Networking and Internet Fundamentals

What are the seven layers of the OSI model?

• 1) Data Link, 2) Network, 3) Transport, 4) Application, 5) Session, 6) Presentation, 7) Internet

• 1) Network, 2) Transport, 3) Internet, 4) Session, 5) Application, 6) Presentation, 7) Data Link

• 1) Physical, 2) Data Link, 3) Network, 4) Transport, 5) Session, 6) Presentation, 7) Application

• 1) Physical, 2) Data Link, 3) Network, 4) Transport, 5) Application, 6) Network Layer, 7) Session

Which layer of the OSI model is responsible for end-to-end communication?

• Data Link layer

• Transport layer

• Network layer

• Application layer

What does TCP stand for in the TCP/IP protocol suite?

• Transmission Connection Protocol

• Transmission Communication Protocol

• Transmission Control Protocol

• Transfer Control Protocol

What is the primary purpose of the Internet Protocol (IP)?

• To encrypt data for secure transmission.

• To route and deliver data packets across networks.

• To store data on remote servers.

• To provide a user interface for web browsing.

What is the difference between IPv4 and IPv6 addressing?

• IPv4 uses 64-bit addresses and is more secure than IPv6.

• IPv4 has 32-bit addresses and a limited address space, while IPv6 has 128-bit addresses and a significantly larger address space.

• IPv4 has a larger address space than IPv6 due to its simpler structure.

• IPv4 and IPv6 both use 32-bit addresses but differ in speed.

What is a subnet mask used for in IP addressing?

• To assign static IP addresses to devices.

• To encrypt data transmitted over the network.

• To identify the network and host portions of an IP address.

• To determine the maximum speed of a network connection.

What are the main types of network topologies?

• Star, Bus, Ring, Mesh, Tree

• Circular

• Hexagonal

• Square

Which topology connects all devices to a single central hub?

• Ring topology

• Bus topology

• Star topology

• Mesh topology

What is the advantage of a mesh network topology?

• Faster data transmission speeds with fewer connections.

• Simplified network management with fewer devices.

• Increased reliability and fault tolerance due to multiple pathways for data transmission.

• Lower installation costs due to minimal cabling.

What wireless standard operates at 2.4 GHz and supports up to 54 Mbps?

• IEEE 802.11g

• IEEE 802.15.4

• IEEE 802.11b

• IEEE 802.11n
