What Is the Difference between ‘Intrinsic Gas’ and ‘Execution Gas’?

Intrinsic gas is the fixed cost required to include a transaction in a block, covering basic costs like signature verification and data transfer. Execution gas is the variable cost incurred for running the actual smart contract code, including computational steps and storage operations within the Ethereum Virtual Machine (EVM).
