Explanation:

CISC stands for Complex Instruction Set Computer, which is a type of computer architecture that aims to provide a rich set of powerful instructions that can perform complex operations in a single instruction. The architecture is designed to reduce the number of instructions required to perform a task, thereby increasing the speed and efficiency of the computer.

In CISC architecture, most of the complex instructions are stored in Transistors. Transistors are the basic building blocks of modern electronic devices, including computers. They are used to switch and amplify electrical signals and are essential components of memory, processors, and other electronic circuits.

The complex instructions in CISC architecture are stored in the form of microcode, which is a low-level code that translates high-level instructions into machine code. This microcode is stored in the memory cells of the computer's processor, which are made up of transistors.

Advantages of storing complex instructions in transistors:

1. Faster execution: Storing complex instructions in transistors allows the computer to execute these instructions faster than if they were stored in memory.

2. Reduced memory usage: By storing complex instructions in transistors, the computer can reduce the amount of memory required to store the microcode.

3. More efficient processing: The use of microcode allows the processor to perform complex operations in a single instruction, which reduces the number of instructions required to perform a task and makes processing more efficient.

Conclusion:

In CISC architecture, the use of microcode and the storage of complex instructions in transistors are essential features that enable the computer to execute instructions faster, reduce memory usage, and perform more efficiently.
