Most home computer users don't need an expensive backup solution; as they only need to burn the folders with important documents and pictures to a CD-RW from time to time; this ensuring that in case of a disaster they can easily get them back. Togeder with documents and pictures, it's a critical operation to save the emails, attachments, address book and other important data from within the email client; otherwise in case of a computer problem the user will find himself in the impossibility to get them back, and this can be a really unwanted situation especially for webmasters or people who rely on their emails. Unfortunately many people actually start to do backup copies only after they lose data.
This article will explain how one can create a Outlook Express Backup copy ( as Outlook Express lacks a backup function ) This email program is usually installed with the Windows operating system and is probably among the most commonly used email programs today. While using Outlook Express is fairly easy, finding and backing up the emails can be a little more complicated. Since there are a large number of files and folders on a computer running Windows, the first problem is to find the files containing the emails. Outlook Express stores emails in .dbx files and there might be several different dbx files depending on how many email folders you have created in Outlook Express. If you are using Windows 98, you can probably locate your emails somewhere in the Windows directory. In Windows 2000 and XP, emails are usually stored somewhere in the user data or application data folder.
The easiest way to find out exactly where your emails are stored is to start Outlook Express, go to the Tools menu, and open the Options dialog box. In the Options dialog box, select the Maintenance page and click the Store Folder button. . Here you can find the path to the folder containing your emails. To open the folder, copy the path and paste in the address field of the Windows File Manager.

Email Backup - part 2
You should see a number of .dbx files and possibly some other files, too.
After locating the email folder, you can simply select all the files and press Ctrl-C. Then open the folder where you want to keep the backup copies (on another hard disk, a DVD or a network drive, for example) in Windows Explorer, and press Ctrl-V. To backup the Address Book, you can follow these steps:
a.. Select Tools | Address Book... from the menu in Outlook Express.
b.. Choose File | Export | Other Address Book...from the address book's menu.
c.. Select Text File (Comma Separated Values) as the export format.
d.. Click Export.
e.. Select the location you want to export your address book to using the Browse... button.
f.. Give your backup copy a meaningful name.
g.. Click Next.
h.. Select the fields you want to include in your backup.
i.. Finally, select Finish.
j.. Click OK.
k.. Click Close to end the process (successfully, Ihope).
Additionally, there are several email backup utilities which can make the backup operation much easier. Outlook Express Backup Genie is one piece of software that can offer peace of mind by creating compact backup copies of emails, attachments, address book, signatures, blockedlist, mail rules and settings periodically. The difference between using a automatic email backup utility and manual backups, is that the first can be scheduled to create backups quiet in the background at specified time intervals, and that it will include all email information ( signatures, blocked list, etc ) which otherwise would be more difficult to save. Also if ever the backup is needed, the application will ensure that the restore process is made smoothly. And, it works with top 9 popular email clients.
The downside of using a automatic email backup utility is that it costs money, usually about 20-30 USD as one time payment, while the manual backups are ofcourse, free.The conclusion is that either manual or automatic,backing up emails is a critical operation for every computer user that would regret losing them.

Mambo Content Management System Features
1. The admin interface is confusing. It's all there, just finding and using it is the problem!
2. You need to search around template sites to find ones suited to your site purpose. I wanted simple, clean, business ones. Most of those available seem to have a fat graphic which covers half the screen. There are more restrained ones out there.
These are minor gripes, compared to the relief of finding what is essentially a web site in a box. It can be installed in an hour, once you get familiar with it.

Oscommerce Shopping Cart
this is a full-featured, freeware software. You can add lots of freeware 'plug-ins' to it, to get a professional shopping cart.
Therein lies the danger. Some of these plug-ins require altering or overwriting the default cart files. When you try to upgrade the cart version later, you may 'break' it, by overwriting a plug-in, thus creating errors.
The trick here is to only install plug-ins that add files (rather than overwrite them) or that require minor alterations to existing files.
What I do is download all the versions of the plug-in type I need e.g. a WYSIWYG editor. I then choose the one which has the least files, or which creates a new directory for its files. If it requires that important files be overwritten, or is complex, I chuck it.
Mambo and Oscommerce. Don't try to integrate them! Hyperlink from one to the other. I've tried integrations of other softwares, like PhpBB and PhpNuke. Fine, when it works, but when you upgrade one or the other, arrgh!
*Keep databases separate*. If one goes skew-whiff, then at least the other will still work. Same goes for adding chat rooms and the like. If they're all running off the one database, and that database becomes corrupted ...

