Digital mode used by amateur radio operators. The US Coast Guard, the Hancock International Airport and some other agencies outside the region use packet as well. Data packets are assembled by a device called a Terminal Node Controller (TNC) which adds control, routing and error detection information to each data frame. When the receiving station successfully decodes a packet, it sends an ACKnowledgement back to the sender. Otherwise, it sends a NAK which prompts the sender to retry the bad packet. Packets can be relayed over great distances using digipeaters. A digipeater ( hams call it "digi" for short) can either retransmit packets on the same frequency where they were received or redirect them to another channel. Amateur operators have set up networks of packet stations that automatically forward messages on VHF and UHF bands, on shortwave and via satellite. Hams can read messages and transfer files on packet bulletin boards and on orbiting store-and-forward mailboxes. (see OSCAR)

Protocol - The rules of the network "game".Twisted Pair -Twisted pair is the ordinary copper wire that connects home and many business computers to the telephone company. To reduce crosstalk or electromagnetic induction between pairs of wires, two insulated copper wires are twisted around each other. Each connection on twisted pair requires both wires. Since some telephone sets or desktop locations require multiple connections, twisted pair is sometimes installed in two or more pairs, all within a single cable. For some business locations, twisted pair is enclosed in a shield that functions as a ground. This is known as shielded twisted pair (STP). Ordinary wire to the home is unshielded twisted pair (UTP).

Each of these packets is separately numbered and includes the IP address of source and the destination. The individual packets for a given file may travel different routes through the network to the destination. When they have all arrived, they are reassembled into the original file (by TCP/IP at the receiving end).
A collection of bits that constitutes one network transmission. Packets must include relevant network address and accounting information, as well as user data.

It has an eclectic heritage, deriving from the ubiquitous C programming language and to a lesser extent from sed, awk, various Unix shell languages, Lisp, and at least a dozen other tools and languages. Originally developed for Unix, it is now available for many platforms. It is particularly popular for writing CGI scripts.
In data communication, the basic logical unit of information transfer.
sometimes called datagram, a packaged unit of characters or other form of computer output sent from one computer to another over a network.

Refers to the data-unit of the Network-Layer (layer-3). A packet usually includes a logical address to be used by routing devices. Messages are segmented and segments placed in packets with a logical address header. Packetising data allows greater throughput through noisy or congested communications environments. Sending a 1,000,000 bit message through an environment with a 1-in-10^6 error rate will result in zero throughput. Transmitting 10 packets of 100,000 bit will result in a 90% throughput.
A block of data sent over a network which includes the addresses of the sending and receiving computers, the actual information, and error control.
The smallest unit of data passed through the Internet. Every file transmitted across the Internet, no matter how large is broken down into equal sized packets. Each packet has the address of its destination plus, the details of where it fits into the jigsaw puzzle of its larger, original file. As each packet passes through the Internet, each server will read the address contained in the packet header so it is forwarded to the correct destination. On arrival at the destination, the receiving computer will wait for all the packets that make up a file to arrive before it looks at the information contained within the packets to rebuild the original file.
A small unit of information transferred across a network file transfer or web page download may involve several packets.
A unit of data exchange between hosts.

This is a unit of data, which is typically a part of a file, that has been prepared for transmission across a network, usually the internet.
Integral number of sectors forming a single unit of information that can be incrementally written or overwritten.
When data is transmitted over the network it is broken up into smaller pieces called packets and individually routed to their destination. This way if one packet is not properly received, the receiving party can request resubmission of the single packet, as opposed to the entire piece of data. Each packet contains headers, which are responsible for the successful transmission of the packet, and a data part, which contains a portion of the original data being transmitted over the network. The term packet is used when referring to layer 3 devices (i.e. a router). A frame is the term used when referring to layer two devices (i.e. a switch).
A collection of bits, including the address, data and control, that are switched and transmitted together. The terms frame and packet are often used synonymously.

