Was the first computer invented before the first television computer invented before the first television?
The first commercially available TV was sold by RCA in 1939. It received up to 5 channels (VHF 1, 2, 3, 4, 5 -- we no longer have channel 1 but 2 to 5 are the same). Sales were stopped in 1941 due to the start of WW2. Analog computers of both mechanical and electronic types were available before this. Digital computers of both electromechanical and electronic types were not available until after this. Both were roughly 3 orders of magnitude more expensive than the top of the line RCA TV of 1939 through 1941. The very first invention of a TV was just before WW1 but they were mechanical and not practical to build and sell. The very first known invention of an analog computer was around 100 BC, but it was mechanical. The very first invention of a digital computer was in the 1830s by Babbage, but it was mechanical and he was never able to build it.
Who first discovered that computers need a CPU?
The computer was invented, not discovered. Discovery implies that it already existed before we became aware of it. There is no single inventor of the computer, various people invented various calculating machines at various times until the equivalent of a "critical mass" was achieved and all the right pieces started coming together. Also the answer to your question depends on your definition of "computer".
