An operating system is software (or, sometimes, firmware) that manages and controls a computer, serving as an interface between various applications and the computer hardware. End users do not...

In computer science, round robin is the name for a type of algorithm. The name might make one think of round-robin storytelling, which is a kind of storytelling where everyone present has an equal...

Before answering this question, it will be useful to briefly define computer hardware and computer software. Hardware refers to any of the physical elements of a computer. This includes the central...

When most end-users encounter computers, they are working on what are sometimes referred to as "virtual machines." In other words, when you interact with a computer or smart phone, there are many...

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...

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...

A basic conditional expression is one in which a particular input variable is tested; the result of the same determines what the value of an output variable is. For example, consider the expression...

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...

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...

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...

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)...

If you look at the recent history of computers and microchips, the technology has gotten much smaller, faster, and less expensive. Moore's Law basically states that the number of transistors that...

The major difference between these two kinds of programming is where the program runs. Client-side programming runs on the client's computers while server-side programming runs on the company's...

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...

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 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...

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...

Computers use inputs and outputs to do various tasks. Computers receive programs in various codes and use them to do complex tasks. The first computers were the size of a room and relied on a...

"Virtual reality" is a "reality" that is created within the constructs of a computer. It has no basis in actual physical constructs. Virtual reality (VR) is a computer-generated three-dimensional...

I agree with readerofbooks, it would be helpful to know what kind of website you want. I would suggest that you try weebly (see the link below). You can sign up for free and you can actually...

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...

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...

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

Many tasks in computer programs need to be repeated. Normally, the code used for this is iterative, instructing the computer to perform a series of operations multiple times until certain...

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...

The Raspberry operating system (OS) is based on the Linux distributions, so the commands for the former will pertain to the commands for the latter. One command that often comes in handy is ls....

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...

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...
