Which programming construct allows the execution of a block of code multiple times based on a condition?
- Array
- Function
- Loop
- Pointer
In programming, a 'loop' is a control structure that allows you to execute a block of code repeatedly as long as a certain condition is met. This is commonly used for repetitive tasks in coding.
Which cryptographic attack involves trying every possible key until the correct one is found?
- Brute Force Attack
- DDoS Attack
- Man-in-the-Middle
- SQL Injection
A 'Brute Force Attack' is an approach where an attacker tries every possible key or combination until the correct one is found. It's used to crack passwords, encryption, or authentication mechanisms.
In most programming languages, which arithmetic operation is performed first if no parentheses are used?
- Addition
- Division
- Multiplication
- Subtraction
In the absence of parentheses, most programming languages follow the order of operations, and 'multiplication' is performed before addition, subtraction, and division.
Which design principle suggests that objects should be open for extension but closed for modification?
- Abstraction
- Inheritance
- Open-Closed Principle
- Polymorphism
The 'Open-Closed Principle' is a fundamental design principle in object-oriented programming. It suggests that software entities (such as classes) should be open for extension (new functionality can be added) but closed for modification (existing code remains unchanged). This encourages modularity and maintainability.
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.
In which switching method is the entire frame stored before it is forwarded to its destination?
- Circuit Switching
- Message Switching
- Packet Switching
- Store-and-Forward
Store-and-Forward switching is a method where the entire data frame is received and stored before being forwarded to its destination. This method allows for error checking and can help prevent network congestion.
Which method in NLP helps in reducing the dimensionality of word vectors while retaining most of the important information?
- Dimensionality Reduction
- Latent Semantic Analysis (LSA)
- Neural Networks
- Word Embedding
'Latent Semantic Analysis (LSA)' is a technique in NLP that reduces the dimensionality of word vectors while preserving important semantic information. It's a method used for semantic analysis and text retrieval.
In the context of digital transformation, which term refers to the redesign of business processes, often involving the integration of advanced digital technologies?
- Agile Transformation
- Business Process Reengineering (BPR)
- DevOps (Development and Operations)
- Waterfall Methodology
'Business Process Reengineering (BPR)' refers to the significant redesign of business processes to achieve improvements in efficiency, effectiveness, and often involves integrating advanced digital technologies to streamline and enhance operations.
