Computer Networking Chapter 1

OSI and TCP/IP Stack

A communication straegy called windowing is used at the —— layer of the OSI model

Transport

Bits and units of data in the —— layer

Physical

Packets are units of data in the —- layer

Network

Segments are units of data in the —- layer

Transport

The application layer in TCP/IP Stack is equivalent to what on the OSI Model

The application, presentation and session layers

the —- layer defines how bits are represented on the medium

Physical

The —- layer defines how two devices should encode, encrypt, and compress data

Presentation

the —- layer defines wiring standards for connectors and jacks

Physical

The —- layer has two sublayers, Mac and LLC

Data Link

The —- layer is responsible for logical addressing, packet switching, circuit switching and message switching

Network

The —- layer provides flow control and error handeling

Transport or Data link

The —- layer provides protocols that allow software to send and receive information and present meaningful data

The —- layer routes packets by discovering the best path across a physical network

Network

The —- layer sets up, maintains, and tears down communication channels

Session

The —- layer takes data transferred in the session layer and breaks it into ‘segments; on the transmitting end. it is responsible for reassembling the segments on the receiving end, turning it back into data that can be used by the session layer

Transport

Units of data in the Data Link Layer are called —-

Frames`.
