Understanding Network Protocols and Layers

What is the primary function of the Network Layer in the OSI model?

• To provide error-free data transfer

• To route packets between different networks

• To establish, manage, and terminate connections

• To encrypt data for secure transmission

Which of the following is a valid IPv4 address?

• 192.168.1.1

• 256.100.50.25

• 123.456.78.90

• 10.0.0.999

What is the main difference between HTTP and HTTPS?

• HTTPS uses a different port number than HTTP

• HTTP is faster than HTTPS

• HTTPS encrypts data for secure transmission

• HTTP is used for email, while HTTPS is used for web browsing

Which protocol is primarily used for sending emails?

What is the main purpose of the Transmission Control Protocol (TCP)?

• To provide a connectionless communication service

• To ensure reliable data transmission

• To encrypt data for secure transmission

• To route packets between different networks

Which of the following is NOT a layer in the 4-layer model?

• Application Layer

• Transport Layer

What is the primary difference between an IP address and a MAC address?

• IP addresses are used for local network communication, while MAC addresses are used for global communication

• IP addresses are unique to each device, while MAC addresses can be shared

• IP addresses can change, while MAC addresses are fixed to the hardware

• IP addresses are used for email, while MAC addresses are used for web browsing

Which protocol is used to retrieve emails from a server?
