Operating System Theory and OS Concept Map

Image
My exploration of operating systems theory has unveiled a profound understanding of the fundamental concepts that underpin these critical pieces of software. Operating systems (OSs) are the cornerstone of modern computing, providing the foundation for software applications and user interactions. Understanding the underlying theory behind OSs is crucial for computer science professionals and users alike. Processes are the fundamental units of execution in an OS. They represent running programs and manage their resources (CPU time, memory, etc.). Process management is the cornerstone of multitasking, enabling the operating system to handle multiple programs concurrently. This involves managing the creation, scheduling, and termination of processes, ensuring their smooth execution. The concept of memory management is crucial for efficient utilization of system memory. OSs are responsible for efficiently allocating and managing memory among multiple processes. This includes virtual mem

Network Security Connection

Network security is when a computer’s network and data, in both hardware and software, are protected from people trying to access them who should not be accessing them (Vahid & Ly secky , 2019) . Network security has different programs that are use d to prevent any unauthorized access. These programs  are called firewalls, encryptions, and antivirus so ftwares , just to name a few. They are used to protect from cyber-attacks, such as viruses, malware, and hackers. There is ne arly 1 c yberattack every 39 seconds, (over 2200 attacks each day) which means that companies and even regular people are always at risk (Fox, 2023). In the past, cyber-attacks were not so common, but since we are now in an era where there is a vast amount of information that is shared and stored electron ically, network security has advanced to h andle the challenges that come with protecting computers. Many personal computers and business computers have sensitive data that people will try to gain to u
