Blossoming Hope.... In shadows deep, where darkness weaves its tale, A flicker emerges, a whisper, a frail sail. Hope, a luminescent bloom in the night, A beacon that guides with its soft, steadfast light. In the garden of dreams, where doubts may entwine, Hope sprouts like wildflowers, resilient, divine. Petals unfurl with a promise untold, A story of strength, a future to behold. Through tempests that rage, hope stands as a shield, A fortress of solace, a force unrevealed. In the echoes of sorrow, its melody plays, A song of endurance through life's shifting maze. Ephemeral, yet potent, as morning's first ray, Hope dances with dawn, chasing shadows away. Each heartbeat, a rhythm, a testament clear, That in hope's tender embrace, there's nothing to fear. A phoenix ascending from ashes of plight, Hope paints the horizon in hues pure and bright. With wings of resilience, it soars to the sky, A symbol of courage, refusing to die. In the tapestry woven with threads of de...

What is an operating system?
Have you
ever wondered how a user and a system communicate with one another? How does
system hardware interpret a user's commands? So, the operating system is the
solution to these questions. Hardware is nothing more than a piece of
constructed equipment, and it requires an interface to bridge the gap between
hardware and the user.
When you
turn on a computer for the first time, the operating system is the most crucial
application that is loaded. An operating system facilitates communication
between a user and a computer system. It converts the user's instructions from
high-level language to machine language, which a computer understands. It
serves as a bridge between the user and the computer hardware, providing the
environment needed to run various programmes efficiently.

The Evolution of Operating Systems
•
The
first computer, the Z1, was built between 1936 and 1938. Unfortunately, there
was no operating system on this machine.
· In 1956, twenty years later, the
first operating system was created.
· Bell Labs began developing UNIX, the
first multitasking operating system, in the 1960s.
· The apple series was first released
in 1977. The first disc operating system was Apple Dos 3.3.
•
In
1981, Microsoft purchased 86 – DOS software from a Seattle startup and created
the first operating system known as DOS.
•
When
MS-DOS and GUI, a graphical environment, were combined in 1985, the most
renowned Microsoft windows were born.
Operating System Features
•
Processor Management: An operating system controls the
processor's operation by allocating various workloads to it and ensuring that
each process is given adequate time to complete its tasks.
•
Memory Management: An operating system controls the
allocation and deallocation of memory to multiple processes, ensuring that
memory assigned to one process is not consumed by another.
•
Device Management: A variety of input and output
devices are available. The operation of these input-output devices is
controlled by an operating system. It takes requests from these devices,
completes a job, and then interacts with the requesting process.
•
File Management: An operating system keeps track of
information on file creation, deletion, transfer, copy, and storage in a
systematic manner. It also safeguards the data contained in these files, as
well as the file directory structure, by preventing unwanted access.
•
Data Integrity and Confidentiality: The operating system employs a
number of measures to ensure the integrity and confidentiality of user data. To
secure user data, some security procedures are employed.

Batch Operating System
Batch OS is
the first operating system for computers from the second generation. This
operating system has no direct interaction with the computer. Instead, an
operator gathers jobs that are related and arranges them into a batch, which is
then completed one by one according to the first-come, first-serve concept.
Distributed Operating System
A
distributed operating system is a new innovation in computer technology that is
rapidly gaining traction all around the world. A distributed operating system
connects several machines over a single communication channel. Loosely
connected systems are separate computers that have their own memory unit and
CPU.
System
processes come in a variety of sizes and can execute a variety of roles. The
main advantage of such an operating system is that it allows a user to view
files that are not on his system but are on another linked machine.
Additionally, the systems connected to this network have remote access.
Multitasking Operating System
The
multitasking OS is also known as the time-sharing operating system since each job
is allotted a certain amount of time to ensure that everything runs smoothly.
This system allows a huge number of users access, and each user receives the
same amount of CPU time as they would in a single system. The tasks are
assigned by a single user or by several users.
A quantum is
the amount of time allocated to finish one job, and after that time is up, the
system shifts to the next task.
Operating System for Networks
The systems
that operate on a server and control all networking tasks are known as network
operating systems. They enable the sharing of data, programmes, printers,
security, and other networking capabilities over a small network of computers,
such as a LAN or any other private network. All users in a network operating
system are aware of each other's setups, which is why network operating systems
are also known as tightly connected systems.
Real-Time Operating System
Real-time
operating systems are designed to support real-time systems. These operating
systems are beneficial in situations where a large number of events occur in a
short period of time or when strict deadlines must be met, such as real-time
simulations.
Operating System for Mobile Devices
An operating
system for smartphones, tablets, and PDAs is known as a mobile OS. It's a
platform that allows other apps to operate on mobile devices.
