Mutex is used for exclusive access to a resource by a single thread, while semaphore is used for controlling access to a resource by multiple threads.

• Mutex is binary in nature, allowing only one thread to access the resource at a time.

• Semaphore can have a count greater than 1, allowing multiple threads to access the resource simultaneously.

• Mutex is typically used for protecting critical sections of code.

• Semaphore is of...read more

When volatile and const are used together, the variable is treated as read-only and its value can change unexpectedly.

• The const keyword indicates that the variable's value cannot be changed by the program.

• The volatile keyword tells the compiler that the variable's value may change at any time, even if it doesn't appear to be modified by the program.

• When used together, the variable is treated as read-only by the program...read more

Brute force can be both good and bad depending on the context and application.

• Brute force can be effective for small scale problems or when time is limited.

• However, it is inefficient and impractical for large scale problems.

• Brute force may also be necessary in certain scenarios where no other efficient solution exists.

• For example, brute force can be used in password cracking when other methods fail.

When volatile and const are used together, the variable is treated as read-only and its value can change unexpectedly.

• Using volatile and const together is rare but can be useful for memory-mapped hardware registers.

• The volatile keyword tells the compiler that the variable can be changed unexpectedly, while const ensures the variable is read-only.

• Example: const volatile int * const ptr = (int *)0x1234; // pointer to a r...read more

DDOS attack is a malicious attempt to disrupt normal traffic of a targeted server or network by overwhelming it with a flood of internet traffic.

• DDOS stands for Distributed Denial of Service attack.

• Attackers use multiple compromised systems to flood the target with traffic.

• Common types include UDP flood, SYN flood, and HTTP flood.

• DDOS attacks can lead to service disruption, financial losses, and reputational damage.

Google search works by crawling and indexing web pages, and then ranking them based on relevance and quality.

• Google uses web crawlers to discover and index web pages.

• The search algorithm ranks pages based on relevance to the search query.

• Factors like keywords, backlinks, and user experience influence rankings.

• Google constantly updates its algorithm to improve search results.

• Google also considers user location and searc

I prioritize tasks, set boundaries, delegate when necessary, and make time for self-care.

• Prioritize tasks based on deadlines and importance

• Set boundaries by establishing work hours and sticking to them

• Delegate tasks to team members when feeling overwhelmed

• Make time for self-care activities such as exercise, hobbies, and relaxation

• Avoid multitasking and focus on one task at a time

Yes, ISO 9000 is a set of international standards for quality management and quality assurance.

• ISO 9000 is a series of standards developed by the International Organization for Standardization (ISO) that focus on quality management systems.

• These standards provide guidance and tools for companies to ensure their products and services consistently meet customer requirements and regulatory standards.

• ISO 9000 certification...read more
