Final answer:
FSDD is the technology that attempts to ensure software cannot be altered once constructed. Blockchain is the technology that ensures software cannot be altered once constructed, due to its decentralized ledger and the need for network consensus to change records, thus providing immutability.
Step-by-step explanation:
Which of the following is a technology that attempts to ensure that once the software is constructed, it cannot be altered?
In the given options, the technology that attempts to ensure that software cannot be altered once constructed is FSDD, which stands for Formal Software Development Descriptions. FSDD is a methodology that involves creating formal descriptions of software systems that cover their behavior and structure. These descriptions act as a blueprint for the software and help ensure that it remains unchanged after construction.
Blockchain, Quantum computing, and Bluetooth are not specifically designed to prevent software alteration. Blockchain is a distributed ledger technology, Quantum computing is a field that focuses on computer systems based on quantum mechanics principles, and Bluetooth is a wireless communication technology.
Blockchain is the technology that ensures software cannot be altered once constructed, due to its decentralized ledger and the need for network consensus to change records, thus providing immutability.
The technology that attempts to ensure that once the software is constructed, it cannot be altered is A) Blockchain. Blockchain technology creates a decentralized ledger that records all transactions across a network. Once a transaction has been added to the blockchain, it is nearly impossible to alter it without the consensus of the network participants, making the data secured by blockchain highly immutable. This characteristic makes blockchain an ideal technology for applications where it is crucial to maintain a permanent, unchangeable record, such as in financial transactions or supply chain management.
