CAO107 module 7

Kernel

The central part of an operating system managing system resources and providing low-level services like process and memory management.

Shell

The user interface of an OS offering a CLI or GUI for user interaction with the system.

System Libraries

Libraries providing common functions for applications like file management and network communication.

Device Drivers

Software enabling OS communication with hardware devices, acting as intermediaries.

File System

Manages data storage, defines file structure, and provides file operations like creation and deletion.

Batch Operating Systems

Group similar jobs for processing without direct user interaction.

Multi-Programming Systems

Execute multiple programs concurrently to enhance throughput.

Multi-Processing Systems

Utilize multiple CPUs for improved performance.

Time-Sharing Operating Systems

Allow multiple users simultaneous access by dividing CPU time.

Real-Time Operating Systems (RTOS)

Ensure guaranteed response time, suitable for time-sensitive applications.

Booting and Startup Management

Functions related to system booting and startup processes.

Memory Management

Manages system memory allocation and usage.

Process Management

Controls processes and their execution within the system.

Device Management

Manages hardware devices and their interaction with the OS.

Security Management

Ensures system security through various mechanisms.

Input/Output (I/O) Management

Manages input and output operations within the system.

Hardware-Software Interface

Acts as an interface between hardware and software for effective communication.

Resource Management

Allocates system resources efficiently among programs and processes.

Abstraction and Virtualization

Provides a layer of abstraction for hardware access and enables component cohesion.

Standardization and Compatibility

Establishes standards for hardware and software compatibility.

Multitasking and Concurrency

Manages multiple programs concurrently and coordinates resource access.

64-bit operating systems

Operating systems optimized for 64-bit architectures, offering significant performance and memory advantages for demanding applications, multitasking, and memory-intensive workloads.

32-bit compatibility

Support provided by modern 64-bit operating systems for running 32-bit applications or maintaining 32-bit subsystems to ensure backward compatibility with older or legacy software and hardware.
