!!! Overview
[{$pagename}] is a digital [data] transmission unit in computer [networking|Network] and [telecommunications].
[{$pagename}] typically includes [{$pagename}] synchronization features consisting of a sequence of [bits] or symbols that indicate to the receiver, the beginning, and end of the [payload] [data] within the stream of symbols or [bits] it receives. If a receiver is connected to the system in the middle of a [{$pagename}] transmission, it ignores the [data] until it detects a new [{$pagename}] synchronization sequence.
[{$pagename}] encapsulates a [packet].
%%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]
%%
!! [OSI-Model], a [{$pagename}] is the [Protocol Data Unit] at the [Data-link Layer].
[{$pagename}]s are the result of the final layer of encapsulation before the [data] is transmitted over the [Physical Layer].
[{$pagename}] is "the unit of transmission in a link layer protocol, and consists of a link layer header followed by a [packet]."
Each [{$pagename}] is separated from the next by an [InterFrame Gap].
[{$pagename}] is a series of [bits] generally composed of framing [bits], the [packet] [payload], and a [Frame Check Sequence] ([FCS]).
!! [{$pagename}] [Examples]
[Examples] are:
* [Ethernet] [{$pagename}]s
* [Point-to-Point Protocol] ([PPP]) [{$pagename}]s
* [Fibre Channel] [{$pagename}]s
* V.42 modem [{$pagename}]s
In [telecommunications], specifically in [Time-Division Multiplex] ([TDM]) and [Time-Division Multiple Access] ([TDMA]) variants, a [frame] is a cyclically repeated [data] [block] that consists of a fixed number of time slots, one for each logical [TDM] channel or [TDMA] transmitter. In this context, a frame is typically an entity at the physical layer. TDM application examples are [SONET]/[SDH] and the [ISDN] circuit switched B-channel, while [TDMA] examples are the [2G] and [3G] circuit-switched cellular voice services. The [{$pagename}] is also an entity for time-division duplex, where the mobile terminal may transmit during some time slots and receive during others.
Often, [{$pagename}] of several different sizes are nested inside each other.
For example, when using [Point-to-Point Protocol] ([PPP]) over [Asynchronous Operation] serial [communication], the eight [bits] of each individual byte are framed by start and stop [bits], the [payload] [data] bytes in a network [packet] are framed by the header and footer, and several [packets] can be framed with frame boundary [Octet].
