1.1 Definitions

Operating system (OS): A program that controls the execution of application programs, acting as an interface between applications and computer hardware.
OS function: Manages a computer system's internal workings, including memory, processors, devices, and file systems.

1.2 Operating System History

Operating Systems evolve over time.
Evolution is driven by the invention of new technologies, adding features and increasing power.

1.3 Mainframe System

A large computer, less so than supercomputers, with more processing power than many other classes of computers (minicomputers, servers, workstations, personal computers).
Often used as servers.
The term "mainframe" originates from the large cabinet housing the CPU and primary memory in early computers.

1.4 Desktop System

A personal computer designed to fit on a typical office desk.
Houses the physical hardware and input devices (monitor, keyboard, mouse) for user interaction.
Popular desktop operating systems include Macintosh, Microsoft Windows, and Linux. macOS, frequently associated with Apple devices, is often considered user-friendly but may be a relatively more expensive option compared to others.

1.5 Multiprocessing System

Utilizing two or more Central Processing Units (CPUs) within a single computer system.
Enables the simultaneous execution of multiple tasks improving efficiency.

1.6 Distributed System

A system with components on different networked computers.
Components communicate and coordinate by passing messages to one another.
These components create an impression of being a single system.
Social media platforms are examples of distributed systems.

1.7 Cluster System

A group of servers and resources that mimic a single system.
Facilitates high availability, load balancing, and parallelism.
Created by merging multiple computer systems.

1.8 Real-Time System

Systems requiring timely responses to meet specified deadlines.
Real-time constraints dictate reaction times.
Found in devices like washing machines, printers, in vehicles, imaging systems, etc.

1.9 Handheld System

Operating systems found in smartphones and tablets.
Often called Personal Digital Assistants (PDAs).
Typically characterized by high processing power and embedded sensors (e.g., cameras, GPS).

1.10 Virtual Machine (VM)

A virtual environment acting as a virtual computer system with its CPU, memory, networking interface, and storage—all established on a physical hardware machine.
Allow several different operating systems to operate on a single device, like a Linux distribution on a Mac OS machine.
User experience nearly identical to that of a physical machine running the selected operating system.

1.11 Live CD

A complete bootable operating system image stored on a CD, DVD, or similar optical media.
Runs directly from the optical disc into computer memory—does not require a hard disk.

1.12 USB Bootable

A USB drive used to boot up a computer system during installation of an OS.
Command-line-based tools are necessary for creating a USB boot.
Windows versions before 7 may have limitations regarding this process.

1.13 BIOS vs UEFI

UEFI (Unified Extensible Firmware Interface) modernizes the older BIOS (Basic Input/Output System).
Provides enhanced features like quicker boot times, elevated security, larger disk support, and graphical user interfaces.
BIOS, the older system, relies on 16-bit coding with limited options.
Modern systems usually include UEFI.