A block of information sent over a network. A packet typically contains a source and destination network address, some protocol and length information, a block of data, and a checksum.
In file transfer protocols, a packet is the amount of data which is transmitted in one lump, before each computer checks to ensure that the packet has been transmitted correctly. This saves time in transmitting files, since the whole file does not need to be re-sent if only one part of it gets corrupted during transmission. Only the corrupted packet needs to be re-sent. 2. In FidoNet mail transfers or offline mail readers on a BBS, all the new mail for a BBS or a user is compressed into one file called a packet.
A single unit of network traffic.

Units of information sent from one computer to another over a network. When transferring a file over a network, the file is broken down into multiple, numbered packets. To preserve bandwidth, packets have a set maximum size that is usually smaller than the actual file(s) requested. Network congestion sometimes requires that packets be dropped in transit, then re-requested by the recipient before being rebuilt into the originally requested file.
A packet is a basic communication data unit used when transmitting information from one computer to another. The maximum length of a packet depends on the communication medium. As an example, in Ethernet networks the maximum length is1500 bytes. A data packet can be divided into two parts: the header part and the data part. The header contains information needed for communication between nodes; the data is the body of the packet that is ultimately received by the application.
switching The method by which most data is exchanged throughout the Internet. Most data is broken down in to smaller "packets" prior to transfer, and then reassembled at the destination.
A block of data with a "header" attached that can indicate what the packet contains and where it is headed. Think of a packet as a "data envelope," with the header acting as an address.
Data is grouped in packets for transmission over the circuit by the Data Link protocol. The packet includes data, and any other information needed to get the data to it's proper destination. Depending on the protocol used, this may include error correction, source address, destination address, etc.
Generic term for a bundle of data, usually in binary form, organized in a specific way for transmission.
An ordered group of data and control signals transmitted through a network as a subset of a larger message.
A piece of data transmitted over a packet-switching network such as the Internet. A packet includes not just data but also its destination.
A piece of data transmitted over a packet-based network, such as a TCP/IP network. Also called datagram. All data transmitted over the Internet, for example, is transmitted via packets. Since each packet can take a different route to its destination, traffic loads on each individual route are reduced, thus improving network efficiency. When all packets arrive at the destination, the original message can be reassembled. In the event that a packet does not reach its destination, the packet is resent along a different route. The term packet loss refers to how many packets (usually expressed as a percentage of the total number of packets) never made it to the final destination. Ideally, packet loss should be close to zero.
A small unit of digital data that is transferred within or between networks. On the Internet, packets are created by use of the Transmission Control Protocol (TCP) and sent from one location to another via Internet Protocol (IP).

