What are Operating Systems? Basic Definitions and Concepts

Operating systemsA computer's hardware is the fundamental software that enables communication between the user and the computer's hardware. It manages all the computer's resources, enables applications to run, and provides an interface to the user. Without an operating system, a computer's hardware is just a pile of metal and silicon; it can't perform meaningful work or interpret user commands.

Operating systems are a cornerstone of modern computing. They run on all kinds of devices, from our smartphones to supercomputers. Their role is to abstract the hardware, allocate resources fairly, and enable applications to interact securely with each other and the hardware. Operating systems enable users to run programs, access files, and manipulate the hardware.

Basic Features of Operating Systems

• Resource Management: It manages resources such as CPU, memory, storage, and input/output devices.
• Process Management: Controls and manages the operation of programs (processes).
• Memory Management: It shares and manages memory among different processes.
• File System Management: It allows editing and accessing files and directories.
• User Interface: Provides an interface (GUI or command line) that allows users to interact with the system.
• Security: It ensures protection of the system and data against unauthorized access.

Operating systems perform various tasks to ensure the efficient operation of a computer. They handle core functions such as memory management, process management, file system management, and input/output device control. They also implement security measures to protect the system from malware and unauthorized access.

There are different types of operating systems: desktop operating systems (Windows, macOS, Linux), server operating systems (Windows Server, Linux), mobile operating systems (Android, iOS), and operating systems for embedded systems. Each type of operating system is designed to meet specific needs and has its own unique features. The evolution of operating systems continues in parallel with the development of computer technology. This journey, from UNIX to modern systems, forms the foundation of the IT world.

History and Development of UNIX

UNIX, modern operating systems It is a cornerstone of the world, and its development revolutionized the field of computer science. UNIX, which began development at Bell Laboratories in the late 1960s, emerged as an alternative to the complex and cumbersome operating systems of the time. Initial versions were primarily experimental, but over time, they evolved to meet the needs of developers. While inspired by the Multics project, the goal was to be simpler and more portable.

One of the key factors behind UNIX's success is its foundation on the principle that everything is a file. This approach simplified access to system resources and devices and streamlined programming and system administration. Furthermore, UNIX's modular structure ensured that different components worked together seamlessly and allowed for the easy integration of new features. These features quickly made UNIX popular in both academic circles and commercial applications.

Development Stages of UNIX

1. Creation of the first prototype (1969)
2. Development of the C programming language and rewriting of UNIX in this language
3. The advent of the Berkeley Software Distribution (BSD) version
4. Determination of POSIX standards
5. Popularization of open source UNIX-like systems such as Linux

UNIX's portability, which allows it to run on different hardware platforms, is a key feature. Being written in the C programming language allowed UNIX to be easily adapted to different architectures. This contributed to UNIX's widespread adoption and its use on a variety of computer systems. Furthermore, its adherence to open standards encouraged interoperability among different UNIX variants.
