Study Notes

Data Processing and ICT Trends

Data processing includes outsourcing work to lower-cost countries, resulting in workforce reduction as fewer employees handle the same tasks.
Increased access to information via the Internet enhances communication, education, and social interaction opportunities but can also lead to feelings of isolation.
ICT tools, like digital cameras and editing software, empower individuals with disabilities to access content that was previously unavailable.
VoIP, email, messaging, and video conferencing offer cost savings over traditional communication methods, promoting efficiency.
The processing speed of modern computers can reach 100 million instructions per second.

Types of Computers

Supercomputers are the fastest and most accurate, solving complex calculations.
Hybrid computers combine characteristics of analog and digital types, aiding in specific scientific and engineering problems.
Minicomputers provide a cost-effective alternative for processes between PCs and mainframes, although they are less common today.

Computer Hardware Components

Input hardware collects and converts data for processing purposes, while output hardware displays or presents processed information.
Memory types include RAM (volatile, temporary storage) and ROM (non-volatile, permanent instructions).
Specialized devices like MICR, OMR, and OCR aid in reading and processing unique forms of input.

Terminal Types

Dumb terminals function solely for input and output.
Smart terminals perform limited processing and feature both input and output capabilities.
