Off-site storage is a key component of disaster recovery strategies because it protects critical data from local disasters and facility failures. In Information Technology, disaster recovery focuses on restoring systems, applications, and data after disruptive events such as fires, floods, theft, ransomware, or power failures. If backups are stored only on-site, the same event that damages the primary systems can destroy the backups as well. Off-site storage places backup copies in a physically separate location, reducing the risk of total data loss. It may be implemented through secure tape vaulting, remote backup servers, third-party backup facilities, or cloud-based backup services. Disaster recovery planning typically defines backup schedules, retention periods, recovery procedures, and target recovery goals, such as recovery time objective and recovery point objective. While user authentication supports security and parallel processing relates to performance, they are not core elements that ensure data remains available after a site-level disaster.
Therefore, off-site storage is correctly identified as a component of disaster recovery strategies.

An input device is any hardware device that sends data to a computer, allowing you to interact with and control it. Input devices enable users to input information into the computer system. Let's break down the options:
*Flash Drive (A): A flash drive (also known as a USB drive or thumb drive) is a storage device, not an input device. It allows you to store and transfer data but does not directly input data into the computer.
*CD (B): A CD (compact disc) is also a storage medium, typically used for storing audio, video, or software files. Like a flash drive, it is not an input device.
*Scanner : A scanner is a classic example of an input device. It captures physical documents, images, or text and converts them into digital data that the computer can process. Scanners are commonly used for tasks like digitizing photos, creating PDFs, or scanning documents.
*Printer (D): A printer is an output device, not an input device. It produces hard copies (printed documents) based on digital data received from the computer.
In summary, the correct answer is C. Scanner, as it directly inputs data into the computer system.

A distributed database is a database in which data is stored across multiple computers or servers rather than in a single central location. These machines may be in the same building, across a campus, or in different geographic regions. In Information Technology and database design, distributed databases are used to improve availability, fault tolerance, scalability, and performance by placing data closer to users and by reducing reliance on one server. The distributed database management system coordinates storage, replication, and query processing so that users can access data as if it were a single database, even though it is physically spread out. This model supports business continuity because if one site fails, another site can continue serving requests depending on the replication strategy. Relational and NoSQL describe data models and query approaches, while cloud describes a deployment environment that can host many types of databases, including distributed ones. Because the defining requirement here is data stored on different machines and locations, the correct answer is a distributed database.

In the DIKW hierarchy, the value 18 by itself represents data because it is a raw numeric fact without meaning until it is connected to context. In Information Systems fundamentals, data is defined as unprocessed facts such as numbers, symbols, or measurements that do not explain their purpose on their own. The number
18 could represent many things: minutes, dollars, items, or a temperature reading. Once the number is connected to the statement baked for 18 minutes, it becomes information because the data has been given context and meaning. Knowledge would involve understanding how baking time interacts with oven type, pizza thickness, or cooking technique, and being able to apply that understanding to adjust cooking when conditions change. Wisdom would involve making the best overall decision, such as considering health, safety, and preventing burning based on real-world judgment. Since the question asks specifically about the value 18 in isolation, it matches the DIKW definition of data as a raw fact. Therefore, the correct answer is data.

The Internet plays two important roles in the business ecosystem:
1.Marketing of products and services: The Internet provides a platform for businesses to promote their products and services globally, reaching a wider audience.
2.Connecting remote employees and offices across wide distances: Through the Internet, remote employees can collaborate, communicate, and work effectively regardless of geographical boundaries.
