Which of the following is not a keyword in C ?
Show Hint
Common C keywords to remember: if, else, while, do, for, break, continue, return, int, float, char, struct. If it's used in SQL but not C logic, it's probably not a C keyword!

The Correct Option is C
Solution and Explanation
Keywords are reserved words in C that have a predefined meaning for the compiler and cannot be used as variable names.
1. Standard C Keywords:
There are 32 original keywords in C (ANSI C).
• do, for: Used for loop control.
• break: Used to exit a loop or switch case. 2. The word "join": The word join is often used in SQL or as a function name in multi-threading libraries (like POSIX threads pthread_join), but it is not a reserved keyword in the C programming language itself. 3. Conclusion: Since "join" is not part of the reserved vocabulary of C, it is the correct answer.

- Choose the correct answer from the options given below:
(A). RAID 3 requires only a single redundant disk.
(B) In RAID 4 scheme, two different parity calculations are carried out and stored in separate blocks on different disks.
(C) RAID 5 distributes the parity strips across all disks.
(D) In RAID 2, the number of redundant disks are proportional to the log of the number of data disks. - In case of DMA, after the completion of the transfer, the processor is required to be notified of the completion. This is done through.
