Packets and Frames

Front

Packets and frames are small pieces of data that form larger messages.

Back

Packets and frames are different in the OSI model. A frame is at layer 2, the data link layer, and does not contain IP addresses.

Front

Encapsulation in networking

Back

Encapsulation involves wrapping data with protocol information at each layer of the OSI model. It is used to handle IP addresses and packets.

Front

Efficiency of packets in data communication

Back

Packets allow efficient data communication across networks by reducing bottlenecks compared to sending large messages.

Front

Reconstruction of images from packets

Back

Images are sent as small packets and reconstructed on the receiving computer to form the final image.

Front

Importance of standardization in networking

Back

Standardization ensures that packets are handled correctly across billions of devices, preventing breakdowns in communication.

Front

Role of headers in Internet Protocol packets

Back

Headers contain additional information for data being sent across a network, ensuring proper handling and delivery.

Front

Time to Live

Back

This field sets an expiry timer for the packet to not clog up your network if it never manages to reach a host or escape.

Front

Checksum

Back

This field provides integrity checking for protocols such as TCP/IP. If any data is changed, this value will be different from what was expected and therefore corrupt.

Front

Source Address

Back

The IP address of the device that the packet is being sent from so that data knows where to return to.

Front

Destination Address

Back

The device's IP address the packet is being sent to so that data knows where to travel next.
