A _______ is a set of conventions and best practices that dictate how developers should format and style their code to improve readability and maintainability.
- Compiler
- Debugger
- IDE
- Style guide
A 'style guide' is a collection of rules and guidelines that prescribe the coding style and formatting to be followed by developers. It enhances code consistency, readability, and maintainability.
In operating systems, what mechanism provides an interface between users or application programs and the computer hardware?
- Compiler
- Device Drivers
- File System
- Kernel
The 'kernel' serves as the core component of an operating system, providing an interface between user/application programs and the hardware. It manages system resources, scheduling, and hardware communication.
In IoT, devices that directly interact with the physical environment to collect data are called _______.
- Protocols
- Routers
- Sensors
- Servers
In the Internet of Things (IoT), 'sensors' are the devices that directly interact with the physical environment to collect data. They play a crucial role in gathering information for IoT applications.
The concept of providing on-demand network access to shared pools of configurable computing resources is known as _______.
- Big Data
- Cloud Computing
- IoT
- Quantum Computing
'Cloud Computing' is the concept of delivering on-demand access to a shared pool of computing resources over the internet. These resources can be easily configured and scaled to meet various computing needs.
What is the primary purpose of an ERP system?
- Customer Relationship Management
- Employee Time Tracking
- Integrated Business Operations
- Inventory Management
The primary purpose of an 'ERP (Enterprise Resource Planning) system' is to integrate and streamline various business operations, such as finance, production, inventory, and more, to enhance efficiency and decision-making.
In which sorting algorithm are repeated swaps made to bring elements to their correct position, typically visualized like "bubbles" moving up in a fluid?
- Bubble Sort
- Insertion Sort
- Merge Sort
- Quick Sort
'Bubble Sort' is an elementary sorting algorithm that repeatedly steps through the list, compares adjacent elements, and swaps them if they are in the wrong order. The largest unsorted element "bubbles up" to its correct position.
In modern computer systems, the BIOS is stored in _______.
- CD-ROM
- Flash Memory
- Hard Disk Drive (HDD)
- RAM (Random Access Memory)
In modern computers, the BIOS (Basic Input/Output System) is typically stored in 'flash memory,' a non-volatile memory that retains data even when the power is off.
An organization is looking to understand the correlation between various metrics in their dataset. Which type of visualization would best represent pairwise relationships among multiple variables?
- Bar Chart
- Heatmap
- Pie Chart
- Scatter Plot Matrix
A Scatter Plot Matrix is an effective visualization for understanding the pairwise relationships and correlations between multiple variables. It allows you to see how different metrics relate to each other.
In the context of neural networks, the function used to quantify how far the predicted output is from the actual output is termed as _______.
- Activation Function
- Cost Function
- Gradient Descent
- Loss Function
In neural networks, the term you're looking for is the 'Loss Function.' This function quantifies the difference between the predicted output and the actual output, helping the network learn and improve its predictions during training.
A company has sensitive data they want to transfer over the internet. They decide to use a VPN. What is the primary benefit of this approach in terms of network security?
- Data Compression
- Enhanced Performance
- Lower Latency
- Secure and Encrypted Data Transfer
The primary benefit of using a VPN (Virtual Private Network) for transferring sensitive data is the 'secure and encrypted data transfer.' A VPN creates a secure tunnel for data to pass through, ensuring that data is encrypted and protected from interception during transmission.
