In IT project management, what technique visualizes tasks or activities on a board, allowing team members to track project progress?
- Critical Path Method (CPM)
- Gantt Chart
- Kanban
- Waterfall Method
The technique that visualizes tasks on a board for easy tracking is 'Kanban.' Kanban is widely used in Agile project management, allowing teams to manage work in progress effectively and optimize flow.
In wireless networks, what does the term "SSID" stand for?
- Secure System Identifier
- Signal Strength Indicator
- Service Set Identifier
- Subnet Specification
"SSID" stands for "Service Set Identifier" (Option c). It is a unique name used to identify a wireless network. When connecting to a Wi-Fi network, users select the network with the matching SSID. This helps users distinguish between different networks.
In ITSM, a _______ is a standard or set of guidelines for how something might be accomplished, but without mandating a particular tool or method.
- Best Practice
- Change Request Form
- Process Model
- Service Catalog
In IT Service Management (ITSM), a 'best practice' refers to a standard or set of guidelines for achieving a specific objective or task effectively. It provides recommendations and proven methods, but it doesn't require the use of a particular tool or approach. A Process Model outlines how a specific process works, a Service Catalog lists available services, and a Change Request Form is used to request changes in IT services.
The concept of providing a dedicated portion of a public cloud environment exclusively for a single tenant is called _______.
- Cloud Bursting
- Multi-Tenancy
- Single-Tenancy
- Virtualization
Single-Tenancy refers to the practice of allocating a dedicated portion of a public cloud for a single tenant or organization, providing isolation and control over resources.
The concept in ERP where data is entered once and is then accessible from multiple applications without redundancy is referred to as _______.
- Data Aggregation
- Data Duplication
- Data Integration
- Data Normalization
The concept described is 'Data Integration' in ERP. It ensures that data is entered once and can be accessed by multiple applications without duplication. This enhances data accuracy and consistency across the organization.
In app development, the method of delivering updates to only a portion of the app's user base to test changes before a full release is known as _______.
- A/B testing
- Alpha testing
- Beta testing
- Canary testing
A/B testing, or "split testing," is a method where different versions of an application are released to different user groups. It's a technique used to assess the impact of changes before a full release.
A neural network with three or more layers (input, output, and one or more hidden layers) is termed as a __________.
- Deep Learning Network
- Feedforward Network
- Perceptron
- Recurrent Network
A neural network with three or more layers, including input, output, and one or more hidden layers, is termed as a "Deep Learning Network." Deep networks are known for their ability to model complex relationships.
In deep learning, when the internal states of a neural network capture necessary information about previous time steps, it is particularly referred to as _______.
- Backpropagation
- Convolutional Layer
- Long Short-Term Memory
- Recurrent Neural Network
The term you're referring to is 'Recurrent Neural Network' (RNN). RNNs are designed to capture information from previous time steps, making them suitable for sequential data tasks like natural language processing and time series analysis.
When visualizing data with a large number of categories, a _______ chart can help in displaying the data in a compact and organized manner.
- Bar
- Line
- Pie
- Treemap
For data visualization with many categories, a 'Treemap' chart is useful. It displays hierarchical data in a compact way, with nested rectangles representing different categories.
In object-oriented programming, what concept involves hiding the internal states and requiring all interaction to be performed through well-defined interfaces?
- Abstraction
- Encapsulation
- Inheritance
- Polymorphism
'Encapsulation' is a key concept in object-oriented programming that involves bundling the internal state and methods into a single unit (a class) and allowing interaction through well-defined interfaces, thus hiding implementation details.
