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."
