Study Notes
Introduction to Computing Fundamentals
- A computer comprises hardware, software (operating and application), peripheral devices, and users.
- Computers are classified by size: supercomputers, mainframes, minicomputers, and microcomputers (PCs, laptops, smartphones).
- Classification by use includes general-purpose (flexible functions) and special-purpose (limited tasks, e.g., IoT devices).
Functions of Computing
- Input: Methods to enter data (typing, touchscreen, voice commands).
- Processing: Converting input into usable data (central processing units facilitate this).
- Output: Displaying results via devices like monitors and printers.
- Storage: Saving data on various mediums (internal/external hard drives, cloud storage).
Benefits of Computing
- Reduces human errors, enhances communication, performs complex calculations, and improves editing capabilities.
- Digital data storage reduces physical space requirements, offering permanent access.
Common Computing Devices and Their Platforms
- Stationary Devices: Workstations, servers, and gaming consoles found in fixed locations, supporting various operating systems.
- Mobile Devices: Laptops, tablets, and smartphones, typically more portable, running on popular OSs like Windows, iOS, and Android.
- IoT Devices: Integrate sensors and software for communication through networks (e.g., smart appliances, security systems).
Notational Systems
- Decimal (Base 10): Standard counting system using digits 0-9.
- Binary (Base 2): Utilizes only 0 and 1 to represent data, essential for computer processing.
- Hexadecimal (Base 16): Combines digits and letters (0-9, A-F) for compact data representation, frequently used in networking.
Data Types and Character Encoding
- Data Types: Include characters, strings, integers, floats, and Boolean values enhancing data handling in software.
- ASCII: Represents characters in computing (originally 7-bit, later 8-bit).
- Unicode: Expands character support (UTF-8 most prevalent online).
Operating Systems Overview
- An OS manages hardware, provides user interfaces, and executes software applications.
- Evolved through generations, from early batch systems to modern multitasking environments.
- Major OS history includes Linux (open-source, significant market share), Windows (dominant consumer OS), macOS (based on Unix), and ChromeOS (browser-centric).
Single-Stream Batch Operating Systems
- Characteristics include batch processing of jobs, sequential execution, automation, and operational efficiency without user interaction.
Internal and External Components
- Internal components (RAM, hard drives, CPU) are crucial for functionality, whereas external components connect through standardized ports.
- Peripheral Devices: Add functionality like input (mouse, keyboard), output (printers), and storage (external drives).
Input Devices Comparison
- Keyboards: Primary input method through USB or PS/2.
- Mouse: Widely used for navigation; connects via USB or Bluetooth.
- Touchpads: Built into laptops, functioning like a mouse.
- Other Devices: Cameras (digital imaging), joysticks (gaming), and trackballs (alternative navigation).
Hard Drives Characteristics
- Internal storage devices (like hard drives) hold digital data permanently, facilitating data access and performance.### Computer Storage Devices
- RAM (Random-Access Memory): Volatile memory; data is lost when power is turned off.
- Hard Disk Drive (HDD): Internal storage device, operates using magnetic platters; can be internal or external.
- HDD Sizes:
- 2.5” HDDs are found in notebooks with smaller capacities.
- 3.5” HDDs are meant for desktops, with capacities ranging from 500GB to several TB.
- Types of HDD Connections:
- SATA (Serial Advanced Technology Attachment): Most common in modern computers.
- PATA (Parallel Advanced Technology Attachment): Supported by many motherboards but slower than SATA.
- HDD Performance Factors:
- Spin Speed (RPM): Influences performance; common speeds include 5400 RPM and 7200 RPM.
- Access Time: Fast HDDs have access times typically between 5 to 10 ms.
