!!! Overview
[{$pagename}] (or [Datagram]) which is part of a [Frame] and is a formatted unit of [data] carried by a [Packet switching] [network]. 

[{$pagename}] consists of control information and user [data], which is also known as the [payload]. Control information provides data for delivering the [payload], for [example]: source and destination network addresses, error detection codes, and sequencing information. Typically, control information is found in [{$pagename}] headers and trailers.

%%information
When referencing the message at the [OSI-Model] [Data-link Layer], where the [MAC Address] is used, the entire [message] is called a [Frame].\\
When referencing the [message] art the [Network Layer], where the [IP Address] is used, then the message is called a [Packet]

[communications] links that do not support [{$pagename}], such as traditional [Point-to-Point Protocol] [telecommunications] links ([Circuit switching]), simply transmit [data] as a [bit] stream. When [data] is formatted into [{$pagename}], [packet switching] is possible and the bandwidth of the [communication] medium can be better shared among users than with [circuit switching].


!! [{$pagename}] and [Datagram]
[{$pagename}] and [Datagram] are generally the same. Some folks will be define a [{$pagename}] as any [data] on a [Reliable protocol] or [Unreliable protocol] where a [Datagram] is used only on a [Unreliable protocol]. We generally see the two used interchangeably.  

!! [{$pagename}] [eDirectory] ([NCP Packet])
[NCP Packet] is a [{$pagename}] as used in [eDirectory] and [Netware Core Protocol] ([NCP])
