SRAM (Static Random Access Memory) uses flip-flop circuits in its memory cells. These flip-flops store each bit of data as a stable state and do not require refreshing, unlike DRAM.

A hash function is commonly used in cryptography and data integrity applications to ensure that a message or piece of data has not been altered. It generates a fixed-size string (hash) from input data. When the data is received, the hash can be recalculated and compared to the original hash to check if the data has been changed or tampered with.

A digital signature is used to identify and verify individuals (ensuring the sender’s identity) and ensure the integrity of the message (making sure the message hasn’t been altered). It is created using the sender's private key and can be verified by anyone using the sender's public key.

Compromising confidential information refers to unauthorized access, disclosure, or leakage of sensitive data. This situation leads to a threat because it can pose a risk to the security, privacy, and integrity of individuals, organizations, or systems.
