NETWORKING QUIZ 5

Application Layer

The layer of the OSI model that functions as human-interaction layer, where you can access the network services.

Presentation Layer

The layer of the OSI model that defines the format of data on the network.

ISO (International Organization for Standardization)

The organization that created the OSI model.

Network Layer

The layer of the OSI model that decides which physical path the data will take.

Transmission Medium

The physical channel used for transmission to ensure data communication.

OSI Model

A conceptual model which enables diverse communication systems to communicate using standard protocols.

Physical Layer

The layer of the OSI model that transmits raw bit stream over the physical medium.

Encapsulation/Decapsulation

Completing one round trip of how data flows through the 7 layers on both sides using the transmission medium.

Session Layer

The layer of the OSI model that maintains connections and is responsible for controlling ports and sessions.

Transport Layer

The layer of the OSI model that transmits data using transmission protocols including TCP & UDP.

Data Link Layer

The layer of the OSI model where the sender makes the frames while the receiver opens the frame.

Internet Layer

The layer in the TCP/IP that functions mainly about IP addressing and routing.

Packet Switching

The method for sending data from one device to another across the internet.

Link Layer (Network Access Layer)

The layer in the TCP/IP that has the main functions: frame making, MAC addressing, frame switching and physical cabling.

TCP (Transmission Control Protocol)

It is designed to send packets across the internet and ensure the successful delivery of data.

IP (Internet Protocol)

The default method of data communication on the Internet.

API (Application Programming Interface)

A communications standard that enables applications to exchange messages.

Protocol

Defines how devices should transmit data and enables communication over long distances.

TCP/IP Model

The network model that helps determine how computers connect to the internet and transmit data.

Physical Path

The actual hardware/medium transmitting data: cables, NICs, connectors, wireless signals.

Logical Path

The path using programming, encapsulation, and protocols.

Client

A device or application that requests services from a server.

Server

A computer or software providing resources/services to others.

Sender

The element in the OSI model that initiates a communication request.
