Computer Science Challenge for Grade 10

What is an algorithm?

• A random guess about a problem.

• A recipe for cooking a dish.

• An algorithm is a step-by-step procedure for solving a problem.

• A collection of data points without a process.

Explain the difference between a compiler and an interpreter.

• A compiler executes code directly, while an interpreter does not.

• A compiler is used for scripting languages, while an interpreter is used for compiled languages.

• A compiler translates the entire code at once, while an interpreter translates code line-by-line during execution.

• A compiler translates code line-by-line, while an interpreter translates the entire code at once.

What is the purpose of flowcharts in programming?

• The purpose of flowcharts in programming is to visually represent the flow of control and data in a program.

• To create a detailed code documentation.

• To replace the need for actual coding.

• To serve as a debugging tool for syntax errors.

Define the term 'IP address'.

• A physical device that connects multiple networks.

• A type of software used for managing network traffic.

• An IP address is a unique numerical label assigned to each device on a network, used for identifying and locating the device.

• A method for encrypting data on a network.

What are the main components of a computer network?

• Devices, transmission media, and network protocols.

• Power supply, cooling systems, and hardware components.

• Software applications, user interfaces, and databases.

• Routers, switches, and firewalls.

What is the function of a router in a network?

• To store data packets for later retrieval.

• To amplify the signal strength in a network.

• The function of a router in a network is to direct data packets between different networks.

• To provide a physical connection between devices.

Describe the concept of client-server architecture.

• Client-server architecture is a decentralized model where clients operate independently.

• Client-server architecture is a model where all processing is done on the client side.

• Client-server architecture is a model where clients request services from centralized servers that provide resources and processing.

• Client-server architecture eliminates the need for a server entirely.

What is the difference between TCP and UDP?

• TCP is reliable and connection-oriented; UDP is faster and connectionless.

• TCP is faster and connectionless; UDP is reliable and connection-oriented.

• UDP guarantees delivery of packets; TCP does not.

• TCP and UDP are both connection-oriented protocols.

Explain what a firewall does in network security.

• A firewall monitors and controls network traffic to protect against unauthorized access and cyber threats.

• A firewall is used to store data securely.

• A firewall is a type of antivirus software.

• A firewall only speeds up network connections.

What is the significance of data encapsulation in programming?

• Data encapsulation reduces code complexity by eliminating functions.

• Data encapsulation enhances security, modularity, and maintainability in programming.

• Data encapsulation is primarily used for optimizing performance.

• Data encapsulation allows direct access to all data members.
