Eventually, the concept of numbers became concrete and familiar enough for counting to arise, at times with sing-song mnemonics to teach sequences to others. All known human languages, except the Piraha language, have words for at least the numerals "one" and "two", and even some animals like the blackbird can distinguish a surprising number of items.
The fact that the K computer is over 60 times faster than the Earth Simulator, and that the Earth Simulator ranks as the 68th system in the world seven years after holding the top spot, demonstrates both the rapid increase in top performance and the widespread growth of supercomputing technology worldwide.
PRIMOS (written in FORTRAN IV, that didn't have pointers, while later versions, around version 18, written in a version of PL/I, called PL/P) Virtual Machine/Basic System Extensions Program Product (BSEPP or VM/SE) Virtual Machine/System Extensions Program Product (SEPP or VM/BSE) Virtual Machine Facility/370 (VM/370), sometimes known as VM/CMS ...
In the first generation, word-oriented computers typically had a single accumulator and an extension, referred to as, e.g., Upper and Lower Accumulator, Accumulator and Multiplier-Quotient (MQ) register. In the second generation, it became common for computers to have multiple addressable accumulators.
Most computers used six-bit character sets because they adequately encoded Hollerith punched cards. It was a major revelation to designers of this period to realize that the data word should be a multiple of the character size. They began to design computers with 12-, 24- and 36-bit data words (e.g., see the TX-2).
I thought it would interesting to pick the 15 computer-related innovations that have most changed my life. 1. Databases -- I once had a job summer filing inventory cards for Diebold. All day long ...
Launch of IBM System/360 – the first series of compatible computers, reversing and stopping the evolution of separate "business" and "scientific" machine architectures; all models used the same basic instruction set architecture and register sizes, in theory allowing programs to be migrated to more or less powerful models as needs changed.
Speaking at the White House this week, President Barack Obama directed Secretary of Labor Tom Perez to overhaul the nation's laws regarding overtime, summing up the workplace concept as, "If you ...
