Understanding Network Components

What is the primary function of a Network Interface Card (NIC)?

• To provide power to the device.

• To increase the speed of the internet connection.

• To store data for the device.

• To connect a device to a network and facilitate communication.

How does a NIC connect a computer to a network?

• A NIC connects a computer to a network by providing power to the device.

• A NIC connects a computer to a network by encrypting all data before transmission.

• A NIC connects a computer to a network by converting digital data into network signals and facilitating communication through network protocols.

• A NIC connects a computer to a network by storing data in a local database.

What are the two main types of Network Interface Cards?

• Analog and Digital

• Static and Dynamic

• Local and Remote

• Wired and Wireless

What is the difference between a modem and a router?

• A modem and a router are the same device used interchangeably.

• A modem is used for Wi-Fi; a router connects to the ISP.

• A modem distributes the internet connection; a router connects to the ISP.

• A modem connects to the ISP; a router distributes the internet connection to multiple devices.

Which device is responsible for connecting to the Internet?

• Switch

• Access Point

• Modem or Router

• Network Cable

How does a router manage data traffic in a network?

• A router encrypts data packets to secure them during transmission.

• A router directs data packets between devices in a network by using routing tables and protocols to manage traffic efficiently.

• A router only connects devices to the internet without managing traffic.

• A router acts as a firewall to block all incoming data traffic.

What role does a modem play in data transmission?

• A modem stores data for future use.

• A modem amplifies signals for better reception.

• A modem acts as a firewall to protect networks.

• A modem facilitates data transmission by converting digital signals to analog and vice versa.

Can a modem function without a router? Why or why not?

• A modem requires a router to provide internet access to devices.

• Yes, a modem can function without a router.

• A modem and a router are the same device, so one cannot work without the other.

• A modem cannot function without a router because it needs a network to connect to.

What is the purpose of IP addresses in a network?

• To encrypt data transmitted over the network.

• To uniquely identify devices on a network and facilitate communication between them.

• To provide internet access to all devices.

• To assign bandwidth limits to devices.

How do routers determine the best path for data transmission?

• Routers randomly select paths without any criteria.

• Routers rely solely on user input for path selection.

• Routers use only the physical distance to determine the best path.

• Routers determine the best path using routing algorithms and metrics like hop count and bandwidth.
