How does pipelining improve CPU performance?
- Enhances cache capacity
- Increases clock speed
- Optimizes virtual memory management
- Reduces instruction throughput latency
Pipelining improves CPU performance by reducing instruction throughput latency. It allows multiple instructions to be in different stages of execution simultaneously, thus increasing the overall throughput.
In the realm of HPC, what does "Amdahl's Law" primarily relate to?
- Data compression
- Input/output (I/O) operations
- Memory management
- Parallel processing
"Amdahl's Law" primarily relates to 'parallel processing' in High-Performance Computing (HPC). It quantifies the potential speedup that can be achieved by parallelizing a computation. The law emphasizes that the speedup of a program is limited by the fraction of the code that cannot be parallelized. Understanding Amdahl's Law is essential in optimizing parallel processing in HPC applications.
In the Model-View-Controller (MVC) pattern, the _______ is responsible for presenting data in a specified format to the user.
- Controller
- Database
- Model
- View
In the MVC pattern, the 'View' component is responsible for presenting data to the user in a specified format. It handles the visual representation and user interface aspects of an application.
How do fog computing and edge computing differ in the context of IoT?
- Edge computing focuses on cloud-based data processing, while fog computing utilizes on-device processing.
- Edge computing processes data closer to its source, while fog computing processes data at a central node.
- Fog computing and edge computing are the same in the context of IoT.
- Fog computing is centralized, while edge computing is distributed.
In the context of IoT, 'edge computing' processes data near its source, often at the edge of the network, reducing latency and dependence on centralized servers. 'Fog computing,' on the other hand, is a bit broader and may involve localized processing but can also involve central nodes. This distinction is crucial for IoT applications that require real-time data processing.
A _______ is a database object that automatically triggers specific actions when certain events occur in the database.
- Index
- Procedure
- Trigger
- View
In the context of databases, a 'trigger' is an object that automatically initiates specific actions when predefined events, such as data changes or updates, occur in the database. Triggers help maintain data integrity and enforce business rules.
You are setting up a network for a small business. They want to ensure that even if one of the network paths fails, there will be another path available for data to travel. Which type of routing should you consider implementing?
- Default Routing
- Dynamic Routing
- Load Balancing
- Static Routing
In this scenario, implementing 'Dynamic Routing' is the most suitable choice. Dynamic routing protocols like OSPF or EIGRP allow routers to automatically update routing tables, making it possible for data to take alternative paths in case of network path failures.
Which term describes the long-term direction and the broad aims of an organization's IT?
- IT Governance
- IT Operations
- IT Security
- IT Strategy
'IT Strategy' refers to the long-term direction and the broad aims of an organization's IT. It involves defining how IT can support and align with the overall business goals and objectives.
Which web development approach involves designing a website so it looks and works properly on various devices without requiring a separate version for each device?
- Adaptive Design
- Cross-Browser Compatibility
- Mobile Optimization
- Responsive Design
'Responsive Design' is an approach in web development that focuses on designing websites to adapt to various screen sizes and devices. It ensures that a single version of a website can provide an optimal user experience across different platforms.
In supervised learning, what type of data is used to make predictions?
- Testing data
- Training data
- Unlabeled data
- Validation data
In supervised learning, 'Training data' is used to make predictions. The model learns patterns from this labeled dataset to make predictions on new, unseen data.
In wireless networking, which protocol is specifically designed to secure Wi-Fi networks?
- DNS
- TCP/IP
- WEP (Wired Equivalent Privacy)
- WPA (Wi-Fi Protected Access)
'WPA (Wi-Fi Protected Access)' is a protocol specifically designed to secure Wi-Fi networks. It provides encryption and authentication to protect the confidentiality and integrity of wireless data transmissions.