Mambo Content Management System
It's freeware. The default set-up allows people without web design skills to update the site. It has a WYSIWYG (What You See Is What You Get) option. This adds HTMLArea code to text input form fields. Each HTML code input box becomes a mini HTML editor.
If you can use Microsoft Word, you can add formatted HTML code to the site.
To get it running you need to know how to install MySQL databases, or have PHPMyAdmin as part of your web-hosting package.
You can add articles, edit them, send emails to members, and be contacted by users.

Data Encryption
Data encryption is the process of coding digital data in such a way that it cannot be read if intercepted by a third party. A user must have a special password in order to gain access to encrypted information.
Encryption is used in a variety of internet communication processes, including VoIP conversations. Encryption is especially important for content that is of a sensitive or private matter, such as in the cases of financial transactions and medical prescriptions.

Electronic-Data-Interchange
Electronic-Data-Interchange, or EDI is a method of computer to computer exchange of various types of information. While many people know of the internet and the World Wide Web as communication methods, the electronic-data-interchange is much similar. It allows the transfer of data from one place to the next with very minimal need for people to get involved.
Today, the Electronic-Data-Interchange is regulated. It offers specific interchange methods that transpire overseas and nationally as standard bodies when it comes to moving information and business transactions from one place to the next. For example, this is the most common form of communication in the process of purchasing goods and services. Communication for the location to the financial institution to deliver a message of the amount of funds required, in this case, is what data will be transferred.
In most cases, the information that is transmitted in an electronic data interchange is done so that companies can communicate. They can provide information to allow business transactions or the passage of very important information. For example, in the healthcare industry they can be used to help communicate through the network about a patient allowing for a faster method of receiving information. This technology is still being developed in many areas, though.
In fact, more and more so, people are turning to Electronic-Data-Interchange as their means of communication especially with more people turning to the Internet. The Electronic-Data-Interchange allows for networks of all sorts to communicate and this is helping ecommerce as a great way for companies to buy, sell or trade information and services. In fact, ANSI has just approved a set of Electronic-Data-Interchange standards. They are known as the X12 standards. Nonetheless, you will see more and more people using them because more and more people are getting online to do just these things.

Data Recovery for Beginners
Right now you probably in a lot of mental pain, and all you’re concerned about is recovering your data as quickly as possible - so we’ll refrain from comments on the wisdom of regular back ups. The time for preventative measures has gone - the issue at hand is data recovery.
First - a simple tip could save you a lot of money. Take out your rolodex and get hold of your tech-savvy friends. If you’re in luck, they’ll offer to help, and if you’re really lucky, they might even have some disk recovery software.
If you’re out of luck, then get out your wallet or purse out now... because this is going to cost you. Also, be prepared for a lot of time being wasted - data recovery can take a long time.
The first thing to establish is what exactly is wrong with your hard disk:
* Either your computer won’t boot up, or
* Your computer boots up OK but you can’t see one of your other drives.
Let’s see if we can eliminate the worst scenario. Listen closely to your hard drive - is it making any sort of weird noise, such as scratching, scraping, ticking etc?
If so, then your drive is physically damaged and the only hope that you have is to take it to a data recovery service where experts might be able to get your data off for you. These services are expensive and time consuming - so you need to make a judgement call as to the value of data on the disk:
If it’s only your saved game data or downloaded music files you would like back, you’re probably better off kicking yourself for not backing up, and accepting the data loss.
If, on the other hand, it’s a book or other type of information product that you’ve been working on for years, then send it to a data recovery service for an evaluation and quote - it usually costs nothing.
If your hard disk sounds OK, then you stand a decent chance of recovering data yourself.
First you’ll need to download some software to help you out.
Unfortunately, the better software utilities are not free, but the good news is that many allow you to try them out to see if they can access the data. There are some freeware products available but generally speaking these are not easy to use - no user interface / little documentation, or they are not very effective.
There’s a list of recommended software on our site - http://www.recoverdatafiles.com - compare the different options then download a few of the trial versions.
Your next steps will be based on how your hard drive/s were setup:
* If you only have a single hard drive that has not been partitioned or split into different “logical” drives, you’ll probably need to attach the hard drive to another computer that has enough space to store all your data. This can be quite technical so if you don’t have the skills please get a computer savvy friend to help out.
Another option is to purchase an external USB hard drive case. You can then simply slot the hard drive into the case and plug it into another PC using a USB port.
* If you have a multiple drive setup and your computer boots up fine, then it will merely be a case of getting the downloaded software to read the files and then copy them to another drive - provided you have a drive with enough space on it. If not, you’ll need to attach the hard drive to another machine with enough spare capacity.
* The scenario where you have a multiple drive setup, where the problem drive is the one that contains your operating system files is more tricky.
Look for a data recovery software package that has a boot disk option available. What this means is that when you start your computer with the boot disk in it, it will automatically run the data recovery program without trying to start windows. You should be able to see your files and then copy them across to another drive.

