Overview
- This chapter covers what computers are, how they work, and how they are used.
- It includes computer terminology, overview of computer history, basic computer types, internet access, and societal impacts.
Computers in Your Life
- Importance of computer literacy
- Pervasive computing (ubiquitous computing)
- Computers are integral parts of daily lives
- Basic computer literacy is essential; understanding computers is important
- Computers were large and expensive before 1980, and accessible to few.
- Microcomputers became inexpensive in the 1980s, significantly increasing computer use.
- Today, nearly all US households have computers and most individuals use them at work.
- Electronic device convergence into single units with multiple capabilities (e.g., e-mail on TV, internet content on mobile devices).
- Computer literacy is vital in modern times
Computers in the Home
- Computers are used for a variety of tasks (information lookup, e-mail, shopping, TV/video watching, music/movie downloads, image organization, gaming, vacation planning).
- Computers are used for reference, productivity, and entertainment. Wireless networking enables computer use in varied locations.
- Smart appliances use built-in computers or communications technology to automate household tasks in smart homes.
Computers in Education
- Today's youth are called the computing generation.
- Most students access computers at school.
- E-books are integrated into some school curricula.
- Colleges and universities are highly integrated with computers.
- Some institutions have computer requirements for enrollment.
- Distance learning is facilitated using computers and internet access via wireless hotspots.
Computers on the Job
- Computers are now essential tools for all types of employees for decision-making, productivity, and communication.
- Used for access control, security measures, service in professional settings, and especially by the military.
- Computer skills must be continuously updated.
- Common uses include decision making, productivity, off-site communication, and authentication.
Computers on the Go
- Encountered in most aspects of daily life.
- This includes consumer kiosks, ATMs, POS systems, self-checkout systems, consumer authentication systems, portable computers, and mobile devices, as well as GPS systems.
Technology and You
- Example of modern technology: Restaurant iPad Ordering Systems.
- Used with e-menus; customers place and pay orders.
- Systems provide additional resources to customers.
What Is a Computer and What Does It Do?
- A computer is a programmable, electronic device.
- It accepts, processes, and stores data according to program instructions.
- Basic operations include input (data entry), processing (operations on data), output (presenting results), storage (saving data/programs), and communications (sending/receiving data).
Data vs. Information
- Data: raw, unorganized facts (text, graphics, audio, video).
- Information: processed data into meaningful form.
- Information processing is the conversion of data into information.
Computers Then and Now
- Computers are a recent invention, part of successive generations with major technological advances.
- Precomputer era (pre-1946) used tools like the abacus, slide rule, mechanical calculator, punch cards, and tabulating machines.
- First-generation (1946-1957): vacuum tubes, enormous, high electricity consumption, significant heat generation (ENIAC and UNIVAC).
- Second-generation (1958-1963): transistors, smaller, more powerful, cheaper, more energy-efficient, more reliable (punch cards and magnetic tape).
- Third-generation (1964-1970): integrated circuits (ICs), even smaller and more reliable.
- Fourth-generation (1971-present): microprocessors, keyboards, mice, monitors, printers, hard drives, flash memory, and development of networks, and the Internet.
- Fifth-generation (present and future): artificial intelligence, voice/touch input, optical computers.
Hardware
- Hardware: Physical components of a computer.
- Internal hardware is located inside the computer's main box (system unit).
- External hardware is located outside the system unit and connects via wired or wireless connections.
- Hardware devices are used for all five basic computer operations.
- Input components (keyboards, mice, scanners, cameras, microphones, touchpads).
- Processing components (CPU, memory).
- Output components (monitors, printers, speakers, projectors).
- Storage components (hard drives, CD/DVDs, flash drives).
- Communications components (modems, network adapters, routers).
Software
- Software: Programs or instructions controlling hardware operations.
- System software: manages computer operations (like operating systems - OS).
- Application software: performs specific tasks.
- Example system software (Operating System - OS) start and control computer operations.
- Examples of operating systems include Windows, MacOS, Linux, Android.
- Example of application software (word processing, multimedia, web browsers, email).
Computer Users and Professionals
- Computer users (end users): obtain information using computers.
- Computer professionals include systems analysts, computer system designers, programmers, operations personnel, and security specialists.
Quick Quiz
- Questions and answers will depend on the specific quiz. This section is for student's preparation.
Additional Notes:
- Figures and diagrams within the presentation are critical for visual understanding of the concepts.
