What do you mean by the term “To operate the machine of a particular device which is used for specific work” in the reference of user interface between hardware and user operating system?.

To operate the machine of a particular device which is used for specific work:

This means that the operating system can control the machine and their peripheral device integrated on the board of PCBs where PCBs stands for Printed Circuit Board in the electronic device. The operating system interacts with all peripheral devices that are inbuilt on the board.

The peripheral device is necessary for the operating system.

The CPU and their processing work can be displayed by the operating system such as task management systems. You can see the CPU usage which means that “how much percentage CPU used for your operating system. Other usage you can check when you use an application software in the computer system, it shows 80 to 90 % percentage of CPU used and currently using. All that can be shown in the task management system application of an operating system of your computer system.

The device, if you have connected to the computer system using a port through wired connection or wireless connection, the operating system can be able to receive the request of connecting the particular device. The operating system can control the device such as: giving a command to the printer to print the hardcopy and get the detail of the document file on the specific format of a page through the hardware resources or output device of the printer.

 

What do you mean by the term “To show the interface of the machine or hardware device of a particular address through the output device” in the reference of user interface between hardware and user operating system?.

To show the interface of the machine or hardware device of a particular address through the output device

The interface of the machine or hardware device means that the computer system receives the request the particular hardware device and show on the monitor screen in the form of the notification of “detecting device” or “detected devices” and in other words can says “new devices found” in according to the operating system prefix default in the programing structure shows the notification statement, also it is depends on the condition of statements and their  meanings.

The “particular address”  means the port where you had connected to the computer system such as USB, Ethernet port, HDMI port etc. and the monitor shows the notification of address of connecting through a particular port in the computer system.

Manage the processing unit with smart calculation of input and output instructions

Manage the processing unit with smart calculation of input and output instructions that can be done by the Central processing Unit. The CPU uses the ALU section to solve the instruction which is coming from the input device and ready to output instruction to the output device.

The ALU solves the instruction of input with the help of their arithmetic and logical function stored in the Arithmetic and logic unit in the CPU of the microprocessor of the computer system.

The operating system receives the instruction of input from the input device and calculates the instruction in the processor. After processing the instruction the final result is controlled by the CU control unit and the control unit is prepared, the instruction sends to the output unit and the output unit takes the output result and sends it to the output devices.

What do you mean by the term “To provide the accurate output results to the user where the user wants to desire output from given input instructions” in the reference of user interface between hardware and user operating system?

There are some points on the term of "To provide the accurate output results to the user where the user wants to desire output from given input instructions" in the reference of user interface between hardware and user operating system?

When the user sends the instructions to the computer system the CPU processes the instructions from the input device and input unit, the CPU processes the instructions and the instructions calculate with some arithmetic and logic unit terms and formulas in the CPU.

When the CPU get the output is ready to sends to the output unit, CPU sends to control unit to control the output processed instruction from the ALU of CPU and ready to prepare the instructions then sends to the output unit and output unit sends to the output device in the form of desire output for the user who wants to receive to the accurate result from the computer system.

Such as when the user using the calculator application and the keyboard is an input device for the computer system.

The keyboard sends the instructions of two numbers are 2 and 4 with one instruction of operator sign which is addition "+" from the number board section of keyboard the computer system receives the instructions from the keyboard and process the instructions with add sign operator, then CPU takes decision on the two numbers to add according to given addition operator in the application of computer system using the arithmetic and logic unit.

Then the CPU prepares output after calculating the instructions and gives output to the output unit and the output unit sends it to the output device monitor.

The processed output is 6 shows on the screen through an application of calculator on the computer system.

What do you mean by the statement of "Self repair functions in the back-end working of system software re-fixing the unwanted bugs and repair errors" in the reference of hardware and user interface of an operating system?

What are the disadvantages of the user interface of an operating system between hardware and users?

There are some disadvantages of the user interface of an operating system between hardware and user points following below here:

• User interface creates battery consumption problem in the laptop and other device

• User interface takes more electricity if there is heavy in their space with so many functionality

• User interface takes more loads due to the higher space uses of the storage devices

• If you choose many program to open it then the user interface creates deadlock condition 

• New hardware detecting problems due to low version of user interface 

Let’s takes explanation of these points above listed of disadvantages of user interfaces between hardware and user following below here:

User interface creates battery consumption problem in the laptop and other device

The user interface creates battery consumption problems in the laptop and other devices such as smartphones which are other forms of computer.

