An operating system is responsible for managing a computer’s resources. These resources include memory, disk space, and CPU cycles. It also helps to ensure that programs run efficiently. It manages processes, such as logging and accounting. The operating system is also responsible for protecting the computer from viruses and unauthorized access. It is also responsible for controlling access to various resources, such as the Internet. The operating environment of a computer is the first layer of defense against attacks from malicious software.
In addition to managing memory, operating systems also provide services to other software. The main role of the OS is to manage input and output, coordinate with other programs, and allocate memory to various processes. The operating system manages these resources and allocates them to the various applications on the computer. It manages memory without interfering with other applications, preventing crashes. And because it can handle multiple processes and tasks at once, an OS is crucial in computer systems.

Another key function of an operating system is to coordinate the use of resources. This allows the software to allocate resources to specific tasks, such as programs. It also manages files and processes, and assigns interpreters, compilers, and assemblers to users. A well-secured OS will protect the computer from external threats. The operating system also monitors the hardware to detect errors and ensure that it’s working properly.