Network protocols divide files into packets, or smaller, more manageable chunks of data for transmission through the TCP layer of TCP/IP. Not all the components of a single packet, sent in this way, may use the same route to a destination, since route conditions may change very quickly, and a router may switch packets to travel by alternate routes as it deems best.
Data sent over a LAN is separated into blocks known as packets to create optimum transfer over a packet-switching network. One of the key features of a packet is that it contains the destination address in addition to the data. See Packet-switching.
is a generic term for a bundle of data organized in a specific way for transmission. Data are broken up into packets for sending over a packet switching network. Each packet has a header containing its source and destination, a block of data content and an error-checking code. All the data packets related to a message may not take the same route to get to their destination; they are reassembled once they have arrived.
A unit of data which is small enough that it can be transmitted efficiently over a packet-switched network. Packets contain data and the destination address.
A block of data that can be transmitted from one computer to another on a network like the Internet. A packet contains data to be transmitted, data to guide the packet, and data that corrects error along the way. A transmission's packets are split up before sending and reassembled at the destination.
A unit of digital data with a set number of bits, including some bits that serve as an address code. The packet can be sent through a packet switching network by the best route, and reunited at its destination with the other message packets, regardless of the route each took, or the order of their arrival.
A packet can be described as a logical grouping of information including header and (generally) user data. Packets are commonly used to refer to network layer units of data and can also often be termed datagrams, frames, messages and PDUs (Protocol Data Unit) to name but a few.
A means of breaking a network communication down into smaller units so that they can be more efficiently routed from the source computer to the destination computer over the network. When they reach the destination computer, the packets are then reassembled to form the original transmission.
A packet is a self-contained bundle of data sent over a packet switching network. Packets are typically less than 1500 bytes in size. Longer files are broken into multiple packets for transmission and reassembled at the other end. A packet includes a header with to and from addresses, relation to other packets (sequencing), and error checking information. On the Internet, datagram is a synonym for packet. See TCP/IP.
A bundle of data organized in a specific way of transmission. The three principal elements of a packet include the header, the text, and the trailer (error detection and correction bits).
A block of data in a standard format for transmission.
When a file is sent over the Internet, it is disassembled into data packets. Each packet contains the target address and information on how to reassemble. This means that data packets can take different routes across the Internet. When at their destination the packets, regroup to assemble the original file.
A unit of data that is sent across a network
A chunk of data. The TCP/IP protocol breaks large data files into smaller "packets" for transmission. When the data reaches its destination, the protocol makes sure that all packets have arrived without error.
A packet is a message fragment containing data or information. When messages are sent on the Internet, they are broken into smaller, more easily transportable pieces called packets. Each packet consists of a header and a piece of the message. A single e-mail message may actually be broken into a half-dozen different packets.
The smallest unit for transmitting data over the Internet. Data is broken up into packets, sent over the network and then reassembled at the other end.
In data communication, the basic unit of information transferred.
A collection of data that contains, among other things, the address of the computer that should respond to it. A typical computer transmission can consist of hundreds or even thousands of packets. When a computer sends information across a network, it divides that information into packets. These packets are re-assembled into the original transmission by the computer that receives them.
a group of binary digits switched as a whole - for instance, a file transfer over a packet switched network would require many steps. These steps are: 1) the data file would be broken down into smaller "packets" of information 2) each packet of information is assigned a code that enables it to be sent to the correct location and, once at that location, for the network to reassemble the packets of information into their original form.
a discrete block of data sent over a network
A basic message unit for communication across a network. A packet usually includes routing information, data, and sometimes error detection information.
to send a message over a packet-switched network, the whole message is first cut up into smaller "packets" and each is numbered and labeled with an address saying where it came from and another saying where its going.
The fundamental unit of communication on the Internet.
A group of related items. A packet may refer to the arguments of a subroutine or to a group of bytes that is transmitted over a network.
A collection of network data sent at once from one network node to another.
A single fragment of data on an IP computer network. Machines can communicate on a network by exchanging series of packets.
A unit of data sent across a network. When any data is sent across the Internet, it is broken into sections of data, and each section (the packet) is sent until all the sections arrive at their destination where they are reassembled to the form meant for the recipient.
The data transfer unit used in network and modem communications. Each packet contains data and a header which contains information as to the sending machine and the receiving machine, as well as the necessary information for the receiving machine to reassemble the data at its end. See also Network and Modem.
A burst or chunk of data that is sent over a network, whether it's the Internet or wireless network.
A logical group of data. A packet includes a header, which contains addressing and other control information, and the payload (user data). Data travelling through any network is broken up into packets.
A packet is a small block of transmitted data. Several packets are used in a typical transmission.
A collection of data that is transmitted as a bundle across a network connection.
