Layer |
What It Does |
---|---|
Application Layer |
The application layer is what the user of the computer will see
and interact with. This layer is the "Application" that
the programmer develops. |
Presentation Layer |
The Presentation Layer is involved in formatting the data into
a human-readable format, and translating different languages,
etc... |
Session Layer |
The Session Layer will maintain different connections, in case
a single application wants to connect to multiple remote sites (or
form multiple connections with a single remote site). |
Transport Layer |
The Transport Layer will handle data transmissions, and will
differentiate between Connection-Oriented transmissions (TCP) and
connectionless transmissions (UDP) |
Network Layer |
The Network Layer allows different machines to address each
other logically, and allows for reliable data transmission between
computers (IP) |
Data-Link Layer |
The Data-Link Layer is the layer that determines how data is
sent through the physical channel. Examples of Data-Link protocols
are "Ethernet" and "PPP". |
Physical Layer |
The Physical Layer consists of the physical wires, or the
antennas that comprise the physical hardware of the transmission
system. Physical layer entities include WiFi transmissions, and
100BaseT cables. |
