How to extract an iso file in Linux?

mkdir <target_dir>
mount -o loop -t iso9660 <your_iso_file> <target_dir>

Note: There are many other ways to extract the contents, this one works faster to me in command line.

Byte Messaurement

Bit : Either 0 or 1

8 Bit = 1 Byte

1024 Byte = 1 Kilo Byte (KB)
1024 Kilo Byte = 1 Mega Byte (MB)
1024 Mega Byte = 1 Giga Byte (GB)
1024 Giga Byte = 1 Tera Byte (TB)
1024 Tera Byte = 1 Peta Byte (PB)
1024 Peta Byte = 1 Exa Byte (EB)
1024 Exa Byte = 1 Zetta Byte (ZB)