A block of information configured for transmission over a network.
A small part of a message (i.e., email or streaming media clip) containing data and a destination address that is sent over a network. Parceling messages into smaller pieces and sending them one packet at a time puts a far lighter load on network resources than sending an entire file all at once.
A piece of data that has a series of headers and footers attached to tell the appropriate devices such information as its source, destination, and what kind of information is being carried. Networking
A fixed number of bytes that represents the basic unit of information sent across a physical network. Packets consist of binary information representing both data and a header containing an ID number, source and destination addresses, and error-control data.
In TCP/IP, a term referring to the data passing between the Internet layer and the data link layer. Also a generic term used to refer to data transferred through a network.
Data on the internet is transmitted in baskets of information called baskets ofÂ information which includes where the data came from, where the data is being sent, what type of data is being transferred, and the data itself.
A unit of data that is routed between a source and a destination on a network.
A group of binary digits including data and control elements which is switched and transmitted as a composite whole. The data and control elements, and possibly error control information, are arranged in a specified format. (3)
A unit of data. Each message sent between two network devices is often subdivided into packets by the underlying hardware and software. Depending on the protocol the packets have their own formats.
A small amount of computer data sent over a network. Any time you receive data from the Internet, it comes to your computer in the form of packets.
A logically grouped unit of data. Packets contain a â€œpayloadâ€ (the information to be transmitted), originator, destination, and synchronization information. The idea with packets is to transmit them over a network so each individual packet can be sent along the most optimal route to its destination. Packets are de-constructed on one end of the communication and re-constructed on the receiving end based on the header addressing information at the front of each packet. Routers in the network will store and forward packets based on network delays, errors, and re-transmittal requests from the receiving end.
A unit of data transmitted over a data network. TCP/IP is a data packet network.
A unit of information that can be sent from one computer to another. A packet contains user data or protocol information or both. Also called a "datagram."
A block of data sent over the network transmitting the identities of the sending and receiving stations, error-control information, and message.
A sequence of binary digits that is transmitted as a unit in a computer network. A packet usually contains control information plus data.
A unit of data sent over a network.
Computers send and receive information across networks in packets. As a rough rule of thumb, the higher the level of detail that a game has, the more packets it will have to ship across the network in order to allow a player to participate in an on-line game. The more packet hungry a game is, the more issues of bandwidth become crucial for high pingers.
A packet is a unit of data encapsulated by a physical network protocol header and/or trailer. In general, the header provides control and routing information for directing the packet through the fabric, while the trailer contains data for ensuring packets are not delivered with corrupted contents. Other "packetized" transport mechanisms include IP, the Internet Protocol, and the new VXA tape format.
A chunk of information sent over a network. Each packet contains the address it is going to, the address of who sent it, and some other information.
Fundamental unit of data handled by networks. When large files are sent over a network, they are first broken down into several smaller packets. The packets are then re-assembled at the remote end. Back
a bundle of data transmitted over a network, including information about where the data came from where it's headed, and other overhead baggage like error-detection aids.
Also known as a "frame," each packet contains addressing and control information. Packets are variable length, up to a maximum size. Packets for different technologies usually have a minimum and maximum size allowed. For example, Ethernet has a minimum of 64 bytes and a maximum length of 1,500 Bytes. The variable length of frames also means variable delays when traversing a network device.
A block of data used for transmission in packet-switched systems.
The smallest unit of data in the TCP/IP protocol. That contains data payload and header information used to route the data and reassemble a complete data stream from many individual packets. Close Window
A packet is a chunk of information sent over a network. Packet-switching is the process by which a carrier breaks up data into these chunks or packets. Each packet contains the address of origin, the address of its destination, and information about how to reunite with other related packets. This process allows packets from many different locations to co-mingle on the same lines and be sorted and directed to different routes by special machines along the way
A specific number of bits of data sent over a link in a packet switched network. A packet contains the data and control information needed for the successful delivery of the packet to the desired address. The terms packet and frame are often used interchangeably.
A piece of a message transmitted over a computer network. Contains not only the message which you are sending but also its destination address.
In a packet-switched network such as the Internet, data is packaged and routed in 'blocks' or packets, each having a header with the network destination address. Packet-switched networks are also described as 'connectionless', because the paths selected by routers can vary from moment to moment as each router is updated with current network information.
From Glossary of "Weaving the Web" ( 1999-07-23) A unit into which information is divided for transmission across the Internet.
A piece of a message transmitted over a packet-switching network. A packet contains not only data but also its destination address on the network.
Information moves around the Internet in 'packets'; chunks of data each with their own destination address. Think of packets as sealed envelopes containing data, with addresses written on them. They all go through the system, and usually end up at the correct destination. The more envelopes the system must handle, the slower the process becomes.
