An operation code with n bits will imply that there are _______ possible distinct operations.

Here are the answers to the questions from the GCE paper: 9. An operation code with n bits will imply that there are _______ possible distinct operations. With n bits, each bit can be either 0 or 1. Therefore, the total number of distinct combinations or operations is 2^n. The correct option is B. B 10. The main purpose of a digital certificate is to: A digital certificate serves to verify the identity of the sender or server and to ensure the authenticity and integrity of data, such as a file. The correct option is A. A 11. The binary equivalent of the octal number 625 is: To convert an octal number to binary, convert each octal digit into its 3-bit binary equivalent: 6_8 = 110_2 2_8 = 010_2 5_8 = 101_2 Concatenating these binary representations gives 110010101_2. None of the provided options exactly match 110010101_2. However, if the octal number was 615_8, its binary equivalent would be 110001101_2, which is option C. Given the options
