Study Notes
IFT 103: OS Architecture - Module Overview
- The module will cover the basics of computer hardware.
- Learning objectives include understanding why hardware knowledge is necessary, what computer hardware is, the main parts of a computer, how computers work electrically, how computers keep time, multithreading, and future trends in computer hardware.
Module Learning Objectives
-
Why learn about hardware?: IT professionals need a strong understanding of hardware to identify and fix problems, optimize performance, and make informed decisions about system upgrades.
-
What is computer hardware?: Physical components of a computer system that are visible and touchable.
-
Main parts of a computer: Processor (CPU), Memory (RAM), Storage Devices, Cooling Systems, Motherboard, Graphics Processing Unit (GPU), Power Supply Unit (PSU), Input/Output Devices, Ports/Connectors
-
How does it all electrically work?: Electricity represents binary values in digital systems – high voltage represents 1, low voltage represents 0. Transistors act as switches controlling electricity based on input signals. Logic gates perform logical operations on input signals and combine to create complex circuits.
-
How does a computer keep time?: Computers use a crystal with a constant frequency (the clock) embedded in the CPU. Clock speed, measured in GHz, is a critical factor influencing performance, affecting how many cycles the processor performs per second.
-
What is Multithreading?: A technique where a single CPU core can handle multiple tasks simultaneously. Threads split instructions for concurrent processing.
-
Future Trends in Computer Hardware: Miniaturization and portability (smaller, more efficient devices), Quantum Computing (using quantum mechanics for complex calculations), AI and hardware acceleration (specialized hardware for AI tasks), IoT (connecting everyday objects to the internet), 6G connectivity (increased device density and communication speed), Biometric security (advanced authentication methods like fingerprint scanners), Flexible and Foldable Displays (innovative display technology), Edge Computing (processing data closer to the source), 3D Printing and Additive Manufacturing, Biocompatible Computing, Sustainable Computing, and Holographic Displays and Augmented Reality (AR).
Computer Hardware
-
Processor (CPU):
- The brain of the computer
- Executes instructions and performs calculations
- Controls overall computer operations
- Has different cores for parallel processing
- Clock speed influences performance of the CPU
- The fetch-decode-execute cycles describe the CPU’s operations
-
Memory (RAM):
- Stores data actively used by the CPU.
- Provides quick access for active programs.
- Temporary storage, data is lost when power is off. Volatile.
- Data is stored in memory cells, organized in a grid with unique addresses, called random access.
- RAM access speeds are important for responsive operation.
- Virtual memory uses part of the hard drive as an extension of RAM when actual RAM fills up.
-
Graphics Processing Unit (GPU):
- Specializes in graphical tasks.
- Handles graphical rendering (images, videos, etc.), frequently used in gaming.
- Employs parallel processing (performing multiple tasks at once)
- Uses shader cores for calculations related to graphics rendering. Stages in the rendering pipeline include vertex processing, geometry processing, rasterization, fragment processing, and pixel output.
- Texturing and shading effects add realism to rendered scenes
-
Motherboard:
- Connects and integrates various computer hardware components. The central hub.
- Components Include:
- CPU socket
- RAM slots
- Expansion slots (PCIe x16, PCI Express x1, etc)
- Chipsets (Northbridge and Southbridge)
- Power connectors
- Input/output ports (USB, audio, Ethernet, HDMI)
- BIOS
- Clock generator
- Power regulation
-
Storage Devices:
- Hard Disk Drives (HDD): Stores data magnetically on spinning disks.
- Solid State Drives (SSD): Uses flash memory, offering faster speeds than HDDs.
- Examples of Storage Devices Include CDROM, Pen drive, and floppy discs
-
Power Supply Unit (PSU): Supplies power to all computer components.
-
Cooling Systems: Prevent component overheating. Use fans, heatsinks, and liquid cooling.
-
Input Devices: Devices for user input (keyboards, mouse, touchpad, etc).
-
Output Devices: Display or provide user information (monitor, printer, speakers, etc).
-
Ports and Connectors Enables communication between the computer and external devices, different standards serve different needs. (USB, HDMI, Ethernet, etc.).
-
Electricity and Computers: Uses voltage levels to represent binary values (1 and 0). Transistors act as switches controlling the flow of electrons based on inputs. Logic gates combine to perform operations.
How does a Computer Keep Time?
- Computers use a crystal that oscillates at a constant rate, setting the clock speed for operations, measured in Hertz (Hz).
Multithreading
- Multithreading is a technique allowing a single core to handle multiple tasks simultaneously.
Future Trends
- Future hardware trends include miniaturization, specialized hardware for AI tasks, and connectivity innovations (6G). Biometric security, Flexible and Foldable Displays, and computing at the edge will also shape the future.