Before any data is sent across a network it is broken down into smaller pieces - known as packets. Each packet is transmitted individually and then reassembled by the recipient computer back into its original form.
A unit of data sent across a network. Information sent over the Internet (and many other networks) in packets is split up into pieces and reassembled when it reaches its destination.
Logical grouping of information that includes a header containing control information and (usually) user data. Packets are most often used to refer to network layer units of data. The terms datagram, frame, message, and segment are also used to describe logical information groupings at various layers of the OSI reference model and in various technology circles. See also PDU.
The unit of data that is routed between an origin and a destination on the Internet or any other packet-switched network. When any file (e-mail message, HTML file, etc.) is sent from one place to another, it is divided into individual packets that may travel different routes through the Internet or network and then are reassembled into the original file at the receiving end.
Continuous sequence of binary digits of information is switched through the network and an integral unit. Consists of up to 1024 bits (128 octets) of customer data plus additional transmission and error control information.
A unit of data sent across a network. Packet is a generic term used to describe a unit of data at any layer of the OSI protocol stack, but it is most correctly used to describe application layer data units (application protocol data units, APDUs).
A way of organizing data for transmission to break larger data streams up into smaller bundles that are pieced back together by the recipient based on header, text, and trailer information in each packet. Packet based networks are typically â€œalways onâ€ and do not require the user to initiate a dial-in to connect to the server.
A chunk of data organized in a block for transmission over an IP network. Usually contains header information with origin and source address, and uses error-correction technology to limit the loss of packets. With real-time delivery, the amount of error-correction is low and packets can be lost if there is network congestion.
A packet is a bundle of data that is transferred across a network. A packet contains information to show where it has come from and its destination.
Generic term for a bundle of data, organized in a specific way for transmission. A packet consists of the data to be transmitted and certain control information, including the destination address.
Unit of data that is routed between an origin and a destination on the Internet or any other packet-switched network. Each packet is separately numbered and includes the Internet address of the destination. The individual packets for a given file may travel different routes through the Internet. When they have all arrived, they are reassembled into the original file.
A group of information that is transmitted as a unit over communications lines. Contains a header plus payload.
When you retrieve a document via a network, the document is sent in "packets" which fit in between other messages on the telecommunications lines, and then are reassembled when they arrive at your end. This occurs using TCP/IP protocol. The packets may be sent via different paths on the networks which carry the Internet. If any of these packets gets delayed, your document cannot be reassembled and displayed. This is called a "packet jam." You can often resolve packet jams by pressing STOP then RELOAD. RELOAD requests a fresh copy of the document.
A packet is the unit of data that is routed between an origin and a destination on the Internet or any other packet-switched network. When any file (e-mail message, HTML file, Graphics Interchange Format file, Uniform Resource Locator request, and so forth) is sent from one place to another on the Internet, the Transmission Control Protocol (TCP) layer of TCP/IP divides the file into "chunks" of an efficient size for routing. Each of these packets is separately numbered and includes the Internet address of the destination.
A bundle of data transmitted across a network. It contains the source address (where the packet has come from) the destination address (where it's going to) a packet identifier (what sort of packet it is) and the data being sent.
A digital â€œpackageâ€ of data that allows for more efficient use of radio spectrum and routing over a network, such as the Internet or wireless networks. Each packet is assigned a unique number for routing as well as the Internet address which identifies the packetâ€(tm)s destination. Packets differ in size and in the amount of bits/bytes that they hold.
The "data" unit carried on a link layer. A packet, on an IP network, consists of an entire IP datagram or a fragment of a datagram.
A contiguous sequence of bits or bytes comprising all or part of a message communicated on a network.
A single block of data, packaged and passed over a network. For example, small amounts of data from one computer are placed in a packet, addressed to another computer, and sent to that computer over a network.
An `envelopeÂ¿ or block of data sent over a network; each packet contains addressing information as well as the data being sent.
The elementary unit of data transferred on the Internet or any packet-switched network.
A chunk of data that is sent over a network, whether it's the Internet or wireless network. Packet data is the basis for packet-switched networks, which are under development in the United States as a faster, more reliable method of transferring wireless data than a circuit-switched network. Packet-switched networks eliminate the need to dial in to send or receive information because they are "always on," transferring data without the need to dial. The packets that hold data depend on the size of the data involved; "chunks" are broken down into an efficient size for routing. Each of these packets has a separate number and carries the Internet address for which it is destined.
Data is transmitted over a network in groups or bursts called Packets. Same as single sentance or phrase in a conversation. A packet will have a header that indicates where it is from and where it is going. This header is used along the way for routing and is used by other computers to identify packets addressed to them.
A self-contained block of information containing control and user information that is transmitted across a network
The unit of data transmission on the Internet. A packet consists of the data being transferred with additional overhead information, such as the transmitting and receiving addresses.
A piece of data transmitted over a packet-switching network. One of the key features of a packet is that it contains the network address of where the data is to be sent.

