Cache memory in a computer system ___________.
A. Increases the cost of the computer system
B. Increases the main memory
C. Improves the speed of program execution
D. Increases the speed of Input/output
Mark the correct option:

Correct option is C

The correct answer is (c) Only statement A and C are correct. Cache memory increases the cost of the computer and improves the speed of program execution by providing fast access to frequently used data.
Important Key Points:
1. Cache Memory: It is a high-speed memory located between the CPU and RAM that stores frequently used data for faster access.
2. Cost vs Performance: Cache memory improves system performance but also increases the cost due to its high speed and low storage capacity compared to main memory.
Knowledge Booster:
· Levels of Cache:
· L1: Located directly within the CPU, providing the fastest access.
· L2 and L3: Located near the CPU and provide larger capacity but slightly slower access.
· Role in Execution: By reducing the time taken to access data from main memory, cache improves the overall speed of program execution.
