An electrical signal, which runs through the copper wire found inside, covered with aluminum foil to prevent interference. One electric pulse will represent 1 and the absence 0.

A 01000001

The coaxial transmits an electrical signal, which runs through the copper wire found inside, covered with aluminum foil to prevent interference. One electric pulse will represent 1 and the absence 0.

The light produced by diode or laser, travels through the core due to the reflection occurring on the cover, light on will represent 1 and off 0.

These WIRELESS do not require wires to transmit signals, but use radio or infrared to send packets (data set) through the air.

OSI Model

Application Layer: Provides or serves as the window for the user of the OSI Model.

-Provides communication between two application processes, such as application programs, network applications, etc.

-Provides communications aspects for specific applications among networkers: network management, file transfer protocol (ftp), etc.

Presentation Layer: Translate the format and syntax assigned to data for transmission on the network.

-Determines the format of the data without regard for meaning or semantics.

-Set Independence to application processes considering the differences in data representation.

-Provides services to the application layer to interpret the meaning of the data exchanged.

-Operates exchange.

-Operates visualization.

Session Layer: provide the services used by the organization and synchronization of the dialogue between users and management and data exchange.

-Set the start and end of the session.

-Session recovery.

-Control of the dialogue; establishes the order in which messages should flow between end users. -Reference devices by name rather than by address.

-Allows you to write programs that run on any network installation.
