If we turn back the pages of history, we’ll see that everything has changed; evolved to be real exact. What used to be a big and surprising thing in the past isn’t much of a deal today. One of the biggest contributors in this revolution, computer technology has itself undergone a big change.

Anyways, I’d like to dedicate this article to our old friend Floppy which was a part of this revolution, which has helped a lot in the past when there were no optical mediums like CDs and DVDs, which was the only means of transferring data from one computer to another for a long time. It has really been a good friend but it needed to be replaced, by something stronger and much useful recordable devices and it was too by CDs and DVDs. A single CD can hold approx. 650 MB data and a single DVD up to GBs which is hundreds and thousands or times greater than what a Floppy can carry. Additionally, CDs/DVDs can store music and video files that can be playable in other devices. And even when we consider the price, CDs and DVDs still come to be victorious. A pack of 100 blank CD-R cost around $58 (0.58 each) and a 20 blank DVD pack cost around $42 ($2.10 each) which is very much cheaper in compare to 1.44 MB storing capacity having Floppies which are nowadays in the midst of extinction and are very hard to be found in shops (approx $44 for 100 floppy disks pack, $0.44 each).

I really hope someone comes up with some new technology and I can again put floppy disks inside my floppy drive’s mouth instead of just using it as a coaster to put drinks on. Ya you heard it right. I’ve been using my floppies as a coaster but even for that spot damaged CDs and DVDs are replacing it. What a tragedy???

Do you hae a updated strong Antivirus installed on your PC or Laptop? Are you sure, it will get your system immune of any kind of attacks of viruses? The answer maybe yes, it does. But what if your Antivius is sleeping? You might get surprise by the term ‘Sleeping’. Let me clear you this. You all know that when system boots, your Antivirus is not yet activated. At that time, it may be called as ‘Sleeping’; if your pen drive or floppy, which might have unknown hidden viruses that have brought from others, is inserted may copy to your system automatically. And your system may be infected. Don’t you believe?

In computing, booting (booting up) is a bootstrapping process that starts operating systems when the user turns on a computer system. A boot sequence is the set of operations the computer performs when it is switched on that loads an operating system. The boot device is the device from which the operating system is loaded. A modern PC BIOS supports booting from various devices. These include the local hard disk drive (or partitions on a hard disk), floppy, optical disc drive, a SCSI device, Zip drive, LS-120, a network interface card using PXE and a USB device (USB-FDD, USB-ZIP, USB-CDROM, USB-HDD, USB flash drive). Typically, the BIOS will allow the user to configure a boot order. If the boot order is set to “firstly, the DVD drive; secondly, the hard disk drive”, then the BIOS will try to boot from the DVD drive, and if this fails (e.g. because there is no DVD in the drive), it will try to boot from the local hard drive. So, if you leave a pendrive or floppy disk in your PC unplugged, then during booting process, your system may scan it and the viruses may be loaded to your system before your Antiviruses get awake. So, don’t insert them before or during the OS booting.

So always it’s safe to take out floppy, pen drive or any removable disks out when you are not using them. Because, they might cost you pay very high. And also always scan them by your trusted updated Antivirus after inserting them in their drives.
