OSI Model, Networks, IP

What is the function of the Physical layer in the OSI model?

• Establish end-to-end connections

• Perform error checking on data

• Translate data into packets

• Transmit raw data bits over a physical medium

What are the three types of networks based on their geographical scope?

• SAN

• LAN, WAN, MAN

• CAN

• PAN

What is a LAN network and what does it stand for?

• Local Area Network

• Laptop Area Network

• Large Area Network

• Local Access Network

Explain the concept of a WAN network.

• A WAN network covers a broad area and connects multiple LANs.

• A WAN network covers a small area and connects a single LAN.

• A WAN network is limited to a specific country.

• A WAN network only operates within a single building.

Differentiate between private IP and public IP.

• Private IP addresses are used within a private network, while public IP addresses are globally unique and can be accessed over the internet.

• Private IP addresses are accessible from any location

• Public IP addresses are only used for internal communication

• Private IP addresses are used for public websites

What is the range of IP addresses for private IPs?

• 150.0.0.0 - 150.255.255.255

• 100.100.100.100 - 100.200.200.200

• 10.0.0.0 - 10.255.255.255, 172.16.0.0 - 172.31.255.255, 192.168.0.0 - 192.168.255.255

• 172.32.0.0 - 172.63.255.255

How are public IP addresses assigned?

• Public IP addresses are assigned by random number generators

• Public IP addresses are assigned by aliens

• Public IP addresses are assigned by ISPs or network administrators through DHCP or manual configuration.

• Public IP addresses are assigned by telepathy

Which OSI layer is responsible for connections?

• Data Link Layer (Layer 2)

• Transport Layer (Layer 4)

• Network Layer (Layer 3)

• Physical Layer (Layer 1)

What is the purpose of the Network layer in the OSI model?

• To provide physical addressing of devices within the same network

• To provide logical addressing, routing, and forwarding of data packets between different networks

• To ensure error-free transmission of data packets

• To manage user authentication and authorization

What is the significance of the Transport layer in the OSI model?

• Responsible for displaying data on the screen

• Handles encryption and decryption of data

• Manages physical connections between devices

• Ensures end-to-end communication, data reliability, error-checking, and flow control.