A chunk of data sent across a network; in packet switching the data being transmitted from one computer to another is broken into packets; each packet has the addresses of its origin and where it is going. These chunks mingle in the same lines and are directed and sorted along the way. This system allows more than one person on a line at the same time.
The block of control information and data for one transaction between a host and its network. Packets are the exchange medium used by processes to send and receive data through Internet networks. A packet is sent from a source to a destination.
Strings of bits that contain information and a network address that are routed over different paths on the Internet according to a specific communications protocol.
A small "chunk" of electronic information which is traveling over a computer network (such as the Internet). Documents shared across the Internet are first broken up into packets before sending them to increase the reliability of communication. When Matt used FTP to download a graphics file, he noticed that when the transfer was completed his screen showed that "3562 packets had been successfully received." He wasn't sure what packet meant, but he liked the word "successful" in describing the results of the download
A unit of transmission in data communications. The TCP/IP protocol breaks large data files into smaller chunks for sending over a network so that less data will have to be re-transmitted if errors occur.

A low-level unit of DVD-Video (MPEG) data storage containing contiguous bytes of data belonging to a single elementary stream such as video, audio, control, and so forth. Packets are grouped into packs.
A unit of transmission over a network. The data to be transmitted is split into packets, which are sent individually over the network.
A unit of information formatted according to specific protocols that allow precise transmittal of data from one node in a network to another. Also called a datagram or a data packet, it contains two parts: a header and a payload. The header is like an envelope; the payload is the contents. In Internet Protocol, any message that is larger than 1,500 bytes gets fragmented into packets for transmission.

The unit of data sent across a network.
A group of bits, including data and control signals, arranged in a specific format and transmitted as a whole. The structure of a packet depends on the protocol. In general, a packet includes three principal elements: control information (such as destination, origin, length of packet), data to be transmitted, and error detection and correction bits. An information block identified by a label at layer 3 of the OSI reference model.
A sequenced of digitized information that is sent and switched as a unit. Computer data is sent via packets. The traffic on the network is divided into small pieces called packets that are multiplexed onto high capacity inter machine connections. A packet, which usually contains only a few hundred bytes of data, carries identification that enables computers on the network to know whether it is destined for them or how to send it on to its correct destination.
A fixed block of data transmission which also contains identity and routing information.
A small package of data. TCP/IP breaks messages up into packets, and sends each packet independently to the message destination. The protocol ensures that there is no error in transmission and that the entire message arrives.
A networking transmission unit of fixed maximum size that consists of binary information representing both data, addressing information and error-correction information, created by the data-link layer.
A block of data sent over a network containing the identities of the sender and receiver and content.
