Study Notes

Computer Tower Model

Offers more space for additional storage devices compared to desktop models

Desktop Model

Designed to fit on a desk, typically with the monitor on top
Often limited to three internal storage devices
Smaller models are called slimline

Notebook Computer

Lightweight and portable
Typically weighs less than 6 pounds
Uses flat panel technology for display
Comparable in computing power to desktop computers (CPU, memory, drive)
More expensive than a comparable desktop
Uses battery packs

Laptop

Small and portable, designed to fit on your lap
Notebook computers are now the more common term

Workstation

Powerful single-user computer
Has a more powerful processor and higher quality monitor
Used for demanding tasks like engineering work, desktop publishing, and software development
Commonly has a large, high-resolution screen, lots of RAM, built-in network support, and more powerful graphics

Early Computers

1890 Herman Hollerith invents the punch card system to process the 1880 census, saving the government millions and contributing to the foundation of IBM.
1936 Alan Turing proposes the concept of a universal machine, later known as the Turing machine, which forms the basis of modern computers.
1937 J.V. Atanasoff attempts to build the first gearless computer.
1941 Atanasoff and his student build a computer that can solve 29 equations simultaneously, introducing the concept of computer storage.
1943-44 John Mauchly and J. Presper Eckert build ENIAC, considered the first digital computer.
1946 Mauchly and Presper build UNIVAC, the first commercial computer for business and government use.
1947 The transistor is invented, replacing vacuum tubes in computers.
1953 Grace Hopper develops the first computer language, COBOL.
1954 The FORTRAN programming language is created by a team at IBM led by John Backus.
1958 The integrated circuit (computer chip) is unveiled, marking the beginning of miniaturization in computers.

E-Waste

Electronic waste (e-waste) is a broad term encompassing obsolete electronic devices, including “white goods” (refrigerators, washing machines, microwaves) and “brown goods” (TVs, radios, computers).
E-waste is a rapidly growing waste stream, fueled by the growth of electronic products in developed and developing countries.
E-waste contains toxic substances that pose health and environmental risks but also includes valuable recyclable materials.
Although e-waste recycling regulations are strict in developed countries, it’s often more profitable to export e-waste informally to developing countries for processing.
The growing problem of e-waste is related to the increased consumption of electronic devices.
E-waste constitutes more than 5% of all municipal solid waste, globally.
