Q.1) Mark the following statements as true or false and correct the second part if false: 1. The number (1.638125x235) expressed in IEEE 32-bit floating-point format as: 10010011 10100010000000000000000 2. The header of the CD-ROM format contains the block address and the mode byte, in which:-Mode 0 and Mode 1 : Blank data Field, Mode 2: use of an ECC. 3.
