Study Notes
Computer Systems Overview
- Computer systems are composed of hardware and software, facilitating the input, processing, and output of data.
- Input devices allow users to submit data, while output devices display results of the data processing.
Early Computing Devices
- The abacus has been utilized since the Mesopotamian era for basic arithmetic; it’s still used today by some traders and is suitable for visually impaired individuals.
- The astrolabe, also still in use, serves computational needs and does not require a power source.
- Charles Babbage conceptualized the Analytical Engine, featuring components likened to modern computers: store (memory), mill (CPU), reader (input device), and printer (output device).
Significant Historical Computers
- ENIAC (Electronic Numerical Integrator and Calculator), built in 1943, is regarded as the first digital computer and was funded by the U.S. government to compute artillery range tables.
- The creation of ENIAC led to the establishment of the Association for Computing Machinery (ACM).
Key Historical Figures in Computing
- Alan Shugart: Inventor of the floppy disk.
- Alan Turing: Developed the concept of the Turing machine, foundational to modern computing.
Computer Types
- Mainframe: Institutional computers capable of serving numerous users simultaneously, used in applications like blockchain and machine learning.
- Supercomputer: Designed for intensive tasks such as weather forecasting; Fugaku is the most powerful supercomputer as of November 2020, with LINPACK score of 442.01 petaflops, employed in research including simulations related to coronavirus.
Data Representation
- Computers process information using bits (binary digits), signifying two states: 0 (Off/False) and 1 (On/True).
- The power button symbol represents the binary states.
Hardware and Software
- Hardware: Physical components of a computer system, including input devices (e.g., keyboards), output devices (e.g., monitors), and processors (CPUs).
- Software: Intangible components known as programs or applications, instructing hardware on functionality and interaction.
System Unit Clarifications
- Many users incorrectly refer to the computer enclosure as the CPU; it is accurately termed the "system unit."
- The system unit houses the CPU, GPU, storage devices, and internal peripherals, facilitating communication through computer buses, including USB for external devices.
Summary of Terminologies
- Input Device: Accepts data from users.
- Output Device: Displays processing results.
- Processor: Functions as the brain of the computer.
- Flash Drive: USB storage device; commonly misnamed as "USB."
