1. Layers

1.1. Application Layer

1.1.1. 1. The software that the user interacts with

1.1.2. 2. Allows applications to request network services.

1.1.3. 3. Firefox, Chrome, etc...

1.1.4. 4. First Layer to receive a command

1.2. Presentation Layer

1.2.1. 1. Converts data so that systems that use different data formats can exchange information.

1.2.2. 2. it can also be viewed as a translator for the network

1.3. Session Layer

1.3.1. 1. Establishes sessions between network applications.

1.3.2. 2. or to put it in other terms, it allows applications on different machines to establish or terminate a connection.

1.4. Transport Layer

1.4.1. 1.Provides for reliable delivery of packets.

1.5. Network Layer

1.5.1. 1.Handles routing of data across network segments

1.6. Data Link Layer

1.6.1. 1.Provides MAC addresses to uniquely identify network nodes and a means for data to be sent over the Physical layer in the form of packets. Bridges and switches are layer 2 devices.

1.7. Physical Layer

1.7.1. 1. Governs the layout of cables and devices such as repeaters and hubs.
