• - Hardware: Physical components such as computers, servers, routers, and storage devices that process and store data.
• - Software: Programs and applications that facilitate data processing and manipulation.
• - Data: Raw facts, figures, and information that are collected, stored, and processed by the system.
• - Procedures: Sets of instructions and guidelines that govern how the system operates, including data entry, processing, and security protocols.
• - People: Users, stakeholders, and professionals who interact with the system, perform tasks, and make decisions based on the information generated by the system. People play a critical role in inputting data, interpreting results, and ensuring the system is utilized effectively and ethically.

2. System Software: System software refers to a collection of programs that manage and control the operations of a computer system. It includes the following types of programs:

• - Operating Systems: Software that provides a platform for running other applications and manages hardware resources.
• - Device Drivers: Programs that facilitate communication between hardware devices and the operating system.
• - Utilities: Tools that assist in system maintenance, file management, data backup, and security.

3. General-Purpose Applications, Specialized Applications, and Apps:

• - General-Purpose Applications: These are versatile software programs designed to perform a wide range of tasks, such as word processing (Microsoft Word), spreadsheets (Microsoft Excel), presentation creation (Microsoft PowerPoint), and email clients (Microsoft Outlook).
• - Specialized Applications: These are software programs tailored for specific industries or purposes, such as accounting software (QuickBooks), graphic design tools (Adobe Photoshop), engineering software (AutoCAD), or medical record systems (Epic).
• - Apps: Apps, short for applications, are software programs designed for mobile devices, offering specific functionalities or services. They can range from games and social media platforms to productivity tools and e-commerce applications.

4. Types of Computers:

• - Personal Computers (PCs): The most common type, including desktops, laptops, and tablets, designed for individual use.
• - Workstations: High-performance computers used for specialized tasks like graphic design, video editing, and scientific simulations.
• - Servers: Computers dedicated to providing services, resources, and data storage to multiple users or other computers in a network.
• - Mainframes: Powerful computers capable of processing vast amounts of data and supporting large-scale enterprise operations.
• - Supercomputers: Extremely high-performance machines used for complex scientific calculations, weather forecasting, and simulations.

5. Connectivity and Computer Network:

• - Connectivity refers to the ability of devices to establish a connection and communicate with each other.
• - A computer network is a collection of interconnected devices (computers, servers, routers, etc.) that can exchange data and share resources. Networks can be local (LAN) or wide area (WAN), and can be wired or wireless.

6. The Internet and the Web:

• - The Internet is a global network of interconnected computer networks, enabling communication and data exchange between devices worldwide.
• - The World Wide Web (Web) is a collection of websites and web pages accessible through the Internet. It is a system of information linked together by hyperlinks and accessed through web browsers.

7. Cloud Computing, Wireless Revolution, and IoT:

• - Cloud Computing: It refers to the delivery of computing services (such as storage, servers, and software) over the Internet, allowing users to access resources remotely.
• - Wireless Revolution: The advancement of wireless technologies that enable wireless communication and connectivity, including Wi-Fi, Bluetooth, and mobile networks.
• - Internet of Things (IoT): It refers to the network of physical devices (such as sensors, appliances, and vehicles) connected to the internet, enabling them to collect and exchange data.

• 8. Information System: An information system is a combination of people, processes, technologies, and resources that collect, store, process, and distribute information within an organization.
