being attacked. You should always be on the lookout when you get emails. Scammers are always lurking and are just waiting for you to let your guard down so they can take what is rightfully yours. But when you’re always aware, you will be able to prevent yourself from being scammed.
It is normal to see pop-up ads while surfing the net, right? What a lot of people don’t realize is that those ads could have made their way onto their computers through spyware. By the time that you figure out what is behind the ads, the spyware pop-ups may have gotten so bad that your only choice is to completely reconfigure your computer and just hope that the pop-ups don’t come back. And, if your only mechanism to fight against the spyware is hope, the pop-up ads will return.
What is Spyware Exactly?
Spyware is a type of software which gets onto your computer and is generally used to gather your personal information and then send advertisements to you, normally in the form of a pop-up ad. Spyware software can also change your computer configuration as well as many other potentially harmful things. Even though the term spyware may suggest that the software is simply monitoring action in a secretive way, the purpose of spyware usually goes well beyond this.
The party responsible for creating and distributing the spyware are often profiting greatly through targeted advertising or selling off your personal information.When spyware software is on a computer, it generally is hidden from the user. In 2005, a study carried out by AOL and the National Cyber-Security Alliance showed that 61% of user’s computers were infected with spyware. Of all of these users, 92% of them were not aware that their computers were even infected. 91% of the users claimed that they had not granted permission for the spyware software to be installed.
Since then, spyware has become increasingly sophisticated and is often impossible to detect on a user’s computer. Even worse, once detected, some spyware is impossible to remove.
Difference between Spyware and Adware
The terms spyware and adware are often used interchangeably. Both of these terms are used to describe software which can display advertisements. However, there is one major difference between these two: spyware gets onto the user’s computer through illicit means.
With adware, the user agrees to have the adware program installed in exchange for something else.
For example, the program Eudora will allow users access to shareware for free but they must agree to receive advertisements.The key word here is “agree.” Adware will not attempt to mislead users and is offered in exchange for a service. An example of adware includes the file sharing program Eudora. Rather than asking users to pay a registration fee, it asks them to agree to receive advertisements.
On the other hand, Gator software is a type of spyware. When users visit certain websites, spyware is installed on the users’ computer through some sort of deceptive manner. The company behind Gator as well as the website where the spyware was installed will both receive revenue.
Today, there are an incalculable number of “health” problems that a computer can be at risk for. Generally, these risks can be broken down into spyware, viruses and worms. It is easy to confuse these different types of computer problems because they have many similarities.
Spyware, viruses and worms all get onto a user’s computer with permission or by using deceptive means. Once on the computer, they cause harm to the computer and impair functions.
Spyware, viruses and worms are all designed to be difficult, if not impossible, to detect. They often are designed in a certain way that prohibits them from being removed in normal manners. Recently, there have been many viruses and worms which have been, as spyware is, created for profit. Compared to viruses and worms, spyware is a relatively new problem.
Viruses have been around since the 1980s and worms almost as long. Spyware didn’t become a major issue until 2000. The major difference between spyware and viruses and worms is that spyware doesn’t seek to replicate once on your computer. It also doesn’t seek to infect other computers Both viruses and worms, on the other hand, actively replicate themselves and can spread to other computers through means such as email.
Another big difference between spyware, viruses and worms is objective. Spyware is always used for some form of monetary gain such as through advertisements. Modern viruses and worms can also be used for monetary gain. However, viruses and worms are often created in an attempt to gain fame. Some virus and worm creators have claimed their motivation was to show how far virus creation has advanced. Other creators desire to “outdo” the creators of anti-virus and anti-worm software. As in the case with the Bagel and Net sky viruses, the creators of the viruses wanted to outdo each other.
Additionally, viruses and worms are often created specifically to do damage to a computer through a type of web espionage. An example of this is the Conflicker worm which spread in 2008. It made its way into the defense systems of France and Britain as well as about 15 million computers around the world and creating severe damage to the computers’ health. Spyware, however, does not want to cause severe damage to the computer. That is because it relies on the computer’s health in order to send advertisements to users.
Is there a Spy-Vir-Orm Hybrid?
It is getting increasingly difficult to distinguish between spyware, viruses and worms. As all three of these computer health issues become increasingly sophisticated, they have taken on properties of one another and often rely upon one another for functioning.
There are many instances when spyware is spread through a virus or visa versa. There are also many instances of spyware, worms or viruses creating openings for other types of harm to enter a user’s computer. Because of this crossover between the spyware, viruses and worms, it is important that countermeasures are taken against all forms of computer infections.
In most cases, spyware gets onto your computer because you have installed it unknowingly. This is how it works: when you find some sort of free program or file online, you download it and it comes bundled together with spyware. This is also the case with shareware. For spyware creators like Claria, which is the largest spyware company, this method of spyware transmission is very profitable. Claria had revenues of $35 million just last year.
