What is the difference between a hub and a switch?

• A hub and a switch are the same thing.

• A hub is a basic networking device that broadcasts data to all connected devices, while a switch is a more advanced device that creates direct connections between devices for faster and more efficient data transmission.

• A hub is more advanced than a switch.

• A switch broadcasts data to all connected devices.

What is the function of an IP address?

• To control the speed of internet connection on a device.

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

• To determine the physical location of a device on a network.

• To encrypt data transmitted between devices.

What is the difference between TCP and UDP?

• TCP and UDP are both connectionless protocols that do not guarantee reliable delivery.

• TCP is a connectionless protocol that does not guarantee reliable delivery, while UDP is a connection-oriented protocol that ensures reliable and ordered delivery of data.

• TCP is a connection-oriented protocol that ensures reliable and ordered delivery of data, while UDP is a connectionless protocol that does not guarantee reliable delivery.

• TCP and UDP are both connection-oriented protocols that ensure reliable and ordered delivery of data.

What is a subnet mask used for?

• A subnet mask is used to encrypt data transmitted over a network.

• A subnet mask is used to identify the physical location of a device on a network.

• A subnet mask is used to divide an IP address into two parts, the network address and the host address.

• A subnet mask is used to determine the speed of a network connection.

What is the purpose of a firewall in network security?

• The purpose of a firewall is to protect the computer from viruses

• The purpose of a firewall is to allow all traffic to pass through

• The purpose of a firewall in network security is to establish a barrier between a secure internal network and an external network or the internet, in order to prevent unauthorized access to or from the internal network.

• The purpose of a firewall is to slow down the network speed

What is the role of DNS in a network?

• DNS translates domain names into IP addresses.

• DNS provides internet connectivity.

What is the purpose of NAT in networking?

• NAT is used to encrypt network traffic

• NAT is used to increase network speed

• NAT is used to translate private IP addresses to public IP addresses and vice versa.

• NAT is used to block incoming network traffic

What is the OSI model and how does it relate to networking?

• The OSI model is a software program used for networking.

• The OSI model is a physical device used for networking.

• The OSI model is a protocol used for networking.

• The OSI model is a conceptual framework that standardizes the functions of a communication system into seven different layers.
