Design Principles of Industry 4.0
- Key design principles include interoperability, information transparency, technical assistance, and decentralized decision-making.
Computer System Overview
- A computer system processes input data, executes programs, and stores output results for future use.
- The four main functions are input (e.g., keyboard), process (e.g., calculations), output (e.g., display), and storage (e.g., hard drives).
Von Neumann Architecture
- The model consists of a CPU for execution, memory for immediate data use, storage for future data, input devices for data entry, and output devices for result display.
- Modern computer systems follow Von Neumann architecture.
Computer Hardware Components
- Motherboard: Contains the chipset, BIOS, and expansion slots; connects all other hardware components.
- CPU: Central processing unit requiring cooling for function.
- RAM: Random Access Memory that stores code and data for immediate processing.
- Storage Devices: Include hard disk drives (HDD), solid-state drives (SSD), and removable drives for data archiving.
- Peripheral/Expansion Cards: Enhance functionality such as graphics and sound, important for gaming or intensive processing.
Team Activities and Discussions
- Teams are encouraged to discuss digital transformation examples, successful technology adoption, and the future landscape of work.
- Activities include identifying hardware components, discussing impact on processes, and exploring real-world applications of technologies.
Future Directions
- Industry 5.0 focuses on human-machine collaboration for sustainable innovation and environmentally friendly production.
- Emphasizes the need for integration of human creativity with advanced technology in production processes.### Computer Hardware Components
- Peripheral cards connect to the motherboard and enhance functionality, such as sound and network cards.
- Identification labels on peripheral cards help find documentation and specifications online.
- Peripherals are categorized as input, output, or input/output devices.
- The chassis protects hardware and provides convenient access to motherboard connectors.
- The power supply unit (PSU) delivers power to the motherboard and computer system.
Common Motherboard I/O Connectors
- Key motherboard connectors include CPU socket, chipset, DIMM/RAM slots, PCIe slots for GPUs, M.2 connectors for SSDs, and SATA ports for HDDs.
- Front panel connectors, USB headers (2.x and 3.x), and various power connectors are also essential.
Common Motherboard Rear I/O Connectors
- Common rear connectors include HDMI, DisplayPort, USB A (2.0 and 3.0), USB C, RJ-45 (LAN), WiFi, optical S/PDIF out, and audio I/O ports.
Software Overview
- Software consists of instructions for computers, divided into:
- Application Software: Specific tasks (e.g., spreadsheets, database management).
- System Software: Interfaces for application software, including operating systems (OS) and device drivers.
Operating System Functions
- Manages hardware and provides communication between hardware and application software.
- Key functions include process management, memory management, file management, and device management.
- Ensures security and allows for simultaneous program execution.
Data Representation
- Computers use binary (1s and 0s) to represent information.
- The smallest unit of data is a bit; 8 bits form a byte.
- Higher data units include kilobytes (kB), megabytes (MB), gigabytes (GB), and terabytes (TB), with different definitions based on context (speed vs. storage).
User Interfaces
- Types of user interfaces include graphical user interfaces (GUI), command line interfaces, touch interfaces, voice interfaces, and natural-language interfaces.
Hardware Compatibility and Specifications
- Hardware specifications describe the characteristics and compatibility of components with operating systems.
- A Hardware Compatibility List (HCL) aids in identifying which hardware works with specific operating systems.
Plug and Play (PnP)
- Plug and Play devices allow automatic hardware detection without user intervention, typically using generic device drivers (e.g., USB devices).
PC Assembly and Testing
- The assembly process includes testing individual components like the motherboard, PSU, CPU, and RAM.
- Simulation software for building PCs helps understand compatibility and assembly procedures.
- Documentation of the assembly process through screenshots is essential for learning.### Computer System Technologies Overview
- A diverse range of computer hardware and operating systems exists today.
- Component testing methods include functionality tests and performance tests using specialized software.
Component Testing
- Functionality Test: Assess if a part operates correctly in a known working system.
- Performance Test: Use software to evaluate the speed and efficiency of components.
- Burn-in Testing: Stress-testing components before deployment using tests like PassMark BurnInTest.
Laptop Specifics
- Laptops contain similar hardware to desktops but often have integrated components on the motherboard.
- Many parts are custom-built, limiting cross-compatibility with other laptop models.
- Refurbishing laptops is generally more complex than desktops.
Operating System Installation Steps
- Access BIOS settings when booting the computer.
- Set the boot preference to DVD or USB.
- Choose the clean installation option for the OS.
- Enter the license key if necessary.
- Select the disk to install the OS.
Sustainability and Green IT
- Sustainability in IT aims to minimize environmental impacts during the lifecycle of technology.
- Objectives include creating energy-efficient devices, reducing harmful materials, promoting recycling, and encouraging reuse of tech.
Goals of Green IT
- Improve design for energy efficiency and recyclability.
- Minimize the use of rare metals and toxic chemicals.
- Advocate for proper e-waste recycling towards environmentally friendly practices.
Data and Resource Virtualization
- Virtualization creates software representations of hardware, allowing multiple applications to operate independently on shared resources.
-
Types of Virtualization:
- Server Virtualization: Partitioning a physical OS into virtual machines.
- Desktop Virtualization: Creating virtual desktop systems accessed remotely.
- Storage Virtualization: Merging physical storage into a single pool.
- Network Virtualization: Splitting bandwidth into independent channels.
Hypervisors
- Type 1 Hypervisor: Bare-metal, runs directly on hardware; used in enterprise settings.
- Type 2 Hypervisor: Hosted on an operating system; typically for smaller server environments.
Desktop Virtualization
- Separates desktop environments from physical machines, allowing centralized data management.
- Supports testing and development while isolating sensitive applications within virtual machines.
- Reduces maintenance needs on physical PCs and simplifies management through a single desktop image.
Types of Desktop Virtualizations
- Presentation Virtualization: Centralized server manages applications, function as a terminal; less efficient and secure.
- Application Virtualization: Applications are delivered on demand, encapsulating them from the host OS.
- Hosted Virtual Desktop: Virtual desktop environments run on remote servers, allowing access from any device.
Learning and Skills Development
- Students are encouraged to explore BIOS settings, discuss virtualization benefits, and participate in skills-building activities to understand OS and cloud computing concepts.
