Explanation:

Data Center
Organizations maintain data centers to provide centralized data-processing capabilities across the
enterprise. Data centers house and manage large amounts of data. The data center infrastructure
includes hardware components, such as computers, storage systems, network devices, and power
backups; and software components, such as applications, operating systems, and management
software. It also includes environmental controls, such as air conditioning, fire suppression, and
ventilation.
Large organizations often maintain more than one data center to distribute data processing
workloads and provide backup if a disaster occurs.
Five core elements are essential for the functionality of a data center:
Application: A computer program that provides the logic for computing operations
Database management system (DBMS): Provides a structured way to store data in logically
organized tables that are interrelated
Host or compute: A computing platform (hardware, firmware and software) that runs applications
and databases
Network: A data path that facilitates communication among various networked devices
Storage: A device that stores data persistently for subsequent use
These core elements are typically viewed and managed as separate entities, but all the elements
must work together to address data-processing requirements.
