Computer Network Devices and Connectivity

What are the different types of computer network devices?

• routers, switches, hubs, modems, network interface cards (NICs), and wireless access points

• printers, scanners, keyboards, monitors

• operating systems, software applications, antivirus programs

• hard drives, RAM, processors, graphics cards

What is the function of a switch in a computer network?

• The function of a switch in a computer network is to connect devices and forward data packets.

• The function of a switch in a computer network is to encrypt data packets.

• The function of a switch in a computer network is to slow down the connection between devices.

• The function of a switch in a computer network is to block data packets.

How does a router work in a computer network?

• A router blocks data packets between computer networks.

• A router stores data packets between computer networks.

• A router forwards data packets between computer networks.

• A router encrypts data packets between computer networks.

What is the main difference between a hub and a switch?

• A hub operates at the physical layer and broadcasts data to all connected devices, while a switch operates at the data link layer and selectively forwards data based on MAC addresses.

• A hub and a switch both operate at the data link layer and selectively forward data based on MAC addresses.

• A hub and a switch both operate at the physical layer and broadcast data to all connected devices.

• A hub operates at the data link layer and selectively forwards data based on MAC addresses, while a switch operates at the physical layer and broadcasts data to all connected devices.

What is the main difference between a router and a switch?

• A router operates at the physical layer (Layer 1) and is responsible for forwarding data packets within a network, while a switch operates at the network layer (Layer 3) and is responsible for routing packets between different networks.

• A router operates at the network layer (Layer 3) and is responsible for routing packets between different networks, while a switch operates at the data link layer (Layer 2) and is responsible for forwarding data packets within a network.

• A router and a switch are the same thing and can be used interchangeably.

• A router is used for wired networks, while a switch is used for wireless networks.

What is the main difference between a router and a hub?

• A router can intelligently route data packets based on IP addresses, while a hub simply broadcasts data to all connected devices.

• A router can only connect a limited number of devices, while a hub can connect an unlimited number of devices.

• A router and a hub perform the same function of connecting devices to a network.

• A router and a hub both broadcast data to all connected devices.

What is the main difference between a switch and a hub?

• Switches operate at the physical layer and broadcast all incoming data, while hubs operate at the data link layer and use MAC addresses to forward data.

• Switches operate at the data link layer and use MAC addresses to forward data, while hubs operate at the physical layer and broadcast all incoming data.

• Switches and hubs are the same and can be used interchangeably.

• Switches and hubs both operate at the physical layer and use MAC addresses to forward data.

What is the purpose of wireless access points in a computer network?

• The purpose of wireless access points is to block access to devices in a computer network.

• The purpose of wireless access points is to provide wired connectivity to devices in a computer network.

• The purpose of wireless access points is to provide physical security to devices in a computer network.

• The purpose of wireless access points is to provide wireless connectivity to devices in a computer network.

What are the advantages of using Ethernet cables for network connectivity?

• Ethernet cables are more difficult to set up than wireless connections.

• Ethernet cables are less secure than wireless connections.

• Ethernet cables provide faster and more reliable network connectivity compared to wireless connections.

• Ethernet cables are more expensive than wireless connections.

What are the advantages of using WiFi for network connectivity?

• WiFi offers wireless connectivity and allows multiple devices to connect simultaneously.

• WiFi can only connect one device at a time.

• WiFi is less secure than wired connections.

• WiFi is slower than wired connections.
