Protecting Children Online Steps Toward Making Your Computer “Weirdo-Proof”
It’s an unfortunate fact of reality, but children are the most victimized computer users on the Internet today. The good news is that there are some practical steps you can take to protect your children from sexual predators, hackers, and other seedy individuals who want to cause harm. This article will describe a few of them.
The first step in protecting your children at the computer is to prevent their access to passwords. This will keep them from sharing passwords with others and inadvertently enabling hacking into your system. If you think about it, there’s no reason why a five, seven, or even twelve year old needs to know the passwords to sensitive areas on the computer unless you’ve given them permission! In fact, children don’t need to know the password used to access the Internet either. It may be a hassle to type it in each time they want to get online, but it’s better to know the times that they connect than to have them sneak online without your permission and knowledge of their activities.
The second step towards protecting your children online is using the computer together. Siting next to your child while he or she peruses the Internet, you can guide him or her to make safe and intelligent decisions. You can approve websites and bookmark them together. You can monitor the conversations your children have with their friends and teach them appropriate online behavior at the same time. You can make recommendations and create a private time for quality time as well.
The third step involves blocking access to inappropriate areas altogether. You and your children may not always agree about what’s appropriate, but as a guardian, you’re in control and you’re ultimately responsible for their safety. Take the time to investigate software tools that put you in control and allow you to block access to certain websites. If you use an online service like AOL (America Online), you can use its internal Parental Control settings to block access to various chatrooms and websites. You could even block instant messaging and email from anyone who isn’t a fellow AOL user.
Other tools available online operate similar to the way that AOL’s Parental Control settings work, however no collection of tools could replace the reinforcement of mom and dad. Never let your children speak with strangers and never leave them alone at the computer unattended. Children just don’t have the experience that adults have and they don’t have the skills required to handle inappropriate conversations, emails, or images found online.
NOTE: Some of these tools include kid-specific web browsers that will visit pre-approved websites. Others include browser plug-ins that won’t allow access to online areas that contain forbidden keywords.
Another step requires teaching your children to never ever volunteer personal information. Under no circumstances, should children give their personal names, home addresses, phone numbers, or school information to anyone over the Internet regardless of the situation. In the even this information is required to enter a contest of some sort, be sure that you’re the one who makes the decision to supply it and that you’re the one who does it.
Performing all of these steps won’t be easy. However you can help minimize resistance to your monitoring efforts by explaining why you’re taking these precautions. Smaller children will probably enjoy the time you spend together at the computer, but older children and pre-teens may resent it. To help build a case for your concern, you might want to show your older children a few news stories that exemplify the dangers that unsupervised children are exposed to. The newspaper is unfortunately full of examples but with your help, we can reduce them world-wide.
Using Computers It’s Not Rocket Science
These days it’s strange to hear people say, “I’m just not computer literate,” as computers have evolved from archaic scientific calculators to simple point-and-click type machines. We suspect that today’s “computer illiterates” are people who haven’t taken the time to experiment with such a machine. And we strongly believe that spending just twenty minutes with one could turn the most adamant technological caveman into any one of those who have fun wreaking chatroom havoc on the Internet today.
Today, one only needs to learn how to manipulate a mouse, punch a few buttons on a keyboard, or really just turn the thing on to use a computer. It’s hard for some folks to believe, but the computers of this generation almost run themselves! For fun, let’s investigate just how little knowledge these thousand-dollar machines actually require.
Can an absolute newbie operate a computer without knowing how to use a mouse or keyboard? Assuming that a computer is set up to operate on voice command – sure! Voice command software allows users to tell a computer what to do and the computer responds by fulfilling the user’s commands. Although it’s pretty new and still under development, voice directed technology has already infiltrated consumer service related systems.
Think back to the last time that you paid a bill over the phone. Instead of speaking to a human being, chances are that you spoke to a computer that not only responded to what you said and followed the commands that you gave it, it also asked you for more information such as your full name or credit card number. In this case, a person (such as yourself) operated a computer without even knowing it!
