Understanding the Role of a Router

Which of the following best describes the main function of a router in a network?

A It connects multiple networks and directs data packets between them.

B It connects devices within the same network and forwards data based on MAC addresses.

C It stores data and manages file access for network users.

D It provides wireless access to devices without using cables.

💡 Hint

Think about how data moves between different networks, like between your home and the internet.

A router connects different networks and decides the best path for data packets to travel between them. Switches connect devices within the same network.

Switch Functionality in a Network

What is the primary role of a network switch?

A To connect different networks and route data between them.

B To encrypt data for secure transmission.

C To assign IP addresses to devices automatically.

D To connect devices within the same network and forward data based on MAC addresses.

💡 Hint

Think about how devices in your home connect to each other using cables.

A switch connects devices within the same local network and forwards data based on hardware (MAC) addresses.

Data Packet Flow Through Router and Switch

Consider a data packet sent from a computer in Network A to a computer in Network B. The packet passes through a switch and then a router. Which sequence correctly shows how the packet is handled?

A Switch reads MAC address → forwards to router → Router reads IP address → sends to destination

B Router reads MAC address → forwards to switch → Switch reads IP address → sends to destination

C Router reads IP address → forwards to switch → Switch reads IP address → sends to destination

D Switch reads IP address → forwards to router → Router reads MAC address → sends to destination

💡 Hint

Remember that switches use MAC addresses and routers use IP addresses.

Switches forward data based on MAC addresses within the local network. Routers use IP addresses to send data between networks.

Identifying Device by Function

You see a device that connects multiple devices in the same office and forwards data only to the device that needs it. What device is this?

A Modem

B Switch

C Router

D Firewall

💡 Hint

Think about a device that directs data inside the same network.

A switch connects devices within the same network and forwards data only to the intended recipient using MAC addresses.

❓ Comparison

Comparing Router and Switch Functions

Which statement correctly compares routers and switches?

A Routers connect devices within the same network; switches connect different networks.

B Switches use IP addresses to forward data; routers use MAC addresses.

C Routers direct data between networks using IP addresses; switches forward data within a network using MAC addresses.

D Both routers and switches perform the same function but use different cables.

💡 Hint

Focus on the type of addresses each device uses to forward data.

Routers use IP addresses to route data between networks. Switches use MAC addresses to forward data within the same network.
