Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I really don't know what type of application it is. Is there any way so that I can find it out? Otherwise I have to wait till tomorrow to ask the person from whom I got it. Unfortunately he doesn't know anything about linux so that he can troubleshoot the problem. He just runs the file and that's the way he gave the file to me as I need the output of it.
It is Red Hat Linux....I had to install this old version to get something running which was not compatible with other version.
My system device is showing "Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] DRAM Control. Does it mean a 64bit OS?

Perhaps you ought to start from the beginning with what you're trying to do.
That only means that he has a k8 64 bit capable cpu. But 64 bit cpus can also run 32 bits OSes. And that's what we are trying to determine. If he is running a 32 bits OS he will never be able to run that program. Period.

What does i686 athlon i386 GNU/Linux exactly mean?
It means that your OS has been compiled for 686 athlon processors, and hence, it's a 32 bits OS. What is confusing you is that x86_64 cpus can run x86 (32 bits) code as well. So your cpu is capable of running 64 bits applications. But right now, it's working in 32 bit mode.
You can't run 64 bits apps under a 32 bits Linux OS, it doesn't really matter which cpu do you have. That is, unless you resort to virtualization of any kind. If you find a virtual machine like vmware or virtualbox that can emulate a 64 bits cpu under a 32 bits linux, you could install a 64 bits linux version inside the VM, then you should be able to run that program inside that VM.
Or you could just delete your 32 bits RHEL, and install a 64 bits one instead, since your cpu is capable of running it.
AS i92guboj has summarised, the OP has a 32 Bit version of RHEL 4.7, trying to run a 64 Bit app. This will not work.(!)
The OP either needs to get a 32 Bit version of the app, or re-install RHEL 4.7, 64 Bit version.
