made up of a wireless modem, a computer or two, phones, printers, tablets, etc., and revolves around one person in one building.

• PAN

• LAN

• WAN

breaks up packets into frames and sends them from source to destination.

Which of the following layers of the OSI model contains the hardware elements of networking such as Ethernet cables, COAX cables, and repeaters?

• Physical Layer

• Data Link Layer

• Network Layer

• Transport Layer

True or false : WAN connects computers together across longer physical distances.

• True
• False

responsible for opening sessions, ensuring they remain open and functional while data is being transferred, and closing them when communication ends

• Transport Layer

• Application Layer

• Session Layer

• Presentation Layer

connect groups of computers and low-voltage devices together across short distances (within a building or between a group of two or three buildings in close proximity to each other) to share information and resources.

NGSS.HS-PS4-5

has two main functions. One is breaking up segments into network packets, and reassembling the packets on the receiving end. The other is routing packets by discovering the best path across a physical network.

It is responsible for reassembling the segments on the receiving end, turning it back into data that can be used by the session layer.

What is layer 6 of the OSI model?

• Spooky

• Presentation

• Session

• Transport

What is layer 7 of the OSI model?

• Application

• Presentation

• Session

• Transport
