IF YOU WRITE SOMETHING ON YOUR LAPTOP AND COMMIT IT TO A DISC INSTEADOF PRINTING IT OUT ONTO PAPER IS IT STILLYOUR INTELLECTUAL PROPERTY IF SOMEONE USES IT OR IS THAT ONLY FOR PRINTED MATTER?
Yes, it is still your intellectual property and automatically covered for copyright from the minute you finish it until 70 years after your death.
There is no need to register copyright in the UK, it is automatic.
However in some cases you may have to prove when a work was made (a common way for songwriters in the past was to post themselves a copy of the piece and keep the letter unopened).
If you have published a book then you should donate the required copies to the various UK copyright libraries (this can work out expensive and many people do not bother).

Here in the US, and before the advent of personal computers, we did exactly this - send ourselves a copy of the work and keep it unopened. It was important that the date-stamp from the post office be on the envelope opening, so that it couldn't be tampered with.
In the US it's now generally accepted (according to my understanding) that any work is considered copyright when it is posted/sent to any other person or published in paper format or on the web.
But, if you sell it, there are many different ways of doing this. For instance there are First North American Serial Rights, where the copyright returns to the author after first printing. Then there are are worldwide rights and then "all rights" which is exactly what it sounds like. Then there are companies who buy movie rights and those that don't.
Also in dealing with websites, some retain the right to use your work to advertise their site in perpetuity, and some recognize that the author is the sole right holder of the work. Read your TOS before you publish anything on a public site if you care about its copyright!
Of course the US Copyright Office suggests you copyright your every piece of work thru them. Which runs, I think, $35 per document. (An insane price if you are even mildly prolific!)
Yep copyright law gets pretty complex. And if you're paid for your work, read the contract with care.
