Operating Systems Lecture 5

The operating system's primary role is to manage the computer's resources (hardware and software) and provide a platform for applications to run smoothly. It simplifies complex hardware interaction, making it easier for programmers and users to interact with the system.

The OS gives applications a way to communicate with the hardware, creating a consistent and simplified interface. It also manages the hardware resources efficiently to ensure optimal performance for all applications.

By providing a standardized API, the OS allows developers focus on application logic without needing to know the specifics of every hardware component.

The kernel is the OS's core component. It manages crucial OS functions, interacts directly with hardware, and resides in memory for quick access.

The OS manages the processor efficiently by allocating time slots to different applications. This ensures all running programs receive their necessary processing power.

The OS is responsible for dividing memory space for individual programs and making sure they don't interfere with each other. It also optimizes memory usage by managing different levels of memory (RAM, cache, etc.)

The OS manages peripherals like printers, keyboards, and storage devices. It provides a consistent way for applications to interact with these devices.

The OS is in charge of managing files and folders on the storage device. It includes operations like creating, deleting, and accessing data.

Operating systems that allow multiple users to access and utilize the computer's resources concurrently.

A type of operating system designed for personal computers, allowing a single user to interact with multiple programs simultaneously.

A family of operating systems that are known for their stability, security, and open-source nature, widely used in servers and embedded systems.

Operating systems tailored for specific devices with limited hardware resources, commonly found in smartphones, smart appliances, and industrial equipment.

A family of operating systems developed by Microsoft, well-known for their user-friendly interfaces and widespread use on personal computers.

The purpose of something, or the need or reason for which it is done. It's the 'why' behind an action, idea, or event.

A set of steps or actions taken in order to achieve a particular outcome. It often involves a series of tasks or stages to reach a desired result.

The ability to influence or produce a particular effect or result. It refers to the power or capacity to bring about change or have an impact.

To think about something carefully and consider its different aspects before forming an opinion or making a decision. It involves weighing the pros and cons and exploring various options.

The act of finding something that will satisfy a particular need or desire. It involves searching or exploring for something that fits a specific purpose or criterion.

A collection of directories, subdirectories, and files organized in a logical order. The OS manages it through indexing of filenames and their disk location, ensuring efficient file retrieval.

A software that acts as an intermediary between applications and devices. It manages the communication and ensures smooth interaction between them. It controls how devices interact with the computer.

The OS simplifies the interaction between applications and hardware, shielding developers from low-level complexities. It provides a standardized interface for all applications, enabling them to access hardware resources without detailed knowledge.

The way users communicate with the computer. It can be either command-line based, where users type commands, or graphical, using icons, menus, and a pointing device.

Designed to manage resources for embedded systems like robots, machinery, and scientific instruments. It prioritizes precise timing for operations and resource optimization.

A single user can perform one task at a time. Examples include MS-DOS with its command line interface.

A single user can work on multiple tasks simultaneously. The OS effectively manages the resources to allow multiple programs to run concurrently.

Allows multiple users to access and share resources on a single computer simultaneously. It manages user accounts, permissions, and resource allocation.
