Features of External Hardware Computer Components
External computer components connect to a computer system from OUTSIDE. They are not necessary for the system to function but make our experiences easier or better. We will discuss the following:
* Input Devices (used to get data into a computer)
*Output Devices (used to get information out of a computer)
*...

Useful programs
Here are some computer programs useful in understanding and implementing dissonance-based tuning and timbres. Since I usually program in the language MATLAB, most of these are MATLAB programs, although the dissonance calculating program is also available...
Different between hardware and software?
The beauty of a computer is that it can run a word-processing program one minute and then a photo-editing program five seconds later. In other words, although we don't really think of it this way, the computer can be reprogrammed as many times as you like. This is why programs are also called software....
What do you mean by operating system?
Suppose you're back in the late 1970, before off-the-shelf computer programs have really been invented. You want to program your computer to work as a word processor so you can bash out your first novel—which is relatively...
what is computer program?
As you can read in our long article on computer history, the first computers were gigantic calculating machines and all they ever really did was "crunch numbers": solve lengthy, difficult, or tedious mathematical problems. Today, computers work on a much wider variety of problems but they are all still,...
The Importance of the main() Function in C Programming
By Dan Gookin from C All-in-One Desk Reference For Dummies
All C language programs must have a main() function. It's the core of every program. It's required. The main() function doesn't really have to do anything other than be present inside your C source code. Eventually, it contains instructions...
Programming the ENIAC
Built in 1943-45 at the Moore School of the University of Pennsylvania for the War effort by John Mauchly and J. Presper Eckert (no relation to Columbia University's Wallace Eckert) but not delivered to the Army until just after the end of the war, the Electronic Numerical Integrator And Computer (ENIAC)...
Multi function device (MFD)
A product or device that has multiple functions. An example of this might be a printer that also makes copies, faxes, and scans. Another example is a CD or DVD that might contain multiple applications on the same disk; this may be a Mac and PC version of the same software or media meant to be played...
