While downloading Fedora Linux, they offer two options for download that I don't know the difference to: x86 and i386. So what'sthe difference between them?
Answer
i386 is just one the first model in the x86 familly of processors, and instructions sets.
For more informations, you might want to take a look at :
Quoting the second page :
The term x86 refers to a family of instruction set architectures[1] based on the Intel 8086. The term is derived from the fact that many early processors that are backward compatible with the 8086 also had names ending in "86".
And, quoting the first one :
The Intel 80386, also known as the i386, or just 386,[1] was a 32-bit microprocessor introduced by Intel in 1985. [...]
As the original implementation of the 32-bit extensions to the 8086 architecture, the 80386 instruction set, programming model, and binary encodings are still the common denominator for all 32-bit x86 processors.
This is termed x86, IA-32, or the i386-architecture, depending on context.
