A program that manages computer hardware and software resources, providing an interface between applications and the hardware.

Manages the computer's resources, like memory, processors, devices, and files. It also runs applications.

Students will describe different operating systems, functions, and user interfaces.

Students will explore processes managed by an operating system.

Students will demonstrate the use of operating systems in different system constraints.

The evolution of operating systems over time, showing changes and improvements.

The parts of a computer used by an operating system to deliver its services - memory, processors, devices, and file systems

The different parts of a computer system and their organizations.

The progression of operating systems from early mainframe systems to modern mobile and AI-integrated systems.

A powerful, large computer often used as a server, characterized by more processing power than minicomputers, servers, and workstations.

A personal computer designed for use on a desk, typically smaller than a mainframe.

The ability for multiple users to access and use the same files across a network.

The ability to access data and applications through mobile devices like smartphones.

The incorporation of artificial intelligence features into operating systems.

Early systems focused on batch processing, lack of user-friendliness and continuous execution of programs with interrupts.

The development and evolution of operating systems designed to support networked file sharing and mobile access.

Early computer systems lacked operating systems, requiring users to manually input instructions or punch cards. This was very complex and inefficient.

An early OS approach where multiple jobs are grouped together and processed sequentially. The operator loads a batch of programs, and the OS executes them one by one.

An OS feature allowing multiple programs to run seemingly concurrently in memory, by switching between them. The OS manages the CPU's time to give each program a short turn.

The first OS allowed multiple programs and more efficient management compared to manual input.

Modern operating systems provide a graphic user interface (GUI) allowing users to interact with the computer via visual elements.

A language that uses numbers (0 and 1) to represent instructions for the computer, common in very early systems.

The ability of a system to handle increasing workloads by adding more resources like computers.

Distributing resources like memory, processing power, and storage across multiple computers in a system.

Distributing tasks across multiple computers can make applications faster by allowing each computer to focus on a specific task.

Ability of a system to continue working even if some computers fail, because tasks are spread out.

Managing multiple computers and their communication in a distributed system is difficult.

A single compromised computer can affect the entire distributed system, making it vulnerable to attacks.

Distributed systems rely heavily on the network for communication, any issues with the network can impact the entire system.

Implementing and maintaining distributed systems can be expensive due to the resources required, including hardware, software, and skilled personnel.

A group of servers and resources that act like a single system, offering high availability, load balancing, and parallel processing.

Improved performance due to parallel processing, better fault tolerance (one node fails, others take over), greater scalability (adding new nodes), reliability, automatic recovery from failures, and enhanced resource availability.

Higher cost due to expensive hardware, multiple servers required, complex monitoring and maintenance.

A system that must respond to events within a specified time constraint, regardless of workload.

A mobile device with an embedded operating system, like smartphones and tablets.

A virtual environment simulating a real computer with its own resources like CPU, memory, and storage, running on a physical computer.

Allows running multiple operating systems simultaneously on a single computer, providing flexibility and resource optimization.

To run different operating systems or applications on one computer, test software in a safe environment, or isolate programs for security.

A software-based emulation of a physical computer, allowing you to run different operating systems simultaneously on a single machine.

A bootable CD containing a complete operating system that runs directly from the CD-ROM, without needing to install it on the hard drive.

A USB drive that contains an operating system, enabling you to boot a computer from it and install the operating system.

UEFI (Unified Extensible Firmware Interface) is a newer and more advanced standard that replaces the older BIOS (Basic Input/Output System) in modern computers.

UEFI provides faster boot times, better security, larger disk support, and a graphical user interface, compared to BIOS.

The older BIOS system, known for slower boot times, limited features, and a text-based interface.

UEFI offers advantages over BIOS such as faster boot times, better security, larger disk support, and a graphical user interface.

The older BIOS system offers a basic text-based interface, slower boot times, and limited features.
