Exploring Computer Networks

What is the purpose of network protocols?

• To establish a physical connection between devices.

• To manage power consumption in devices.

• To encrypt data for secure transmission.

• The purpose of network protocols is to enable communication and data exchange between devices in a network.

Name three common network protocols.

• TCP, UDP, HTTP

• POP3

• SMTP

• FTP

What is an IP address?

• An IP address is a unique numerical label assigned to each device on a network.

• A type of software used to manage networks.

• A protocol for sending emails.

• A physical device that connects to the internet.

Explain the difference between IPv4 and IPv6.

• IPv4 uses 64-bit addresses; IPv6 uses 32-bit addresses.

• IPv4 is a 32-bit address scheme with about 4.3 billion addresses; IPv6 is a 128-bit scheme with a vastly larger address space.

• IPv4 has unlimited addresses; IPv6 has a limited address space.

• IPv4 is primarily used for mobile devices; IPv6 is used for desktop computers.

What is a subnet mask?

• A subnet mask is used to encrypt data.

• A subnet mask is a type of firewall.

• A subnet mask is used to define the network and host portions of an IP address.

• A subnet mask is a physical device that connects networks.

What is the purpose of DHCP in IP addressing?

• The purpose of DHCP in IP addressing is to automatically assign IP addresses and other network configuration settings to devices on a network.

• To provide a static IP address for each device.

• To encrypt network traffic between devices.

• To manually assign IP addresses to devices.

What are the main components of a wireless network?

• Desktop computers only

• Modem and Ethernet cables

• Wireless access point, wireless network adapters, router, repeaters/extenders, security protocols.

• Fiber optic cables and switches

What is the difference between Wi-Fi and Ethernet?

• Ethernet requires a router; Wi-Fi does not.

• Wi-Fi is used for gaming; Ethernet is for browsing.

• Wi-Fi is wireless; Ethernet is wired.

• Wi-Fi is faster than Ethernet.

What is the role of a router in a network?

• A router amplifies signals to extend network range.

• A router stores data packets for later use.

• A router directs data packets between networks and connects multiple devices.

• A router is used solely for wireless connections.

Explain the function of a switch in networking.

• A switch is used to connect to the internet directly.

• A switch amplifies signals in a network.

• A switch stores data permanently for backup purposes.

• A switch connects devices in a network and forwards data based on MAC addresses.