The user interface consumes the battery power if the new version of operating system and system software installed on the device because the new version of operating system is too heavy according to the older version of hardware devices, and the reason is it cannot hold capacity to operate on the electronic PCB circuits. Where PCB stands for printed circuit board.

User interface takes more electricity if there is heavy in their space with so many functionality

User interface takes more electricity if it is heavy to operate on the electronic device. The electronic device connected a low memory storage device. The old operating system has an ability to operate the low version storage devices. This is the reason that the new operating system cannot be held by the older electronic devices and computer systems.

The new version of the operating system contains so many functions and menus which are not possible to install on the old electronic device and machines.

User interface takes more loads due to the higher space uses of the storage devices

User interface takes more loads due to the low memory of volatile memory such as RAM.

So the volatile memory needs to operate the operating system and hold its spaces according to the capacity of the memory.

The new version of the user interface of the operating system has so many functions and program or system tasks need more memory space which is not capable of low memory of volatile memory.

If you choose many program to open it then the user interface creates deadlock condition 

The deadlock condition is known as hanging of the operating system on the computer system or mobile device which is also a form of computer.

Deadlock condition is when one user gives a command to the computer for processing but the computer already hangs on to the other circle of processing and resource controlling of the computer decision this makes deadlock condition. In case the computer does not respond to the user when you are giving a command.

New hardware detecting problems due to low version of user interface 

If you are using an older version of the operating system or user interface and you want to connect the new hardware but the hardware is not compatible with this operating system.

Or the operating system does not give you a response to a due new version of hardware interface.

Jobs are scheduled by the OS to improve CPU utilization.

     -No Direct Interaction:

Users do not interact with the system directly. Instead, they prepare their jobs and submit them to the operator.

2. Time-Sharing Operating System

   - Definition:

This type of OS allows multiple users to use the system at the same time by sharing CPU time. Each user gets a time slice, ensuring responsiveness for all users.

Time-sharing operating systems (OS) allow multiple users or programs to share the same computer resources at the same time. There are some a points on the time sharing os:-

Key features of time sharing OS:-

1. Multi-user support:

Allows multiple users to access the system simultaneously.

2. Task switching:

The OS switches between tasks quickly, allocating a fixed time slice (time quantum) to each task.

3. Resource sharing:

Users share resources like CPU, memory, and I/O devices.

4. Efficient resource utilization:

Maximizes resource use by allocating them to tasks as needed.

Time-sharing OS benefits:

1. Improved system utilization

2. Increased productivity

3. Better resource allocation

4. Supports multiple users and tasks

   -Key Points:

     -Interactive Use:

Users can interact directly with the system, getting responses in real-time.

     -Resource Allocation:

The OS allocates resources such as CPU time, memory, and I/O devices among users.

3. Distributed Operating System

   -Definition:

Distributed OS manages a group of independent computers and makes them appear as a single cohesive system to the user.

   -Key Points:

     -Resource Sharing:

It allows sharing of resources like files, printers, and processing power across multiple systems.

     -Transparency:

Users perceive the system as a single entity even though it is distributed across multiple machines.

4. Real-Time Operating System (RTOS)

   -Definition:

An RTOS is designed to process data as it comes in, typically for systems that require immediate processing and responses. It is only processed at the real time instructions and input values to provide the output data currently using.

   -Key Points:

     -Deterministic Response:

The OS guarantees a specific time constraint for task completion.

     -Critical Systems:

Often used in environments where timing is critical, such as embedded systems, medical devices, and avionics.

Each type of OS is designed to meet specific requirements, ranging from handling multiple users to ensuring real-time processing capabilities.

How did the first operating system work?

The operating system provides the functionality on the computer system that solves specific problems which include the limited functionalities through the integrated program and database programming system for the end user on the computer system. There are so many types of functionality that are controlled by the peripheral and the operating system program. The peripherals are controlled by the operating system accessibility of IO System. The operating system process with the memory and memory management work can be performed by the operating system such as:- memory access from the memory devices, store data, retrieve data. The operating system gives instructions to the output resources that provide the output data as a solution or information to the user on the computer system.

