What are the Main Functions of Operating Systems?
An Operating System’s main purpose is to efficiently manage computer resources. This function can only be performed with the assistance of the user, so it is important that the user interface is well designed and maintained. The OS functions allow the user to perform the tasks that have been assigned and help them to do so in a professional manner. App software provides the services. The user can also control the device to perform various functions. OS also focuses on security and storage to assist the user and complete system tasks.

What is the Operating System?
The Operating System is a computing device that assists the user in performing the tasks it has been assigned. The Operating System manages hardware and software and provides resources for the user. OS is an intermediary between hardware and input, output and memory allocation functions.
OS manages the following resources: input devices, output devices and storage devices. Input devices are keyboard and mouse. Output devices include monitors, printers and scanners. The network device is the modem, etc. Storage devices can include both internal and external storage drives.

The kernel, user interface and application programming interface are the main components of OS. The kernel provides basic control to the devices. The user interface allows for user interaction with the system. Application developers use the interface for programming to create the code.

Operating System Functions
OS provides security for user data and prevents unauthorised access. Passwords can be used to protect data. OS will ask for the password if an unidentified user inspects the files. The data is then protected. A password protects the system. This allows for verification of who is logging in to the system.
The OS improves system performance. It monitors system response times after service requests are made. OS detects any abnormal variation in system response time and alerts users. Any virus attack can cause high or low variation. Notification is sent to the user to make any necessary adjustments.
OS can account for different applications and tasks as well as the number of people who perform the tasks. This allows you to see the number of users as well as the frequency of their application usage. For applications with more usage, storage can be allocated to your system. This allows you to keep track of your user and the various tasks that use up storage.
These errors can be traced back to changes in hardware. This log allows the user to identify errors in hardware and software and make the necessary adjustments to the system. This helps prevent the computer from malfunctioning.
The computing system is used by many people. OS allows users to coordinate and collaborate with compilers, interpreters, and assemblers. This ensures that the system is in order and users don’t get confused by the different software.
