Any computer system must have an operating system (OS), which serves a variety of purposes. It is the foundation of the entire computer experience and is essential to allowing users to interact with their hardware and applications.

1. What is the purpose of an OS (operating system)?
Any computer system must have an operating system (OS), which serves a variety of purposes.
It is the foundation of the entire computer experience and is essential to allowing users to
interact with their hardware and applications. Hence Mr. Service Academy provides Smartphone
repairing courses in Chennai.
The following are an operating system's main goals:
Hardware Administration:
Hardware resources including the CPU (central processing unit), memory, storage, input/output,
and network interfaces are all managed by an operating system. It makes sure that these
resources are distributed effectively among different software applications and that there are no
conflicts between them.
Interface User:
An intuitive user interface is offered by operating systems for computer-human communication.
This covers command-line interfaces for more experienced users as well as graphical user
interfaces (GUIs) like Windows and macOS. Users can communicate with apps and the system
itself through the user interface.
Handling Procedures:
Processes (independent programs or tasks) are created, scheduled, and terminated by
operating systems (OSes). They control multitasking, enabling the operation of several
programs at once, and make sure they don't conflict with one another.
File System Administration:
Operating systems control files and directories, provide a framework for data management,
storage, and retrieval. They manage access control, file permissions, and data security and
integrity.
Device Drivers:
To help software and hardware components communicate with one another, operating systems
come with device drivers. The compatibility and correct operation of peripherals like printers,
keyboards, and graphics cards depend heavily on these drivers.
Memory Handling:

2. The operating system (OS) manages memory resources, making sure that each process or
application has the memory it requires without going overboard. To maximize memory utilization,
it also manages virtual memory.
Secure access management:
In order to safeguard the system and data against viruses, malware, and unwanted access,
operating systems (OSes) include security features such user authentication, data encryption,
and access control.
Networking:
A lot of operating systems come with network capabilities that let computers connect to other
devices and the internet. They oversee data transmission, settings, and network protocols.
Error Resolution:
In order to identify and fix problems and flaws in both hardware and software, operating systems
(OSes) include error handling techniques. They could report errors for diagnostic purposes or
show error warnings to users.
Resource Distribution:
Operating systems (OSes) maintain resource balance to prevent any one application from
taking up all of the system's resources, giving all processes that are operating a fair and
effective environment.
An operating system's main function is to serve as a bridge between hardware and software,
enabling effective and seamless communication between the two. In order to guarantee a
computer system operates steadily and securely, it controls resources, abstracts the complexity
of hardware, and offers an intuitive interface. Using a computer would be far more difficult and
inefficient without an operating system.
I strongly recommend checking with the Mr. Service Academy before enrolling in any courses.
