Study Notes
Functions of an Operating System
- Handles the creation, scheduling, and termination of processes
- Manages physical and virtual memory in the system, including RAM and cache memory
- Oversees file system management, including file creation, deletion, and organization on different storage devices
- Manages files on different storage devices, including hard drives and SSDs
- Maintains basic file attributes like naming, permissions, and hierarchy of directories
File System Management
- Uses a hierarchical folder (or directory) structure to organize files
- Starts with a root directory, with subsequent directories (or sub-directories) branching out from there
- Allows for systematic and organized storage and retrieval of files
- Both Linux and Windows use hierarchical folder structures, but with differing conventions, naming, and organization
Types of Operating Systems
- Multitasking/Time-sharing OS: executes multiple jobs by switching between them, making it seem like they are all executing simultaneously
- Real-time OS: responds to input immediately, used in systems with tight constraints on response time
- Distributed OS: manages a group of independent computers, making them appear as a single computer
- Embedded OS: used in embedded computer systems like washing machines and ATMs
Examples of Operating Systems
- Desktop OSs: Windows, macOS, Linux distributions (like Ubuntu, Fedora), UNIX
- Mobile OSs: Android, iOS, Windows Phone, BlackBerry OS
- Server OSs: Windows Server, Linux distributions optimized for server use, UNIX
- Embedded Systems: Real-time operating systems like RTLinux, VxWorks, and Windows IoT
Components of an OS
- Kernel: core component of an OS, manages operations of the computer and hardware
- Shell: interface between user and kernel, receives commands from users and executes kernel's functions
- Utilities: help in system maintenance and performance enhancement
Importance of Utility Software
- Ensures optimized performance by fixing issues and cleaning unnecessary files
- Enhances security by protecting computers from threats that could compromise data and privacy
- Prevents data loss by creating backups and allowing for recovery
- Improves organization by helping to manage files and folders
Types of Utility Software
- Disk Defragmenters: rearrange fragmented data on hard drives, making them work more efficiently
- System Utilities: provide tools to manage and maintain a computer's performance
- Virus Scanners & Antimalware Tools: detect and remove malicious software from a computer
- Backup & Recovery Utilities: create copies of data and system files, allowing for system recovery in case of failure
- File Compression Utilities: reduce the size of files or folders, making them easier to transfer or store
- Network Utilities: analyze and monitor networks, diagnose network problems, and measure network performance
