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 designed for the management of multicast group memberships and operates at the Network layer?
- ARP (Address Resolution Protocol)
- IGMP (Internet Group Management Protocol)
- OSPF (Open Shortest Path First)
- SMTP (Simple Mail Transfer Protocol)
IGMP, or Internet Group Management Protocol, is specifically designed for the management of multicast group memberships. It operates at the Network layer of the OSI model and is used by routers to learn about active multicast groups on a network.
The process of repeatedly merging code from different team members into a shared mainline to prevent integration problems is known as _______.
- Code Deployment
- Continuous Integration
- Parallel Development
- Version Control
Continuous Integration (CI) is the practice of merging code frequently into a shared repository to ensure early detection of integration problems and maintain code quality throughout the development process.
In terms of information assurance, what practice ensures that only authorized modifications are made to an organization's assets?
- Change Management
- Data Encryption
- Firewall Configuration
- Intrusion Detection
Change Management is a crucial practice in information assurance that ensures that only authorized modifications are made to an organization's assets, including hardware, software, and data. It involves a structured process of requesting, reviewing, and approving changes to maintain system integrity and security.
What technique do threat actors use to exploit human psychology, rather than technical vulnerabilities, to gain unauthorized access or information?
- Encryption
- Firewall
- Intrusion Detection System (IDS)
- Phishing
'Phishing' is a technique where threat actors use social engineering to manipulate human psychology and trick individuals into revealing sensitive information or granting unauthorized access.
