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.
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.
_______ is a virtualization technology focused on running multiple instances or copies of an application on a single set of hardware resources.
- Containerization
- Firewall
- Hyperconvergence
- Virtual Private Network (VPN)
'Containerization' is a virtualization technique that allows running multiple instances or copies of applications on the same hardware, isolated from each other. Containers share the same OS kernel and use fewer resources.
What SQL clause is used to filter the results of a query based on a specified condition?
- GROUP BY
- ORDER BY
- SELECT
- WHERE
The 'WHERE' clause in SQL is used to filter the results of a query based on a specified condition. It allows you to retrieve specific data that meets certain criteria.
You have a list of tasks to complete, some of which depend on others being completed first. You want to determine a sequence to complete the tasks such that all dependencies are honored. What algorithmic approach would be most suitable?
- Greedy Algorithm
- Merge Sort
- Quick Sort
- Topological Sorting
To determine a task sequence while honoring dependencies, 'Topological Sorting' is the most appropriate approach. It is commonly used in project scheduling and task management to create a linear order of tasks in a directed acyclic graph (DAG) while ensuring all dependencies are met.
_______ is a small-sized, high-speed volatile computer memory that provides high-speed data access to the processor and stores frequently used computer programs, applications, and data.
- Cache
- Hard Drive
- RAM
- ROM
'Cache' is a type of high-speed, volatile memory used to store frequently accessed data and instructions, allowing for faster data retrieval by the processor. It acts as a bridge between slower memory (like RAM) and the processor, enhancing system performance.
Which HTTP status code indicates that the server successfully processed the request, but is not returning any content?
- 200 OK
- 204 No Content
- 404 Not Found
- 500 Internal Server Error
The '204 No Content' status code indicates that the server successfully processed the request but is not returning any additional content in the response body. It's often used for operations that have no response data.
