Intro to IP

It is the user interface that internet users interact with to send or receive data through email, online games, peer to peer file transfer, and other applications.

• Application Layer

• Presentation Layer

• Data Link Layer

• Network Layer

When the device can transmit and receive information simultaneously, such as in phone conversation.

• single mode

• half duplex mode

• full-duplex mode

• half and full duplex mode

It consists of the physical components in a Local Area Network (LAN) such as networking hardware and Ethernet cables.

• Application Layer

• Presentation Layer

• Physical Layer

• Network Layer

It is an abstract description for layered communications and computer network protocol design.

• Open System Interconnection

• Operating System Interconnection

• Open System Interconnect

• Open Systematized Interconnection

It is also known as the physical address of a computer 48-bit address burnt onto the network interface card (nic).

• MAC Address

• TCP/IP

• IP Address

• HTTP

It is a layer that ensures that a transmission occurs without any errors.

• Application Layer

• Presentation Layer

• Data Link Layer

• Network Layer

It establishes a "mechanism for opening, closing and managing a session between end-user application processes and responses".

• Application Layer

• Presentation Layer

• Data Link Layer

• Session Layer

One device transmits at a time until all the information has been completely sent.

• single mode

• half duplex mode

• full-duplex mode

• half and full duplex mode

This layer does not only define how data is sent, but also provides validation and firewall security.

• Application Layer

• Presentation Layer

• Transport Layer

• Network Layer

It seeks for the best-known path to route information to reach its destination similar to searching for an address on a GPS.
