Help I don't know what is wrong?

What is true about any clock signal in a computing system? Clock period is constant. Duty ratio is always 50% It provides train of alternating logical 0 and 1 signal to rest of the system. Duty ratio can vary over operation period. A number system has symbol set as a, b, c, d, e, f. What is the base of this number system? Convert decimal value 200 into 8-bit 2's complement binary representation. 10001100 None of these 11001000 Not possible to convert Incorrect !!! Think first about range of the given binary format specification. If MIPS instruction format would have allocated 5-bits for OpCode field and 5-bits for function code field, what would be maximum number of instructions be there for MIPS processor? Incorrect !!! Think how many R-type and non-R type instructions would be possible to be encoded
