It depends on the specific use case and requirements.

• TCP is reliable and ensures all data is delivered in order, but it can be slower due to the overhead of error-checking and retransmission.

• UDP is faster and more efficient for real-time applications like video streaming or online gaming, but it does not guarantee delivery or order of packets.

• Choose TCP for applications that require reliable data transmission, such as ...read more

Hashing is a process of converting input data into a fixed-size string of bytes using a mathematical algorithm.

• Hashing is commonly used in password storage to securely store user passwords without storing the actual password.

• Hashing is used in digital signatures to ensure the integrity of the signed data.

• Blockchain technology uses hashing to create a secure and tamper-proof record of transactions.

• File integrity checks ...read more
