1)Define CPU with two major sections of it.
2)Explain how a cache memory helps in improving the overall processing speed of a computer system.
Answers
Explanation:
Ans1) Central processing units have two primary components: the control unit that regulates the processor's operation and the arithmetic logic unit that actually crunches numbers and compares values. However, these two clusters of transistors still rely on memory resources in the computer the CPU powers in order to function.
Ans2) Cache memory holds frequently used instructions/data which the processor may require next and it is faster access memory than RAM, since it is on the same chip as the processor. This reduces the need for frequent slower memory retrievals from main memory, which may otherwise keep the CPU waiting.
Answer:
1.A central processing unit, also called a central processor, main processor or just processor, is the electronic circuitry that executes instructions comprising a computer program. The CPU performs basic arithmetic, logic, controlling, and input/output operations specified by the instructions in the program.

The two main components of the CPU is Control unit and ALU.
The two typical components of a CPU include the following: The arithmetic logic unit (ALU), which performs arithmetic and logical operations. ...
An arithmetic logic unit (ALU) is a digital circuit used to perform arithmetic and logic operations.
2.Cache memory holds frequently used instructions/data which the processor may require next and it is faster access memory than RAM, since it is on the same chip as the processor. This reduces the need for frequent slower memory retrievals from main memory, which may otherwise keep the CPU waiting.
