No BM in Science and Math

Why the Malaysian Government insists of using English for Science and Math. This is because the whole world uses the language as an information and/or technology language. How dangerous it will be if we try to use BM, especially in school.
Example:-
Hardware= barangkeras
Software = baranglumbut
Joystick =batang gembira
Plug and Play= cucuk dan main
Port = lubang
Server = pelayan
Client = pelanggan

Try to translate this :
That server gives a plug and play service to the client using either hardware or software joystick. the joystick goes into the port of the client.

Now u know why?
