The ACID property that ensures transactions are isolated from each other to prevent interference is Isolation. Isolation ensures that concurrent transactions do not see each other's intermediate states, thus preventing interference and maintaining data integrity.

The correct option is "Replication." Durability in ACID properties refers to the guarantee that once a transaction is committed, its changes will persist even in the event of system failures or crashes. Replication techniques, such as maintaining multiple copies of data across different storage locations or using backup servers, are employed to ensure data durability. These strategies help in recovering data and maintaining system availability despite hardware or software failures.

Representational State Transfer (REST) is an architectural style for distributed hypermedia systems. It emphasizes scalability, reliability, and the uniform interface between components. RESTful APIs use HTTP methods like GET, POST, PUT, DELETE to manipulate resources.

To calculate the total balance for each customer across multiple accounts in a banking application using SQL, you would typically use a JOIN statement with GROUP BY and SUM functions. This approach involves joining the tables that contain customer information and account balances, grouping the results by customer ID, and then summing up the balances to get the total balance for each customer. For example, if you have separate tables for customers and accounts, you would join these tables on the customer ID, group by customer ID, and use the SUM function to calculate the total balance. This method provides an efficient way to aggregate data across multiple accounts for each customer.

Git hooks are scripts that can be triggered by various Git events such as pre-commit, post-commit, pre-push, etc. These scripts allow developers to automate tasks or enforce certain rules and policies in the development workflow. For example, a pre-commit hook can be used to run code linting checks before allowing a commit, ensuring code quality standards are met. Similarly, a pre-push hook can be used to trigger unit tests before pushing changes to a remote repository, ensuring that only passing code is pushed. Git hooks provide a powerful way to customize and streamline the development process.

Singly linked lists only allow traversal in one direction, from head to tail, while doubly linked lists allow traversal in both directions, which enhances flexibility but comes with higher memory overhead.

The correct option is Content-Type. The Content-Type header in HTTP requests and responses specifies the media type of the data being sent or received. For example, it can indicate whether the data is in JSON, XML, HTML, or another format. This header helps the client and server understand how to handle the data appropriately.

In a legacy system, normalization involves identifying redundant data and dividing tables to eliminate anomalies such as update, insertion, and deletion anomalies. This is achieved by breaking down data into fewer tables, using foreign keys to establish relationships, and ensuring data integrity. Combining tables or using non-normalized data would not address the underlying issues of redundancy and anomalies.

The File Allocation Table (FAT) is a crucial component in a file system that maintains a record of which disk blocks are free and which are allocated to files. It's commonly used in older file systems like FAT32.

SSID stands for Service Set Identifier. It is a unique name that identifies a specific wireless network. Devices use SSIDs to connect to the correct network among the multiple networks available in the vicinity.
