ANSWER : 2 High propagation delay

Explanation : This means that it is not practical for use in systems requiring high-speed operations. The characteristic parameters for the CMOS gate depend on the power supply voltage VDD that is used. The power dissipation increases with increase in voltage supply. The propagation delay decreases with increase in voltage supply and the noise margin is estimated to be about 40% of the voltage supply value.

ANSWER : 1 Operational registers

Explanation : Registers found in processor are called operational registers and in memory unit are called storage registers.

ANSWER : 4 Replacement Operator

Explanation : A replacement operator consisting of the information transfer from one register to another, is designated in symbolic form.

ANSWER : 2 Direct Mapping technique

Explanation : Associative memories are expensive compared to random-access memories because of the added logic associated with each cell. Therefore, the simplest way to determine cache locations in which to store memory blocks is the Direct Mapping.
