History of Operating System:
An operating system (OS) is a software program that manages computer hardware and software resources and provides common services for computer programs. The history of operating systems is closely tied to the development of computers and their applications.
The earliest electronic computers in the 1940s and 1950s did not have operating systems. Instead, they were programmed directly in machine language, which was time-consuming and error-prone. In the 1950s, the development of higher-level programming languages made it possible to write programs in a more natural way and led to the development of early operating systems.
In the late 1950s and early 1960s, operating systems were developed to manage multiple users on mainframe computers. These systems, such as IBM's OS/360, provided a way for multiple users to share the same computer resources, and introduced the concept of virtual memory.
In the 1970s, the development of microprocessors led to the development of smaller computers, and the rise of personal computing. The first operating system for personal computers was CP/M, which was developed by Digital Research. However, CP/M was soon overtaken by Microsoft's MS-DOS, which was released in 1981 and became the dominant operating system for personal computers.
In the 1980s and 1990s, a number of graphical user interfaces were developed, which made it easier for users to interact with their computers. Apple's Macintosh operating system, which was released in 1984, was one of the first operating systems to use a graphical user interface. Microsoft's Windows operating system, which was released in 1985, also introduced a graphical user interface and quickly became the dominant operating system for personal computers.
In the 1990s and 2000s, the development of the internet led to the rise of networked computing, and the development of server operating systems such as Linux and Windows Server. These operating systems were designed to manage multiple users and applications on networked computers, and provided the foundation for many of the internet services that we use today.
Today, operating systems continue to evolve, with new features and capabilities being added to meet the needs of users and applications. The development of open-source operating systems, such as Linux, has also helped to promote the use of free and open-source software, and has contributed to the growth of the software development community.
Introduction to operating system:
An operating system is a program that manages a computer’s hardware. It also provides a basis for application programs and acts as an intermediary between the computer user and the computer hardware. An amazing aspect of operating systems is how they vary in accomplishing these tasks. Operating system is the only software which provides the user access to the hardware of the computer. Without operating system it is hard to access even hard disk of the computer for the user. If a user wants to access the hard drive of computer it is necessary to write a program to access the drive and then another piece of code for allocating and deallocating the space respectively. In short it is difficult for user to divide and monitor the resources which are allocated to different processes in the computer. For this, it is a operating system which is a resource allocator, provide security to the system and give the user-friendly graphical interface which helps the user to recognise what task is computing by the system.
Let’s talk about the types of operating systems on the basis of their purposes and uses:
Types of operating system:
The types of operating system on the basis of their use are following as:
• Batch operating system.
• Server operating system.
• Mobile operating system.
• Real-time operating system.
• Embedded operating system.
• Distributed operating system.
• Personal computer operating system.
Above are the types of the operating systems, let discuss all of them one by one.
Batch operating system:
The batch operating system is the type of the operating system which is used for processing or executing the tasks which are similar to each other. It doesn’t need any interactive user for handling or operating it.
The batch operating system simply takes all the instructions or jobs from the user or other systems and sort them in the groups of similar tasks and then starts to execute them sequentially.
There are some key factures of the batch operating system which are following as:
• Non-interactive.
• Scheduled Execution.
• Job control language.
• Minimal user interaction.
• Commonly used for repetitive jobs.

Introduction to Ubuntu OS:
Ubuntu is a popular Linux-based operating system that was introduced in 2004 by Canonical Ltd, a UK-based software company. The name "Ubuntu" is derived from a South African philosophy of community and togetherness, which reflects the company's vision of creating a user-friendly and collaborative computing environment.
The first version of Ubuntu, Ubuntu 4.10, was released in October 2004 and was based on the Debian Linux distribution. It was designed to be a free and open-source alternative to proprietary operating systems such as Microsoft Windows and Mac OS X, and was intended to be easy to use and highly customizable.
One of the key features of Ubuntu is its focus on community development and collaboration. The operating system is based on the Linux kernel and uses a range of open-source software tools and libraries, many of which are developed and maintained by a global community of developers.
Ubuntu also includes its own software center, which provides a range of free and open-source software applications that can be installed with a single click. This makes it easy for users to discover and install new software, and provides a centralized location for software developers to distribute their applications.
