How A Software Actually Works On A Hardware

Posted by Tushar Bedekar

Hi,Today We are going to discuss a new topic which may be very old but important one, also a big question in front of us.

What is a Program me?

As we all know that a program me is a group of instruction which is needed to be executed by the machine like a computer to perform a certain task.but the biggest question is that how these group instruction are executed on the hardware to perform a assigned task.Basically these instructions which are being executed are itself a group of micro instruction an microcode.which are executed on any machine to execute a one particular instruction. now,

what is programming?

Actually the programming is nothing but Def:- provide (a computer or other machine) with coded instructions for the automatic performance of a task.But This definition does not gives the full idea about what actually the programming is? and also it does not gives the idea about how the software runs on the hardware.

As we all have listened about PLA`s(programmable array logic), PAL`s (programmable logical array) and also about FPLA (field programmable logical array).Basically these are the logical devices consisting of arrays of AND & OR gates and also other different supporting devices.These devices may be Hardwired or may be re-programmable.

How To program me these devices?

Basically devices consist of programmable AND & OR gates.That these arrays consist of fussing and re fussing technology.These fuses may be burned and or lay intact as per the requirement.This fussing can be done generally by supplying a sufficient amount of current through the fuse.

Types of fuses:-

Metallic Fuses.
Diode/Transistors fuses
Silicon Fuses.Etc

So by fussing the different fuses the programming can be done.