Oracle Database
There are some very large, very powerful companies out there that have saved quite a bit of money using an Oracle database. Will your company be one of those? Or, will you simply overlook this opportunity? In order to know if in fact an Oracle database will help you, perhaps you have to know a little more about it. Also, you need to realize the differences that are out there in various versions of the Oracle database. Gathering this information will help you make a sound decision about the use of this product in your business.
First, realize that the Oracle database is available to be used and can be benefited from by virtually any size of business. Large corporations, medium sized companies, and even small organizations can all benefit here. What makes it nice to everyone as well is the lower prices that are currently being offered on Oracle database systems. There is no doubt that the introductory price is something to turn heads.

Working of a DSL
A sine wave is a basic type of wave. Sound can be divided into sine
waves.
Sound waves, or sine waves, are measured by the number of cycles they
make in one second.
The number of sine wave cycles sound waves make in one second is
measured in hertz. The symbol for hertz is Hz.
The sine waves created by human voices average 0 to 4,000 Hz. That
means the sound of your voice produces from 0 to 4,000 sine waves made
of sound in a single second. That 0 to 4,000 is considered your
voice's range or frequency.
OK. Now that we've gotten that out of the way:
Telephone wiring is made of copper. That wiring is capable of
transporting much higher frequencies, or more hertz, than just the
frequencies your voice can produce. To put it another way, there's a
lot more room on the wiring that's not being used. So the phone
companies divide up the wiring to use it for other things as well,
namely internet usage.
This may seem like common knowledge. But if you think about it, you
download from the internet more than you upload. You're downloading
this article right now! But how often are you uploading? Maybe you
send lots of emails, which aren't very wieldy, or a big attachment
once in awhile. That's nothing compared to the website and programs
you probably download. So the phone company makes lots room on the
copper wire for frequencies dedicated to downloading from the
internet, and less for uploading. The phone companies uses higher
frequencies on the wiring for both this internet uploading and
downloading.. And by the way, the frequencies are higher than those
used for both voice and faxes. This is how you're able to surf the web
and talk on the computer at the same time!
Have you ever wondered why you need to install filters on all your
phones and fax machines when you install DSL? Well, the filters are to
keep out those higher frequencies reserved for your internet data out
of your phone and fax lines, and keep the frequencies you need to talk
and fax with in.
You can thank your DSL modem for helping the process. Transmission to
and from the internet is all data transmission. The modem is the tool
that sends the data coming to and from your computer over the phone
line to your phone company, while voice or fax signals may be coming
at the same time. At the phone company a contraption called a
multiplexer divides up the voice or fax from the data. Next it sends
the data part to your internet service provider, which takes care of
the rest!

