Iso file

From where did ur friend got the offer letter? wat is the business /serviceline...need more clarification???????

I dont know ur talking about which ISO files but what i know about them is:

ISO files are useful for keeping backups of CDs and DVDs and for storing the contents of CDs or DVDs on hard-drives or uploading and downloading them on the internet.The easiest way to think of an iso file is more like a "zip" or "cab" file, only without the compression. An iso file contains the image of a disk. That means it contains all the files and folders that were on that disk, much like a zip or cab file contains a collection of files and folders.
