Session 3: FAQs and Related Articles
FAQs:
1. What is the difference between hardware and software in a computer system? Hardware refers to the physical components, while software refers to the programs and data that run on the hardware.
2. Why is it important for programmers to understand computer systems? Understanding the underlying hardware allows for writing more efficient, optimized, and debuggable code.
3. What is assembly language, and why would a programmer need to know it? Assembly language is a low-level programming language; knowing it helps in understanding how high-level code translates to machine instructions.
4. How does virtual memory work? Virtual memory allows programs to access more memory than is physically available by using disk space as an extension of RAM.
5. What is the role of the operating system in a computer system? The OS manages hardware resources and provides services for applications.
6. What are system calls, and how do they interact with the kernel? System calls are the interface between user programs and the OS kernel.
7. What are some common causes of memory leaks in programs? Memory leaks occur when memory is allocated but not released, leading to eventual system slowdown or crashes.
8. How does caching improve performance? Caches store frequently accessed data closer to the CPU, reducing access times.
9. What is the difference between a process and a thread? A process is an independent program execution, while a thread is a unit of execution within a process.
