Study Notes
Overview of Computers
- Computers are programmable devices that process, store, and retrieve data based on software instructions.
- They play a vital role in society, significantly transforming global communication and operations.
Historical Context
- The term “computer” initially referred to a person who performed calculations manually.
- Early digital computers of the 1940s and 1950s were large machines filled with vacuum tubes, significantly less powerful than modern personal computers.
Key Figures in Analog Computing
- James Thomson was instrumental in analog computation during the 19th century, creating devices such as integrators.
- Vannevar Bush developed the Differential Analyzer, the first large-scale general-purpose analog computer that effectively resolved differential equations.
Generational Advancements
- The first generation of digital computers utilized vacuum tubes; significant examples include:
- Atanasoff-Berry Computer (ABC, 1942)
- Colossus (1944)
- ENIAC (mid-1940s)
- UNIVAC I (1951)
- The second generation introduced transistors, which replaced vacuum tubes for improved efficiency and size.
- The third generation utilized semiconductors, leading to faster and more reliable computers.
- The fourth generation saw the emergence of microprocessors, with the Intel P4004 (1969) being the first, integrating numerous functions into a single chip.
Components of Computers
- All computers consist of hardware (physical components) and software (instruction sets).
Central Processing Unit (CPU)
- Manages functions through three main components:
- Memory Unit: Stores and transmits data for processing.
- Control Unit: Interprets commands and oversees data flow.
- Arithmetic-Logic Unit (ALU): Performs all mathematical operations and comparisons.
Input and Output Units
- Input Units: Convert user commands into a digital format; examples include keyboards and mice.
- Output Units: Display results after processing; common examples are monitors and printers.
Operating System (OS)
- An OS is software that controls hardware and provides functionality to users.
- Major functions include managing hardware, enabling multitasking, and ensuring system performance.
Popular Operating Systems
- Microsoft Windows: Dominates with over 90% market share in PCs, offers a graphical interface and wide application compatibility.
- Mac OS: Developed by Apple for Macintosh, known for its user-friendly GUI and security features.
- Android: A mobile OS designed by Google, prevalent in smartphones and tablets.
Advantages and Disadvantages of Operating Systems
-
