UDP is preferred over TCP in this project due to its low latency and lightweight nature.

• UDP is a connectionless protocol, which means it does not establish a direct connection between the sender and receiver.

• UDP is faster than TCP as it does not have the overhead of establishing and maintaining a connection.

• UDP is suitable for applications where real-time data transmission is crucial, such as video streaming or online ...read more

To clear the 7th bit in a 32-bit register, perform a bitwise AND operation with a mask that has all bits set to 1 except the 7th bit.

• Create a mask with the 7th bit set to 0 and all other bits set to 1

• Perform a bitwise AND operation between the register and the mask

• Store the result back in the register

The question asks to fill the blanks in a pyramid where each number is the sum of the numbers in the bottom two cells.

An SR flip-flop can be implemented using NAND gates.

• Use two NAND gates to create the SR flip-flop.

• Connect the output of one NAND gate to the input of the other NAND gate.

• Connect the Set (S) and Reset (R) inputs to the inputs of the NAND gates.

• The output of the first NAND gate is the Q output, and the output of the second NAND gate is the Q̅ output.
