What is the primary purpose of a network switch in a local area network (LAN)?
- Connect devices
- Connect to the internet
- Provide wireless access
- Store data temporarily
A network switch primarily serves to 'connect devices' within a local area network (LAN). It intelligently forwards data to the appropriate device based on the device's MAC address, improving network efficiency.
In HPC, what is the primary purpose of using parallel processing techniques?
- Enhancing data security
- Minimizing software complexity
- Reducing hardware costs
- Speeding up individual tasks
Parallel processing in High-Performance Computing (HPC) aims to 'speed up individual tasks' by breaking them into smaller sub-tasks that can be processed simultaneously on multiple processors, increasing overall computation speed.
Which approach in ERP involves tailoring the software to fit the specific needs and processes of an organization, often leading to longer implementation times?
- Configuration
- Customization
- Off-the-shelf
- Standardization
The approach of 'customization' in ERP entails tailoring the software to meet specific organizational needs. This can lead to longer implementation times but results in a more tailored solution.
What cryptographic technique allows multiple parties to compute a function over their inputs while keeping those inputs private?
- Digital Signatures
- Public Key Infrastructure (PKI)
- Secure Multi-Party Computation
- Zero-Knowledge Proof
Secure Multi-Party Computation (SMPC) is a cryptographic technique that enables multiple parties to jointly compute a function over their inputs while ensuring the privacy of those inputs. It's used in scenarios where data privacy is crucial, such as collaborative data analysis without revealing individual data points.
One of the pillars of IT governance is ensuring that IT resources are used responsibly, efficiently, and _______.
- Effectively
- Innovatively
- Securely
- Transparently
In IT governance, one of the pillars is to ensure that IT resources are used responsibly, efficiently, and 'transparently.' This means that actions and decisions related to IT should be clear and open to scrutiny, promoting accountability and trust.
Which module in an ERP system typically manages human resources, payroll, and benefits?
- Finance Module
- HR Module
- Inventory Module
- Sales Module
The 'HR (Human Resources) Module' in an ERP system is responsible for managing various aspects of an organization's human resources, including payroll, employee benefits, and personnel data. It helps streamline HR-related processes.
Which RAID level provides disk mirroring for fault tolerance without striping?
- RAID 0
- RAID 1
- RAID 10
- RAID 5
RAID 1, also known as disk mirroring, is a RAID level that provides fault tolerance by duplicating data on two or more disks. It doesn't involve striping, making it a reliable choice for data redundancy.
High-Performance Computing (HPC) is commonly associated with which type of processing?
- Everyday computing tasks
- Scientific and data-intensive tasks
- Simple mathematical calculations
- Social media management
High-Performance Computing (HPC) is associated with "scientific and data-intensive tasks." These tasks involve complex simulations, modeling, and data analysis that require immense computational power, often beyond the capability of regular computers.
Which activation function in neural networks maps its input to values between 0 and 1?
- Leaky ReLU
- ReLU (Rectified Linear Unit)
- Sigmoid
- Tanh (Hyperbolic Tangent)
The activation function that maps its input to values between 0 and 1 is the 'Sigmoid' function. It's commonly used in the output layer of a neural network for binary classification tasks, where it represents probabilities.
You're developing a web application where performance is a critical concern. Which technique would be most suitable for reducing the load times of your web pages?
- Content Delivery Networks (CDNs)
- Object-Oriented Programming
- Static Code Analysis
- Waterfall Model
Content Delivery Networks (CDNs) are crucial for optimizing web page load times. CDNs distribute content to servers closer to the user, reducing latency and speeding up page loading. They cache assets and reduce the load on the origin server, improving performance.