The first operating system on the computer system:-

The first operating system (OS) was a simple program designed to manage the hardware and provide basic services for other software. Early computers didn’t have an OS; programs were run one at a time using punched cards or tapes. The operator had to set up the hardware manually for each task.

The first operating systems, developed in the 1950s, were created to automate these tasks. They handled job scheduling, memory management, and input/output operations, freeing the user from doing these manually.

Here’s how an early operating system worked:

1. Batch Processing on the operating system:

Users would submit a batch of jobs to the OS, which would queue them and execute them one by one. The OS would load the program, execute it, and then move on to the next task.

The batch is a group of programs that can be executed on the operating system to provide a large amount of output data as a solution on the computer system through the output resource for the end user. The batch files process the data and provide the output data after processing many files.

2. Job Scheduling of the first operating system:

The OS’s job scheduler decided the order in which jobs were processed. This increased efficiency by ensuring the machine was always working.

The job can be systematically processed in the computer system to provide a better processing system with the specific protocol followed in the operating system.

3. Memory Management of the first operating system:

The operating system had to manage the computer’s memory, allocating space for the programs and ensuring that no program overwrote another’s memory.

The operating system decides how memory can be managed in the computer system and the storage peripheral is used to access the memory address by the operating system program to access the memory address location to store the file and data.

4. I/O (Input / Output) Control of the first operating system:

The OS controlled input and output devices (like card readers, printers, and tapes). This allowed users to focus on writing programs, while the OS handled the details of interacting with the hardware.

Input output devices are also controlled by the operating system of the IO control program that sends and processes the instructions. The received instruction is an input and output is a processed instruction to the output peripherals.

These early systems were very limited compared to modern OSes but were revolutionary in making computers more usable and efficient.

Uses of storage device on the operating system:-

Storage device on operating system:-

The storage device provides the data to access the data from the given instruction on the operating system.

The operating system is used to be installed into the storage device to read and boot the program files to run on the computer system.

Network operating system also uses the storage device to provide the network database storage memory to the user to store the data as a backup for the client user.

The storage device is also used as a virtual memory with access of some size of memory space for the virtual memory to provide the temporary space for reducing the loads on the RAM temporary memory on the computer system.

The speed of the operating system depends on the storage device quality such as:- HDD is a mechanical device to store data and the SSD is an electronic and flash based memory device to quickly access the data, information and file etc.

Her are some other points on the uses of storage device on the operating system following below here:

Storage devices are essential components in an operating system (OS) for several reasons.

1. System Storage

The OS itself, along with its essential files, resides on storage devices (usually an internal hard drive or SSD). These files are required for the OS to boot up and operate.

Basically the program files are stored in the memory space of the storage device attached inside the computer system such as: SSD or HDD. which stores the data and program files for running the files on the operating system for functioning.

2. File Storage and Management

Storage devices hold all the files and data users interact with, such as documents, applications, media, and system configurations. The OS organizes these files using a file system (e.g., NTFS, FAT32, ext4), enabling efficient file access and retrieval.

The operating system manages the files in the storage device by accessing the memory address of the storage device to store and manipulate the files database also in the storage device which provides the stability of the database to hold and save permanently the storage device. In the temporary memory the file is stored in the temporary memory for storing the database for running the files as temporary uses on the computer without permanent storage device.

3. Virtual Memory and Paging

When the system’s RAM is insufficient to handle all active applications, the OS uses a part of the storage as "virtual memory" or a "page file." This is known as paging or swapping, where inactive data in RAM is offloaded to storage temporarily to free up space.

The virtual memory is used when the ram is full and does not any file into the temporary space on the RAM then the computer takes some memory space from the permanent storage device to give some temporary space for the virtual memory for storing some files on the virtual memory to load a heavy files which takes some memory from virtual memory. The operating system does not take all memory space from the storage device but some parts of memory space can be taken from the operating system.

4. Backup and Data Recovery

Storage devices are used to back up critical system data and user files. In case of data corruption or system failure, backups on storage devices can help restore lost data.

