Children and youth use times the recommended amount of technology, with serious and often life threatening consequences Kaiser FoundationActive Healthy Kids Canada Handheld devices cell phones, tablets, electronic games have dramatically increased the accessibility and usage of technology, especially by very young children Common Sense Media, Following are 10 research-based reasons for this ban.
Computers Timeline The 20th century was nearly into its fourth decade before the first electronic computer came along, and those early machines were behemoths capable of only the most basic tasks. Today, tiny "handhelds" are used for word processing and storage, delivery of documents and images, inventory management, and remote access by workers to central offices.
Programmable electronic devices of all sorts have come to pervade modern society to such a degree that future generations may well designate the 20th century as the Computer Age. This paper, as well as later research by Shannon, lays the groundwork for the future telecommunications and computer industries.
The obscure project, called the Atanasoff-Berry Computer ABCincorporates binary arithmetic and electronic switching.
Before the computer is perfected, Atanasoff is recruited by the Naval Ordnance Laboratory and never resumes its research and development. First binary digital computers are developed The first binary digital computers are developed. In Germany, Konrad Zuse develops the first programmable calculator, the Z2, using binary numbers and Boolean algebra—programmed with punched tape.
On average, Colossus deciphers a coded message in two hours. Specifications of a stored-program computer Two mathematicians, Briton Alan Turing and Hungarian John von Neumann, work independently on the specifications of a stored-program computer.
Von Neumann writes a document describing a computer on which data and programs can be stored. Turing publishes a paper on an Automatic Computing Engine, based on the principles of speed and memory. The Electronic Numerical Integrator and Computer ENIACused for ballistics computations, weighs 30 tons and includes 18, vacuum tubes, 6, switches, and 1, relays.
Transistor is invented John Bardeen, Walter H. Brattain, and William B. Shockley of Bell Telephone Laboratories invent the transistor. First computer designed for U. Attaining the rank of rear admiral in a navy career that brackets her work at Harvard and Eckert-Mauchly, Hopper eventually becomes the driving force behind many advanced automated programming technologies.
First disk drive for random-access storage of data IBM engineers led by Reynold Johnson design the first disk drive for random-access storage of data, offering more surface area for magnetization and storage than earlier drums. In later drives a protective "boundary layer" of air between the heads and the disk surface would be provided by the spinning disk itself.
The Model Disk Storage unit, later called the Random Access Method of Accounting and Control, is released in with a stack of fifty inch aluminum disks storing 5 million bytes of data. FORTRAN is a way to express scientific and mathematical computations with a programming language similar to mathematical formulas.
Both dominate the computer-language world for the next 2 decades. Operated by one person, it features a cathode-ray tube display and a light pen.
Other schools and universities adopt it, and computer manufacturers begin to provide BASIC translators with their systems. Computer mouse makes its public debut The computer mouse makes its public debut during a demonstration at a computer conference in San Francisco.
Its inventor, Douglas Engelbart of the Stanford Research Institute, also demonstrates other user-friendly technologies such as hypermedia with object linking and addressing. Engelbart receives a patent for the mouse 2 years later.
First home computer is marketed to hobbyists The Altairwidely considered the first home computer, is marketed to hobbyists by Micro Instrumentation Telemetry Systems. They start the project by forming a partnership called Microsoft.
Apple II is released Apple Computer, founded by electronics hobbyists Steve Jobs and Steve Wozniak, releases the Apple II, a desktop personal computer for the mass market that features a keyboard, video monitor, mouse, and random-access memory RAM that can be expanded by the user.
Independent software manufacturers begin to create applications for it. The GRiD Compass has kilobytes of bubble memory and a folding electroluminescent display screen in a magnesium case. First commercially successful business application Harvard MBA student Daniel Bricklin and programmer Bob Frankston launch the VisiCalc spreadsheet for the Apple II, a program that helps drive sales of the personal computer and becomes its first commercially successful business application.You know that feeling when you’re midway through doing something — maybe listening to a nostalgic song, maybe dancing — and some fundamentally huge penny drops in your head?
