Computers Networking

What is the purpose of a router in a computer network?

• To forward data packets between computer networks.

• To cook data packets

• To water plants in the network

• To play music between computer networks

Explain the difference between LAN and WAN.

• LAN is more secure than WAN.

• LAN is used for long-distance communication, while WAN is used for short-distance communication.

• LAN is a local network connecting devices within a limited area, while WAN is a wide network connecting devices over a large geographical area.

• LAN is a wireless network, while WAN is a wired network.

What is an IP address and why is it important in networking?

• IP addresses are randomly assigned and have no specific purpose in networking.

• IP addresses are irrelevant in networking and do not impact data transmission.

• An IP address is important in networking because it allows devices to be uniquely identified and enables data packets to be routed to the correct destination across the network.

• An IP address is used for physical device identification only.

What is the function of a firewall in network security?

• Firewalls are designed to prevent all network traffic

• The function of a firewall in network security is to monitor and control incoming and outgoing network traffic based on predetermined security rules.

• Firewalls are only effective for wired networks

• Firewalls are used to increase network speed

Describe the concept of bandwidth in networking.

• Bandwidth is the measure of network latency.

• Bandwidth refers to the number of devices connected to a network.

• Bandwidth is the physical width of a network cable.

• Bandwidth in networking refers to the maximum rate of data transfer across a network path.

What is the role of DNS in the context of networking?

• DNS manages network hardware configurations.

• DNS is responsible for encrypting network traffic.

• DNS translates domain names into IP addresses.

• DNS monitors network bandwidth usage.

What are the advantages of using Ethernet over Wi-Fi in a network?

• Ethernet provides faster and more reliable connection speeds, lower latency, and more secure connections compared to Wi-Fi.

• Ethernet is less secure compared to Wi-Fi.

• Wi-Fi offers faster speeds and lower latency than Ethernet.

• Wi-Fi connections are more reliable than Ethernet.

Discuss the importance of network protocols in communication.

• Network protocols hinder device compatibility

• Network protocols are crucial in communication to standardize processes, ensure accurate data transmission, and enable devices to understand each other's signals.

• Network protocols can lead to data corruption

• Network protocols are unnecessary in communication

What is a network topology?

• A network topology is the speed of internet connection.

• A network topology is the color scheme used in network design.

• A network topology is the layout pattern of interconnections between devices in a network.

• A network topology is the type of computer hardware used in a network.

What is the purpose of network protocols?

• To control the weather patterns

• To govern communication between devices on a network.

• To predict the stock market

• To bake cookies
