In this tech era, advancement in tech gadgets has also developed the ways of operating the gadgets. The latest and innovative tools have been trending in the technology world. In the past, CDs or DVDs were used to install Windows 98, Windows XP, and many others. Now, the flash drives have occupied the place of the CDs.

People prefer to copy and burn data onto a USB drive as CDs used to get out of order after a few scratches over it. Sometimes, over time, the data available on the CD began to disappear or showed faults. It is the reason that the USB drive is considered a safer and reliable source these days.    

What is an ISO file on Mac?

An ISO image is created on the Disk Utility Program available on Mac. The Disk Utility program is part of the Mac OS X operating system. An ISO file is an archive-based file. It carries an identical copy of the data available on optical disks like CD, DVD, or other portable devices. An ISO image is formatted in ISO 9660 image format.

Why ISO files are required?

 An ISO file carries backup data of the optical disc. ISO file is required to make an identical copy of a CD or DVD. Later on, this identical copy may be used to write or burn a CD and helps to deliver the data to any portable device. Why the ISO files are required? Some of the logical reasons are given here for better understanding:

  • The BIOS requires a bootable device to reboot. It automatically starts searching the booting sector. So, just copying the file does not include a bootable sector.
  • When the users copy a file from the hard disk to a flash drive, it cannot initiate installing from the flash drive. Copying the data from any device to the flash drive does not include all essential elements of installment and booting.
  •  Zip files or archive files other than ISO files cannot carry or store the whole data of the hard drive onto a USB device.

In simpler words, an IOS file carries all data and information with the bootable- sector. So, ISO is a bit by bit copy of the whole data including all information.

The difference between copying and burning – a misused term

The term “burning” gets often mixed with copying. Both are two different terms. Copying the files from or to the DVD or flash drive means copying the surface data. On the contrary, the burning of a CD or DVD refers to writing a CD or DVD. The burning of the CD enables the cloned or digital copies of the available data on a specific device.
