Study Notes

Process Synchronization and System Calls

Process synchronization ensures that multiple processes work without causing interference.
The fork() system call duplicates a process, creating a child process from a parent process.

System Logs and OS Functions

System logs document system events and errors for troubleshooting and analysis.
An operating system manages memory, hardware, and software resources.

Operating System Types

Ubuntu is recognized as a server operating system, designed to manage network resources and services.
Android is commonly used on mobile devices, offering user-friendly interfaces.

User Interfaces

The graphical user interface (GUI) utilizes icons, buttons, and windows, facilitating easier user interactions.
Command line interface (CLI) requires users to type commands into a terminal.

Signals and Process Management

A synchronous signal, such as a program error signal, occurs in response to process actions or states.
SIGKILL is an asynchronous signal that forcefully terminates a process without cleanup.
User-defined signal handlers allow custom responses to specific signals within processes.

Process and Storage Management

Key functions of process management include creating, scheduling, and terminating processes.
Secondary storage is managed for long-term data retention, with hard drives serving as primary examples.

Networking and Security Management

Network management includes monitoring traffic and connections within the operating system.
Security management protects against unauthorized access to system resources.

Operating System Features

MacOS is optimized for Apple hardware, ensuring better performance on its devices.
Kali Linux is a specialized OS focused on security and penetration testing.

System Calls and User Input Management

System calls are essential for processes to request services from the operating system kernel.
I/O device management oversees control and operation of hardware components like printers and keyboards.

Notable Characteristics

Different operating systems have unique characteristics; for instance, Windows 11 is proprietary, while Ubuntu and Android are open-source.
The default shell in macOS is ZSH, while most Unix-like systems use BASH as the default shell.

Process Signal Types

SIGINT is generated by user actions like pressing CTRL+C, resulting in a process termination.
No process can handle a SIGKILL signal, illustrating its function as a forced termination command.

Miscellaneous Functions

The command interpreter translates user commands into executable actions.
File management includes storage and access control to ensure organized data handling.
