A mobile data pack refers to an add-on which can enable you to boost the amount of data which you can use on your mobile phone. The rate at which you use your data can also be monitored, so you know how much data you have left. Mobile data is a service which provides a similar service to Wi-Fi and allows you to connect to the Internet.
A packet-switched network transmits data that is divided into units called packets.A packet comprises a header (which describes the packet) and a payload (the data). The Internet is a packet-switched network, and most of the protocols in this list are designed for its protocol stack, the IP protocol suite.
The packet is sent from a randomly allocated ephemeral port, and all future packets to host S should be directed to this port. The source host sends numbered DATA packets to the destination host, all but the last containing a full-sized block of data (512 bytes default). The destination host replies with numbered ACK packets for all DATA packets.
The DTLS protocol datagram preserves the semantics of the underlying transport—the application does not suffer from the delays associated with stream protocols, but because it uses User Datagram Protocol (UDP) or Stream Control Transmission Protocol (SCTP), the application has to deal with packet reordering, loss of datagram and data larger ...
In these particular applications, loss of packets is not usually a fatal problem. In VoIP, for example, latency and jitter are the primary concerns. The use of TCP would cause jitter if any packets were lost as TCP does not provide subsequent data to the application while it is requesting a re-send of the missing data.
A Minecraft server is a player-owned or business-owned multiplayer game server for the 2011 Mojang Studios video game Minecraft. In this context, the term "server" often refers to a network of connected servers, rather than a single machine. [ 1 ]

This additional data includes a sequence number that is used to detect packets that are lost or arrive out of order, and a checksum that allows the errors within packet data to be detected. When either problem occurs, TCP uses automatic repeat request (ARQ) to ask the sender to re-send the lost or damaged packet.