Can an absolute newbie sit down at a computer without knowing how to use one? Assuming that a computer is set up to operate on touch command – the answer is again, yes! Touch command software allows users to literally touch objects on a monitor and tell the computer what to do with a finger. Known as “kiosks,” these programs are already in use world wide at ATM machines, employment centers, and in health monitoring systems.
Neither a mouse nor a keyboard is required. A computer user only needs to touch various boxes on a screen to control a computer. Sure, the programming behind such technology is extensive and advanced, but to the end user, it makes computer use less intimidating and plain easy.
Of course when we talk about operating a computer, we envision more involvement than speaking on the phone or touching things on a screen. The above illustrations were just a couple of examples of how far computer technology has grown, and how far we’ve pushed “user-friendliness” to its limit. Eventually, the keyboard and mouse will have to play a role when computer newbies have to work with one as a cash register, as a hotel booking program, or as a library’s catalog system.
These requirements don’t make computers any less easier to operate, but they don’t make them that much harder either. So much of today’s software is designed to accommodate the experience of a new user that anyone could get connected to the Internet, send an email message, and download an MP3 file within the first five hours of purchasing a personal PC.
Automating Things with Batch Files They Work on Today’s Computers Too!
If you’re familiar with MS-DOS at all, you’ll recall that it’s a command-driven operating system that performs functions issued at the C:> prompt. The only way to get an MS-DOS computer to do something was to type a command at this prompt and if you can imagine, it was a rather cumbersome way to use a computer.
As an example, to load up Microsoft’s simple editing program, you had to type the name of the drive that the program was on, the directory that the program was in, and then the name of the program. So if Microsoft Edit was in a directory or folder named “Process,” you could start the program by typing, “C:>process\edit.com” Then, and only then would the program load up for use.
This is a small command, but just imagine if you had a program that was deeply nested within a series of folder. You could end up typing a command as wide as your computer screen or worse, long enough that the entire command would have to wrap onto the next line! Now imagine having to type these long commands every time that you wanted to start a program. Yikes!
That’s one of the reasons why batch files became so popular. Batch files are small text-based documents that contain a bunch of these commands on their own lines. When executed, they would process each command without the user having to type each and every one of them.
When Windows was developed, the need for typing commands was essentially eradicated thanks to the introduction of the point-and-click (mouse) interface. But this didn’t stop the batch file fever that started under MS-DOS – and in some small circles, batch files are still as popular as they were in the beginning.
Even though you may use Windows XP or Vista, batch files can save you tons of time by automatically starting multiple programs and performing different tasks at the single click of a button. They don’t require any extensive programming background and they don’t need to be encrypted with some weird, expensive compiler. Batch files are plain text files, and you can build one for your own personal use with Windows’ Notepad.
You could make a batch file that loads up your favorite websites at once for example, or you could make a batch file that fills your desktop with the most important applications for the day. To do so only requires a little knowledge about the locations of these applications.
Let’s say that every day we need to load up the Yahoo web browser, Microsoft Word, and then the calculator that comes with Windows. Instead of doing this by hand, we could write a batch file to do it for us.
First, we’d load up Notepad and type in the following:
START “http://www.yahoo.com”
START “c:/program files/microsoft office/office/winword.exe”
START “c:/windows/calc.exe”
We would then save this data into a file named, “mytasks.bat” onto the Desktop for easy access. Each time we double-clicked on this file, the Yahoo website would load up, Microsoft Word would start, and the simple calculator would pop up.
Since we want these programs to load every day, we could create a shortcut to this file and then place the shortcut inside our computer’s Start Up folder. That way, these three programs would load every time we turn on the computer. If you wanted these programs to start minimized, you could type the following into a batch file instead:
START http://www.yahoo.com /m
START “c:/program files/microsoft office/office/winword.exe” /m
START “c:/windows/calc.exe” /m
This will run all three programs as before, however the “/m” parameter will minimize them so that they don’t clutter up the desktop.
Other people have found much more creative and effective ways to use batch files, but the important thing is that you know they’re a resource you can use to save a few seconds or minutes in performing important tasks. We’ve come a long way from MS-DOS, but it’s still a valuable source of automation that anyone can use with no programming knowledge at all.
