IT 223- Formative Assessment # 1

It is the connecting computers to share information and resources.

Explain the concept of IP addressing and its importance in networking.

• IP addressing is only important for security purposes

• IP addressing is important for identifying and locating devices on a network.

• IP addressing is only used for naming devices on a network

• IP addressing is not necessary for networking

What is the purpose of a router in a computer network?

• To play music in the computer network

• To cook food for the computer

• To forward data packets between computer networks

• To water the plants in the computer network

What is the difference between TCP and UDP protocols?

• TCP is a connection-oriented protocol that provides reliable and ordered delivery of data, while UDP is a connectionless protocol that provides faster but less reliable delivery of data.

• TCP is a connectionless protocol that provides faster delivery of data, while UDP is a connection-oriented protocol that provides reliable and ordered delivery of data.

• TCP and UDP are both connectionless protocols.

• TCP and UDP are the same and can be used interchangeably.

Describe the function of a firewall in computer networking.

• It acts as a barrier between a trusted internal network and untrusted external network, such as the internet.

• It is used to store data on the network

• It is responsible for managing network cables

• It helps in creating virtual private networks

What is a subnet mask and how is it used in networking?

• A subnet mask is a password used to access secure networks in networking.

• A subnet mask is a tool used to hide the identity of a computer on a network.

• A subnet mask is a 32-bit number that separates the network portion and the host portion of an IP address. It is used in networking to determine which part of an IP address is the network and which part is the host.

• A subnet mask is a type of facial mask used to protect the skin from harmful UV rays in networking.

Explain the concept of DNS (Domain Name System) and its role in networking.

• DNS stands for Digital Network Service and is used for online gaming

• DNS is a type of hardware used to connect devices to the internet

• DNS translates domain names to IP addresses and facilitates communication between devices on the internet.

• DNS is a type of computer virus that infects network systems

What are the different types of network topologies? Provide examples for each.

• Bus, Ring, Star, Mesh, Hybrid

• Pentagon

• Triangle

• Square

What is the difference between a hub and a switch in a network?

• A switch broadcasts data to all devices

• A hub and a switch perform the same function in a network

• A hub forwards data only to the intended recipient

• A hub broadcasts data to all devices, while a switch forwards data only to the intended recipient.

Explain the process of data transmission in a computer network.

• Data transmission involves sending data from one device to another through carrier pigeons.

• Data transmission involves sending data from one device to another through a medium such as cables or wireless signals.

• Data transmission is the process of physically transporting data by hand from one device to another.

• Data transmission is the process of converting data into sound waves and transmitting it through the air.
