A research institute is working on a complex weather prediction model that requires the simultaneous processing of vast datasets. Which type of computing infrastructure would best suit their needs?
- Grid Computing
- High-Performance Computing (HPC)
- Mainframe Computing
- Quantum Computing
For the processing of vast datasets and complex simulations, 'High-Performance Computing (HPC)' is the ideal choice. It offers exceptional processing power and parallel computing capabilities, making it suitable for tasks like weather prediction models. Mainframes, grid computing, and quantum computing may not provide the necessary performance.
In the context of computer architecture, what does the term "bus" refer to?
- A communication pathway for data
- A high-speed memory
- A system's central processing unit
- A type of storage device
In computer architecture, a "bus" refers to a communication pathway for data, serving as a conduit to transfer data and control signals between different hardware components in a computer system.
_______ is a Cisco proprietary protocol used between switches to maintain a loop-free network.
- ARP
- Internet Control Message Protocol (ICMP)
- Spanning Tree Protocol (STP)
- VLAN Trunking Protocol (VTP)
The 'Spanning Tree Protocol (STP)' is a Cisco proprietary protocol used to prevent and eliminate loops in Ethernet networks. It helps ensure network reliability by maintaining a loop-free topology.
Which algorithmic paradigm solves problems by trying out solutions using one or more models and then adapting based on what works and what doesn't?
- Divide and Conquer
- Dynamic Programming
- Genetic Algorithms
- Greedy Algorithms
'Greedy Algorithms' follow a paradigm where they make locally optimal choices at each step, hoping to find a globally optimal solution. They adapt based on immediate success without considering future consequences.
Which memory type is non-volatile and can be electrically erased and reprogrammed?
- Cache
- EEPROM
- RAM
- ROM
'EEPROM' stands for Electrically Erasable Programmable Read-Only Memory. It is a non-volatile memory type that can be erased and reprogrammed electrically. It is commonly used for storing firmware and configuration data.
Which component of a computer temporarily stores data that the CPU is currently processing or using?
- Hard Drive
- Keyboard
- Monitor
- RAM
RAM (Random Access Memory) is a component of a computer that 'temporarily stores data' that the CPU is currently processing. It provides fast access to data and programs that are in use.
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 (PEMDAS/BODMAS). This means that 'multiplication' is performed before addition, subtraction, and division. It's important to understand these rules for correctly evaluating mathematical expressions in code.
Which protocol is often used for lightweight communication in IoT devices due to its low power consumption?
- FTP (File Transfer Protocol)
- HTTP (Hypertext Transfer Protocol)
- MQTT (Message Queuing Telemetry Transport)
- TCP (Transmission Control Protocol)
MQTT is widely used in IoT because it's designed for low-power, efficient communication. MQTT's publish-subscribe model minimizes overhead and is well-suited for resource-constrained devices.
Which type of penetration testing focuses on testing from an attacker's perspective without prior knowledge of the target infrastructure?
- Black-Box Testing
- Gray-Box Testing
- Vulnerability Scanning
- White-Box Testing
'Black-Box Testing' is a type of penetration testing where testers simulate an attacker with no prior knowledge of the target infrastructure. The goal is to identify vulnerabilities as if they were an external attacker.
Which type of attack involves intercepting and possibly altering communications between two parties without their knowledge?
- DDoS Attack
- Malware
- Man-in-the-Middle Attack
- Phishing
A 'Man-in-the-Middle (MitM) Attack' is a form of cyberattack where an attacker intercepts and possibly alters communications between two parties without their knowledge, compromising data integrity and privacy.
