Computers in Your Life:
- Why learn about computers? (Pervasive/ubiquitous computing, computers are a part of daily life, basic computer literacy)
- Before 1980: computers were large and expensive, used for high-volume processing
- Microcomputers in early 1980s: inexpensive personal computers, increased computer use
- Today: nearly 90% of households use computers, electronic devices converge, computer literacy is essential
- Illustrative examples (figure 1-1 - convergence of devices)
-
Computers in the Home:
- Variety of tasks (lookup info, email, shopping, watching TV, downloading music/movies, organizing photos, playing games, vacation plans).
- Wireless networking
- Smart appliances (built in computer/communication technology).
- Smart homes (tasks monitored/controlled by main computer)
-

- Wireless hotspots
- Distance learning
- Illustrative examples (figure 1-3 - illustrations of computer use)
-
Computers on the Job:
- Computers are universal tools for decision-making, productivity, and communication
- Use cases: employee types, access control, service professional use, military, common uses (decision making, productivity, off-site communication, authentication)
- (Illustrative examples figure 1-4 - illustrations of computer use in the job setting)
-
Computers on the Go:
- Computers are encountered in many aspects of daily life

- Information: data that's been processed into a meaningful form
- Information processing: converting data to information
-
Computer's History:
- Evolution across several centuries
- Categorization into generations based on technology:
- First generation (1946-1957) - vacuum tubes, ENIAC, and UNIVAC
- Second generation (1958-1963) - transistors, cheaper/more efficient/reliable
- Third generation (1964-1970) - integrated circuits (ICs), smaller computers
- Fourth generation (1971-present) - very large scale integration (VLSI), microprocessors, IBM PCs, Apple Macintosh
- Fifth generation (present and future) - artificial intelligence, ultra large-scale integration (ULSI), parallel processing
