Study Notes
Editing in Media
- Computers streamline editing processes for movies, videos, songs, and audio, eliminating manual cuts.
- CGI (Computer-Generated Imagery) is standard in high-budget films, utilizing computers and server farms for effect creation.
- Media manipulation involves software like Adobe Photoshop for altering images.
Recording and Playback
- Computers aid in recording audio tracks and allow selective playback of individual tracks.
- Creation of multimedia content such as 3D animations and techno audio tracks can be achieved using computers.
- 3D printers can produce tangible products from virtual 3D models.
Smart Devices
- Modern Smart TVs, DVD players, and DVRs incorporate computing capabilities for internet connectivity and app usage.
Robotics
- Computers are essential in controlling robotic systems, determining operation speed, part placement, and problem detection.
- Robots utilize input data to learn and adapt to changing conditions.
Simulations
- Complex problem-solving, such as weather predictions, relies on computers to analyze numerous variables efficiently.
- Product simulations allow adjustments before developing new products based on simulated real-world performance.
Historical Computing Devices
- Electro-mechanical devices like Hollerith's Punch Card Machine and Jacquard's Loom used punched cards for data control.
- Significant early electronic devices include ABC (Atanasoff-Berry Computer) and ENIAC, pioneers in digital computing.
Early Computer Generations (1951-1958)
- First-generation computers utilized vacuum tubes and magnetic drums, with processing capabilities of 1,000 instructions per second.
- UNIVAC I was recognized as the first commercial business computer.
Display Technology
- CRT monitors exhibit a limited number of characters, are bulky, and consume high power.
- Flat-panel displays are lighter and more energy-efficient, categorized into emissive (e.g., LED) and non-emissive (e.g., LCD) types.
Printers
- Printers are classified into impact and non-impact types.
- Impact printers, such as dot matrix printers, produce characters through mechanical striking, suitable for bulk printing but are noisy.
Primary Memory
- Primary memory holds active data and instructions, characterized by volatility; data is lost when power is off.
- RAM (Random Access Memory) allows random access to data but is temporary, while ROM (Read-Only Memory) is non-volatile.
Secondary Memory
- Secondary memory is slower yet serves as long-term storage, retaining data indefinitely without power.
- Examples include disks, CD-ROMs, and DVDs.
RAM Types
- RAM can be static (SRAM), retaining data with power, or dynamic (DRAM), which needs refreshing.
- RAM is volatile, and data is erased when power is switched off.
Malware Types
- Spyware: Collects user information covertly, hard to detect.
- Zombie Programs: Hijack computers for malicious purposes, such as attacks on other networks.
- Phishing: Deceptive messages lure users into sharing personal data.
- Spam: Unsolicited emails often spreading malware.
- Adware: Displays ads automatically with potential for bundled malware.
- Ransomware: Locks access to a computer, demanding payment to regain control.
Malware Distribution Methods
- Common ways malware spreads include social networks, pirated software, and removable media, requiring user interaction to execute.
