Computer Systems

Computer systems form the foundational infrastructure of modern information technology, comprising interconnected hardware and software components that enable digital computation and communication.

Core Components

Hardware Elements

• Processing Units: CPU and GPU processors
• Memory Systems: RAM for active processing and storage-devices for persistent data
• Input/Output Devices: Interface components for human-computer-interaction
• Network Interfaces: Hardware enabling network-protocols communication

Software Layer

• Operating Systems: OS managing hardware resources
• System Software: device-drivers and system-utilities
• Application Software: user-applications for specific tasks
• Middleware: software-interfaces bridging different system components

System Architecture

Architectural Patterns

1. Client-Server: Distribution of processing between service providers and consumers
2. Distributed Systems: distributed-computing spanning multiple machines
3. Embedded Systems: embedded-computing purpose-built configurations
4. Cloud Systems: cloud-computing virtualized infrastructures

System Organization
