Top 100 Intel Interview Questions and Answers

Contents show

Question 1: What is the purpose of a CPU cache and how does it improve performance?

Answer: A CPU cache stores frequently accessed data and instructions, reducing the need to fetch them from slower main memory. This speeds up processing as the CPU can quickly access data it needs.


Question 2: Explain the difference between RISC and CISC architectures.

Answer: RISC (Reduced Instruction Set Computing) uses a simplified set of instructions, focusing on execution speed. CISC (Complex Instruction Set Computing) includes more complex instructions, potentially executing multiple operations in one.


Question 3: What is the difference between a process and a thread?

Answer: A process is an instance of a program in execution, including its memory space. A thread is a unit of execution within a process, sharing the process’s memory space.


Question 4: How does virtual memory work?

Answer: Virtual memory allows a system to use more RAM than is physically available by utilizing disk space. It does this by moving data between RAM and disk as needed.


Question 5: Explain the purpose of a semaphore in concurrent programming.

Answer: A semaphore is a synchronization primitive used to control access to a shared resource by multiple processes or threads. It helps prevent race conditions.


Question 6: What is the purpose of the volatile keyword in C/C++?

Answer: The volatile keyword tells the compiler not to optimize the variable because it can be changed externally (e.g., by hardware or another thread).


Question 7: Write a code snippet in C to reverse a linked list.

struct Node {
    int data;
    struct Node* next;
};

struct Node* reverseLinkedList(struct Node* head) {
    struct Node* prev = NULL;
    struct Node* current = head;
    struct Node* next = NULL;

    while (current != NULL) {
        next = current->next;
        current->next = prev;