Spyware as a profitable business really began to surge when free internet applications became available online. Since applications such as Web browser, email, and instant messaging were free, it didn’t take long before users expected free software as well. Software makers were having a hard time selling software for even low prices and they had trouble battling against illegal file sharing as well. Instead of trying to increase sales, the software makers decided to offer free software but include spyware bundled with it.
A spyware company will pay a software company for every time the software is installed. Then, the spyware uses targeted ads on the user. When a user clicks on the ad or makes a purchase through the ad, the spyware company profits. An example of this is the free file sharing application Kazaa which comes bundled with spyware from the company Claria. Kazaa gets paid by Claria every time its program is installed.
Then, the Claria spyware creates targeted pop-up ads for users and profits each time one of those ads is clicked on. If you visit the Dish Network homepage, a pop-up ad for DirecTV will appear. This method of spyware distribution occurs with all sorts of free downloads including software and file sharing. Often, the terms and conditions for downloading a free application will mention that spyware is included with the download.
However, not many people take the time to read through the terms and conditions. It is also common for the information about spyware to be deceptively hidden in a very long and confusing terms and conditions statement. The downloader simply clicks “Accept” and gets the spyware.
Fake Windows Security Boxes
To start downloading spyware, sometimes all it takes is a click of a link. One of the most common ways that spyware makers get users to click on their links is by disguising them as Windows security boxes. The boxes look just like a normal Windows security box. However, when you click on them, the link causes your security settings to change and spyware to be installed on your computer without your knowledge. For example, a box might read, “Optimize your internet access.” Even if you hit the “No” button, you will still trigger the spyware.
If you do not have high security on your computer, you run the risk of spyware finding its way inside. Some of the newer spyware programs have even learned to find their way through holes in firewall and antispyware software. Spyware is often distributed with a virus. First, a virus is sent to a computer. Instead of replicating and possibly destroying a computer’s system like a normal virus, its job is instead to create a hole for the spyware to enter.
There are several other illicit ways in which spyware can enter a computer. For example, there are spyware programs which are spread through emails. Even if the email gets tagged as potentially dangerous and the user doesn’t read it, the spyware can still be spread just by having it displayed in a preview pane.
Because there are so many different ways for spyware to enter a computer, it is almost impossible to avoid infection. Avoiding certain activities, such as downloading, can reduce the risk but there are still many ways for spyware to enter. That is why preventative and real-time counteractive measures need to be taken.
The first step to preventing spyware infections (and re-infections after spyware is removed) is to educate yourself. By understanding why spyware exists, you can start to identify possible threats while you are online. So, if you skipped the first five chapters of this eBook, now would be a good time to go back and read them before continuing on.
Research Before You Download
Even though downloading any sort of free file or software is one of the biggest risks when it comes to getting spyware or other computer infections, most people are not going to stop downloading. There are simply too many desirable free programs and files out there. However, you can greatly reduce the risk of an infection by researching the freebie first.
Whenever downloading free software, type its name into a reputable search engine along with the word spyware. Chances are, if that program comes bundled with spyware, you won’t be the first to get it. If you type in “Kazaa spyware” into Google, for example, the first several pages of results all mention the infamous spyware as well as how to remove it.
Change Your Settings
Some of the preventative steps against spyware are very simple to take. For example, you can use Mozilla Firefox instead of Microsoft’s browsers which have several security holes which are easy for spyware programs to enter through. Also, switching to a Mac or Linux operating system will greatly reduce your risk of various computer infections because most are targeted at Windows. However, this is not such an easy change to make.If working on Windows Explorer, you will want to install Windows XP Service Pack 2.
This service pack solves many of the security holes in Internet Explorer and it also has a built-in pop-up blocker. There are also features like the add-on manager which will allow you monitor which programs are running with Internet Explorer.You will also want to change your Security Zone settings on Internet Explorer to block harmful sites. The settings have the options of listing sites as Trusted, Restricted, Local Internet, or Internet.
If you list a site as restricted, you are still able to visit that site but the security settings will prevent the site from harming your computer. Some antispyware tools like Spyware Blaster and Spybot Search and Destroy will add automatically add harmful sites to the restricted setting. If your computer internet is connected to a dial-up modem, you will want to unplug the modem when you aren’t using it. This will prevent spyware from committing dial fraud by calling premium numbers.
One of the reasons that spyware is spread so quickly is because of all the free downloads which have spyware software bundled in with them. Obviously, many people are not willing to pay for software- especially antispyware software. Luckily, there is now a lot of free antispyware software available.
One of the ways to get free antispyware software is simply to download it from the internet. However, it is very common that the free antispyware software actually comes with spyware bundled in with it. You can read the next chapter to find out about this risk. Here is a list of some of the best antispyware software programs available for free online.
