TCP Layers

What are the layers of the TCP/IP model?

• A, B, C, D

• Input, Output, Process, Storage

• Red, Blue, Green, Yellow

• Application, Transport, Internet, and Link

Name a protocol used in the application layer.

• HTTP

• TCP

• SMTP

• FTP

What are the functions of the transport layer?

• End-to-end communication, error-checking, and data flow control

• Creating user interfaces

• Managing hardware resources

• Sending and receiving emails

How are devices identified at the network layer?

• Social security numbers

• IP addresses

• MAC addresses

• Phone numbers

Give an example of a data link layer protocol.

• Ethernet

• WiFi

• Bluetooth

• USB

Explain the process of data transmission at the physical layer.

• Analog data is transmitted as is without any conversion

• Data is transmitted through the application layer

• Digital data is converted into signals for transmission over the physical medium, and then received and converted back into digital data at the receiving end.

• Data is transmitted through the network layer

Which layer of the TCP/IP model is responsible for routing?

• Network layer

• Data link layer

• Application layer

• Transport layer

What is the role of the application layer in the TCP/IP model?

• Provides network services to end-user applications

• Manages physical connections between devices

• Handles error checking and data flow control

• Responsible for routing packets across the network

What is the main function of the transport layer?

• Ensuring data security

• Providing physical addressing

• Controlling the flow of data through the network

• Ensuring reliable and accurate data transmission

How does the data link layer ensure error-free transmission?

• Physical layer transmission

• Packet filtering

• Data encryption

• Error detection and correction, retransmission of lost or corrupted data, and flow control
