TPM
Trusted Platform Module
A hardware chip that securely stores keys and supports measured boot.
A TPM is a dedicated hardware chip that stores cryptographic keys, performs measured boot, and supports attestation that a system started in a known good state. It anchors trust for full disk encryption such as BitLocker by sealing keys to platform integrity measurements. Compared with an HSM, which is a higher capacity device for server side key operations, a TPM is bound to a single host. Storing keys in hardware resists extraction by software based attacks.
Trusted Platform Module: a chip soldered to one device, holding that single device keys (e.g., full-disk encryption).
Looking TPM up is step one. Getting tested on it is step two.
