1. TRUE OR FALSE.a) Unicode is a 8-bit code, occupying twice the disk space for text as EBCDICwould require.b) Hamming codes, used for error detection and correction, are useful for bursterrors (where we could reasonably expect multiple adjacent bits to be incorrect).c) CRCs are useful for error correction.d) A byte is 8 bits, but a word may vary in size (16-bits, 32-bits, etc.) from onearchitecture to another.e) The largest value that a 60-bit signed binary integer can represent is (260 -1).f) An Excess-M integer representation includes more negative numbers than itdoes positive ones.