Over the years, Ubuntu has become a popular choice for both personal and professional use, and has gained a reputation for stability, security, and ease of use. Canonical has also expanded its offerings to include a range of cloud-based services, such as Ubuntu Server and Ubuntu Core, which are designed for use in cloud computing and internet of things (IoT) applications.
Today, Ubuntu is available in a range of different versions, including long-term support (LTS) releases that are supported for up to five years, and specialized versions for use in education, scientific research, and other fields. Its popularity and commitment to open-source software have helped to establish Ubuntu as one of the leading Linux-based operating systems in the world.
History:
Ubuntu is a free and open-source operating system that is based on Debian, another popular Linux distribution. The project was started in 2004 by South African entrepreneur Mark Shuttleworth, who founded Canonical Ltd. to support the development of Ubuntu. The name "Ubuntu" is derived from an African concept that means "humanity towards others."
The initial release of Ubuntu, version 4.10, was released in October 2004. It was based on Debian and used the GNOME desktop environment, and was designed to be easy to use and install. The release was well-received, and subsequent releases of Ubuntu continued to gain popularity among Linux users.
One of the key features of Ubuntu is its commitment to providing a user-friendly experience for both new and experienced users. Ubuntu includes a range of pre-installed software, such as the LibreOffice suite, the Firefox web browser, and the GIMP image editor. It also includes a software centre that makes it easy to install additional software, and a system updater that keeps the system up to date with the latest security patches and bug fixes.
Another important feature of Ubuntu is its commitment to open-source software. Ubuntu includes only free and open-source software by default, and the source code for all of the included software is available for users to review and modify. This makes Ubuntu a popular choice among developers and other users who value the ability to modify and customize their operating system.
Since its initial release, Ubuntu has continued to evolve and improve. Canonical has released a new version of Ubuntu every six months, with long-term support (LTS) releases every two years. The LTS releases are supported for five years, providing a stable and reliable platform for users who value stability and security.

Management of processes:
In an operating system, any kind of program or application running in the system is a process. The executing program is basically called as a process. Managing the process is the key feature of any operating system as it assures that each process run smoothly and does not cause any interference with any other already running process.
Following are the detailed features of the management of the process:
• Process Creation.
• Process Scheduling.
• Process States.
• Context Switching.
We will, now further elaborate each term one by one:
Process Creation:
When a new process started, the OS creates the block of memory which is called as the PCB (Process control block), in order to store the information about that process. That PCB actually contains the all information about the priority level, state and memory needs.
Process creation is a process by which a new process created from an existing process. It is a primary function of the operating systems. By this OS enables to perform multiple operations simultaneously.
When a new process is created the OS allocates the necessary resources to the newly formed process these resources include the stack space, hard drive space, some allocation on the registers and some file descriptors etc. Then the new process inherits certain attributes from the parent process which included the PPID (Parent process Identity) but the PID (Process Identity) of any new child process is unique, current working directory is also included.
The process creation involves many operations which are following as:
• Memory allocation for new process.
• Process context.
• Duplication of parent process.
• Setting the PC (Program Counter).
• Arguments to process.
• Initiation of new process.
Memory allocation for new process:
The OS allocates the block of memory stack to the newly created process in order to store its code, instructions, data and stack.
Process context:
In this state the OS initiate the process context which include PID, PPID, PS and process priority.
Duplication of parent process:
At this phase the OS duplicates or copies the image of the parent process that mask over the new process’s memory space, it also includes the instruction set same as the parent process, data and stack.
Setting PC:
The operating system sets the PC (program counter) of the new process to the address of main function of that process.
Arguments to process:
The OS passes the required arguments to the newly created process, such as command-line arguments.
Initiation of new process:
In the final stage the operating system sets the new process state to the “Ready state” and then adds that process to the “Ready Queue” where it waits for the CPU to executes its instructions and then after the execution the process goes to the “Terminate” state.
Process Scheduling:
When once, the OS created the process via PCB it schedules the process to execute on the processor. The scheduling algorithm used by the operating system, generally priority queue or the Round Robin algorithm, determines which process will run and which process will run next, it also depends on the current workload of the processor.
The process scheduling is done by the operating system via using some of the following algorithms in order to schedule the particular processes on the basis of their resource allocation and there priority to execute.