Wi-Fi (Wireless Fidelity)
Wi-fi is a wireless data networking protocol, which allows for PCs and laptops to access the internet, within a given area or "hotspot", via a high frequency wireless local area network (WLAN). The term Wi-Fi was coined by the Wireless Ethernet Compatibility Alliance (WECA) as another name for IEEE 802.11b networking standard. WECA is still involved in certifying new wireless modems in order to verify that they are fully compatible with the standard.
Intuitive algorithm
Roger Penrose considered it impossible. Thinking could never imitate a computer process. He said as much in his book, The Emperor's New Mind. But, a new book, The Intuitive Algorithm, (IA), suggested that intuition was a pattern recognition process. Intuition propelled information through many neural regions like a lightning streak. Data moved from input to output in a reported 20 milliseconds. The mind saw, recognized, interpreted and acted. In the blink of an eye. Myriad processes converted light, sound, touch and smell instantly into your nerve impulses. A dedicated region recognized those impulses as objects and events. The limbic system, another region, interpreted those events to generate emotions. A fourth region responded to those emotions with actions. The mind perceived, identified, evaluated and acted. Intuition got you off the hot stove in a fraction of a second. And it could be using a simple algorithm.
WiMAX
WiMAX is another name for IEEE 802.16, an international standard that allows for computers to be networked together and access the internet wirelessly. Although similar to Wi-Fi, WiMAX has a much broader range, and allows for faster data transfer speeds.
Because of the fact that a single WiMAX base station can cover an entire metropolitan area, it allows for true mobility rather than having to hop from hotspot to hotspot as is necessary with Wi-Fi connections.

Broadband
Broadband is a general term for any technology that transfers data over a broad bandwidth connection. Such a connection allows for much higher transmission speed and quality than its low bandwidth equivalent.
Broadband technology can be used for a variety of different purposes, including high speed internet access (e.g. Cable, DSL, T1, etc.), and VoIP (broadband phone) connections.

REMOTE MONITORING
Remote working or working from home, that is how a layman would call it, is en vogue these days. Most people want to work from the comfort of their homes and save their travel time. Remote working or remote monitoring provides this wonderful opportunity to individuals and business owners alike.
Remote monitoring was designed and formalized by the user community but a major role was played by the Internet Engineering Task Force. Without the help of the Internet Engineering Task Force, this idea could never have been implemented. The proposal for remote monitoring was approved in 1992.
Remote monitoring is a standard monitoring requirement, which provides network administrators with more freedom in selecting network-monitoring probes and consoles. They can choose from many options and pick up the one, which has features that meet their particular networking needs. Remote Monitoring enables geographically distributed network monitors and console systems to exchange network-monitoring data.
The remote monitoring compliant console managers and network probes exchange amongst them, a set of statistics and functions, which are defined in the remote monitoring specification. Network administrators are provided with comprehensive network-fault identification, formulation, and performance-tuning information. Remote monitoring transfers information in nine groups of monitoring contents. Each group provides specific sets of data to meet the requirements of common network-monitoring. It is through the exchange of these data and statistics that the remote monitoring system works.
Remote monitoring has a very big plus point. And that is that all the remote monitoring groups are optional. This means that all the groups are not required to be supported within the Management Information Base (MIB) by a vendor. But some remote monitoring groups may need support of other groups for proper functioning.
Remote working has been made possible by remote monitoring. Remote working has many benefits. It boosts employee productivity. This is so because a person can be 100% productive only if he/she has a relaxed mind. It also helps a person in striking a perfect work-life balance as remote working enables individuals to operate from the comfort of their home. Remote working is also useful for employers as it saves a lot of money in the form of reduced office space, travel time etc.

Companies may have more than one data center as well. Most mid size or higher companies will have at least one data center though. There are many types of data that can be stored in these centers. For example, a financial institution will maintain their clients accounts, numbers and activities in the data center. Businesses will keep client names, accounts, and projects in a data center as well. Because the data a business has is so very important to their existence and their performance, turning to a data center is an excellent option for this type of storage need.
Inside of a data center you are likely to find various types of computers, internet servers as well as many other items. To keep these items safe, data centers are often built and secured physically as well as logistically to protect them. Security is extremely high. They can be one of the safest environments in the city. The main job of a data center is to maintain and run applications to allow businesses to access and manage their files effectively.
There are many information portals now devoted to the subject and we recommend reading about it at one of these. Try googling for “data center info” and you will be surprised by the abundance of information on the subject. Alternatively you may try looking on Yahoo, MSN or even a decent directory site, all are good sources of this information.

