Performance metrics Quantifying the efficiency and speed of a computer system including factors like clock speed MIPS and throughput Questions and Answers 1 What are the main components of a computer system Answer The main components of a computer system are the CPU memory IO devices and the interconnection network connecting them These components work together to process data and execute instructions 2 How does a CPU execute instructions Answer The CPU fetches instructions from memory decodes them and executes them according to the defined ISA This involves fetching operands from memory performing operations and storing the result back to memory 3 Explain the concept of cache memory and its advantages Answer Cache memory is a smaller faster memory that stores frequently accessed data reducing the need for frequent access to main memory This significantly improves performance by minimizing latency and increasing the rate of data access 4 What is the purpose of an instruction set architecture ISA 3 Answer An ISA defines the set of instructions that a CPU can understand and execute It acts as a language between the CPU and the software Different CPU architectures have different ISAs determining the capabilities and performance of the processor 5 How does pipelining work and what are its benefits Answer Pipelining speeds up instruction execution by overlapping different stages of the instruction processing cycle For example while one instruction is being decoded another can be fetched allowing multiple instructions to be processed simultaneously This technique significantly improves the throughput of the CPU FAQs 1 What is the difference between a CPU and a GPU Answer CPUs are designed for generalpurpose computing handling a wide range of tasks efficiently GPUs on the other hand are specialized processors designed for parallel processing primarily used in graphics rendering and scientific computing applications 2 How does memory hierarchy work in a computer system Answer A memory hierarchy consists of multiple levels of memory with varying speeds and capacities The fastest and smallest cache is closest to the CPU followed by the main memory and finally the slower and larger secondary storage This layered approach optimizes performance by prioritizing frequently accessed data while providing sufficient storage space 3 What are some of the challenges facing computer architecture in the future Answer As technology advances computer architects face challenges like designing for energy efficiency managing
