D322 Introduction to IT - Set 4 - Part 2

Correct Answer: PaaS

Platform as a Service (PaaS) provides developers with the tools and environments necessary to build, test, and deploy applications.

Correct Answer: Python

Python is a versatile programming language widely used in artificial intelligence (AI) and machine learning due to its simplicity and extensive libraries.

Correct Answer: To speed up data retrieval

A database index improves the speed of data retrieval operations by allowing the database to find records faster.

Correct Answer: Organizes data using a tree-like structure with parent-child relationships

A hierarchical database organizes data in a tree-like structure, where each record has one parent and possibly multiple children.

Correct Answer: To forward data only to the intended recipient

A network switch forwards data only to the intended recipient within a local network, improving efficiency and security.

Correct Answer: Scalability and flexibility

Cloud computing offers businesses scalability and flexibility, allowing them to adjust resources according to their needs without investing in physical infrastructure.

Correct Answer: To secure data by converting it into an unreadable format

Encryption is the process of converting data into an unreadable format to protect it from unauthorized access during transmission or storage.

Correct Answer: Java

Java is a compiled language, meaning the code is translated into machine language by a compiler before it can be executed.

Correct Answer: SSH

SSH (Secure Shell) is a command-line interface used to securely communicate with remote servers, encrypting data during transmission.

Correct Answer: Open-source software

Open-source software allows users to access, modify, and redistribute the source code, fostering collaboration and innovation.

Correct Answer: IaaS

Infrastructure as a Service (IaaS) allows businesses to rent computing infrastructure resources, such as virtual machines and storage, over the internet.

Correct Answer: Modularization

Modularization involves dividing a program into separate modules or components that can be reused in different parts of the program, improving efficiency and maintainability.

Correct Answer: Databases are used for day-to-day operations, while data warehouses are used for analytics

Databases are used for day-to-day transactions and operations, while data warehouses store large volumes of data specifically for analysis and reporting.

Correct Answer: Phishing

Phishing attacks involve tricking users into providing sensitive information, such as passwords or credit card numbers, through deceptive emails or websites.

Correct Answer: Compiled language

In compiled languages, the entire program is translated into machine code before it is executed, allowing the program to run without further translation.

Correct Answer: ROM

ROM (Read-Only Memory) is non-volatile, meaning it retains its data even when the power is turned off, unlike RAM.

Correct Answer: The creation of virtual machines that run on a single physical machine

Virtualization in cloud computing refers to creating virtual machines that run on a single physical machine, enabling efficient use of hardware resources.

Correct Answer: Primary Key

A primary key is a unique value that identifies a record in a database table, ensuring that no two records have the same identifier.

Correct Answer: Bus

In a bus topology, all devices are connected to a single cable that serves as the communication backbone.

Correct Answer: PaaS

Platform as a Service (PaaS) provides users with the tools and environments to develop, test, and deploy applications without the need to manage the underlying infrastructure.
