In mobile app development, the _______ is a tool used for designing and testing the user interface of an app.
- API (Application Programming Interface)
- IDE (Integrated Development Environment)
- ORM (Object-Relational Mapping)
- SDK (Software Development Kit)
In mobile app development, an 'IDE' (Integrated Development Environment) is a comprehensive tool that helps developers design, code, and test the user interface and functionality of their apps.
What is the primary purpose of the training phase in machine learning?
- Data prediction and classification
- Feature extraction and selection
- Model evaluation and testing
- Model parameter adjustment
The primary purpose of the training phase in machine learning is 'Model parameter adjustment.' During training, the model adjusts its parameters to fit the data, aiming to minimize the error between predicted and actual values.
Which type of neural network architecture is particularly effective for sequence-to-sequence tasks, such as language translation?
- Autoencoders
- Convolutional Neural Networks (CNNs)
- Generative Adversarial Networks (GANs)
- Recurrent Neural Networks (RNNs)
Recurrent Neural Networks (RNNs) are particularly effective for 'sequence-to-sequence' tasks. They are widely used in tasks like language translation and speech recognition. The ability to maintain context from previous time steps allows RNNs to generate meaningful sequences, making them suitable for these tasks.
A software development team finds that they spend a significant amount of time fixing bugs in the week following each release. Which software engineering practice could help them identify and address issues earlier in the development process?
- DevOps
- Pair Programming
- Scrum
- Test-Driven Development (TDD)
Test-Driven Development (TDD) involves writing tests before writing code. By writing tests first, developers can identify and address issues early in the development process, ensuring that code is more reliable and bug-free before it's integrated into the codebase.
What is the primary purpose of an ORM (Object-Relational Mapping) in application development?
- Displaying graphics
- Managing user accounts
- Mapping objects to databases
- Playing audio
The primary purpose of an ORM is to map objects in your application to the tables and records in a relational database. It simplifies database interactions and allows you to work with data in an object-oriented manner.
A company wants to analyze customer reviews to improve product features. Which NLP technique would be most appropriate to extract specific product features mentioned in the reviews?
- Document Classification
- Named Entity Recognition (NER)
- Sentiment Analysis
- Tokenization
Named Entity Recognition (NER) is a technique in Natural Language Processing (NLP) that identifies and extracts specific entities such as product names, locations, and more. It's ideal for extracting product features from text data.
In the context of intrusion detection, what does "false positive" refer to?
- Inactive System
- Legitimate Activity
- Successful Intrusion
- System Patched
A 'false positive' in intrusion detection occurs when the system incorrectly identifies legitimate activity as a security threat or intrusion attempt. It can lead to unnecessary alerts.
In cryptography, the process of disguising plaintext to hide its content is called _______.
- Compression
- Decryption
- Encryption
- Steganography
The blank should be filled with "Steganography." Steganography is the practice of concealing data within other data, making it appear as if the hidden information doesn't exist, enhancing security and confidentiality.
The practice of using technology to innovate business practices, customer experiences, and culture is known as _______ transformation.
- Cultural
- Digital
- Innovation
- Technological
Digital transformation involves using technology to fundamentally change and improve business processes, customer interactions, and organizational culture. It's about leveraging digital tools to drive innovation and stay competitive.
The section of the operating system that chooses which task will be performed by the system at any given time is known as the _______.
- Compiler
- File System
- Kernel
- Scheduler
The 'scheduler' is a crucial part of the operating system that determines the order and priority in which tasks are executed, ensuring efficient resource allocation.
