Final answer:
Coaxial cables are used to transmit data with minimal interference, Intranets are private internal networks using internet protocols, records and files are components of data management, a DBMS organizes and queries data, and malicious software includes viruses, worms, Trojans, and ransomware. Virtualization allows multiple virtual systems to run on a single physical server.
This correct answer b
Step-by-step explanation:
Coaxial Cable Usage
Coaxial cable is primarily used for the transmission of radio frequency signals for internet connections, cable television, and other data networks. Its construction allows it to carry signals with minimal interference from external electromagnetic fields.
Intranet Definition
An Intranet is a private network that is contained within an enterprise. It uses standard internet protocols, network connectivity and is accessible only by the organization's members, employees, or others with authorization.
Record and File in Data Management
In data management, a record is a collection of related fields that usually represents a single entity, such as a customer or a transaction. A file is a collection of records that are typically stored and accessed together.
Database Management System (DBMS)
A Database Management System (DBMS) is software that uses a standard method of cataloging, retrieving, and running queries on data. It manages incoming data, organizes it, and provides ways for the data to be modified or extracted by users or other programs.
Malicious Software Examples
Virus
Worm
Trojan Horse
Ransomware
Virtualization Diagram
Before virtualization, a single physical server runs a single operating system and a single application. After virtualization, that same server can run multiple virtual machines, each with its own operating system and application, leading to improved resource utilization and isolation between applications.
