Chapter Outline

Transmission Modes as outlined in section 17.1 are:

• Simplex, Half-Duplex, Full-Duplex

• Single, Double, Triple

• Unidirectional, Bidirectional, Multidirectional

• Synchronous, Asynchronous, Isochronous

What are Protocols as discussed in section 17.2?

• Protocols are a set of rules governing data communication.

• Protocols are a type of hardware device.

• Protocols are a programming language.

• Protocols are a type of software application.

The Protocol stack mentioned in section 17.3 is described as:

• A layered architecture with specific protocols at each layer

• A single protocol handling all communication

• A decentralized network of protocols

• A proprietary protocol stack unique to the company

The TCP/IP Protocol Suite according to section 17.4 is:

• A set of communication protocols used for the Internet and similar networks

• A type of computer hardware

• A programming language

• A database management system

Explain the Ethernet protocol stack as per section 17.5.

• The Ethernet protocol stack consists of multiple layers including the physical layer, data link layer, and network layer.

• The Ethernet protocol stack is a single-layer protocol focusing only on the physical layer.

• The Ethernet protocol stack is a two-layer protocol focusing on the data link and network layers.

• The Ethernet protocol stack is a three-layer protocol focusing on the application, transport, and network layers.

What are the Application-layer protocols associated with TCP/IP in section 17.6?

• HTTP, FTP, SMTP

• TCP, IP, UDP

• ARP, RARP, ICMP

• Ethernet, Token Ring, FDDI

Peer-to-peer file sharing is discussed in section 17.7.

• True

• False

What is circuit switching in telecommunications?

• A method of communication where a dedicated communication path is established between two parties.

• A technique for data transmission where data is sent in packets over a shared network.

• A wireless communication method using radio waves.

• A method of data encryption for secure communication.

In circuit switching, what is established between two nodes for the entire duration of a connection?

True or False: In circuit switching, the circuit can be used for other purposes while a call is ongoing.

• True

• False
