A Comparative Study of Modern Operating Systems in terms of Memory and Security: A Case Study of Windows, iOS, and Android
Keywords:Windows, operating system, Android, and iOS.
Modern computer systems have an operating system, which serves as an interface between the device and the user and has the dual objectives of making the device easier to operate and making optimal use of device resources. The operating system offers some level of computer security like user authentication, file permission, firewall, encryption etc., but occasionally, problems develop due to societal or technical challenges like: vulnerable to malicious programs and viruses, which can cause the system to become sluggish or malicious actors be able to have an access to confidential user data, which compromise computer security. This comparative study provides insight into each of these operating systems and their relative strengths and weaknesses. The paper begins by discussing the concepts of memory management and security in general and then examines the specifics of each OS's memory management and security features. A case study of three popular applications is presented to illustrate how memory management and security features can be used in practice. The results of the comparison show that while each operating system has its own advantages and disadvantages, Windows is generally the most powerful and secure of the three, while iOS and Android offer more flexibility and ease of use
