Where did I say that.?

It's owned by the BBC not Sky.

Pretty much everyone else who uses them are minions too.

What out of double sided tape.
What idiot would make their own servers.
I wouldn't make my own shoes for teh same reason.

Yep which is why it's good to name something correctly, or descriptive to it's use.

Sweet hasn't the same meaning as eat.
You seem to be getting words and meanings confused again.

No idea they didn;t go into those details.
It;s all here if yuor interested enough to see the details.
I assume you'll be colelcting honey to make your own chips soon.

and the big ones will be more powerful still.
So seems you can't tell the difference between a mainsframe a desktop and a laptop can they can all do the same.
So to store the NHS patient records for the UK can be done on a laptop, and any doctor can access this laptop
because it's a mulit-user device.

> In 1982 when I had a ZX Spectrum, people referred to the "MIP" as a fast supercomputer. A million calculations per second! But now I have between my home computers 30 trillion calculations per second, 30,000,000 times faster, although it does use 13 amps and create enough heat to open the window in winter.

So your computer is just the same as a central heating system because both give out heat.

A hobby, but I'd hardly call it that a passtime perhaps. 9 is hardly a lot, I had 2+ on my in my BBC with 2nd processor and
teletext box in the mid 1980s.
But why differenciate bewteen CPU and GPU it's just a Load of Transistors Doing Stuff maybe call them all LTDS chips.

What makes it a van rather than a car ? What's the differnce and why does it have to be camp.
Is it rainbox colours or is it used for mincing.

You mean like stopping at bus stops, kind of important if you're driving a bus.
