There are no valves in a modern computer. If by valves you mean vacuum tubes, the equivalent is a transistor. Modern CPUs have many transistors/gates on their dies. The SandyBridge i7, a near-top end general purpose computer COU can have 2.2 billon transistor elements on the CPU die. Of course there are many more transistors incorporated in the logic chips, controllers and video cards in a computer as well.

Yes, much more powerful. So are most ipods.
Computer tubes, also known as vacuum tube computers are programmable computers that uses vacuum tube logic circuitry. They were used to solve computational problems much like modern day computers.
Need FOR DEVELOUPEMENT FOR THE BETTERMENT OF TECHNOLOGY
An example of a modern mini computer is the smartphone. A very popular device used every day by millions of people.

Alan Turing is considered to be the father of the modern computer. He was a mathematician and is the creator of the Turing machine which was the precursor to modern computers.

Konrad Zuse created the modern day computer.
Charles Babbage
Steve Jobs didn't invent the computer. The modern-day computer was invented in 1873 by Charles Babbage.

It depends on how much your computer is damaged that day
Yes! Before the invention and eventual use of valves (ca 1830), keyed trumpets/bugles were used. These worked much like modern day woodwinds, but with many fewer keys. In the 1830's, a competition took place between keyed and valved trumpets. Needles to say, valves won.
