What are the 10 features of an operating system on a computer?

Operating system has so many features that the end user can take into their life and use the computer and operating system functionality to provide the service of the end user such as: a program to compute two or more than two input values as a query to search on the search bar then the end user finds their relative results on their search application which is provided by the operating system to the end user in the form of a service on the computer or a smartphone devices also.

The user can access the file and save information inside the file to retrieve the information to get the output data when the user searches a query and the search tool finds the query which is saved inside the file and optimizes the result from the flat file.

The flat is based on the text information provided to the end user and created by the end user through the tool app of the operating system.

Here are ten key features of an operating system on a computer:

1.Process Management:

Handles the creation, scheduling, and termination of processes. It ensures efficient execution of processes and allocates CPU time to processes.

The creation in operating system means the program file or database file can be created and execute the new program on the cpu to compute it and provide the output data to the output unit on the computer system where the output unit of operating system controls the output resource on the computer system as a program to control and sends the instruction to perform a task on the computer to get the output result on the computer from the program which has been executed on the cpu.

Scheduling of the program is that the program is executed when the previous executed program has to computed on the cpu to provide an output data to the output unit and the next program is ready for execution and computing also on the operating system which is also a part of scheduling on the cpu on the operating system on the computer.

Termination of program is a program that can be terminated when the computing process has been completed according to the given condition included into the program file and it gives an output data then the program is terminated on the cpu according to the operating system on the computer system. The termination of a program is also known as the closing of the program after completing their computing working by the cpu.

2.Memory Management:

Manages the allocation and deallocation of memory space to programs in need. It keeps track of each byte in a computer's memory and ensures optimal memory usage.

Memory manages by the program of operating system to ensure the space for the program to store temporarily for processing the program or execution of program and the memory management section of the operating system manages the memory according to the file size of program to execution and store temporarily on the primary memory or temporary memory and the permanent memory on the computer system.

3.File System Management:

Provides a way to store, retrieve, and organize files on storage devices. It manages file permissions, organization, and hierarchy.

The storage device is the permanent memory to store the data as the operating system takes input instruction from the end user and the file can be stored according to the given instruction to the operating system as a tool application to perform that task on the computer system to store the file at the particular memory address. It is used to retrieve the files and its information by the user as the user gives a command to open or run the file then the user gets the information from the file through the operating system accessing and retrieving the files from the storage device.

The end user of the operating system can create the file or organize the file into the storage device and the storage device used as the permanent memory for file storage which is given a command by the end user on the operating system.

4.Device Management:

Manages hardware peripherals like printers, disks, and monitors. It provides a way to interact with and control these devices through device drivers.

The operating system controls the hardware resources that are connected to the computer system such as:- the storage device, input devices and output devices and the driver tool application of operating system can disconnects the hardware resources on the computer system, in that way the hardware resources cannot work with the operating system but it is good and usable with different operating system on the computer system. The user can allow the permission to access the connected hardware resource that the user can use on the computer to operate and controlled by the operating system to get output data from the output hardware resource and storage devices are used to store the database and files where the input devices are used to connect sends the input instruction to operate the operating system on the computer system which is possible through the driver tool application on the operating system on the computer.

5.Security and Access Control:

Protects data and resources from unauthorized access. It includes user authentication, encryption, and permissions management.

The user has to access their user account created by the user on the operating system and the security model interacts when the user applies the security layer over the user account to open after verification of the user. The user can access their account when the user verifies their details which the user has been to verify at the security layer and the program asks the details such as:- the username and password is a basic type of verification to confirm the details set up by the account user on the operating system, the user also applies the additional security access if the user applies the additional security option such as:- security question and their answers, secret code after username and password verification, the OTP code verification or email code or token authenticator to provide token at the limited time, biometric input data verification etc. On the security model for the end user.

6.User Interface:

Provides a user interface (command-line or graphical) for users to interact with the computer system. It includes desktop environments, windows, menus, and icons.

User interface depends on the operating system type available the interface such as:- The command line interface is used to operate the operating system using the command line operated by the end user.

The user can operate the GUI form of the operating system through monitoring the graphics because the GUI means the graphical user interface of the operating system to provide the display form of program in the given particular format displays to take input values from the input resource on the program to provide the output data which is also gives the output data to the output interface on the form of the program on the operating system.

7.Multitasking:

Allows multiple tasks to run simultaneously by efficiently managing CPU time and resources among them.

Multitasks can be performed on many types of tasks at the same time and the user uses the applications depending on the ability to use many types of application at the same time. The operating system runs the multiple applications according to their capabilities to run in their environment on the computer system.

The task means the application which is a unique task and different from the other type of application software. Applications have a task depending on their category of application software to perform a task to provide the service to the end user and provide the output data as a result or solution to the end user.

8.Networking:

Manages network connections, data transmission, and communication between computers. It includes support for various network protocols and services.

Network feature is also operated by the operating system and allows it to connect to the network device to make a network model to connect many computers through the data cable or wireless medium. The networking system through the operating system is to provide the service of sharing the data, information and database to the connected user on the network model through the same network device and the computer system in the network model. The user can makes easy their task by using the many connection of the user through the network model to prepare a same task quickly as they are connected to each other through the network device to the operating system on the computer to provide the service to sends the files which has been prepared by the other users and complete the project task on the network model quickly.

9.System Performance Monitoring:

Monitors system performance and provides tools for analyzing and optimizing performance. It includes task managers, resource monitors, and performance logs.

