Introduction To Mobile Operating System.

Obiagwu Francis
Mobile operating system OS, as the name implies is a foundational software platform that ensures the  effective and smooth running of an hardware device.For all applications to run seamlessly,an OS is needed.
A Mobile operating system OS is not necessarily considered an application simply because it manages or excecutes other applications but because it is a critical system software component.

BENEFITS OF AN OPERATING SYSTEM OS

Being the bedrock of our Mobile devices, Operating system OS comes with a while lots of benefits to user
 
It offers user-friendly interface which allows for easy navigation, simple gestures etc.

For high quality photos and videos, Operating system OS includes mobile advanced camera features such as HRD.

With Operating system OS on our Mobile device, connections with various accessories such as Bluetooth devices, headphones and peripheral such as input devices is granted access.

Operating system OS supports location-based services, allowing users gain knowledge geographically.

It allows mobile users to easily connect their mobile devices to Bluetooth-enabled speakers for wireless audio Playback and also for accessing external storage devices.

FUNCTIONS OF AN OPERATING SYSTEM OS

Hardware resources management

Process management

Memory management

File system management

Device management

User interface

Security

Networking

Error handling and recovery

ARCHITECTURAL COMPONENT OF AN OPERATING SYSTEM OS

These components includes key elements that collectively enables the operating system OS to manage hardware system, executes applications and provides user-interface.Such components includes;

KERNEL:

It provides essential services and manages system resources to ensure the proper functioning of the entire system.Its core functions includes;

It manages hardware resources by allocating to running processes to ensure optimal performance and for sharing among multiple processors.

Maintenance process control block (PCBs) to store information about each process, including its state, priority and resources usage.

Manages system memory by allocating memory to processes, tracks memory usage and handles memory swapping between RAM and secondary storage.

Controls communication between software and hardware devices.

Provides an interface for applications to interact with the underlying system through system calls.

Implements security mechanisms suchas; user authentication, firewall configuration etc, to protect the system and it's resources from unauthorized access, malware and other security threat. 

DEVICE DRIVERS:

These components are responsible for facilitating communication between the Operating System OS and hardware devices attached to a system device.Its core functions includes;

Enables the Operating system OS to interact with various hardware component.

Provides the necessary functionality for controlling and managing hardware devices.

Abstract hardware specific details a present a standardized interface to the Operating system OS and applications.

Interacts closely with the Operating System OS kernel to access system resources and handle device-related tasks.

SYSTEM LIBRARIES

These components are responsible for collecting reusable code modules that provides common functions and services to applications running on an Operating system OS.Its core functions includes;

Promotes code reuse by providing reusable component that can be shared among multiple applications.

Provides a set of functions and macro specified by the C Programming Language Standard.

Exposes Application Programming Interface (APIs) that defines the interface between applications and the underlying Operating system OS.

They encapsulate common operations and provides convenient abstractions for developers.

USER INTERFACE (UI)

These encompasses all components and features that enables users to communicate and Interact with the system.Its core functions includes;

User graphical elements (such as; windows, icons, buttons, menus and dialogue boxes) to present information and receive input from users

With the aid of Command Line Interface (CLI) which allows user to interact with the system by typing command into a text based terminal or console.

Touchscreen interface which allow user to interact with devices by directly touching the screen with their finger or a stylus.

Voice User Interface (VUI) suchas Virtual assistance like Siri, Alexia, and Google assistant enables user to interact with a system using spoken command or natural language input.

Gesture recognition interface which detects and interpret human gestures such as hand movement, finger gestures, or body motion to control devices or interact with software applications

FILE SYSTEM

This is a subsystem responsible for organizing and managing data stored on storage devices.Its core functions includes;

Its organizes data in hierarchical directory structure allowing for logical organization and easy navigation

Responsible for file naming within the file system for identification.

Provides information about files and govern access control and file management operations.

Supports various file operations, including creation, deletion, renaming, copying, moving, reading, and writing files.

Manages the allocation of storage space on storage devices 

SECURITY SUBSYSTEM

The security subsystem of an Operating System OS is responsible for implementing and enforcing security policies, mechanisms and controls, to protect the system and its resources.Its core functions includes;

Handles user authentication.

Enforces access control policies to regulate which users or processes are allowed to access, modify or delete system resources

Implement encryption techniques to protect sensitive data stored on storage devices.

Some Operating System OS incorporate firewall functionalities into the security subsystem to monitor and filter network traffic, controlling the flow of data between the system and external networks. 

SYSTEM UTILITIES

These are software tools or programs provided by an Operating System OS to perform various system administration, maintenance, and troubleshooting task.Its core functions includes;

Disk management utilities which allows user to partition, format and merge storage devices 

Files management utilities which help users organize, search and manipulate giles and directories on the file system.

Backup and recovery utilities which enables user to create backup of data and system configuration.

Performance monitoring utilities which provides real-time monitoring, historical data analysis and alerts for performance anomalies.

Network utilities which provides tools for IP address configuration, network interface management, ping testing, trace route, network scanning and pocket caption.

System information utilities provides detailed information about the hardware and software configuration of the system.

System update utilities which ensures that the installation of software updates, patches system remains up-to-date with the latest software releases and security patches.
