What are data packets ?
Data packets are units of data that are transmitted over a network.
Data packets are the basic building blocks of network communication and are used by various network protocols to facilitate communication between devices.
Data packets are an essential part of modern networking technology, allowing computers and other devices to communicate with each other across vast distances.
They are used in everything from email and file sharing to video conferencing and online gaming, and they are a critical component of the modern digital world.
Parts of a Data Packet
A data packet consists of two main parts:
The payload and header are separated by a delimiter, which indicates the end of the header and the beginning of the payload.
The delimiter in a data packet can vary depending on the protocol being used, but it is typically a special character or sequence of characters that are recognized by the network devices.
Overall, the header and payload work together to facilitate the transmission of data packets across a network. The header provides the necessary information to manage the packet's transmission, while the payload contains the actual data being transmitted.
When a device sends a data packet over a network, the packet is typically broken up into smaller units called "segments" or "frames". These segments or frames are then transmitted over the network using various protocols such as TCP/IP or Ethernet. When the receiving device receives these segments or frames, it reassembles them into the original data packet.
