The business took off, and its founders made a lot of money and received the credit they deserved for being daring visionaries. But around the same time, Bill Gates and Paul Allen came up with an idea even stranger and more fantastical: This was much weirder than the idea of Jobs and Wozniak.

A computer at least Introduction of the microwave essay some sort of physical reality to it. It came in a box, you could open it up and plug it in and watch lights blink.

An operating system had no tangible incarnation at all. It arrived on a disk, of course, but the disk was, in effect, nothing more than the box that the OS came in. The product itself was a very long string of ones and zeroes that, when properly installed and coddled, gave you the ability to manipulate other very long strings of ones and zeroes.

Even those few who actually understood what a computer operating system was were apt to think of it as a fantastically arcane engineering prodigy, like a breeder reactor or a U-2 spy plane, and not something that could ever be in the parlance of high-tech "productized.

New releases of operating systems are launched as if they were Hollywood blockbusters, with celebrity endorsements, talk show appearances, and world tours.

The market for them is vast enough that people worry about whether it has been monopolized by one company.

Even the least technically-minded people in our society now have at least a hazy idea of what operating systems do; what is more, they have strong opinions about their relative merits.

It is commonly understood, even by technically unsophisticated computer users, that if you have a piece of software that works on your Macintosh, and you move it over onto a Windows machine, it will not run.

Here is my view, which is entirely subjective; but since I have spent a fair amount of time not only using, but programming, Macintoshes, Windows machines, Linux boxes and the BeOS, perhaps it is not so ill-informed as to be completely worthless.

This is a subjective essay, more review than research paper, and so it might seem unfair or biased compared to the technical reviews you can find in PC magazines. Sometimes he would actually manage to get it running and then he would take us for a spin around the block, with a memorable look of wild youthful exhiliration on his face; to his worried passengers, he was a madman, stalling and backfiring around Ames, Iowa and eating the dust of rusty Gremlins and Pintos, but in his own mind he was Dustin Hoffman tooling across the Bay Bridge with the wind in his hair.

One was that romance and image go a long way towards shaping their opinions. If you doubt it and if you have a lot of spare time on your hands just ask anyone who owns a Macintosh and who, on those grounds, imagines him- or herself to be a member of an oppressed minority group.

The other, somewhat subtler point, was that interface is very important. Sure, the MGB was a lousy car in almost every way that counted: But it was fun to drive.

He could listen to the engine and tell what was wrong with it. The steering responded immediately to commands from his hands. But to the driver it was an experience. The analogy between cars and operating systems is not half bad, and so let me run with it for a moment, as a way of giving an executive summary of our situation today.

Imagine a crossroads where four competing auto dealerships are situated. One of them Microsoft is much, much bigger than the others.

It started out years ago selling three-speed bicycles MS-DOS ; these were not perfect, but they worked, and when they broke you could easily fix them. There was a competing bicycle dealership next door Apple that one day began selling motorized vehicles--expensive but attractively styled cars with their innards hermetically sealed, so that how they worked was something of a mystery.

The big dealership responded by rushing a moped upgrade kit the original Windows onto the market.Technical Notes: Superconductivity also seems to be an example of a process that runs forever. Most physics textbooks explain that superconductivity is not perpetual motion because it is .

Coaxial cable is widely used for cable television systems, office buildings, and other worksites for local area networks. The cables consist of copper or aluminum wire wrapped with insulating layer typically of a flexible material with a high dielectric constant, all of which are surrounded by a conductive layer.
