Twisted pair: A type of cabling used for data and voice communications, characterized by pairs of wires twisted together. The twisting helps to reduce interference and noise. This cable type can be found in various versions, including unshielded twisted pair (UTP) and shielded twisted pair (STP), each offering different levels of protection against electromagnetic interference.

Two-Factor Authentication: A security measure that requires a user to provide two different types of credentials to verify their identity before they can access a system or data. This typically involves a combination of something the user knows (like a password), something the user has (like a physical token or a smartphone app), or something the user is (like a biometric characteristic).

Twofish: A symmetric key block cipher known for its simplicity and speed. It was one of the five finalists in the Advanced Encryption Standard (AES) contest, where it was praised for its high security, good performance, and ease of implementation.

Two-person control: A security concept used to maintain high levels of safety and integrity by ensuring that two or more individuals are required to perform certain sensitive or high-risk tasks. This technique prevents a single individual from having sole authority or access and is often applied to prevent fraudulent activities or unauthorized actions.

Two-phase commit: A protocol used in distributed computing to achieve consensus across multiple systems or components during a transaction. The protocol involves two phases - the prepare phase, where all systems are asked if they are ready to commit to a transaction, and the commit phase, where the transaction is either committed on all systems or rolled back on all systems to maintain consistency.

Type 1 authentication factor: A type of authentication factor that is based on something a user knows, such as a password or PIN. It is used in information security to verify the identity of a user. Examples include a password and a security question. This is also known as knowledge-based authentication.
