نبرد سیستم عامل ها از آغاز تا کنون نه تنها باعث ایجاد سردرگمی در کاربران و یا حتی توسعه دهندگان نبوده است بلکه باعث پیشرفت روزافزون سیستم ها از نظر امنیت و کارایی، همچنین کاربرپسند بودن و در عین حال سادگی بیشتر در استفاده بوده است. تنها، اشاره به انحصارطلبی یک شرکت با ارائه ی محصولی بسته و یا آزاد بودن محصولی دیگر کافی نیست، بلکه باید جزء به جزء کارایی، امنیت و تمامی خصوصیات سیستم را مقایسه و بررسی کرد تا به نتیجه ای مطلوب رسید. گفتن این حرف که صرفا به طور مثال سیستم عامل هایی که بر پایه- ی هسته ی لینوکس توزیع شده اند برتر هستند و یا سیستم عامل غول نرم افزاری مایکروسافت - ویندوز- بهتر است، امری کاملا غلط و غیرمنطقی است. هر سیستم عامل با هر خصوصیتی مخاطب خاصی را برای خود داشته و با ویژگی هایی که در خود جای داده گروهی از کاربران را راضی میکند. هدف از انتشار این مقاله که مجموعه ای از مقالات، تحقیقات و اطلاعات دیگر است ارائه ی دید کلی نسبت به لینوکس از نظر مفهوم اولیه، تاریخچه، ویژگی ها، ساختار و تفاوت هایش با سایر سیستم عامل ها است.
امید است این مقاله - هرچند مختصر- برای همه ی دوستان عزیز مفید بوده و مورد استفاده قرار گیرد.

- پیدایش لینوکس
