Solution
72. When all flip-flop inputs are driven by the same clock signal, the counter is known as a synchronous counter.
therefore the correct option is (a).
74.When the output of one flip-flop is connected to the input of another, this is known as a asynchronous counter.
therefore the correct option is (c).
75. The SIPO describes the shift register used for serial-to-parallel conversion.
therefore the correct option is (a).
76. the four basic parts of ROM architecture are Row decoder, column decoder, register array, and output buffer.
therefore the correct option is (c).
77. The following is not a characteristic of the ideal operational amplifier
very high output impedance. Therefore the correct option is (d).
78. Random Access Memory (RAM) is a type of memory that can be written into only once but can be read from an infinite number of times.
Therefore the correct option is (b).
79.static memory devices are Semiconductor memory devices in which stored data is retained as long as power is applied.
Therefore the correct option is (c).
80. Volatile memory is one in which the Memory loses stored information when electrical power is removed
Therefore the correct option is (b).
