What is the difference between パソコン vs コンピューター?
Generally, what Faily Feely said in comment is all:
パソコン is thought to be an abbreviation for パーソナルコンピューター (personal computer).
When used as パソコン, I'd imagine a (home) desktop PC.
When used as コンピューター, its meaning is generally the same as English computer, I suppose.
パソコン or "PC" is Japanese abbreviation of personal computer. Your notebook and desktop computer are パソコン.
コンピュータ refers to electronic computor in general which ranges from desktop business-use computors to super highspeed computors that perform quadrillion digit culcuration in a second.
