A packet is a unit of data that is transmitted over a network. It is a basic building block of network communication, and is typically sent and received by devices on a network in order to exchange information.

A packet is typically composed of several different layers of information, each of which serves a specific purpose. For example, the lowest layer of a packet may contain information about the physical hardware that is being used to transmit the packet, while the next layer up may contain information about the network protocol that is being used to send the packet. Higher layers may contain information about the application that is sending the packet, or the data that is being transmitted.

Packets are typically sent using a network protocol, which is a set of rules that govern how devices communicate on a network. Different protocols may be used for different types of network traffic, depending on the requirements of the application or service that is sending the packets.

In summary, packets are the basic units of data that are transmitted over a network, and are composed of multiple layers of information. They are typically sent and received using a network protocol, and are used by devices on a network to exchange information.

Example 

Here is an example of packets being transmitted over a network:

  1. Alice wants to send a message to Bob using a messaging app. She types the message into the app on her phone and clicks “Send”.
  2. The messaging app breaks the message into smaller units of data, called packets. Each packet contains information about the sender (Alice), the recipient (Bob), and the message itself.
  3. The packets are then sent over the network, using a network protocol such as TCP or UDP. The protocol ensures that the packets are sent and received in the correct order, and that any lost or corrupted packets are re-transmitted.
  4. The packets are received by Bob’s phone, which reassembles them into the original message. Bob can then read the message in the messaging app on his phone.

In this example, the packets are the units of data that are transmitted over the network in order to exchange information between Alice and Bob. Each packet contains information about the sender, the recipient, and the message itself, and is sent and received using a network protocol.

He is an Author, Inventor, UAS Engineer, Blogger//Speaker and Entrepreneur. He has completed Aircraft Maintenance Engineering (AME). After the completion of the course, He shifted to Manila Aviation, Philippines to obtain the experience of Bell 407 Helicopter and Super King Air B200 aircraft. Also, accomplished accreditations in Human Factors, Aircraft Systems, Jet Engines, and Airframe, identified with wide-body aircraft, such as A320, A340, and B737. Later on, He joined a privately held UAV Company as a UAV Technical Engineer, where, during the exploration of Unmanned Aerial Vehicles, He transmuted his ‘Manned Aircraft’ knowledge into ‘Unmanned Aircraft’ and designed ‘India’s first Drone crash course study material’. Aside from Technical work, coordinated numerous workshops and training sessions to train the Engineering students regarding the Unmanned Aviation field as well as participated in the HALE/MALE sorts UAVs venture. Presently, He is working as a Director in a private UAV Manufacturing company (VAU Technovations LTD.). His recently formed UAV include VTOL UAV with Virtual Pilot and inventions comprise ‘Blended wing body flapless VTOL UAV, controlling with bleed air motion control system’ and more. As well as he authored a book, which comprises a detailed description related to all elements of the Unmanned Aircraft System. “Since, beginning He was very much interested in to produce something new, which never been done before to change the reality. The way, which drives this sort of deduction falls under the enterprising space, where somebody controls the entire Universal laws to reimage it by his own specific manner to make outlandishly conceivable.” By keeping an innovator mindset, after the completion of the course, He joined India based Start-Up company in the Drone sector. Where he got the undertaking to design ‘UAV Courses’ and the ‘Fledged Unmanned Device’ without any assistance. It becomes very hard to work, out of your prepared space. ‘Reimagination factor’ empowered him to plan ‘Practical UAV Courses’ as well as ‘Fledged Unmanned Device’ identified with numerous applications. During the working session, organized many training sessions and Signed MOUs with different colleges to train the engineering students in his own defined way. After that joined a couple of Start-Up companies (INDIA/South Africa) in a similar area as a Pioneer to deliver them ‘Initial Stage Boosting Strategies’ to cause them to survive in the market with limited resources. Parallelly, continues to contribute his own opportunity to tackle the genuine issues, which addressed by customers. Presently, working on, to be a Global competitor in the DRONE sector by manufacturing a completely indigenous Advanced Unmanned Aircraft System with Uniquely planned calculations. Awarded by many Engineering colleges for his work in DRONE Training Domain. In 2017, ‘Entrepreneur Magazine’ printed about his Business effort in DRONE Sector. In 2018, Nominated for ‘Visakhapatnam Manufacturing Leadership Award’. His invention sheaf comprises, ‘Blended Wing Body Flapless VTOL UAV, controlling with Bleed Air Motion Control System’, to solve out the Endurance related problem with the capability of carrying both Low-speed and High-speed operations at maximum stealth mode. ‘Unmanned Aircraft System for Under Bridge Bearings Inspection’ to solve out the inspection related problem of ‘Under Bridge Bearings’, The problem was addressed by one of the construction company. An extendable robotic arm with a camera is attached with the HUB of the air vehicle, which eases the ‘Bearings’ related inspections inside the ‘confined spaces’. ‘AI DRONE with Virtual Pilot’, Virtual pilot concept makes the controlling and troubleshooting of the air-vehicle easy. The purpose for to concoct the ‘Virtual Pilot’ is to ease the controlling and troubleshooting of the air-vehicle for the Non-Engineer operator. And the invention related to the defense sector comprises, ‘Lightning Strike System’, A MALE/HALE UAV payload system that channelizes the ionized plasma through MV channels to neutralize the targets. Additionally, Related to the Agriculture sector, the commercially launched ‘AGRORECK’ series ‘Pesticide spraying’ and ‘Multi-spectral imaging DRONES’ to solve the AGRO-related problems.
