SLO 1.5.2

Operating Software (Operating System - OS):

Purpose: The operating system is the core software that manages and controls all the hardware and software resources of a computer system.

Functions: It provides services for running applications, managing memory, handling input and output, and controlling peripheral devices.

Examples: Windows, macOS, Linux, Unix, Android, iOS, etc.

Device Drivers:

Purpose: Device drivers are software components that allow the operating system to communicate with and control hardware devices like printers, graphics cards, and keyboards.

Functions: They provide a bridge between the hardware and the operating system, enabling the OS to send commands and receive data from the hardware.

Examples: Printer drivers, graphics card drivers, sound card drivers, etc.

Utility Programs:

Purpose: Utility programs are software tools designed to perform specific tasks related to system maintenance, optimization, and management.

Functions: They help users manage files, troubleshoot problems, maintain system performance, and enhance security.

Examples: Disk cleanup tools, antivirus software, file compression utilities, backup software, disk defragmenters, etc.

Language Processors:

Purpose: Language processors are software tools used for translating and executing high-level programming languages.

Functions: They convert human-readable code into machine code that the computer's CPU can understand and execute.

Examples: Compilers, interpreters, and assemblers. For example, Java & C# as compiler and Python as interpreter

SLO 1.5.1

System Software:

Purpose:

System software is like the backbone of your computer. It's designed to manage and control the hardware components of your computer system.

Its primary purpose is to enable the computer hardware to function smoothly and provide a platform for running application software.

Examples:

Operating System: This is the main system software that manages your computer's hardware and allows you to run other programs. Common examples include Windows, macOS, and Linux.

Device Drivers: These are special programs that help your operating system communicate with specific hardware devices, like printers or graphics cards.

User Interface:

System software often doesn't have a direct user interface that you see and use. Instead, it runs in the background to make your computer work.

Interaction with Hardware:

System software directly interacts with your computer's hardware, such as the CPU, memory, storage devices, and peripherals.

Key Functions:

Manages memory and resources.

Handles file management and storage.

Provides security and user access control.

Facilitates communication between hardware components.

Application Software:

Purpose:

Application software is what you use to perform specific tasks or get work done on your computer.

Its primary purpose is to meet the needs and preferences of users by providing various functions and tools.

Examples:

Word Processors: Programs like Microsoft Word or Google Docs for creating and editing documents.

Graphic Design Software: Such as Adobe Photoshop for editing images and graphics.

Web Browsers: Like Google Chrome or Mozilla Firefox for surfing the internet.

Video Games: Fun applications like Minecraft or Fortnite for entertainment.

User Interface:

Application software has a user-friendly interface that you interact with directly. This is where you do your work or have fun.

Interaction with Hardware:

Application software interacts with system software to use hardware resources, but it doesn't control the hardware directly.

Key Functions:

Provides tools for specific tasks (e.g., word processing, gaming, designing).

Offers a user interface for user interaction.

Utilizes system resources through the operating system.

SLO 1.4.1

Differentiate between data and information

Data:

Definition: Data refers to raw, unprocessed facts and figures. It can be in the form of numbers, text, images, sounds, or any other representation.

Nature: Data is often unorganized, lacks context, and doesn't convey meaning on its own. It's like the pieces of a puzzle that need to be put together.

Example: In computer science, data could be a series of numbers stored in a file, a list of names, or the color values of pixels in an image.

Purpose: Data serves as the foundation for generating information. It needs to be processed and analyzed to extract meaningful insights.

Information:

Definition: Information is data that has been processed, structured, or organized in a way that gives it context, meaning, and relevance.

Nature: Information is data that has been transformed to provide knowledge, answers to specific questions, or support decision-making.

Example: In computer science, information can be the result of processing data, such as a statistical summary of a dataset, a report generated from data analysis, or a graph representing trends.

Purpose: Information is the end goal of processing data. It's what we use to make informed decisions, draw conclusions, or communicate knowledge effectively.
