Study Notes
Computer Architecture Overview
- A typical desktop computer consists of modular components, allowing for easy upgrades and replacements.
- Primary components include the Microprocessor (CPU), Memory, Storage devices, Input devices, Output devices, and Buses.
Component Functions
- Input Devices: Allow users to enter data (e.g., keyboard, mouse, scanner).
- Output Devices: Produce outputs from CPU data (e.g., monitor, printer).
- Buses: Physical connections for data transfer, can be integrated into the motherboard or external cables (e.g., IDE, ATA).
- Memory: Fast chip-based storage that holds binary instructions, calculation results, and provides data to the CPU.
- Storage Devices: Slow but large capacity systems for long-term data storage (e.g., floppy drives, HDDs, CD/DVD).
- CPU: Acts as the "brain," manages information flow, communications with memory and I/O devices, and performs computations.
Central Processing Unit (CPU)
- Speed is measured in MHz or GHz; notable models as of 2019 include:
- Intel i9: 8 cores, 16 threads
- Intel Xeon D: 18 cores, 36 threads
- AMD RYZEN Threadripper 2: 32 cores, 64 threads
- Comprised of four sections:
- Control Unit: Regulates information flow.
- ALU (Arithmetic Logic Unit): Handles logic and calculations.
- Registers: Fast storage for instructions and data.
- Cache (L1 and L2): Stores frequently accessed data; L1 is primary and L2 secondary.
Modern CPU Architecture
- Multi-core CPUs allow for parallel processing, where each core functions independently with its own components, supporting multitasking.
- Hyper-Threading: Intel’s technology that simulates two logical processors per physical core to optimize resource use, improving processing speed when one core is resource-stalled.
System on Chip (SoC)
- SoCs integrate various components of traditional PC architecture into a single chip, simplifying design and improving efficiency compared to conventional architectures that use separate components.
