Study Notes
Information and Resource Protection
- The Operating System (OS) safeguards information and resources, ensuring they are utilized correctly.
- It prevents unauthorized access and incorrect usage of system resources.
Accounting
- The OS maintains records of system functionality and logs errors encountered during operations.
- This accounting feature helps in troubleshooting and improving system performance.
Need for Operating System
- Hardware is essentially complex machinery that requires management for optimal operation.
- An Operating System acts like a secretary, executing commands from the user.
- Users issue requests to the OS, which decides how, what, and when to perform these tasks.
Responsibilities of Operating System
- Recognizes and configures peripheral devices connected to the computer.
- Manages input and output operations for effective data processing.
- Organizes and maintains files and folders within the file system.
- Loads and executes applications, enabling user interaction with software.
- Facilitates data transfer to and from the hard disk for storage and retrieval.
- Allocates and manages system memory among various applications and processes.
- Monitors system errors and activates alerts to inform users of issues.
- Enhances system security by implementing measures to protect against threats.
- Provides a communication interface for software applications to interact with hardware components.
Operating System Overview
- An operating system (OS) serves as an interface between users and hardware.
- It enhances user interaction by facilitating access in a user-friendly language.
- The OS aims for optimal system performance by managing resources like CPU and memory.
- Security measures ensure only authorized users can access the system through valid accounts.
- Concepts like virtual memory allow the OS to simulate additional memory beyond physical limits.
Components of Operating Systems: Shell and Kernel
- An operating system has two main components: the Shell and the Kernel.
- The Shell provides user interaction, while the Kernel manages hardware communication.
The Shell
- Functions as an Interpreter, receiving commands from users.
- Responsible for translating user instructions into machine language.
- Passes the translated commands to the Kernel for execution.
The Kernel
- The Kernel is the core part of the OS, essential for direct hardware communication.
- Manages resources such as CPU allocation and memory distribution.
- Acts as a bridge between user applications and hardware, ensuring efficient operation.
- Key responsibilities involve memory management and device management, optimizing system functionality.
