Study Notes

Hybrid Machines and Their Functionality

Hybrid machines efficiently tackle specialized problems in science and engineering.
They feature equipment that converts analog voltages to digital and vice versa.

Classification of Computers by Capacity

Supercomputers:
- Renowned for speed and accuracy, solving complex mathematical computations.
- Execute trillions of instructions per second measured in FLOPS (Floating Point Operations Per Second).
Mainframe Computers:
- Large and powerful, designed for high-volume data handling.
- Serve multiple users simultaneously, often referred to as "big iron."
- Commonly used in business environments for resource access.
Minicomputers:
- General-purpose devices, less expensive than mainframes.
- Processing power above personal computers but below mainframes.
- Popular in the late 1960s; diminished due to the rise of personal computers.
Microcomputers:
- Smallest and most affordable computers, commonly known as PCs.
- Limited processing power and memory compared to larger systems.
- Composed of typical components like a keyboard, display screen, and a communication link.

Types of Terminals

Dumb Terminals: Input data and receive information only.
Smart Terminals: Capable of both input and output; possess limited processing capabilities.
Intelligent Terminals: Fully functional microcomputers with communication links.

Input Hardware Components

Direct-Entry Devices: Include various pointing devices such as mouses, trackballs, and joysticks for user input.
Light Pen and Digitizing Tablets: Enable direct drawing on screens and sketching images digitally.
Pen-Based Systems: Use stylus to capture handwriting and marks.
Scanning Devices: Translate images and text into data for computer understanding.
Bar Code Readers: Convert bar code symbols into digital forms.

Concept of the Information Age

Defined by access to and control of information, marking a significant era in civilization.
Often referred to as the Computer Age, Digital Age, or New Media Age.
Initiated by Claude E. Shannon's work on information theory, introducing binary encoding of information.

Milestones in the Information Age

1970s marked by Internet development and rises of personal computers, initiating the Digital Revolution.
Advancements like fiber optics and faster microprocessors enhanced data transmission and processing.
Emergence of the World Wide Web transformed information exchange and communication methods.

The Digital Age Overview

Represents a shift from an industrialized to a knowledge-based economy, beginning in the 20th century.
Intersects with the Internet Age, signifying changes in information access and global communication.

Digital Age Timeline

1940s: Foundations of information science.
Late 1940s: Initial computer systems automate mathematical operations.
1970s: Launch of first home computers and video game consoles.
1980s: Computers become common in homes and businesses.
Late 1980s - 1990s: Introduction of the World Wide Web publicly and its quick rise in popular culture.
2000s: Surge in cell phone technology and text messaging popularity, fostering global digital engagement.

Emergence of the New Media Age

Transformed communication through faster, electronic means such as email, instant messaging, and social media.
Criticisms arise around the impact on spelling and grammar among users due to the prevalence of "text lingo."

Impacts of New Media

Enhanced accessibility of information for individuals and organizations.
Utilization of platforms like Twitter and Google by news networks for real-time reporting.
The rise of independent news bloggers providing unbiased reporting contrasted with traditional media.

Challenges and Opportunities in New Media

New Problems:
- Issues like multi-identity, cybercrime, privacy concerns, and hate speech.
New Horizons:
- Virtual socialization, cyber entrepreneurship, new business models, and global political movements.

Future Perspective on New Media

Continuous evolution in job creation and content formats driven by advancements in new media technologies.
