if not copy... how to say terms like COMPUTER, ELECTRONIC in BM?

Microsoft, sugguh-kecil-lembut???

well, in chinese usually (even brand name) they will maximized the used of the meaning of the word instead of direct translate it's pronounciations

in chinese, Microsoft is 微软 (wei ruan), 微= Micro 软=Soft

Television =电视机; 电=electric 视=vision 机=machine
Telephone = 电话; 电=electric 话= conversation
Computer = 电脑; 电=electric 脑=brain

etc etc....

Japanese they have 26 characters of Kanji that's borrow from Chinese languages

those you stated are Katagana, Television (become Te re bi), & 7-11 etc... are direct translate from the pronouciation, which doesnt reflect the meaning in Japanese. those that reflect meanings in the language will be written in Hiragana.

but what i;ve shown you is, instead of using chinese character to spell Te-Le-Vi-Si-En in chinese, they used chinese words to make up Electrical-Vision-Machine.