• First-Come, First-Served (FCFS).
• Shortest Job First (SJF).
• Round Robin (RR).
• Priority-Based Scheduling.
Process States:
In OS, a process can be at any state, it depends upon the current status, resource allocation, instruction, data and priority.
The operating system manages the different states of the process the most common states are following as:
• New.
• Ready.
• Running.
• Blocked.
• Terminated.
New:
This is the initial state of a process that has been created, but has not yet been admitted to the ready queue.
Ready:
A process that has been admitted to the ready queue and is waiting for CPU time to execute is said to be in the ready state.
Running:
A process that is currently executing on the CPU is said to be in the running state.
Blocked:
A process that is waiting for an event or a resource, such as input/output or a lock, is said to be in the blocked state.
Terminated:
A process that has finished executing and has been terminated is said to be in the terminated state.
Context Switching:
Context switching is a mechanism that enables an operating system to switch between different processes or threads on a CPU quickly and efficiently. When a running process is interrupted or blocked, the operating system saves the process's current state, including the values of CPU registers and other information about the process, to memory. The operating system then selects the next process to run and loads its state from memory into the CPU registers, allowing the process to continue executing from where it left off.
Context switching can occur in several situations, including when a process is preempted by a higher-priority process, when a process blocks on I/O or other system resources, or when a process voluntarily yields the CPU to another process.
Context switching has several benefits and drawbacks:
Benefits:
Allows the operating system to run multiple processes simultaneously, enabling efficient use of CPU resources.
Enables preemption of low-priority processes by high-priority processes, ensuring that critical tasks are completed in a timely manner.
Enables a process to relinquish the CPU voluntarily to prevent long delays caused by blocking I/O operations.
Drawbacks:
Context switching can be a resource-intensive process, requiring significant CPU time and memory bandwidth to save and restore process states.
Frequent context switching can degrade overall system performance by introducing additional overhead and reducing the amount of time available for executing processes.
Context switching can introduce additional complexity into the operating system, making it more difficult to debug and maintain.
Memory:
Ubuntu, like other modern operating systems, uses various techniques for managing memory efficiently. Memory management is a crucial part of the operating system's role, as it determines how processes access and use memory resources.
Here are some of the following ways Ubuntu manages memory:
• Virtual Memory.
• Memory Allocation.
• Shared Memory.
• Memory Compression.
• Memory Swapping.
Virtual Memory:
Ubuntu uses virtual memory to manage memory resources. Virtual memory is a technique that allows the operating system to use a portion of the hard drive as an extension of physical memory. When the RAM is full, the operating system swaps out less frequently used data to the hard drive, freeing up RAM for more immediate use.
Memory Allocation:
Ubuntu allocates memory to processes as they request it. The operating system uses a memory allocation algorithm that ensures efficient use of available memory while preventing processes from exceeding their allocated memory limits.
Shared Memory:
Ubuntu supports shared memory, which allows multiple processes to share memory resources. This is useful for communication between processes or for sharing large data sets.
Memory Compression:
Ubuntu uses memory compression to reduce the amount of memory that a process uses. Memory compression works by compressing inactive memory pages and storing them in RAM, freeing up physical memory for more immediate use.
Memory Swapping:
Ubuntu uses a memory swapping mechanism to move inactive processes out of RAM and onto the hard drive, freeing up RAM for other processes. This technique is useful for managing memory resources when the available RAM is limited.
Disk:
Ubuntu, like any other modern operating system, provides several tools and techniques for managing disks and file systems.
Here are the following ways by which Ubuntu OS done its disk management:
• Disk Partitioning.
• Disk Encryption.
• Disk Quotas.
• Disk Clean-up.
• Disk Mounting.
• File System Check.
Disk Partitioning:
Ubuntu allows users to partition disks during the installation process. This allows the user to divide a physical disk into smaller logical partitions that can be used to store different types of data. The partitions can be formatted with different file systems such as ext4, NTFS, or FAT32, depending on the user's needs.
Commands for Disk Partitioning:
Following Linux commands for complete disk partitioning:
1. Sudo fdisk -1
2. Sudo fdisk [disk path]
3. Pressing “m” list of available commands.
4. For creating the partition, we use command “n”.
5. For logical partition, choose “l”.
6. For primary, choose “p”.
7. “L” command for displaying the list of HEX codes.