Importance of Network Security
Knowing how destructive hackers can be shows you the importance of Network Security. Most networks have firewalls enabled that block hackers and viruses. Having anti-virus software on all computers in a network is a must. In a network, all of the computers are connected, so that if one computer gets a virus, all of the other computers can be adversely affected by this same virus. Any network administrator should have all of the essential files on back up disks. If a file is deleted by a hacker, but you have it on back up, then there is no issue. When files are lost forever, major problems ensue. Network security is an important thing for a business, or a home. Hackers try to make people’s lives difficult, but if you are ready for them, your network will be safe.
Network
In order to fully understand network security, one must first understand what exactly a network is. A network is a group of computers that are connected. Computers can be connected in a variety of ways. Some of these ways include a USB port, phone line connection, Ethernet connection, or a wireless connection. The Internet is basically a network of networks. An Internet Service Provider (ISP) is also a network. When a computer connects to the internet, it joins the ISP’s network which is joined with a variety of other networks, which are joined with even more networks, and so on. These networks all encompass the Internet. The vast amount of computers on the Internet, and the number of ISPs and large networks makes network security a must.
Rackmount
Rack mount computers are essentially computer servers. Computer servers are not the ones you play games on or send emails to your friends with.
Servers perform a small number of specialized operations, some as little as a single operation, but they have the ability to perform it millions of times over and over again, quickly and flawlessly. And when one server is no longer adequate to handle the volume of transactions that a business may require, other, bigger, more powerful servers are needed. When the new servers arrive, they are networked into the system and to save space, are mounted on racks.
When the business with the servers is a steel company, or an automobile manufacturer, industrial rack mount computers are the standard. Stored in rugged steel frames, stackable in standard 19-inch racks, industrial rack mount computers are used for database servers, web servers and networks. Furthermore they are also quite commonly used in laboratory and workshop environments.
Linux is a special operating system that is basically a version of Unix, which has become the foundation of the Internet. When ISP’s like AOL and others came into existence, the amount of servers they needed to accommodate millions of customers eager to surf the web was staggering. In order to make space for that amount of computers, a special rack mounted unit was created to hold the Linux servers. Dubbed the Linux Rack mount Computer system, it became the choice for all of the new Internet businesses all over the world. Soon after, manufacturers of the Linux Rack mount Computer racks where inundated with orders and quickly fell behind schedule.
It took a while for Intel to catch up with it’s rivals, but once they did, the Xeon Rack mount Computers quickly overtook everyone else in the field and became the gold standard among all of the rack mounted computers being installed.

Zone Labs
Windows XP computer users fall into two categories: those who have personal firewall software and those who do not. Knowing that the majority of computer users go without a firewall, Microsoft has included an internet security firewall into the latest XP update called Service Pack 2. If you had no prior firewall, the day you download the SP2 update is a happy day for you.
If you already have a personal firewall such as Zone Labs, McAfee or Norton, then a question arises as to which one you keep, because any computer repair store geek would say you should not keep both the XP firewall or your existing software because it has the dynamic Microsoft name behind it, or go with a more niche company for security such as Zone Labs.

What is Firewall
First, what is a firewall? A personal firewall protects your computer from malicious users by blocking unauthorized access. Who needs a firewall? The term “firewall” gives the impression that only large companies need a “wall” of “fire” to block attacks. You probably feel your computer is too small to attract an attack. But let’s not forget that hackers are hackers because they are students of behavior! They know that millions of people think they’re not targets and forego internet security. They build viruses to seek out such vulnerable computers, which can lead to a multitude of computer problems, not to mention identify theft.
Perhaps if firewalls were renamed, “personal identity insurance,” more people would realize the need to own it! So, does the Windows firewall do the job? While it will block incoming attacks, it will not block programs already installed on your computer from sending information out.
Many downloads you agree to will have spyware attached, and spyware often “phones home” with information about the user. Windows XP firewall will not stop this which is why computer experts suggest that for maximum protection you should go with a full firewall protection like the ones offered by Zone Labs, Norton and McAfee in lieu of XP’s.

