Which type of database is designed to store data in key-value pairs?
- Columnar Database
- Graph Database
- NoSQL Database
- Relational Database
NoSQL databases are designed to store data in various formats, including key-value pairs. They are suitable for handling unstructured or semi-structured data and are often used in modern web and big data applications.
Web pages that can change content dynamically without requiring the page to be fully reloaded are often referred to as _______.
- AJAX pages
- Cookies
- Dynamic pages
- Static pages
Web pages that can change content dynamically without a full page reload are often referred to as 'AJAX pages.' AJAX stands for Asynchronous JavaScript and XML, and it allows for seamless, dynamic content updates in web applications.
In wireless networking, the method used to spread communication signals across available bandwidths to enhance data throughput is called _______.
- Encryption
- Latency Reduction
- Modulation
- Multiplexing
Multiplexing is the technique of spreading multiple communication signals across available bandwidth to increase data throughput and efficiency in wireless networks.
Company wants to analyze images to detect defects in products on an assembly line. Which type of neural network would be most suitable for this task?
- Convolutional Neural Network (CNN)
- Deep Q-Network (DQN)
- Generative Adversarial Network (GAN)
- Recurrent Neural Network (RNN)
For image analysis and object detection tasks, a 'Convolutional Neural Network (CNN)' is the most suitable choice. CNNs are designed to effectively process grid-like data, making them ideal for tasks like defect detection in images. They excel at identifying patterns and features in images.
In a hybrid cloud environment, what mechanism ensures secure data transmission between on-premises data centers and the cloud?
- Cloud-based firewall
- Data encryption
- Intrusion Detection System (IDS)
- Virtual Private Network (VPN)
In a hybrid cloud environment, a 'Virtual Private Network (VPN)' is commonly used to ensure secure data transmission between on-premises data centers and the cloud. VPNs create encrypted communication tunnels over the public internet, enhancing security. Data encryption alone may not secure the entire transmission path.
The technology that enables one physical piece of hardware to function as multiple "logical" devices is known as _______.
- Cloud Computing
- Firewall
- Mainframe
- Virtualization
The technology that enables one physical piece of hardware to function as multiple "logical" devices is called 'Virtualization.' It abstracts and isolates resources for efficient use.
A security measure where multiple layers of defense are placed throughout an information technology system is known as _______.
- Antivirus
- Defense-in-Depth
- Encryption
- Firewall
Defense-in-Depth is a comprehensive security strategy that involves implementing multiple layers of defense mechanisms to protect an IT system, making it more resilient to various threats and attacks.
Which type of virtualization allows multiple operating systems to run on a single physical machine?
- Application Virtualization
- Cloud Virtualization
- Hypervisor Virtualization
- Network Virtualization
Hypervisor virtualization allows multiple operating systems (OS) to run on a single physical machine simultaneously. A hypervisor, also known as a virtual machine monitor, manages and allocates resources to each virtualized OS, enabling efficient utilization of hardware resources and facilitating tasks like testing different OS environments on a single server.
In computer architecture, what is the role of the control unit?
- Executes arithmetic operations
- Manages computer peripherals
- Manages instruction execution
- Stores data temporarily
In computer architecture, the 'control unit' is responsible for managing instruction execution. It fetches, decodes, and coordinates the execution of instructions, ensuring the proper flow of data and control within the CPU.
In the realm of information assurance, which process ensures that data has not been altered during transmission?
- Data Authentication
- Data Compression
- Data Encryption
- Data Integrity Check
Data Integrity Check ensures that data remains unaltered during transmission. This is typically achieved through methods like checksums or hash functions, which detect any changes in data.
