Part of the history of the computer cannot be told without the emergence of the personal computer. Ed Roberts, the President of a company named MITS Incorporated, oversaw a company that made...

There are basically three ways to make computer chips smaller. One is to make transistors smaller, another is to make chips with fewer transistors and a third possibility is to use software to make...

The early components that would contribute to the development of the computer were invented back in 1939, when Hewlett Packard invented their first product. "Their first product was the HP 200A...

Google provides search results customized for many countries. This modifies the results for any search term by giving preference to sites that cater to that country or which are in the language...

RAM memory stands for "random access memory" and is vital to a computer's performance. Think of it like a computer's "short term memory." The computer stores things there temporarily while it...

The creator of Artificial Intelligence studies begins with the work of pioneer computer scientist Alexander Turing (1912-1954) who in the 1930's evolved a concept of a "Turing Machine." This was...

According to the Merriam-Webster Dictionary, a computer is “a programmable usually electronic device that can store, retrieve, and process data.” The first programmable computer, the Z1, was...

About thirty years ago, the 8086 processor was extremely innovative and important. But this processor is, of course, completely obsolete today. However, it continues to have some impact because...

It really depends on what you are going to call a "computer." The first meaning of the word applied to a person who could do complex calculations quickly, so in that case I think we'd have to get...

/* FunWithArray.c */ #include <stdio.h> #include <stdlib.h> #define MAXSIZEOFARRAY 100int main() { int intArraySize, count; double dblArraySum, dblArrayMean, dblArraySmallest =...

Moore's Law was really not intended as a statement about computer science but simply a rule of thumb about the progress of chip-making during a specific period based on an observation made by...

In Thomas Friedman's breakthrough book The World is Flat, chapter 2 talks about "The Ten Forces that Flattened the World". The breaking of the Berlin Wall World Wide Web/Netscape Productivity...

The miniaturization of high speed computer power is referred to, in the book The World is Flat by Thomas Friedman, as "the steroids". When the Internet made a social impact in 1995 via Netscape and...

What we experience today as the Digital Age came about by the work of many over many years, some of whom are briefly described here. Starting in the mid 1800's, Charles Babbage worked out all the...

I’ve looked over the information thoroughly, and it doesn’t seem as if there is anything to disucss. No discussion question has been asked. Is there something about this that you want us to...

"Hardware" refers to any physical device in computing. If it is something you can touch and see, such as the computer screen, the keyboard, the printer, or the mouse, it is part of the hardware....

I think that one of the most basic ways in which a Google doc can operate in a collaborative setting is that it enables other to make changes to it. When a Google doc is started by one person, it...

Herman Hollerith lived from 1860 to 1929. Of German heritage, he was born in Buffalo, NY, and studied mining engineering – ultimately receiving his PhD from Columbia in 1890. He later went to...

You know, this question is actually a really tricky one to answer for anyone who is not a part of that world. And those who are "part of that world" seem to have trouble explaining it in ways that...

Another kind of danger is one of national security. All sorts of vital functions of the nation are dependent on the internet. In past years, there has been evidence of the Chinese (among others)...

Computers originated not so much with a technology but with an idea. That idea was that it is possible to break down complex activities, whether procedures or mathematical computations, into a...

RAM or random access memory is a form of memory that can be accessed at a very fast rate. It is used by the central processing unit or CPU to write and read data as it performs its operations. The...
