NEW QUESTION # 95
Based on an analysis of a company's needs, a database should be installed so that data resides on different machines, often in entirely different locations. What is the name of the database that satisfies this need?

Answer: B

Explanation:
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.


NEW QUESTION # 96
What type of database uses parent-child relationships?

Answer: C

Explanation:
Hierarchical databases use a parent-child relationship model. In this type of database, data is organized into a tree-like structure that implies a single-parent for each record. This model allows the representation of data in a hierarchy which is very much like a family tree. Each parent can have multiple children, but each child has only one parent (also known as a one-to-many relationship).
The hierarchical database model was one of the first database models, historically used with mainframe computers. In this model, records contain information about their groups of parent/child relationships, similar to a family tree. If we consider a database of employees,each department would be a parent node, and each employee within that department would be a child node of the department.
References: The concept of parent-child relationships in databases is well-established and discussed in various educational resources and forums. For example, Stack Overflow provides explanations of how these relationships work in practice12. Additionally, other resources like phoenixnap.com explain how these relationships are established in databases3.


NEW QUESTION # 97
Which category of software allows other types of software to interface with the computer hardware?

Answer: B

Explanation:
System software is the category that allows other software to interface with computer hardware. In Information Technology, system software includes the operating system, device drivers, and utility programs that manage hardware resources and provide a platform for applications. Applications such as word processors and web browsers do not communicate directly with hardware like the CPU, memory, storage devices, or printers. Instead, they use services provided by the operating system and drivers. The operating system manages processes, memory, and input and output operations, while device drivers translate general commands into device-specific instructions for hardware components. This layered design improves reliability and security by controlling access to hardware and standardizing how applications request resources. Productivity software refers to applications that help users perform tasks, and collaboration software supports communication and teamwork, but neither category provides the core hardware interface.
Shareware is a distribution and licensing model, not a hardware interface layer. Therefore, the correct category is system software.