8. Formating a partition: sudo mkfs
9. Sudo mkfs.ext4 [partition path]
Disk Encryption:
Ubuntu supports disk encryption using the LUKS (Linux Unified Key Setup) encryption system. LUKS provides full disk encryption, making it a secure way to store sensitive data on the disk.
Commands for Disk Encryption:
By using following commands of Linux we can done our disk encryption in the Ubuntu operating system:
1. sudo apt install cryptsetup
2. sudo cryptsetup –verbose –verify-passphrase luksFormat /dev/sdb1
3. sudo cryptsetup luksOpen /dev/sdb1 sdb1
4. sudo fdisk -l
5. sudo mkfs.ext4 /dev/mapper/sdb1
6. sudo tune2fs -m 0 /dev/mapper/sdb1
7. sudo mkdir /mnt/encrypted
8. sudo mount /dev/mapper/sdb1 /mnt/encrypted
9. touch /mnt/encrypted/testfilename.txt
10. sudo cryptsetup luksClose sdb1
Disk Quotas:
Ubuntu allows users to set disk quotas for users or groups. This limits the amount of disk space a user or group can use on a particular partition.
Commands for Disk Quotas:
Following are the Linux commands for disk quotas:
1. -cug /file system
2. -avug
3. quota
4. quota [-u [User]] [-g[Group]] [-v | -q]
5. quota.user
6. quota.group
7. /etc/filesystems
Disk Clean-up:
Ubuntu provides various tools for cleaning up disk space. For example, the Disk Usage Analyzer tool allows users to identify and delete large files or directories that are no longer needed. The system also includes the apt-get command for cleaning up unused packages.
Commands for Disk Clean-up:
There are commands of Linux for cleaning up the disk:
1. rm [filename]
2. rmdir [directory name]
Disk Mounting:
Ubuntu automatically mounts external disks when they are connected to the system. Users can also manually mount and unmount disks using the mount and unmount commands. This allows users to access data stored on external disks or USB drives.
Commands for Disk Mounting:
These are the Linux commands for disk mounting in Linux:
1. unmount /media/nfs
2. unmount /media/iso
3. unmount /media/usb
4. unmount /dev/cdrom
5. unmount /dev/fd0
6. fuser -m /media/usb
File System Check:
Ubuntu provides a tool called fsck for checking the file system's integrity and repairing any errors. This tool checks the file system's metadata and data blocks and ensures that they are consistent.
Input and output (I/O):
Input/output (I/O) operations refer to the transfer of data between the computer and its peripherals, such as disks, network adapters, or printers. Ubuntu, like any other modern operating system, provides several ways to manage I/O operations.
Here are some following ways that how Ubuntu OS manages I/O:
• Device Drivers.
• Buffering.
• Caching.
• I/O Scheduling.
• Disk and File System Optimization.
• File System Monitoring.
Device Drivers:
Ubuntu provides device drivers for a wide range of devices such as hard disks, USB drives, printers, and network adapters. These drivers are used to communicate with the hardware and provide a standard interface for I/O operations.
Buffering:
Ubuntu uses buffering to speed up I/O operations. When data is read or written, it is first stored in a buffer in memory. The operating system then transfers the data to or from the device in larger chunks, which can be more efficient than transferring data one byte at a time.
Caching:
Ubuntu uses caching to speed up frequently accessed data. When data is read from a device, it is stored in a cache in memory. When the same data is accessed again, it can be read from the cache instead of the device, which can be much faster.
I/O Scheduling:
Ubuntu provides various I/O scheduling algorithms that determine the order in which I/O operations are performed. These algorithms aim to optimize the use of the disk and reduce latency for I/O operations.
Disk and File System Optimization:
Ubuntu provides tools for optimizing disk and file system performance. For example, the system includes the tune2fs command for adjusting file system parameters, such as the maximum number of open files or the amount of reserved space for the root user.
File System Monitoring:
Ubuntu provides tools for monitoring file system usage and identifying performance issues. For example, the iostat command can be used to monitor disk I/O activity, and the lsof command can be used to identify processes that are accessing specific files.
