How to Convert Fat-32 to NTFS


These are file systems for disc partitions that are present in computers running on Windows XP. NTFS, short for NT File System has been recommended by Microsoft itself, and is said to be the more powerful of the two file systems. It includes some features like the use of B-tree Directory to keep track of file clusters, and the fact that it can support very-large files. Its security measures are also an improvement on earlier file systems. FAT-32 is an earlier version of the file system. Before converting, one is advised to spend some time to learn the benefits of both systems, and since conversion takes a little bit of time, your needs should be the ones to determine which system should be embraced. It’s always good idea to back up your existing data before starting to convert. There are several ways to convert FAT-32 to NTFS which are discussed below.

  • Browse with caution – Most viruses enter your computer as a result of clicking on pop-ups or untrustworthy website links.

iPv4 and iPv6


Most of my co teachers with windows 7 Starter Edition OS laptops have problems accessing the wifi connection in our school. Everytime I set the IP configuration, I can see iPv4 and iPv6. I wonder what makes iPv4 different from iPv6. I came across this site from Mashable which is the answer to my query.

Here it goes...

The Internet has run out of Internet addresses… sort of. Perhaps you’ve heard the news: the last blocks of IPv4 Internet addresses have been allocated. The fundamental underlying technology that has powered Internet Protocol addresses (ever seen a number like 99.48.227.227 on the web? That’s an IP address) since the Internet’s inception will soon be exhausted.

How Computer Viruses Work

A computer virus is a program that reproduces by attaching itself to another program or document. Similar to a biological virus, the virus has a code which is executed when the infected program is run.
This is the general way most viruses work:
  • When an infected program or file is opened, the computer virus attached to it is automatically activated.
  • The virus modifies a computer program’s code so when a user starts the program, the virus code runs instead of the normal code.
  • The moment the virus code becomes activated, the computer will then be under its full control.
  • The virus aims to replicate and spread. Thus, it naturally looks for prospective targets to infect.

Internet Fax

Internet fax is a type of online service that provides subscribers with the ability to send and receive faxes without a fax machine. Instead, Internet access and an email account is all that is required.

Discover the advantages of technology nowadays! Read further on the best Email to Fax Service reviews!


To use an Internet fax service, a subscriber signs up for a small monthly fee and is assigned a fax number. When a fax is sent to the subscriber's number, the service accepts the fax, turning it into a file that is forwarded to the subscriber's existing email address.

To send an Internet fax, the subscriber creates an email. The fax content can be written in the body of the email, and attachments are normally permitted. The destination fax number is entered in the "To" field, along with "@" and the Internet fax service name. For example, if the fax number were 1-550-234-5678, the email would be addressed to 15502345678@site.com. In the "Subject" field the user enters the name of the recipient, "Attn: Mr. Jam" for example.

A small toolbar, available for download from the Internet fax service, is used as a plug-in inside the email program. Clicking on the "Send" button on the toolbar sends the email to the Internet fax service. Upon receipt, an automated program converts the email to a fax format, then faxes to the number supplied in the "To" header. The recipient receives the fax normally, through his or her fax machine.

This service can be very convenient. Of the many advantages, your assigned fax number is active 24 hours a day, so that your account can accept faxes around the clock. Contrast this with using a fax machine, which relies on your phone system being free to accept a fax. For those that use one phone line for fax, telephone, and dial-up, an Internet fax service is especially handy. Internet fax services also save paper and fax toner, and do not rely on a serviceable fax machine. All faxes are sent and received as files. They can be printed by choice, but it isn't necessary.

A further advantage of an Internet fax service is that the subscriber does not need to be familiar with faxing software or fax machines. The convenience of sending and receiving faxes by using the familiar email interface appeals many people.

One of the best features of Internet fax services is that many offer toll-free fax numbers for the U.S. and Canada, so that your U.S. and Canadian clients can fax you for free. Sending faxes is also free of phone charges for the subscriber, as he or she is only sending emails.

When looking into Internet fax services, consider a service that offers a secure website. This provides a mobile "portal" to send/receive faxes while you're on the road or away from home. Confirmation of sent faxes should be standard, so you can be sure your client got your communication. The ability to send to more than one fax number at a time can also be valuable. Check for a page capacity, as some services may limit the amount of pages the subscriber can send/receive in a month.

Fighting Unknown PC Problems

Hardware problems are quite difficult to tackle, worse if under Windows. There was once when installing a software, I accidentally inserted the Audio hardware diskette. Thinking it was harmless, I went on, thinking I can always "undo" everything again. How wrong was I. The next moment I restarted Windows, I got the blue screen of death. Yeah, Windows is very nasty when it comes to hardware.


Find The Culprit


Always calm down. Try to solve the problem yourself before resolving to formatting or sending to your computer dealer. First, know what's happening and the cause of it. In my case, the installation must have overwrite my old setting and replaced the wrong file. There must be a reason why Windows is acting improperly.


Logging Back On


First, try to log back on. If you can't log into Windows, don't panic. Restart the computer. When the text "Starting Windows 98..." appears, press F8. A menu will appear. Choose "Safe Mode" to continue. Safe mode will take some time to load. When you are in Windows, go to Control Panel, System. Click on the Device Manager tab. Find the faulty hardware driver and delete it. Open autoexec.bat and config.sys (both are hidden files in your root directory) with notepad. If the hardware is a CD-ROM or sound card, it will probably write add some lines. Check whether there are backup file (autoexec.bak, autoexec.b~k e.g.) since most installation will back up the 2 important files. If there is, simply replace them with the backup files. If there isn't, put "REM " in front of every line that loads the hardware.


Repairing


When you restart, your computer is probably ok, since you have deleted all instances of the hardware drivers. But the hardware isn't functioning. re-install the hardware drivers, restart and you're done! If the problem persists, your probably have a system conflict go to the next page for more.
