Study Notes

Operating System Functions

Operating systems (OS) manage the interaction between applications and hardware.
OS control hardware access through device drivers.
Device drivers are installed automatically when a device is installed.
The OS assigns system resources and installs drivers using the plug-and-play (PnP) process.
The registry, a database containing computer information, updates after each new device installation.
OS manage files and folders, organizing them in a hierarchical structure.
Files are blocks of related data grouped into directories.
Directories can be nested, creating subdirectories.
Windows calls directories "folders" and subdirectories "subfolders."
OS provide two types of user interfaces: command-line interface (CLI) and graphical user interface (GUI).
OS manage applications, locating them and loading them into the computer's RAM.

Types of Operating Systems

Multi-user: Two or more users can work with programs and devices simultaneously with separate accounts.
Multitasking: The computer can operate multiple applications at the same time.
Safe Mode with Networking allows Windows to start with networking support, but limited functionality.
Safe Mode with Command Prompt loads the command prompt instead of the GUI.
Last Known Good Configuration loads the most recent successful Windows settings.
Windows 8 and 10 Startup Modes: Hold Shift and select restart to access startup settings. This will display the "Choose an Option" screen.

Windows Installation

There are three major desktop operating systems: Microsoft Windows, Apple macOS, and Linux.
Before installing an OS, a storage media device must be selected and prepared.
The primary partition contains the operating system files.
The active partition stores and boots the operating system.
Extended partitions contain logical drives.

32-bit vs. 64-bit Architectures

Data Handling: 32-bit processors handle data in 32-bit chunks, while 64-bit processors handle data in 64-bit chunks.
Memory Addressing: 32-bit systems can address up to 4 GB of RAM, while 64-bit systems can address up to 16 exabytes of RAM (practical limits are lower).
Performance: 64-bit processors are generally more powerful, especially for demanding tasks.
Compatibility: 64-bit processors can run both 32-bit and 64-bit applications, while 32-bit systems can only run 32-bit applications.
Security: 64-bit systems offer enhanced security features like hardware-based data execution prevention (DEP) and kernel patch protection.

Clean Installation of an Operating System

A clean install is necessary when a computer is passed between users, the OS is corrupt, or the primary hard drive is replaced.
The OS setup is the initial installation and booting of the operating system.
External media like DVDs or USB drives are typically used to install operating systems.
