COMP 001 Introduction to Computing - Third Generation

The Third Generation

• Integrated circuits marked the third generation of computers, increasing speed and efficiency.
• Transistors were miniaturized and embedded on silicon chips, making computers smaller and more affordable.
• Capable of executing instructions in billionths of a second.
• Users interacted via keyboards and monitors with an operating system managing multiple applications.
• Third generation computers became widely accessible to the public.

The Fourth Generation

• The microprocessor revolutionized the fourth generation by integrating thousands of circuits on a single silicon chip.
• Enabled powerful computers to connect and form networks, leading to the Internet's emergence.
• Introduction of graphical user interfaces (GUIs), the mouse, and handheld devices.
• Artificial Intelligence (AI) research emerged, utilizing parallel processing and superconductors.
• Early inventors recognized the need for computers to solve diverse problems beyond simple calculations, leading to the invention of programming.

Early History of Computing

• The abacus, dating back to at least 1100 BCE, is one of the earliest calculating devices.
• Consists of a rectangular frame with rods and beads, used for arithmetic operations.
• Played a role in developing the Hindu-Arabic numeral system through its ability to represent numbers using a simple set of beads.

Notable Developments in Computing

• Apple's Lisa employed a pioneering microprocessor and introduced a GUI that was more user-friendly.
• The Macintosh, launched in 1984, popularized desktop computers with its ease of use.
• IBM's entry into the personal computer market legitimized the industry and encouraged other companies to participate.
• Hewlett-Packard released the HP-85, a costly machine with a cassette drive and a closed architecture.

Microsoft Windows

• Launched in 1985, Microsoft Windows brought PC capabilities closer to Macintosh features, enhancing the user experience.

Programming Language Characteristics

• Essential features include high efficiency, a structured environment, and clear documentation.
• Must support algorithms, variables, data types, control flow, and debugging.
