Study Notes

System Overview

A system in computing refers to a computer and its dependencies, including all components needed for technical processes to function.
A computer system consists of hardware, software, and users interacting with the device.

Computer System Components

Computer Hardware: Includes devices such as desktops, laptops, mobile devices, cables, CPU, keyboard, and storage.
Computer Software: Comprises operating systems and applications either pre-installed or downloaded.

Important Elements of Computer Systems

Central Processing Unit (CPU): The main control center located on the motherboard, responsible for instructing programs and processing input. Components include:
- Clock: Transmits pulses to keep time.
- Control Unit: Directs operations and instructions.
- Arithmetic Logic Unit (ALU): Performs calculations.
- Registers: Store small amounts of data temporarily.
- Cached Memory: Speeds up repetitive operations.

Peripheral Devices

Peripheral devices extend a computer's functionality and can be internal or external. Examples include:
- Storage Devices: External hard drives, disk drives, and USB drives.
- Networking Devices: Modems, routers, hubs, and switches.
- Display Devices: Monitors and projectors.
- Input Devices: Headphones, microphones, SD cards, HDMI cords, and chargers.

Computer Operating Systems

Essential for all major devices including computers, mobile phones, and servers.
Directs hardware operations, manages resources like memory, and oversees application performance.
Installed during setup or via external storage media containing the OS.
Operating System Statistics (2021):
- Windows: 89% (Desktop/Laptop)
- macOS: 8% (Desktop/Laptop)
- Linux-based: 1.9% (Desktop/Laptop)
- Android: 78.1% (Mobile)
- iOS: 20.7% (Mobile)
- Other Mobile OS: 1%

Other Types of Systems

Enterprise Software Systems: Facilitate various organizational functions including resource planning, human resources, customer management, and web production.
ERP Systems: Serve manufacturing and retail industries, handling tasks like service management, supply chain management, vendor management, inventory costs, and invoicing.
HRM Systems: Manage employee data, applicant information, company policies, and payroll systems.
