Data packets are units of information collected into one set for transmission through the Internet. Any bit of data that needs to be sent from one system to another must first be broken into smaller pieces to ease communication. Upon reaching the endpoint, these pieces get reassembled to become readable.
Data packets are used in Internet Protocol (IP)-based systems that communicate with one another over the Web. A data packet is also called a “block,” a “datagram,” or a “frame,” depending on the protocol used for its transmission.
To better understand what a data packet is, think of an image that you would like to send to a friend via iMessage. The image would be divided into small pieces before it gets sent, which happens in the background, of course. Your friend sees only the reassembled image afterward.

One of the notable qualities of data packets is that the process of breaking them down and reassembling them happens within mere seconds.
Things Everyone Needs to Know Concerning Data Packets
Data packet transmission involves several elements that include the following:
Bandwidth refers to the size of the Internet pipeline available to a user. It dictates how much information that user can transmit at one time. For data packets, bandwidth refers to how many packets a user can fit in his/her available pipeline. In essence, the bigger the bandwidth, the more data packets it can fit, and the more efficient would the transmission is.
2. Network Congestion
As the number of data packets passing through an Internet pipeline increases, the slower the transmission becomes. The slowdown could result from a small bandwidth or an artificial congestion on the part of an Internet service provider (ISP). A network congestion is comparable to a traffic jam that occurs when a considerable number of cars travel through a small road.
3. Packet Loss
Packet loss occurs when data gets lost during transmission. It can result from network congestion. Often, the effects are most notable for users of online gaming or voice over IP (VoIP) application usage. In such cases, a user’s gameplay or quality of online conversations suffers.
Jitters are irregular data packet transmissions over a network. When an irregularity in transmitting information occurs, confusion on both ends of the network happens. Network congestion and, eventually, packet loss can result from the presence of too much jitter.
5. Web Browser
A web browser is responsible for receiving packets and assembling them into web pages that visitors see. Ideally, a browser can process as much as eight data packets at one time. Available bandwidth affects how fast a page loads. In general, the more data packets a system can process, the faster the page loading time.
Given all these, it is easy to see why data packets are crucial for the proper transmission of information over the Internet—the more effective their transmission, the better the user experience.