The user can monitor the task which is running currently or executed and opened a program or an application can be used to see through the task managers types of application included in the Operating System to provide the service of checking the details and performance of the application which is running on the operating system environment at that time and shows the memory uses in the computer system.

The resources monitor types of applications are used to display the details of resources of the computer system that are connected to the computer through the port externally or internally on the computer system.

The performance logs means the performance application of the operating system to provide the information about the computer system performance and the uses of CPU, GPU, register, latches, RAM and ROM depends on the computer system and operating system tool performance application software on the computer system or the smartphone devices.

10.Error Detection and Handling:

Detects and handles errors that occur in the system. It ensures system stability and reliability by managing faults and providing recovery mechanisms.

The operating system detects errors and it is used to handle that can be solved by the operating system itself when the errors occur during the operations are applied and the error occurred then the operating system can handle these types of errors and solve itself using the recovery mechanism of the operating system.

Sometimes the operating system recover their problems by checking the hardware such as:-

A storage device to checking itself when the user starts the computer the operating system self checking system and scanning the files which may be damage or not and the operating system handles the problems and solves them to shows also the report to the end user in the form of the notification or pop up forms displays of the operating system to show all types of files are safe and the user is ready to operate the operating system on the computer system. There are some errors detection and handling key points following below here:-

Error Detection and Handling in an operating system refers to the mechanisms and techniques used to identify, report, and recover from errors or exceptional conditions that occur during system operation.

There are some key points are included on the errors detection and handling following below here:-

1. Error Detection:

Identifying hardware or software faults, such as memory parity errors, disk errors, or invalid user input.

If the application software does not have a sequence of different types of program files then the errors can be detected in the form of scheduling errors or other types of hierarchy of program connected to the main program files getting errors. These types of errors are software faults.

The hardware occurs when the new hardware which is not working due to different types of version of recourse can show the error and shows the notification to remove the hardware which is not working with the operating system.

2. Error Reporting:

Notifying users, administrators, or other parts of the system about the error, often through error messages, logs, or alerts.

The errors show to the display screen on the monitor output device to provide the notification form to read carefully the message and understand the errors by seeing the report on the operating system on the computer.

3. Error Handling:

Taking corrective actions to recover from errors, such as:

    - Restarting processes or systems

    - Rolling back transactions

    - Allocating alternative resources

    - Terminating faulty programs

    - Providing fault-tolerant mechanisms

Effective Error Detection and Handling ensures system reliability, availability, and maintainability, preventing errors from causing data loss, system crashes, or security breaches.

What are the 10 features of an operating system on a computer?

There are some points on the computer system and operating system related to the topic of “What are the 10 features of an operating system on a computer?” following below here:

Here are four features of operating system following below here:

• To provide the interface in the form of GUI 

• The operating system controls the peripheral

• Access the memory devices to process data

• Security features is also most important for the end user to protect personal database

Let's discuss the points above about the computer system and the operating system related to the topic of “What are the 10 features of an operating system on a computer?” explanation following below here:

Here are four features of operating system following below here:

To provide the interface in the form of GUI 

The GUI is a graphical user interface which has been developed for the end user to operate the operating system using the graphics tool and without any use of command line to the operating system.

The user easily understood the operating system in the user interface of graphics to make a decision on the option with mentioning their name or title of the option or logo to display to get the idea which indicates the logo is designed for their program to perform a task and get the result.

For example:- The user sees the option which has a logo indicating the printer then the printer is used to print out to get the hardcopy of the document or image file to the end user.

The operating system controls the peripheral

The operating system controls the peripheral means the user commands to perform the input peripheral to perform means to send the input instructions to the computer and the user commands to operate the application to perform a task to print the data from the application software.

The application software processes the given command from the input peripheral and the task performed by the printer to provide the hardcopy of the data from the application as the application gives an instruction to print out the data that means the output peripheral performs a task given an instruction by the application program which processed the input instructions that given by the end user through the input peripheral.

In the Operating System the application is a tool application software provided by the operating system which includes the printing option to print out the data.

Access the memory devices to process data

Access the memory devices to process the data to retrieve the data from the storage device of the computer, the operating system can access the memory address of the file where the user has saved the file to provide the database when they retrieve the information.

The storage device is used to access the file through the memory address that is accessed by the program to find the file from the search tool application on the computer.

The storage device is also used to install the operating system or system software and their database file to process the data from the storage device accessed by the program file and run the file on the operating system. If the storage device is mechanical devices then the operating system is slow to work and process but the electronic based or flash based storage device is used to install the operating system into it then the operating system better processing their task or working fast or better performance.

Security features is also most important for the end user to protect personal database

Security features is also used to provide the protection of the end user on the operating system the user saved their personal database into the storage device and the end user wants to protect their personal database then the security layer over the user account which has been opened in the operating system to access the user account after the verification of the account through the security layer which included basically the username and password or user account name and password.

Some operating systems provide the option to apply more security on the user account to access if the connected user account has saved the sensitive database into the storage device of the computer system.

The additional security layer included the secret code after the verification of the username and password. The eye scans input data to verify the identity, the finger or hand patterns are used to verify if the object based verification available on the security model of the operating system.

The security answers are also set up based on the relational database model to apply on the security layer to add more protection layer over the user account on the security layer. The end user protects the user account on the operating system in the security model to set up the question and answer two or more questions and answers for verification set up and saves the question and answer to verify when the user enters their account on the operating system to protect their personal database or sensitive database or official database depends on the security level applied on the user account which connects the database categories for the end user.