Data backup can be created in the storage device if the disk part has been created from the operating system to make a drive on the storage device to access a part of the backup to store the valuable files and database or sensitive database to secured when the user wants to format the storage device due to attacks on the computer through the internet accessing reasons then the backup can provide the safe database to provide the valuable database which the user saved and protected from the attacks of the malicious file on the other drives on the operating system on the computer.

5. Application Hosting and Execution

Applications are installed on storage devices and accessed by the OS when executed. Storage provides the necessary space and structure for application files, configuration settings, and user data, enabling smooth execution.

The user wants to install the new application then the application will be installed into the particular drive of the storage device which the operating system created as a disk part on the storage device to store and install the new application software on the computer system.

6. User Profiles and Settings

Storage devices retain individual user profiles, settings, and preferences, allowing for a personalized user experience when multiple users access the same system.

User profiles program files are stored in the storage device that the user can access only from the operating system to select the profile and its stored database details on the profiles of the user on the operating system on the computer system.

7. Temporary Storage

Storage devices handle temporary files created by applications and the OS. This includes caches, temporary files, and logs, which help speed up processes or aid in troubleshooting.

The temporary memory is also used in the computer to provide the temporary storage space of memory to store the file for running purposes on the computer to provide the interface and provide the service to the end user on the computer to solve the input problem and give the output data. The temporary memory reduces the loads on the cpu to process and run the program on the computer system. The temporary memory increases the speed of the operating system because it is used to store the file which is used for running on the computer. This temporary memory is used for temporary files stored for temporary uses without using the permanent storage device.

8. File Transfer and Communication

External storage devices, such as USB drives and external hard drives, allow for file transfer between systems, data portability, and external backup.

The external storage is also supported by the operating system that provides the interface of storing the data by showing the free with mention of a chart on the properties when the user wants to see the details of the memory space regulator. These external storage devices are used to get the backup space for the user to save the important database external storage device. The external storage devices are: CD, DVD, HVD, Floppy disk, Pen drive, Flash drive, Memory card or  SD card etc.

In essence, storage devices serve as the backbone for system functionality, data integrity, and efficient system operation within an OS.

What are the two main functions of an operating system?

There are two main functions of an operating system following below here:

Resource Management

It manages hardware resources such as CPU, memory, disk drives, and input/output devices, ensuring their efficient allocation and use by various programs and users.

Resources are the devices that are connected to the computer system and other devices to provide the output data to the end user on the network model also or from the single computer system.

The resources example:- keyboard input device is used to send input data to process by the operating system to perform a task on the computer to get the output response or output data in the form of display or keyboard is used to send instructions to control other output device or resource such as:- play music then the speaker output devices is working, similarly the printer output device is used to provide hardcopy as per given input instructions from the keyboard input device using a shortcut key Ctrl + p from the tool application of the operating system.

User Interface

It provides an interface (such as GUI or CLI) that allows users to interact with the computer, execute programs, and access system functionalities easily.

User interface is a display part of the user to see their activities of the user on the screen of the monitor output device and provide also the output data when the program process has been completed for the end user when the user gives somes instructions to the operating system to perform a task and the task has been completed on the operating system to show the output data to the output interface of the operating system tool application software.

User interface is a face of the operating system in a graphical user interface of the operating system Or GUI form.

The user interface displays also the response when the end user gives some input instructions to the computer system and to perform a task and the operating system gives a response depending on the instructions that comes from the input device or resource on the computer system.

Where is the OS stored?

The operating system is stored in the permanent memory device to store the program files when the computer system booting the operating system to run on the computer system then the permanent memory is used to provide the files to run on the computer system.

The permanent memory such as:- SSD, HDD, CD, dvd, HVD, portable flash drives etc. are used to provide the permanent memory for the computer system if the operating system is need to install the cd, dvd or flash drive is used to connect for booting and installation of the operating system and stored into the inside installed permanent memory such as:- SSD or HDD means the SSD is a Solid State Drive and HDD is Hard Disk Drive on the computer system.

The virtual memory is also taken by the operating system from the permanent memory device on the computer system inside the CPU cabinet of the desktop computer system.

The operating system needs a separate drive in the logical level such as:- disk part of C, D, A, local drive to store and install all the types of program files and database files related to the operating system. If the user deletes any files from the specific drive where the operating system installed then the operating system misbehaves after deleting any important file it can be turned off after a few seconds.
