What is a network topology?

• The speed at which data is transferred in a network

• The process of connecting computers to the internet

• The layout or structure of a computer network

• The type of cables used in a network

Name two types of network topologies.

• tree topology

• mesh topology

• star topology, ring topology

• bus topology

What is a network protocol?

• A network protocol is a programming language used to write network applications.

• A network protocol is a set of rules and conventions that govern the communication between devices in a network.

• A network protocol is a physical device used to connect computers.

• A network protocol is a type of computer virus.

Give an example of a network protocol.

• Internet Protocol (IP)

• User Datagram Protocol (UDP)

• Hypertext Transfer Protocol (HTTP)

• Transmission Control Protocol (TCP)

What is IP addressing?

• IP addressing is a method used to assign random numerical addresses to devices connected to a computer network.

• IP addressing is a method used to assign alphabetical addresses to devices connected to a computer network.

• IP addressing is a method used to assign unique numerical addresses to devices connected to a computer network.

• IP addressing is a method used to assign the same numerical addresses to all devices connected to a computer network.

What is the purpose of IP addressing?

• To slow down network communication.

• To encrypt data on a network.

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

• To prevent devices from connecting to a network.

What is an IP address?

• A password used to access a computer network.

• A type of computer virus.

• A software program that controls internet access.

• A unique numerical label assigned to each device connected to a computer network.

What is the format of an IPv4 address?

• The format of an IPv4 address is a single number.

• The format of an IPv4 address is three sets of numbers separated by commas.

• The format of an IPv4 address is a combination of letters and numbers.

• The format of an IPv4 address is four sets of numbers separated by periods.

What is the difference between IPv4 and IPv6?

• IPv4 uses decimal addresses while IPv6 uses hexadecimal addresses.

• IPv4 uses 32-bit addresses while IPv6 uses 128-bit addresses.

• IPv4 uses 16-bit addresses while IPv6 uses 32-bit addresses.

• IPv4 uses 64-bit addresses while IPv6 uses 128-bit addresses.

What is a subnet mask?

• A subnet mask is a security feature used to protect a network from unauthorized access.

• A subnet mask is a type of computer virus that can infect a network.

• A subnet mask is a 32-bit number used to divide an IP address into network and host addresses.

• A subnet mask is a hardware device used to connect multiple computers to a network.