Basic Computer Terminology
Cache: Cache is another type of memory kindred to RAM. The computer uses cache to quickly move data between the RAM and the CPU.
CD-ROM Drive: Most new computers now come with a CD-ROM drive as standard equipment. A CD-ROM drive reads data from a disc. These CDs look like a music CD, but hold data instead of music. CD-ROMs also contain games, dictionaries, recipe files, and lots of other things that you can load onto your computer.
CPU: The CPU, or central processing unit, is the brains of the computer. Most new Windows based programs use a Pentium processor or a AMD Athlon XP. New Macs use a different type of CPU called Power PC.
Disk Drive:Virtually all computers come with a disk drive that can read and save information on portable diskettes, also called floppy disks. You can use floppy disks to save information or to load new software onto your computer.
Hard Drive: The hard drive is also called the hard disk. You'll probably never see it because it is nestled inside your computer. It's the computer's electronic filling cabinet, and it stores the computer's operating system, files, programs and documents.
Keyboard: Just like a typewriter keyboard, this device is the primary way of inputting data into the computer programs.
Megahertz (MHz): This is the clock speed of the microprocessor. The higher the number, the quicker the information is processed. MHz relates to how many millions of instructions can be processed per second.
Memory:This is the circuitry or device that holds information in an electrical or magnetic form. There is read-only memory (ROM), which is information primarily stored on a disk, and random-access memory (RAM), which is chip-based storage inside the computer. Memory is typically measured in megabytes (MBs).
Modem:This mechanism connects a computer to a phone line so information can be sent from one computer to another or the user can access an on-line service or the Internet. In view of the popularity of the Internet, a modem is now considered basic equipment and comes on practically all-new computers. Most modems come with fax capabilities.
Monitor: An output device that allows you to see what you are doing (it is what you are looking into right now to see this). Most computers come with 14 or 15-inch monitors. This size is good for most people's needs. Larger 17 or 21-inch monitors also are available, but may cost more. Myself, I prefer the 17-inch.
Motherboard:The motherboard is the circuit board that everything in the computer plugs into. The CPU, RAM and cache all plug into the motherboard.
Mouse: The mouse is another input device that makes getting around in your computer easier. It is a handheld object that is good for doing tasks such as moving and pointing to objects on the screen, and can replace the function and control keys of the keyboard. (If you need a lesson on how the mouse works and how to use it click here for a tutorial.)
Printer: A printer is an essential part of the computer if you want a hard copy of your work. There are four types of printers on the market: dot matrix, inkjet, bubble jet and laser. The dot matrix is the most basic. Most inkjets and bubble jets can print color and graphics, and a laser printer offers the best resolution at the highest speed.
RAM:Computers save data in two ways: on the hard drive and in random access memory or internal memory. New computer buyers should look for models with at least 16 MBs of RAM (or more, depending on what types of programs you'll be running). Make sure that the computer can be upgraded.
Scanner:A scanner is a useful accessory to have if you are working with lots of artwork or photos. This device can copy written documents, pictures or photographs directly into your computer. There are three types of scanners: handheld, hopper-feed and flatbed.
Sound Card: This device allows your computer to reproduce music, sounds and voices. Make sure you have a sound card if you're planning to play multimedia games.
Video Card: The video card is the part of the computer that sends the images to the monitor.

COMPUTER BACKUPS
Computer backup is so important to your computer that to ignore it is to risk its damnation.
Computers require care and feeding. They require that you attend to their needs. If you don't, then they will most surely be sent to Hell.
Halloween means Hell. What! What do you mean that Halloween means Hell?
Well, if your computer is given the option of trick or treat, which will it accept? Will it accept the trick or the treat? What do you think?
Halloween is the time that computers are subject to tricks or treats. Did you know that more computers fail on Halloween than any other day of the year? That’s right. It’s true (smile). Your computer is in danger! Protect it. Do your computer backups.
Back to the Hell thing. Hell you say? Yep. Well, what do you mean by Hell?
Computer hell is the place for computers without computer backup. The failure to perform hard drive backup means that you are playing Russian Roulette with your data. Data needs your protection. Failure to protect your data may cause your home or business records to be sent to Hell.
Hell in this instance is for the records and files that cannot be resurrected. Resurrected you say, what does that mean?
It means that without computer backup as a source of salvation then the files can safely enjoy eternal oblivion. Oblivion you say, what does that mean? That means they are eternally lost from computer resurrection.
Is there any mercy for my precious files, you ask?
Why yes there is. Would like to know what the mercy for your files is? Yes! Yes! You say.
OK boys and girls listen carefully. The salvation, mercy, resurrection and redemption of your files lies in regular and consistent and persistent computer backup.
If you backup your computer consistently and persistently your files will be resurrected and saved from accidental deletion, hard drive failure and those nasty things like fire, flood, theft, earthquake, hurricanes, tornados and the like!
Computer backup is the key to your data's salvation!
Do your computer backups boys and girls.
Milk and cookies will be served in the pantry.
