What is an Operating System?
An operating system (OS) is a program that controls the execution of all other programs (applications) on a computer. It acts as an intermediary between the user(s) and the hardware resources of the computer. The main objectives of an operating system are:
Convenience: It makes the computer easier to use by providing a user-friendly interface and hiding the complex details of the hardware.
Efficiency: It optimizes the utilization of the CPU, memory, disk, network and other resources by managing them effectively.
Extensibility: It allows new features and functions to be added without affecting the existing ones.
An operating system performs various functions such as:
Process management: It creates, terminates, schedules, synchronizes and communicates between processes (programs in execution).
Memory management: It allocates, deallocates, segments, pages and swaps the main memory (RAM) among the processes.
File system management: It organizes, accesses, modifies and protects the files and directories stored on the disk.
Input/output management: It handles the input and output devices such as keyboard, mouse, monitor, printer, disk, network card, etc.
Distributed system management: It coordinates the activities of multiple computers connected by a network.
Security and protection management: It protects the system and the data from unauthorized access and malicious attacks.
Why Study Operating Systems?
Operating systems are an integral part of any computer system. They provide the foundation for running various applications such as word processors, web browsers, games, databases, etc. They also enable the development of new software and hardware technologies. By studying operating systems, you can:
Understand the principles and concepts of operating systems and how they work.
Learn the design and implementation techniques of operating systems and how they can be improved.
Analyze the performance and reliability of operating systems and how they can be measured and enhanced.
Compare and contrast different types of operating systems such as batch, multiprogramming, time-sharing, real-time, distributed, etc.
Apply the knowledge of operating systems to solve various problems in computer science and engineering.