Free Spyware Protection
Windows Defender: Before any software can be installed, it has to pass a Windows Genuine Advantage test. This antispyware software works in real time. It takes up little running space and can be put on a schedule for scanning a computer system. However, it is not the best choice of software for stopping all spyware.
Spybot Search & Destroy: This is one of the most well-known antispyware software programs. It has been around since 2000 and is regularly updated. It has an immunization feature which will add malicious sites to your Restricted Sites list to protect you in case your computer is hijacked and taken to a harmful site.
Ad-Aware: Ad-Aware is another one of the most popular free antispyware software. It can be downloaded for free. However, there is also a commercial version of Ad-Aware which offers even higher levels of protection. It also includes antivirus.
AVG Anti-Spyware Free Edition: AVG is popular became popular as antivirus software and now has created antispyware software as well. There is a commercial and a free version available. AVG is one of strongest in terms of overall computer protection. However, like all free antispyware software, it does not contain a built-in firewall.
Avast! antivirus Home Edition: This software is a combination of antivirus, antispyware and anti-rootkit. It is made for Windows and is free for home use.
Panda Cloud Antivirus: This program also includes antispyware.
Microsoft Malicious Software Removal Tool: Called MSRT for shot, this software is available for free so long as your Windows is genuine. There are free monthly updates of MSRT available for users on the first Tuesday of each month.
Comodo Internet Security: The Comodo company makes several software programs including antispyware, antivirus, and a firewall. You can download each of these separately for maximum protection. There is also a paid version called Comodo Internet Security Pro. Comodo is one of the strongest when it comes to battling computer infections. However, the software may be a bit difficult for beginners to operate and the free version doesn’t have any customer support.
Spyware Blaster: This software does not remove spyware infections. Its goal is to prevent spyware infection and has a list of thousands of malicious sites which can be added to your Restricted Sites list. It also has a feature which will allow you to lock your Internet Explorer homepage so it can’t be altered.
Free Spyware Removal Tools
SuperAntiSpyware: If you already have a spyware infection, this software has been reported as effective in removing the spyware.
HijackThis: This freeware utility works a bit differently than most spyware removal tools because it doesn’t just perform a simple scan based on a list of spyware. Instead, it scans the computer and looks for all suspicious items. Then, HijackThis will ask the user what to do with those items. Users should be very careful while using HijackThis to not delete any useful or essential items.
Removal Restrictions Tool: Also known as RRT, this tool is used to restore permissions in situations where spyware has locked users from the Control Panel, Task Manager or Regedit.
There are a lot more free antispyware programs available with new ones constantly becoming available. However, it is important to note that many of these are not completely effective in preventing or removing spyware. Usually, they each have a few loopholes which spyware makers are aware of and exploit.
One way to get around the loopholes is to use multiple free antispyware software programs at once. What one program misses will generally be picked up by another program. The only real downside to this method is that using multiple antispyware programs can make your computer run slower.
Also, it needs to be pointed out that many of the free antispyware which is advertised online is actually rogue antispyware. This software actually contains spyware which will infect your computer.
There are a lot of antispyware software programs out there and all of them offer different levels of security. Before you antispyware software, you should at least take a few minutes to do some research and find out more about the software. You can easily get lists of the “best” antispyware software from blogs and websites. Then, use these lists for further investigation.
Here is what you should be finding out about the antispyware before downloading:
Who makes the antispyware: There are a lot of well-known companies which make antispyware, such as Microsoft. However, this doesn’t mean that the big brand names are offering the best products. What is important is that the company has a good reputation for antispyware software. Some of the best companies have been around for a long time. Since they have been dealing with spyware issues for so long, they may be adept at fighting against the threat.
Are there any complaints about the company: Generally, you can easily uncover any complaints about an antispyware company simply by typing its name into a search engine. You may also want to try searching for the company’s name followed by “complaints.” If there are more negative comments than positive ones, you can be sure that there are major issues with that software program. To really be sure about the company’s reputation, you can visit the website for the Better Business Bureau. There, you will find out if there are any unresolved complaints against the company.
How are its reviews: There are countless blogs and other websites which have reviews of antispyware software. Some of these are left by users while others are by professionals in the field. To make sure that the reviews are accurate, you might want to check out reviews at sites like www.shoppingfortoday.com/software which carries software.
Keep in mind that there is no one best antispyware software program. Rather, it matters which antispyware is best suited for your needs. Here are some other factors you should take into consideration:
How easy is the antispyware to use?
Does the antispyware come with customer support?
Will the antispyware slow down your computer?
Is the antispyware effective in prevention?
Is there real time prevention?
How effective is the software in spyware removal?
Do you need to update and, if so, are updates free?
What scanning options are there?
Does the antispyware include antivirus as well?
How much does the antispyware cost?
Almost all antispyware software today comes with a free trial period. It is highly recommended that you take advantage of this option in order to see how you like the antispyware before you decide to buy it.
