The correct answer for this question is 'nerve center' because the control unit in a digital computer plays a similar role to the central nervous system in the human body. It is responsible for coordinating and controlling the activities of the computer's components, just like how the central nervous system controls the functions of the body. Therefore, referring to the control unit as the 'nerve center' highlights its crucial role in managing the computer's operations.
The correct answer for this question is 'Polymorphic virus' because a polymorphic virus is a type of malware that can change its code each time it is installed, making it difficult for antivirus software to detect and remove. This ability to constantly alter its appearance allows the virus to evade detection and continue infecting systems.
The correct answer for this question is 'Cloud Computing' because it specifically refers to the delivery of computing services over the internet. This technology allows users to access and use resources such as storage, applications, and processing power remotely, without the need for physical infrastructure. Therefore, 'Cloud Computing' fits the description of performing computation, storage, and applications as a service across a network.
The correct answer for this question is 'D. none' because RAM (Random Access Memory) is not an example of any specific category or type.

The correct answer for this question is 'Common Business Oriented Language' because COBOL is a high-level programming language that was specifically designed for business applications. It is known for its readability and ease of use in developing programs for business data processing. Therefore, 'Common Business Oriented Language' accurately reflects the purpose and focus of COBOL as a programming language.
The correct answer for this question is 'D. programming language' because a programming language is a specific set of rules and syntax used to communicate instructions to a computer. It is designed to provide a structured way for programmers to write code that the computer can understand and execute. Therefore, a programming language is the most appropriate term to describe a set of rules for telling the computer what operations to perform.
