ISO is an international standard development organization composed of representatives from the national standards organizations of member countries. What does ISO stands for?

• International Standards Organization

• International Standardization Organization

• International Organization for Standardization

• International States Organization

What are the two main protocols working in the transport layer?

• IP

• TCP

• HTTP

• UDP

These are the two sub-layers of the data link layer.

• LLC

• FTP

• MAC

• ARP

It is a protocol or procedure that connects an ever-changing Internet Protocol (IP) address to a fixed physical machine address, also known as a media access control (MAC) address, in a local-area network (LAN). 

• DHCP

• DNS

• TCP

• ARP

What do you call the component on the picture?

• Wireless adapter

• Network interface card

• Ethernet port

• RJ45 port

A hub operates under the data link layer (layer 2) of the OSI model and doesn't need further administration as its only function is to copy and forward data to all clients (computers, printers, smart TVs, ETC) connected to it.

• TRUE

• FALSE

It is a sublayer that generally provides the logic for the data link as it controls the synchronization, multiplexing, flow control, and even error-checking functions of DLL (Data Link Layer).

• MAC

• LLC

• Session

• TCP

This layer transmits raw bit stream over the communication medium.

• Physical

• Transport

• Data Link

• Network

The transport layer takes data transferred in the session layer and

breaks it into ____ on the transmitting end or reassembles it back to data in the receiving end.

• packets

• frames

• bit stream

• segments

Each layer of the OSI model handles information referred to as a Protocol Data Unit (PDU). In Layer 4, the PDU of the Transport Layer is referred to as a segment based on TCP (Transmission Control Protocol) and with UDP (User Datagram Protocol) PDU is referred to as a datagram.

• TRUE

• FALSE
